Answer:
The volume of the cake is:
12 inches x 9 inches x 2 inches = 216 cubic inches
Dividing the volume of the cake by the number of pieces, we get:
216 cubic inches / 18 = 12 cubic inches per piece
Therefore, the volume of each piece is 12 cubic inches.
Answer:
12 inches cubed
Step-by-step explanation:
First we have to find the total volume so we can split it up. We can do this by using the formula LWD = V, where l = length, w = width, and d = depth.
Here, the length is 12, the height is 2, and the depth is 9. We apply the formula:
(12)(2)(9) = 216
Now, we have to split it into 18 separate pieces. We can do this by dividing the total volume (216 inches cubed) by 18.
216/18 = 12
Therefore, each equal piece will be 12 inches cubed

Out of 100 problems on a test,15 problems,or 15% of the problems, have two parts. So far, you have completed 40 problems. If the two-part problems appear throughout the test, about how many of those 40 problems have two parts?
Thus, out of 40 problems, 6 problems will have two parts problems which is 15% of the 40.
Explains about the percentage:The phrase "percent" refers to a number out of 100 or per 100. The term is derived from the Roman expression per centum, which means "by the hundred." Hence, a single percent would be one of those hundred units, and one percent, for every one hundred of anything.
Given data:
Out of 100 problems - 15% have two parts.
Out of 100 problems - 85% will not have two parts.
Thus, out of 40 problems, also 15% will contain two parts.
Then,
Number of two-part problem = 15% of 40
Number of two-part problem = 15 * 40 / 100
Number of two-part problem = 600 / 100
Number of two-part problem = 6
Thus, out of 40 problems, 6 problems will have two parts which is 15% of the 40.

Tommy picked 2 baskets full of apples. One basket weighed 18. 63 kilograms. The
other basket weighed 9. 97 kilograms. How much more did the first basket weigh?
The weight of the first basket full of apples is 8.66 kilograms more as compare to weight of the second basket.
Number of full of apples basket with Tommy = 2
Weight of first basket full of apples = 18.63 kilograms
Weight of second basket full of apples = 9.97 kilograms
Weight of first basket is greater than the weight of the second basket.
More weight in first basket
= Subtract the weight of the second basket from the weight of the first basket
⇒ More weight in first basket = Weight of first basket - Weight of second basket
⇒ More weight in first basket = ( 18.63 - 9.97 ) kilograms
⇒ More weight in first basket = 8.66 kilograms
Therefore, the first basket weighed 8.66 kilograms more than the second basket.

The local movie theater increased its admission price by 18%. If the original admission price was $5.50, how many dollars is the new admission price? sorry for asking another question
Answer:
$6.49
Step-by-step explanation:
The original admission price was $5.50, and it increased by 18%. Let's find 18% of 5.50 and then add it to $5.50, meaning $5.50 would increase by 18% (of itself.)
So 18% of 5.50 = 0.99 ( thats 0.18 x 5.50)
Add the 99 cents (0.99) to $5.50
and then you get $6.49
here is the equation I used:

Researchers conducted a study to determine the relationship between male pattern baldness and risk of myocardial infarction (MI) in men under the age of 60. Cases were men younger than 60 admitted with an MI to one of five hospitals. Controls were men younger than 60 admitted to these hospitals with a different diagnosis. The physicians who cared for the patients were unaware that this study was being conducted. The nurses collecting the data did not know whether the men were cases or controls and they definitely did not know the purpose of the study. The nurses, however, were poorly trained in the use of the male pattern baldness scale. Based on this description (choose one answer):
a. This study is most prone to differential misclassification of exposure status
b. This study is most prone to nondifferential misclassification of disease status
c. This study is most prone to differential misclassification of disease status
d. This study is most prone to nondifferential misclassification of exposure status
Based on the description, this study is most prone to differential misclassification of exposure status. The correct answer is A.
The description of the study suggests that the nurses who collected the data were poorly trained in the use of the male pattern baldness scale. This means that they may have misclassified some men as having male pattern baldness when they did not actually have it, and vice versa.
This misclassification of exposure status (i.e., male pattern baldness) is more likely to be differential because the nurses were unaware of the purpose of the study and did not know whether the men were cases or controls. This means that their misclassification of exposure status is likely to be influenced by the outcome (i.e., MI).
For example, if the nurses believed that male pattern baldness was a risk factor for MI, they may have been more likely to classify cases as having male pattern baldness and controls as not having it, even if this was not accurate. This would result in differential misclassification of exposure status, which can bias the study results. The correct answer is A.

zoe the goat is tied by a rope to one corner of a 15 meter-by-25 meter rectangular barn in the middle of a large, grassy field. over what area of the field can zoe grace of the rope is:
If Zoe the goat is tied to a corner of a rectangular barn measuring 15m by 25m in the middle of a field, Zoe can graze within an area of 2660.5 sqm.
The area of the field that Zoe can graze depends on the length of the rope, which is not given in the problem. However, we can use the Pythagorean theorem to find the length of the diagonal of the barn, which represents the maximum length of the rope.
The diagonal of a rectangle with sides of length 15 meters and 25 meters can be found using the Pythagorean theorem:
diagonal² = 15² + 25²
diagonal² = 225 + 625
diagonal² = 850
diagonal =[tex]\sqrt{850}[/tex] ≈ 29.15 meters
This means that the maximum length of the rope is about 29.15 meters. The area that Zoe can graze is a circle with radius equal to the length of the rope. We can use the formula for the area of a circle to find this area:
Area = π(radius)²
Area = π(29.15)²
Area ≈ 2660.5 square meters
Therefore, the correct answer is approximately 2660.5 square meters

Mrs. Smith wants to add a 2 feet concrete walkway around the edge of the pool.
Write a polynomial expression, in simplified form, that represents the total area of the pool and the walkway. Show and explain how you got the area of the pool and the walkway. 
To find the total area of the pool and the walkway, we can add the areas of the pool and the walkway together.
Let's assume that the pool has dimensions of length L and width W, and that the walkway has a uniform width of 2 feet all around the pool. This means that the dimensions of the pool plus the walkway will be (L + 4) feet by (W + 4) feet, since we add 2 feet on each side.
The area of the pool alone is given by L x W. The area of the pool plus the walkway is then given by (L + 4) x (W + 4). To simplify, we can use FOIL (First, Outer, Inner, Last) method to expand the expression:
(L + 4) x (W + 4) = LW + 4L + 4W + 16
Therefore, the polynomial expression that represents the total area of the pool and the walkway is:
A(L,W) = LW + 4L + 4W + 16
where A(L,W) is the total area of the pool and walkway as a function of the pool's length and width.
1.Start by assuming that the pool has dimensions of length L and width W, in feet.
2.Since Mrs. Smith wants to add a 2-foot walkway around the edge of the pool, we need to add 2 feet to both the length and width of the pool to get the dimensions of the pool plus the walkway. This means that the dimensions of the pool plus the walkway are (L + 2) feet by (W + 2) feet.
3.To find the area of the pool alone, we can simply multiply the length by the width: A_pool = L x W.
4.To find the area of the pool plus the walkway, we need to multiply the length and width of the larger rectangle that includes both the pool and the walkway. This rectangle has dimensions of (L + 2) feet by (W + 2) feet. Therefore, the area of the pool plus the walkway is:
A_total = (L + 2) x (W + 2)
5.We can simplify this expression by using the distributive property of multiplication. We first multiply L by W to get LW. Then, we multiply L by 2 and W by 2 to get 2L and 2W, respectively. Finally, we add 2 x 2 = 4 to account for the extra area added by the walkway. Therefore, the total area of the pool plus the walkway can be written as:
A_total = LW + 2L + 2W + 4
6.Finally, we can rewrite this expression as a polynomial in standard form, by rearranging the terms in descending order of degree:
A_total = LW + 2L + 2W + 4
= LW + 2L + 2W + 0x² + 4
= 0x² + LW + 2L + 2W + 4
So the polynomial expression that represents the total area of the pool and the walkway is:
A(L,W) = LW + 2L + 2W + 4
where A(L,W) is the total area of the pool and walkway as a function of the pool's length and width.

The probability that they will all be non fiction is 0.0667. The solution has been obtained by using hyper-geometric distribution.
What is hyper-geometric distribution?
When sampling from a small population without replacement, the hyper-geometric distribution is a discrete probability distribution that determines the likelihood that an event occurs k times in n trials.
The formula is
P (X = x) = h (x, N, n, k) = [tex]\frac{C_{k,x} * C_{N-k, n-x} }{C_{N,n} }[/tex]
We are given
x = 4
N = 10 + 12 = 22
n = 4
k = 12
Substituting this in the formula, we get
⇒P (X = 4) = h (4, 22, 4, 12) = [tex]\frac{C_{12,4} * C_{22-12, 4-4} }{C_{22,4} }[/tex]
⇒P (X = 4) = h (4, 22, 4, 12) = [tex]\frac{C_{12,4} * C_{10, 0} }{C_{22,4} }[/tex]

Answer:
To find out which cake is the most expensive per serving, we need to calculate the cost per serving for each cake.
The first cake serves 2 people and costs $4.50. So the cost per serving is:
$4.50 ÷ 2 = $2.25 per serving
The second cake serves 8 people and costs $10.00. So the cost per serving is:
$10.00 ÷ 8 = $1.25 per serving
The third cake serves 10 people and costs $20.00. So the cost per serving is:
$20.00 ÷ 10 = $2.00 per serving
Therefore, the first cake is the most expensive per serving, at $2.25 per serving.

(8, −2)
(4, 1)
(4, −1)
(−4, 1)
The location of A using graphs, is at (4, -1).
What are graphs?An organised representation of the data is all that the graph is. It facilitates our understanding of the facts. Data is the term used to describe the numerical information obtained through observation.
The development of a research question is followed by the ongoing observational collection of data. The data is then organised, distilled, categorises, and visually represented.
Here in the question,
Coordinates of A= (8,2)
Now it is dilated by a scale factor of 1/2. So,
New coordinates, A' = (8/2,2/2)
= (4,1)
Now the triangle is reflected over the x-axis.
A' now becomes A" which is (4, -1).
Therefore, the new coordinate of A is (4, -1).

Rachel goes to a shopping mall to buy shirts and pants for her
children. She has a total budget of $200, and she's going to
buy shirts for $25 each and pants for $20 each. Write an
inequality to describe the possible number of shirts and Pants
that Rachel can buy. If Rachel buys 5 Pants, what is the
maximum number of shirts she can buy?
Answer:
4
Step-by-step explanation:
Let x be the number of shirts that Rachel can buy, and y be the number of pants she can buy. Then the cost equation would be:
Cost = 25x + 20y
Since Rachel has a total budget of $200, we can write:
25x + 20y ≤ 200
To find the maximum number of shirts that Rachel can buy if she buys 5 pants, we can substitute y = 5 into the inequality and solve for x:
25x + 20(5) ≤ 200
25x ≤ 100
x ≤ 4
Therefore, Rachel can buy a maximum of 4 shirts if she buys 5 pants.
You pick a card at random. Without putting the first card back, you pick a second card at random.What is the probability of picking a 2 and then picking a number less than 4?
The probability of picking a 2 and then picking a number less than 4will be 0.56%
What is prοbability?By simply dividing the favοrable number οf pοssibilities by the entire number οf pοssible οutcοmes, the prοbability οf an οccurrence can be determined using the prοbability fοrmula. Because the favοrable number οf οutcοmes can never exceed the entire number οf οutcοmes, the chance οf an event οccurring might range frοm 0 tο 1.
The number οf favοurable οutcοmes tο all pοssible οutcοmes οf an event is the ratiο, which is knοwn as prοbability. The number οf gοοd οutcοmes can be represented by the symbοl x fοr an experiment with 'n' number οf οutcοmes. The fοllοwing equatiοn can be used tο determine an event's prοbability.
Yοu pick a card at randοm. Withοut putting the first card back, yοu pick a secοnd card at randοm.
1/13 chance οf picking a 5.
4/51 chance οf picking a 3 οn secοnd draw.
4/(13*51) οf dοing these sequentially = 0.56%
Hence the prοbability will be 0.56%

An ant walked 475 millimeters at a steady
speed. It took the ant 10.0 seconds to walk
that distance. What was the ant's speed?
Write your answer to the tenths place.
millimeters per second
answer:Average velocity is displacement divided by the time over which the displacement occurs. v avg = displacement time = Δ d Δ t = d f − d 0 t f − t 0. Velocity, like speed, has SI units of meters per second (m/s), but because it is a vector, you must also include a direction.

Partition the interval into equal parts. Label the fractions at 0 and 1. Plot the given fraction on the number line
The fractions between 0 and 1, we have represented on a number line, include 1/4, 2/4, and 3/4. All of these have equal intervals of 0.25.
To plot 1/4, 2/4 and 3/4 on the number line, we need to divide the interval between 0 and 1 into four equal parts. Each part will represent 1/4.
We can label the fractions at 0 and 1 as shown below:
0 1/4 2/4 3/4 1
Now we can plot the given fractions on the number line as shown below:
0 1/4 2/4 3/4 1
o o o
1/4 2/4 3/4
We can divide the fractions to get the difference of intervals. This can be done as follows:
2/4-1/4 = 0.25, also:
3/4-2/4 = 0.25.
Any portion of a whole number that is stated as one number multiplied by another is referred to as a fraction. One-half of something, for instance, is represented by the fraction 1/2. Another approach to represent a portion of a full number is with a decimal.1/2 is same as 0.25 as a decimal.
