Answer: 300

Step-by-step explanation:

Let the number be represented by x.

Therefore, based on the information given in the question, this can be expressed as:

36% of x = 108

36/100 × x = 108

0.36 × x = 108

0.36x = 108

x = 108/0.36

x = 300

Therefore, the number is 300

A painting is 2 in tall and 3 in wide. If it is enlarged to a width of 15 in then how tall will it be?
vekshin1

Answer:

10 in

Step-by-step explanation:

Old proportions:

2 x 3

New proportions

h x 15

Assuming the painting has been increased by a constant scale factor.

Where x is the unknown scale factor, and h is the height after it has been enlarged.

3 * x = 15\\2 * x = h

Rearrange second equation:

3 * x = 15\\x =\frac{h}{2}

Substitute:

3*\frac{h}{2} =15\\\frac{h}{2}=5\\h=10
