Tyler bought a shirt from the 25% off rack. It normally costs $16. Here is the money he paid.


A ten dollar bill and two one dollar bills


Why did he pay $12? the options are (Sales Tax, Markup, Interest, Tip, Markdown, and Commission)

Answers

25% = 1/4 of 100
$16/4 = $4
$16-$4= $12
The item (the shirt in this case) was marked down
25%*16=4
so, subtract 4 from 16 to get the marked down price of $12.

he paid $12 because the original price was marked down.

Which statement best describes the relationship between the two cylinders shown below? (Use 3.14 for π.)



The volume of the cylinder on the left is greater.
The volume of the cylinder on the right is greater.
The volumes are equal.

Answers

answer:

the volumes of the cylindars are equal beacuse the right cylinder is simply squished down and made fat so the width and hight are flipped

hope this helped

-the chair with internet

The cylinder on the left, you can see that 4 ft is only halfway through the width, so :
4(2) * 7 *3.14 =
8*7 *3.14= 56
56*3.14 = 175.84
Answer for left cylinder: the volume of the left cylinder is 175.84.
Right cylinder:
7(2)*4*3.14=
14* 4 * 3.14 =
56 * 3.14 = 175.84
Answer for right cylinder: the volume of the right cylinder is 175.84, therefore, both of the cylinders volume is the same.

9. The two figures below have a scale factor of 3 : 2. What is the value of x?

Answers

C I think hope this helps

The value of x can be found by setting up a proportion based on the given scale factor of 3:2 is 16/3 units.

The breadth of the first parallelogram is 8 and the breadth of the second parallelogram is x.

Setting up the proportion, gives:

8/3 = x/2.

To solve for x,  cross-multiply:

[tex]8 \times 2 = 3 \times x.[/tex]

Simplifying the equation, gives:

16 = 3x.

Next, divide both sides of the equation by 3 to isolate x:

x = 16/3.

Therefore, the value of x is 16/3.

In which equation would you multiply both sides by 4.5 to get the variable alone?
A.6.1p = 4.5
B.p ÷ 6.1 = 4.5
C.p ÷ 4.5 = 6.1
D.4.5p = 6.1

Answers

The correct answer is actually C

If you multiply by both sides of the equation The 4.5 would cancel out on the left and you would be left with p=27.45

By applying the multiplication property, the equation you would multiply both sides by 4.5 to get the variable p alone is: C. p ÷ 4.5 = 6.1

Recall:

When applying the multiplication property of equality to find a variable, both sides of the equation will be multiplied by the same term/value.

Therefore, for the equation p ÷ 4.5 = 6.1, which is:

p/4.5 = 6.1

To get the variable p alone, multiply both sides by 4.5

Thus:

p/4.5 × 4.5 = 6.1 × 4.5

p = 27.45

Therefore, by applying the multiplication property, the equation you would multiply both sides by 4.5 to get the variable p alone is: C. p ÷ 4.5 = 6.1

11) slope and y-intercept, if the answer ignore this if you do know the answer than plz answer

Answers

Answer:

Slope : -1

Y-intercept : (0,6)

Step-by-step explanation:

Answer:

Slope: -1

y-intercept: 6

Step-by-step explanation:

Lets figure out the slope with the formula, [tex]\frac{y2 - y1}{x2-x1}[/tex]. Take 2 coordinates and substitute them in. Lets take (-3,9) and (-1,7). Here are the steps:

[tex]\frac{7-9}{-1-(-3)}[/tex]

[tex]\frac{-2}{-1+3}[/tex]

[tex]\frac{-2}{2}[/tex]

[tex]-1[/tex]

Now we know that the slope is -1, so m = -1.

Lets figure out the y-intercept. We have to have an equation with the slope in it. Since we don't know the y-intercept yet, we will use the equation y = -x + b. Lets take the coordinate (5,1). Substitute the coordinates in. Here are the steps:

1 = -5 + b

b = 6

Now we know that the y-intercept is 6, so b = 6. I hope this helped!

What is a proportional relationship?

It is defined as the relationship between two variables when the first variable increases, the second variable also increases according to the constant factor.

It is given that:

At a school carnival, tickets can be purchased to participate in different activities.

The data are shown in the picture.

From the data:

y ∝ x

Removing the proportional sign:

y = kx

Plug x = 8

y = 2

2 = 8k

k = 1/4

Thus, the value of the constant of proportionality that relates y, the total cost in dollars, to x, the number of tickets purchased is 1/4.

Between the 5 and the 7

Between the 7 and the 8

Between the 8 and the 0



Please help ill give brainlest

Answers

The dividend will be 457.80 and divisor will be 17.

The divisor is 1.7
The dividend is 45.78
We want 17 that is on the outside of the division symbol, written as a whole number.
45780 is on the inside of the division symbol.
So, to make 17 whole number, we will multiply it by 10. And we will also multiply 10 to 45.78 making it 457.80.
(multiplying with 10 means shifting decimal to one right place. Multiplying by 1000 means shifting decimal to 3 right places)
Hence, the dividend will be 457.80 and divisor will be 17.
