Answer:

The unit price per padlock is $2.80.

Step-by-step explanation:

This question can be solved as a simple rule of three problem.

We have that 9 padlocks cost $25.20. How much does 1 padlock cost? So:

9 padlocks - $25.20

1 padlock - $x

9x = 25.20

x = \frac{25.20}{9}

x = 2.80

The unit price per padlock is $2.80.

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
