Answer:

a) 1/7 liters of petrol is used for each mile

Step-by-step explanation:

Justin fills his car with 40 litres of petrol. After travelling 35 miles it's down to 35 litres.

From the above statement:.

The difference is :

40 litres - 35 liters = 5 liters

Hence:

After travelling 35 miles he used 5 liters

(a) How much petrol does the car use each mile?

This is calculated as:

35 miles = 5 Liters

1 mile = x liters

Cross Multiply

35x = 5 Liters

x = 5/35

x = 1/7 liters

Hence, for each mile, 1/7 liters of petrol is used

Tems11 [23]

Answer:

120 ft

Step-by-step explanation:

First, you should decipher how many minutes have passed by 10:57-11:05 AM. When you count up to 11:05 AM starting from 10:57 AM, you should get 8, meaning 8 minutes have passed by.

After that, you should multiply the minutes by how many feet Shana can dive per minute. 15 (feet per minute) multiplied by 8 (minutes) equals 120.

In 8 minutes her depth will 120 ft.

Destiny works on commission as an office supply saleswoman. She sold a computer that cost $700 and received a $126 commission.
chubhunter [2.5K]
Hello,

If you want to find the percentage of anything, simply divide how much of the total number by the total number. 126 ÷ 700, which is 0.18.

To turn the decimal into a percentage, simply move the decimal place two places to the right, and it is now 18%.

In conclusion, she earned 18% of her sale.
Hope this helps! =)

Find the height "h" so that its area is equal to 400 square cm.
jenyasd209 [6]

Answer:

h = 20 cm

Step-by-step explanation:

The area of a trapezoid is given by

A = 1/2 (b1+b2) *h

where b1 and b2 are the two bases

We are given a =400 and b1 =27 and b2 =13

400 = 1/2 (27+13) *h

400 = 1/2 (40) *h

400 = 20h

Divide each side by 20

400/20 = 20h/20

20 =h
