Answer:

Unit rate = 20.8 ft/s

Step-by-step explanation:

We are given rate for 644.8 ft in 31 s

We need to find unit rate. We will calculate how many feet move in 1 second.

When rates are expressed as a quantity of single unit.

Such as 2 feet per second (It means in 1 seconds move 2 feet)

5 miles per hour ( In 1 hour move 5 miles)

We will calculate in 1 second how much feet.

In 31 seconds = 644.8 ft

In 1 second = 644.8÷31

Unit rate = 20.8 ft/s

A delivery company has 18 vehicles in its fleet.
Ilia_Sergeevich [38]

Answer: £1517.04

Step-by-step explanation:

The fuel expenses for the vans will be calculated as:

Vans:

Since the average distance travelled per day is 198km and the average distance travelled per litre is 9km, the van would use:

= 198/9

= 22 litres

Since there are 8 vans, they'll use:

= 22 × 8 = 176 liters

Trucks:

Since the average distance travelled per day is 620km and the average distance travelled per litre is 6.2km, the truck would use:

= 620/6.2

= 100

Since there are 10 trucks, they'll use:

= 100 × 10 = 1000 liters

The amount of liters for both the van and the truck will be:

= 176 liters + 1000 liters

= 1176 liters

The fuel cost will then be:

= 1176 × 1£1.29

= £1517.04

Which of the following equations are equivalent to-2m-5m-8 #-(-7) + m?D-15m-4md:7m-8-rn-4□-3m-8-4-m□m-4.7m-8-8.7m- 4-m□-8.3m-4-m
Readme [11.4K]
-2m - 5m - 8 = 3 + (-7) + m
-7m - 8 = 3 - 7 + m
-7m - 8 = m - 4 <=== here is one

m - 4 = -7m - 8 <=== another one
-8 - 7m = -4 + m <== and another one
