Answer:
4188.79 yd^3
Step-by-step explanation:
The formula for the volume of a sphere is ...
V = 4/3πr^3
A sphere with a diameter of 20 yards has a radius of 10 yards, so its volume is ...
V = 4/3π(10 yd)^3 = 4000π/3 yd^3 ≈ 4188.79 yd^3
Rounded to tenths, that's approximately 4188.8 yd^3.

The purpose of this task is for students to solve a mathematical problem using points in the coordinate plane. This task also helps lay the foundation for understanding operations on signed numbers without formally introducing those notions, which are not expected until 7th grade (see 7.NS.1). Students will not have the full machinery needed to find distances between two arbitrary points in the plane until they have studied the Pythagorean Theorem in 8th grade. However, it is straightforward for them to find horizontal and vertical distances, which mirrors how one might represent sums and differences of signed numbers on a number line. The solution for the first part shows how these questions can be represented using absolute values (as described in standard 6.NS.C.8), although students are unlikely to make this connection without being asked to do so. If students are asked to solve this problem on their own first, it could be used to launch a discussion of the relationship between the the absolute value of coordinates of points in the plane and their distance to the respective axes.
Please note that students will have to assume that the points have integer coordinates, which is reasonable but worth mentioning.
Solution
The distance between points B and C is 5 units, as indicated below.
We can determine the distance between points B and C by counting the units between the two points since they are on the same vertical line which happens to be a grid line.
We can also note that the coordinates for B are (3,2) and so it is |2| units above the x-axis. Similarly, the coordinates for C are (3,−3), so it is |-3| units below the x-axis. Thus, the distance between B and C is
|2|+|−3|=5
units.
The distance between points D and B is 7 units, as indicated below.
The distance between points D and E is 4 units, as indicated below.
Point C is the only one of points A,…E that is both 4 units away from (−1,−3) and 2 units away from (3,−1). There is another point that satisfies these two criteria (which is the other intersection point of the circle of radius 4 and circle of radius 2 shown below), but it does not have integer coordinates and is not one of the points identified in the task

The vertices of triangle B'C'D' are:

C'(0, 2)
D'(1, -3/2)
What is a triangle?A triangle is a 2-D figure with three sides and three angles.
The sum of the angles is 180 degrees.
We can have an obtuse triangle, an acute triangle, or a right triangle.
We have,
To find the vertices of triangle B'C'D', which is a dilation of triangle BCD with center at the origin and a scale factor of 1/4,
We can follow these steps:
Find the coordinates of the centroid of triangle BCD.
The coordinates of the centroid G are:
[tex]x_G = (x_B + x_C + x_D) / 3 = (4 + 8 + 12) / 3 = 8[/tex]
[tex]y_G = (y_B + y_C + y_D) / 3 = (4 + 14 + 0) / 3 = 6[/tex]
Translate triangle BCD so that its centroid is at the origin.
We can do this by subtracting the coordinates of the centroid from the coordinates of each vertex:
B(4, 4) → [tex]B_1(4 - 8, 4 - 6) = B_1(-4, -2)[/tex]
C(8, 14) → [tex]C_1(8 - 8, 14 - 6) = C_1(0, 8)[/tex]
D(12, 0) → [tex]D_1(12 - 8, 0 - 6) = D_1(4, -6)[/tex]
Dilate the translated triangle [tex]B_1C_1D_1[/tex] by a scale factor of 1/4.
To do this, we can multiply the coordinates of each vertex by 1/4:
[tex]B_1[/tex](-4, -2) → B'(-4 x 1/4, -2 x 1/4) = B'(-1, -1/2)
[tex]C_1[/tex](0, 8) → C'(0 x 1/4, 8 x 1/4) = C'(0, 2)
[tex]D_1[/tex](4, -6) → D'(4 x 1/4, -6 x 1/4) = D'(1, -3/2)
Therefore,
The vertices of triangle B'C'D' are:
B'(-1, -1/2)
C'(0, 2)
D'(1, -3/2)

10) A cat consumes 2 cups of milk every day. How much milk does that cat drink on an average in a week? =
Answer:
4) 11.75 6) 23 10) 14
Step-by-step explanation:
4) To find the mean, you would find the average of all the data. To do that, you add all the numbers together, then divide them by the number of numbers there are. So: (14+14+10+12+11+13+11+11+14+10+13+8)/12=141/12=11.75
6) To find the median, you would find the number in between all the numbers. So: 16,20,22,22,22,24,26,26,28,28,28. The median of all of this would be between 22 and 24, so it would be 23.
10) Since one week has 7 days, and the cat drank 2 cups per day, you can multiply 7 and 2 to get 14, and that would be your answer.

Mallory puts $1.00 in a jar. The following week, she puts 2 times that original amount in the jar. For each of the next six weeks, Mallory continues to double the amout of money she places in her savings jar each week.
Determine if the relationship is linear or nonlinear. Explain your choice using examples with ordered pairs. (week, amount)
We want to see if the relationship between the number of weeks and the money put in the jar is linear or not, we will see that this is not a linear equation (it is exponential).
So a linear relation is something like:
y = a*x + b
Note that for any value of x, an increase of 1 unit gives:
y = a*(x+ 1) + b = (a*x + b) + a
So for increases of 1 unit in the x-value, we have increases of "a" units on the y-value.
In the given situation we have:
In week 1 she puts $1.00 in the jar.In week 2 she puts $2.00 in the jar (now the jar has $3.00 in it)In week 3 she puts $4.00 in the jar (now the jar has $7.00 on it)In week 4 she puts $8.00 in the jar (now the jar has $15.00 on it)and so on.
Writing that as points we have:
(1, $1)
(2, $3)
(3, $7)
(4, $15)
Notice that for equal increases in the x-value, (increases of 1 unit) we don't equal increases in the y-value (first increases by $2, then by $4, etc...) So this is not a linear equation, this is actually exponential.

The relationship of the ordered pair that represents Mallory savings is a nonlinear relationship.
Let x represents the number of weeks, and y represents the amount put in the jar, each week.
So, we have the following highlights for 6 weeks.
Week 1: (1, 1)Week 2: (2,2)Week 3: (3,4)Week 4: (4,8)Week 5: (5,16)Week 6: (6,32)The ordered pairs can then be represented as:
[tex](x,y) = (1,1)(2,2)(3,4)(4,8)(5,16)(6,32)[/tex]
As the x values increase, the y values increase too, but the y values do not increase at a constant rate.
This means that the relationship is not linear; it is an exponential relationship.
Hence, the relationship is a nonlinear relationship.

Answer: 4200? or 10 because there is a minus sign
Step-by-step explanation:
if we start with the parentheses you can see 4 x 15 = 60 and your subtracting 70 minus 60 so it would be 10

Enter your answer as a number, like this: 42
Do not enter units.
HELPPPP PLEASEEEEE
Answer:
The volume in Cubic feet is 60 cft.
Step-by-step explanation:
we have to divide 20 by 120. 120 ÷ 20 = 60. Even though 5 is divisible by 60, we won't be doing that. 60 cft. is the answer.
Hope this helps!
Answer:
it is 500 cubic feet, when it is a triangle or triangular prism we divide it in half since its half a square, 120 inches=10 feet. 10ftx20x1/2=100. 100x5=500

Annette is surveying people in the city about their interest in a new shopping mall. She found that 180 people, or 37.5% of those surveyed, do not want a new mall. How many people did Annette survey?
We want to find the total number of people that Annette surveyed given that we know a percentage and the number that the percentage represents.
We will find that the number of people that Annette survey is 480.
To get the solution:
Let's assume that she surveyed a total of X people.
Then we can write the equivalence:
100% = X
We know that the 37.5% is equivalent to 180 people, then we can write:
37.5% = 180
The two equations are:
100% = X
37.5% = 180
Now we can take the quotient between these two equations to get:
(100%/37.5%) = X/180
Solving for X we get:
(100%/37.5%)*180 = X = 480
So the total number of people surveyed is 480.
Answer:
480 people
180/X × 100 = 37.5%
180 × 100 = 37.5 × X
18000 ÷ 37.5 = 37.5 × x ÷ 37.5
480 people = x
