10) what is the percent change
from 15 to 18?

20%

Step-by-step explanation: Since the number changes from 15 to 18, it's getting bigger which means it increases. To find the percent increase, we use the formula shown.

The amount of change is the difference between the two numbers. In this case, we would subtract 18 - 15 which equals 3. Then, we put 3 over our original number which is 15.

3 ÷ 15 = 0.2

Now, we need the percent increase which means we need to write 0.2 as a percent by moving the decimal point two places to the right to get 20%.

Therefore, the percent increase is 20%

a kite and rhombus have the same shape. as we don't have any specific formula for the calculation of area of kite. the diagonals are used to calculate the area of a kite or rhombus.

the formula for area of rhombus is given by:

here, d_1 is the first diagonal and d_2 is the second diagonal.

so,
