If 23 fifth grade textbooks were used for the tower and the tower was 57. 1 cm tall, how many sixth grade textbooks were used?
Answers
If 23 fifth grade textbooks were used for the tower and the tower was 57. 1 cm tall, how many sixth grade textbooks were used?
To find out how many sixth grade textbooks were used, divide 57.1 cm by the height of one sixth grade textbook. Then multiply that number by 23 to get the total number of sixth grade textbooks used.
If you want to find out how many sixth grade textbooks were used for the tower, you first have to calculate the height of one sixth grade textbook. Once you have that measurement, you can divide 57.1 cm by that height to get the number of sixth grade textbooks used in the tower. To get the total number of textbooks used, you then need to multiply the number of textbooks per tower by 23, since 23 fifth grade textbooks were used. In other words, if the height of one sixth grade textbook is h, the number of sixth grade textbooks used is (57.1 cm / h) * 23. This equation gives you the number of sixth grade textbooks used, based on the height of one sixth grade textbook and the total height of the tower.

Answers
The lateral area of this paper weight is 61.42 sq inches.
What is lateral surface area?Every solid object's lateral area may be calculated using the lateral area formula. Every figure's lateral area only includes the non-base faces. Calculating the lateral surface area of various forms, such as a cuboid, cube, cylinder, cone, or sphere, is made easier with the use of lateral area formulae. The object's base and the face parallel to the base are not included in the lateral area.
The surface area of the composite figure is the addition of the area of all the shapes.
The area of triangle with height 3.5 in is:
A1 = 1/2(6.5)(3.5)
A1 = 11.375 sq. in.
There are two such triangles thus, 2A1 = 2(11.375) = 22.75.
The area of the two triangle with height 6.5 in is:
A2 = 2(1/2)(4.3)(6.5) = 27.95 sq. in.
The area of the rectangle is:
A3 = (l)(w)
A3 = (6.5)(4.2) = 27.3 sq. in.
The total lateral area is:
LA = 11.375 + 22.75 + 27.3 = 61.42 sq inches.

Answers
The graph of quadrilateral ABCD is attached below and it's area is 25.5 squared units
What is the graph and area of ABCDTo graph the vertices of the quadrilateral ABCD, we need to use a graphing calculator to find the sides and then the area can be calculated as;
We can use the Shoelace Formula to find the area of the quadrilateral. The Shoelace Formula is based on the idea of using the coordinates of the vertices of the polygon to calculate its area.
The formula is:
Area = 1/2 * |(x1y2 + x2y3 + ... + xny1) - (y1x2 + y2x3 + ... + ynx1)|
where (x1,y1), (x2,y2), ..., (xn,yn) are the coordinates of the vertices of the polygon in order, either clockwise or counterclockwise.
Using this formula, we get:
Area = 1/2 * |(13 + 2(-3) + 01 + (-3)4) - (42 + 30 + (-3)(-3) + 11)|
Area = 1/2 * |(-3 - 6 - 12 - 12) - (8 + 0 + 9 + 1)|
Area = 1/2 * |-33 - 18|
Area = 1/2 * 51
Area = 25.5

The center of an ice rink is located at (0, 0) on a coordinate system measured in meters. Susan is skating along a path that can be modeled by the equation y = 6x – x2 – 5. Luke starts at (10, –21) and skates along a path that can be modeled by a quadratic function with a vertex at (8, –9). If the rink is a circle with a radius of 35 meters, which statement best interprets the solution(s) of a system of equations modeling the paths of the skaters?
The skaters’ paths intersect once, but that point is outside the rink.
The skaters’ paths intersect once, and that point is inside the rink.
The skaters’ paths intersect twice, but only one of those points is inside the rink.
The skaters’ paths intersect twice, and both points are inside the rink.
Answers
Answer:
Option C: The skaters path intersect twice, but only one of those points is inside the rink.
Step-by-step explanation:
Coordinates of center of ice rink: (0,0) Radius of ice rink circle = 35 m
We know that the equation of a circle with center coordinates (a,b) and radius of (r) is given as; (x - a)² + (y - b)² = r²
Thus, the total area on which the skaters are skating will be given by the equation;
x² + y² = 35²
Now, we are told the path along which Susan is skating is modeled by the equation: y = 6x - x² - 5
While Luke starts at (10, –21) and skates along a path that can be modeled by a quadratic function with a vertex at (8, –9)
From equation of a parabola, the path along which like is skating can be modeled by;
(x - 8)² = 4a(y + 9)
To find a, we will substitute the coordinate started at to get;
(10 - 8)² = 4a(-21 + 9)
4 = 4a × -12
Divide both sides by 4 to get;
a = -1/12
Thus;
(x - 8)² = 4(-1/12)(y + 9)
(x - 8)² = (-1/3)(y + 9)
This gives: 3(x - 8)² = -(y + 9)
I've drawn the graph on demos and attached it.
From the graph we can see that the skaters points intersect twice but one is inside the rink circle while the other is outside the rink circle. The point at which they intersect outside the rink was slightly cropped out because of size. But it is clearly seen that they are both approaching point of intersection.
Thus, correct answer is Option C.

the answer is 147
Step-by-step explanation:
I have attached a picture with the work. Hope this helps :)
The answer is 147 0 Remainder
EXPLANATION: MY A$* (not that hard lol)
Step 1:
Start by setting it up with the divisor 3 on the left side and the dividend 441 on the right side like this:
Step 2:
The divisor (3) goes into the first digit of the dividend (4), 1 time(s). Therefore, put 1 on top:
Step 3:
Multiply the divisor by the result in the previous step (3 x 1 = 3) and write that answer below the dividend.
Step 4:
Subtract the result in the previous step from the first digit of the dividend (4 - 3 = 1) and write the answer below.
Step 5:
Move down the 2nd digit of the dividend (4) like this:
Step 6:
The divisor (3) goes into the bottom number (14), 4 time(s). Therefore, put 4 on top:
Step 7:
Multiply the divisor by the result in the previous step (3 x 4 = 12) and write that answer at the bottom:
Step 8:
Subtract the result in the previous step from the number written above it. (14 - 12 = 2) and write the answer at the bottom.
Step 9:
Move down the last digit of the dividend (1) like this:
Step 10:
The divisor (3) goes into the bottom number (21), 7 time(s). Therefore put 7 on top:
Step 11:
Multiply the divisor by the result in the previous step (3 x 7 = 21) and write the answer at the bottom:
Step 12:
Subtract the result in the previous step from the number written above it. (21 - 21 = 0) and write the answer at the bottom.
You are done, because there are no more digits to move down from the dividend.
The answer is the top number and the remainder is the bottom number.
Therefore, the answer to 441 divided by 3 calculated using Long Division is:

Answers
The measure of the lengths of the following line segments using online ruler are given as follows:
KL = 5.11cm or = 51.1mm
FG = 8.67cm or = 86.7mm
Length is a physical quantity that refers to the measurement of the extent of an object or distance between two points. It is usually measured in units such as meters, centimeters, or feet.
A line segment is a part of a line that is bounded by two distinct endpoints. It is the shortest distance between two points on a straight line.
To convert cm to mm, we multiply by 10 because there are 10 millimeters in 1 centimeter.
Therefore, to convert 5.11 cm to mm, we can multiply 5.11 by 10:
5.11 cm * 10 = 51.1 mm
So, 5.11 cm is equal to 51.1 mm.
Also to convert 8.67 cm to mm, we can multiply 8.67 by 10:
8.67 cm * 10 = 86.7 mm
So, 8.67 cm is equal to 86.7 mm.

3.6 You have a single piece remaining, 8 points from home, and it is your roll. Your opponent will surely go out if he or she gets another turn. Show that p (your winning) <1/2 , so that a double is not called for. Then explain why this does not contradict the result stated in Exercise 3.1 - namely that the expected count on a backgammon roll is 8 6 1 , exceeding the 8 points you need to win.
Answers
a) result does not contradict
To show that p(your winning) <1/2, we need to consider that the last piece you have on your board could land on various positions. Depending on the position, your opponent could end up winning even if you land a higher value on the dice. Therefore, the probability of your winning is less than 1/2. This shows that a double is not called for.Exercise 3.1 states that the expected count on a backgammon roll is 8 6 1, exceeding the 8 points you need to win. This is true since the expected count means the average count you are expected to land on if you roll the dice. It does not mean that every roll will result in a count higher than 8, and it does not mean that you will always win. The expected count is simply a statistical measure of the possible outcomes of rolling the dice. Therefore, this result does not contradict the fact that p(your winning) <1/2.

In the figure, three lines intersect at point P. If x = 65 and y = 75, what is the value of z?
Answers
The value of angle Z is 40 degrees. (Option 3). In this problem, we are given that three lines intersect at point P and we need to find the value of angle Z.
We know that angle X is 65 degrees and angle Y is 75 degrees. We also know that all six angles formed by the intersection of the three lines add up to 360 degrees.
Using these facts, we can set up an equation as
2X + 2Y + 2Z = 360.
We can simplify this equation to
X + Y + Z = 180.
We can then substitute the given values of X and Y to get
65 + 75 + Z = 180.
Simplifying this equation, we get Z = 40, which means Z is equal to 40 degrees.

In its January 25, 2012, issue, the Journal of the American Medical Association (JAMA) reported on the effects of overconsumption of low, normal, and high protein diets on weight gain, energy expenditure, and body composition. Researchers conducted a single blind, randomized controlled trial of 25 U. S. Adults. The subjects were healthy, weight-stable, male and female volunteers, aged 18 to 35 years. All subjects consumed a weight-stabilizing diet for 13 to 25 days. Afterwards, the researchers randomly assigned participants to diets containing various percentages of energy from protein: 5% (low protein), 15% (normal protein), or 25% (high protein). The subjects were not aware of the specific protein level diet to which they were assigned. On these diets the researchers overfed the participants during the last 8 weeks of their 10 to 12 week stay in the inpatient metabolic unit. The goal was to investigate the effect of overconsumption of protein on weight gain, energy expenditure, and body composition. What is the purpose of random assignment in this experiment?
a. To generalize the experiment results to a larger group
b. To avoid bias
c. To produce treatment groups with similar characteristics
d. To control for confounding variables
Answers
Random assignment in this experiment is important to avoid bias.
By randomly assigning participants to diets with different levels of protein, the researchers are ensuring that any differences in outcomes are due to the diet, and not because of any individual characteristics of the participants. Random assignment helps to ensure that the groups being compared in the experiment are similar and that any differences seen in outcomes are due to the protein level and not other factors. Random assignment helps to eliminate any bias that could be introduced if the participants were assigned to diets based on their own characteristics. This helps to ensure that the results of the experiment are valid and accurate.

Help me ill give you brainliest and extra points Find the average rate of change of g(x)=-x²+4x+2 from x=3 to x=7
Answers
The average rate of change of g(x) from x = 3 to x = 7 is -5.
To find the average rate of change of the function g(x) = -x² + 4x + 2 over the interval [3, 7], we need to calculate the change in the function values over this interval and divide by the length of the interval.
The change in the function values between x = 3 and x = 7 is:
g(7) - g(3) = (-7² + 47 + 2) - (-3² + 43 + 2) = (-49 + 28 + 2) - (9 + 12 + 2) = -20
Therefore, the average rate of change of g(x) over the interval [3, 7] is:
average rate of change = change in function values / length of interval
= -20 / (7 - 3)
= -5
This means that on average, the function g(x) decreases by 5 units for every 1 unit increase in x over the interval [3, 7].

Answers
Tom will arrive in London at 4.10 pm, after travelling 140 miles at an average speed of 50 mph.
The formula to calculate the time taken is: Time = Distance/Speed
Using Tom's assumption that the coach is travelling at an average speed of 50 mph, the time taken for the journey from Newport to London can be calculated as follows:

Mr. Tomas is making a rectangular concrete pad for shed. The area of a pad is 17. 5 square yards. The length of the pad is 5 yards. What is the width of the pad?
Answers
If the area of a pad is 17. 5 square yards, the length of the pad is 5 yards, the width of the pad is 3.5 yards.
The formula for the area of a rectangle is:
Area = length x width
We know that the area of the pad is 17.5 square yards, and the length is 5 yards. We can use this information to solve for the width.
Let's substitute the values we know into the formula:
17.5 = 5 x width
To solve for the width, we need to isolate it on one side of the equation. We can do this by dividing both sides by 5:
17.5/5 = width
Simplifying the left side gives:
3.5 = width
In conclusion, Mr. Tomas should make a rectangular concrete pad that is 5 yards long and 3.5 yards wide to have an area of 17.5 square yards.

A yoga instructor collected student data. He found that students who had less sleep did not tend to burn more or fewer calories during class. What can he conclude?
1)There is no correlation between amount of sleep and number of calories burned.
2)There may or may not be causation. Further studies would have to be done to determine this.
3)There is a correlation between amount of sleep and number of calories burned. There is probably also causation. This is because there is likely an increase in the number of calories burned with an increase in the amount of sleep
Answers
The correct answer is option 1) "There is no correlation between the amount of sleep and the number of calories burned."
Based on the information provided, the yoga instructor can conclude that there is no correlation between the amount of sleep and the number of calories burned during class. Therefore, the correct answer is
option 1) "There is no correlation between the amount of sleep and the number of calories burned."
Option 2) suggests that further studies would be needed to determine causation, but since there is no correlation found in this study, there is no basis for further investigation into causation.

A cylinder has a volume of 72 cubic inches. What is the volue of a cone with the same height and radius as the cylinder
Answers
A cone with the same height and radius as a cylinder has a volume of 24 cubic inches.
If a cylinder has a volume of 72 cubic inches, we can use the formula for the volume of a cylinder to find its height and radius. The formula for the volume of a cylinder is V = πr^2h, where V is the volume, r is the radius, and h is the height.
So, we have:
72 = πr^2h
We can solve this equation for h:
h = 72/(πr^2)
Now, we can use the formula for the volume of a cone to find the volume of a cone with the same height and radius as the cylinder. The formula for the volume of a cone is V = (1/3)πr^2h, where V is the volume, r is the radius, and h is the height.
So, we have:
V = (1/3)πr^2(72/(πr^2))
Simplifying this equation, we get:
V = 24
Therefore, the volume of a cone with the same height and radius as the cylinder is 24 cubic inches.
