Answer:

First we need to set a proportion

Currently the negative measures 15 inches by 2 inches. And the longer dimension of the printed version is 4 inches. Therefore:

$\frac{2}{y} = \frac{15}{4}$

$15y = 8$

$y = 0.5333$

Therefore, the dimension of the shorter dimension is 0.5333.

Answer:

Below

Step-by-step explanation:

To find surface area, you can just find the area of each side and add them up!

11 ft x 9 ft x 2 = 198 ft^2 (this is the surface area of the front and back)

12 ft x 9 ft x 2 = 216 ft^2 (this is the surface area of the sides)

12 ft x 11 ft x 2 = 264 ft^2 (this is the surface area of the top and bottom)

Surface area = 198 + 216 + 264

= 678 ft^2

Hope this helps! Best of luck <3

Olenka [21]

Answer:

=4s+10t

Step-by-step explanation:

4s has no like terms so we divide by 10 and that gives us 4.

100t has no like terms so we divide 100 by 10 that gives us 10. This means that our total answer is (4s+10t). Hope this helped! If it did can I have brainliest thx.

Answer:

The complete table will be:

x y

1 5

0.8 4

0.4 2

Step-by-step explanation:

Given rule is:

y = 5x

In the given rule, x is multiplied by 5 to get the values of y. The same rule can be manipulated to find the value of x in terms of y.

$\frac{y}{5} = \frac{5x}{5}\\x = \frac{y}{5}$

Putting y = 5

$x = \frac{y}{5}\\x = \frac{5}{5}\\x = 1$

Putting y = 4

$x = \frac{y}{5}\\x = \frac{4}{5}\\x = 0.8$

Putting y = 2

$x = \frac{2}{5}\\x = 0.4$

Hence,

The complete table will be:

x y

1 5

0.8 4

0.4 2
