The rectangle's length is 30 inches while it's width is 24 inches.

Step-by-step explanation:

Step 1; Any rectangle's area is calculated by multiplying the rectangle's length and its width. Assume the the rectangle's length is 5x while it's width is 4x as it is given that the ratio of it's length to width is 5: 4.

Area of the rectangle = 5x × 4x = 720, 20x² = 720.

x² = $\frac{720}{20}$ = 36, x =√36 = 6.

Step 2; As we assumed length equals 5x and the width will equal 4x.

The rectangle's length = 5x = 5 × 6 = 30 inches,

The rectangle's width = 4x = 4 × 6 = 24 inches.

Trina is purchasing a new bike the store is having 20% off sale and she as 10% coupon of the sale price if the original price of

marusya05 [52]

20% of 89.75 is 17.95
$\frac{20}{100} = \frac{x}{89.75} \\ x = \frac{89.75 \times 20}{100} = \frac{1795}{100} = 17.95$
so :
$89.75 - 19.95 = 71.8$
the Trina's coupon will subtract the answer by 10%:

10%of 71.8 is 7.18
$\frac{10}{100} = \frac{x}{71.8} \\ x = \frac{71.8 \times 10}{100} = \frac{718}{100} = 7.18$
so the final answer is:
$71.8 - 7.18 = 64.62$
she has to pay $64.62
hope this helps

Margarita [4]

-4 isn't a real number because there is no square root of -4. However, there is a cube root of -8, because -2 * -2 * -2 = -8.
