Answer:
Answers
Answer:
24 monkeys are in the trees
Step-by-step explanation:
The only part I don´t know how to do is the 10-square model
You set it up as x/40 and 60/100 and cross multiply
60*40 = 2400
100•x = 100x
2400 divided by 100 is equal too 24
Mr. Parker wants to rent a cargo van for a day. It will cost the daily fee of $50.00 plus $0.35 per mile driven.
Let m = the number of miles Mr. Parker drives for the day. Write an algebraic expression that shows the amount he will pay for the van.
Answers
Answer:
50d * 0.35m
Step-by-step explanation:
so I don't normally do it like this it would normally be 50 * 0.35x. but the days also had a fee unless she doesn't have it for 2 days and only has it one but d is the days she has it and m is the miles driven the * is times
you would have to find out the days she has it unless you don't have that is would be the answer above (if I am wrong I'm sorry)

Step-by-step explanation:
(2/5 - 1/10) x 2^3 - 23/25
(4/10 - 1/10) x 2^3 - 23/25
3/10 x 2^3 - 23/25
3/10 x 8 - 23/25
24/10- 23/25
Find a common denominator: 50
24 x 5 = 120
10x 5 = 50
24/10 = 120/50
23 x 2 = 46
25 x 2 = 50
23/25 = 46/50
120/50 - 46/50 = 74/50

The median is the middle value in the data set. Since there are five values in the data set, the middle value is the third value, which is 35. Therefore, the median of the data set is 35.
To find the mean, we need to add up all the values in the data set and divide by the total number of values:
(3 + 31 + 35 + 36 + 38) / 5 = 28.6
Therefore, the mean of the data set is 28.6.
the median is always the middle number so the median is 35. hope this helps you to remember in the future

Quadrilateral A'B′C′D′ is the result of dilating quadrilateral ABCD about point P by a scale factor of 2.
Answers
Answer:
Line CD and C'D' are both perpendicular to the x-axis.
The dilated quadrilateral A'B'C'D' is created by enlarging quadrilateral ABCD about point P using a scale factor of 2. The lengths of the sides are multiplied by 2, while the angles remain the same.
The dilated quadrilateral A'B'C'D' is formed by enlarging quadrilateral ABCD about point P using a scale factor of 2.
To understand the concept, let's break it down step-by-step: 1. A dilation is a transformation that changes the size of a figure while keeping its shape intact.
2. In this case, the original quadrilateral ABCD is being dilated, resulting in a new quadrilateral A'B'C'D'.
3. The point P serves as the center of dilation, around which the quadrilateral is enlarged or reduced.
4. The scale factor of 2 means that the lengths of the sides of the original quadrilateral are multiplied by 2 to obtain the lengths of the sides of the dilated quadrilateral.
5. For example, if side AB has a length of 5 units in ABCD, then side A'B' will have a length of 10 units in A'B'C'D' since 5 multiplied by 2 is 10.
6. Similarly, all other sides of the dilated quadrilateral will be twice the length of the corresponding sides in the original quadrilateral.
7. The angles of the quadrilateral will remain the same, as dilations only affect the lengths of the sides, not the angles. 8.
The resulting dilated quadrilateral will be similar to the original quadrilateral, meaning that the corresponding angles will be equal, and the corresponding sides will be proportional.
So, in summary, the dilated quadrilateral A'B'C'D' is created by enlarging quadrilateral ABCD about point P using a scale factor of 2. The lengths of the sides are multiplied by 2, while the angles remain the same.

Use the Midpoint Rule with \(n=5\) to estimate the volume obtained by rotating about the y-axis the region under the curve \(y=\sqrt{1+x^3}\), \(0\leq x\leq 1\).
Answers
To estimate the volume using the Midpoint Rule with \(\displaystyle n=5\), we need to divide the interval \(\displaystyle 0\leq x\leq 1\) into \(\displaystyle n\) subintervals of equal width. Since \(\displaystyle n=5\), each subinterval will have a width of \(\displaystyle \Delta x=\frac{1-0}{5}=\frac{1}{5}\).
Now, let's calculate the volume using the Midpoint Rule. The formula for the volume obtained by rotating about the y-axis is:
\(\displaystyle V\approx 2\pi \sum _{i=1}^{n}y_{i}\Delta x\)
where \(\displaystyle y_{i}\) represents the value of the function \(\displaystyle y=\sqrt{1+x^{3}}\) evaluated at the midpoint of each subinterval.
First, let's find the midpoints of the subintervals. Since the width of each subinterval is \(\displaystyle \Delta x=\frac{1}{5}\), the midpoint of the \(\displaystyle i\)-th subinterval is given by:
\(\displaystyle x_{i}=\frac{\Delta x}{2}+\left( i-\frac{1}{2}\right) \Delta x=\frac{1}{10}+\left( i-\frac{1}{2}\right) \frac{1}{5}\)
Substituting \(\displaystyle x_{i}\) into the function \(\displaystyle y=\sqrt{1+x^{3}}\), we obtain:
\(\displaystyle y_{i}=\sqrt{1+\left( \frac{1}{10}+\left( i-\frac{1}{2}\right) \frac{1}{5}\right) ^{3}}\)
Now, we can calculate the approximate volume using the Midpoint Rule:
\(\displaystyle V\approx 2\pi \sum _{i=1}^{5}y_{i}\Delta x\)
Substituting the values of \(\displaystyle y_{i}\) and \(\displaystyle \Delta x\) into the formula, we can evaluate the sum and compute the estimated volume.

It's 15 because multiplying it by 8 instead of dividing it gives you 120.

c^2﹣b^2 = a
now, plug in our numbers!
9^2 - 3^ = a
9^2 = 81
3^ = 9
subtracting 81 and 9, we get 72!
