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.

13. Find the value of x.<br> 140°<br> 136°<br> х<br> 148°<br> 142°<br> 150°
garik1379 [7]

Answer:

sum of interior angle of heptagon is 900°.

140°+148°+136°+150°+142°+90°+x=900°

806+x=900°

x=900°-806°

x=94°

Two buses leave a station at the same time and travel in opposite directions. One bus travels 15 /kmh faster than the other. If
Nat2105 [25]
Since the buses travel in opposite directions, the speed at which they distance themselves is the sum of their speeds.
One bus travels at speed s.
The other bus travels at speed s + 15.
The sum of the speeds is s + s + 15 = 2s + 15

speed = distance/time

distance = speed * time

366 = (2s + 15) * 2

183 = 2s + 15

168 = 2s

s = 84

The slower bus travels at 84 km/h.

s + 15 = 84 + 15 = 99

The faster bus travels at 99 km/h.

Check:
In 2 hours, the slower bus travels 2 * 84 km = 168 km
In 2 hours, the faster bus travels 2 * 99 km = 198 km
In 2 hours, the buses are 198 km + 168 km = 366 km apart.
Our answer is correct.
