Sara had 136 dollars to spend on 8 books. After buying them she had 16 dollars. How much did each book cost ?

Answer: 8.

Step-by-step explanation:

The solve this expression, you have to use PEMDAS rules. PEMDAS stands for Parentheses, Exponents, Multiplication, Division, Addition, and Subtraction. This means that the first thing that you have to do is what is in the parentheses. This is [6 + (4 x 3)]. As I explained before, you have to do multiplication before addition, thus you have to do 4 x 3 first. This is 12, so now you have 6 + 12 in parentheses. Add this to get 18. Now that you are done solving the things in parentheses, you can use the 20 that is outside of the parentheses. You then have 20 - 12. This is 8, so your answer is 8.

Answer:

The surface area of a rectangular prism can be calculated using the formula:

Surface Area = 2lw + 2lh + 2wh

where l, w, and h are the length, width, and height of the rectangular prism, respectively.

Given the dimensions of the rectangular prism as:

Length (l) = 38

Width (w) = 20

Height (h) = 20

Substitute the values in the formula to get:

Surface Area = 2lw + 2lh + 2wh

Surface Area = 2(38)(20) + 2(38)(20) + 2(20)(20)

Surface Area = 1520 + 1520 + 800

Surface Area = 3840 square units

Therefore, the surface area of the rectangular prism is 3840 square units.

Answer:

3840

Step-by-step explanation:

A=2(wl+hl+hw)=2·(20·38+20·38+20·20)=3840

Answer:

it will take 1120 bushels of grapes to make 3200 quarts of jelly.

Step-by-step explanation:

We can use a proportion to solve this problem. If 10.5 bushels of grapes make 30 quarts of jelly, then we can write:

10.5 bushels / 30 quarts = x bushels / 3200 quarts

where x is the number of bushels of grapes needed to make 3200 quarts of jelly.

To solve for x, we can cross-multiply and simplify:

10.5 bushels * 3200 quarts = 30 quarts * x bushels

33600 bushels-quarts = 30x bushels-quarts

Dividing both sides by 30 bushels-quarts, we get:

x = 33600 bushels-quarts / 30 bushels-quarts

x = 1120 bushels

Answer:

The image coordinates of K′ if the preimage is reflected across y = −7 is (-4, -8)

Credit: first answer by MrRoyal

The coordinates of point M' if the preimage is reflected

across y = −3 would be M'(-1, -2).

There are three types of translations -

reflection

rotation

dilation

Given is that a Polygon JKLM is drawn with vertices J(−4, −4), K(−4, −6), L(−1, −6), M(−1, −4). We have to find the image coordinates of M′ if the preimage is reflected across y = −3.

The reflection of point (x, y) reflected across the line y = a is (x, 2a - y)

So, we can write the coordinates of point M' if the preimage is reflected

across y = −3 would be -

M(-1, -4) → M'(-1, 2 x - 3 + 4)

M(-1, -4) → M'(-1, -2)

Therefore, the coordinates of point M' if the preimage is reflected

across y = −3 would be M'(-1, -2).

73*4 would = 292. Therefore, none of the following 'simplified' expressions would equal to that amount.

Answer: 56

Step-by-step explanation

well you could break up this "shape"into multiple different parts (already broken) you want to find the area of all the shapes then add the areas.

first lets start off with the two triangles at the top the area for a triangle is base x height divided by 2, the base would be  because of the 5 and the 2 at  the edge of the triangle and the height would be 4 because of the 10 at the top minus the 6

for this case we wouldn't divide by 2 because there are 2 triangles, so there is no point. ( 7 X 4 = 28)  

then we would move onto the large rectangle, the area of a triangle is base x height, base=4 height=5 (4 x 5 = 20)

then we move onto the smaller rectangle using the same area formula, base=2 because if you look at the 6 on the top and minus the 4 of the large rectangle. height =3 (2x3=6)

and the last one the small triangle, for this we would use the same formula ( base x height divided by 2) we are dividing by two because there is only 1 triangle. base=2 and height=2 because of the five on the right minus the 3 *height of the smaller rectangle* so

(2X2 divided by 2= 2)

then we add them all up, 28 + 20 + 2 + 6 = 56

Answer:

34,28 ft

Step-by-step explanation:

This figure is formed from a rectangle and a semi-circle

Opposite sides of a rectangle are equal

This figure's perimeter is the sum of all side lengths:

2 sides of 12 ft

1 side of 4 ft

Half of the circumference

d (diameter) = 4 ft

r (radius) = 0,5 × 4 = 2 ft

First, we have to find the half of the circumference (C):

[tex]0.5c = (2\pi \times r[/tex])/2

[tex]0.5c = (2 \times 3.14 \times 2)/2 = 6,28[/tex]

Now, we can find the perimeter of the given figure:

P = 6,28 + 12 + 12 + 4 = 34,28 ft

Step-by-step explanation:

When translating a pre-image, there are some easy tricks you can use to figure out what the coordinates of the image are instead of drawing it out.

When translated to the right, add the number of units translated to the x-value.

This is because, when we move right on a coordinate plane, we move along the x-axis toward the positive numbers.

When translated to the left, subtract the number of units translated to the x-value.

This is because, when we move left on the coordinate plane, we move along the x-axis toward the negative numbers.

When translated up, add the number of units translated to the y-value.

This is because when we move up on the coordinate plane, we move along the y-axis toward the positive numbers.

When translated down, subtract the number of units translated to the y-value.

This is because when we move down on the coordinate plane, we move along the y-axis toward the negative numbers.

This is how I solved this problem. Apply these tricks and you will see that you will get the correct answer.

Answer:

m=100 N=4480 P=1706. Q= 213.25

Step-by-step explanation:

First divide 800/8= 100

100 is M

Undo division for 560x8= 4480

4480 is N

Add 100+560= 660

Solve to equations 6986/8= 873.25

subtract 873.25-660= 213.25

213.25 is Q so undo division 213.25x8= 1706

1706 is P

Add 800+4480+1706= 6986

6986 is the first part of the equation

Add 100+560+213.25= 873.25

873.25 is the answer to the equation making answer that I gave correct

6986/8= 873.25

The formula for the volume of a right prism is given by:

Volume = Base area x Height

In this case, the base of the triangular prism is a triangle, and its area can be calculated using the formula:

Base area = (1/2) x Base x Height

where Base and Height are the dimensions of the triangular base.

So, to find the volume of the cabin, we can use the following steps:

Calculate the area of the triangular base: Base area = (1/2) x Base x Height Base area = (1/2) x 25 ft x 15 ft Base area = 187.5 sq ft

Multiply the area of the base by the height of the prism: Volume = Base area x Height Volume = 187.5 sq ft x 30 ft Volume = 5625 cubic feet

Therefore, the volume of the cabin is 5625 cubic feet.

When you divide a difference by 3, you are essentially finding the average difference between two quantities and then dividing that value by 3.

For example, if you have two numbers a and b, and you want to find the difference between them, you would subtract b from a to get a - b. Dividing this difference by 3 would give you:

(a - b) / 3

This expression represents the average difference between a and b, divided by 3.

For instance, if a = 10 and b = 6, then the difference between a and b is 4. Dividing this difference by 3 gives us:

(10 - 6) / 3 = 4 / 3

Therefore, when you divide a difference by 3, you are finding the average difference between two quantities and then dividing that value by 3.

Answer: 2.26

Step-by-step explanation: The formula for finding out the radius of a cylinder when given the volume and height is (r) = √(V / π × h)

V is the volume, π is equal to 3.14, and h is the height

(r) = √(320/ π × 20)

(r) = √(320/ 3.14 × 20)

(r) = √(320/ 62.8)

(r) = √(5.09)

(r) = 2.256

when you round 2.256 to the nearest hundredth is 2.26 cm
