Question

A truck is carrying 8 cars weighing an average of 4,500 pounds each.What is the total weight in tons the cars on the truck?

Ben's living room is a rectangle measuring 10 yards by 168 inches. By how many feet does the length of the room exceed the width?

Answer 1

4500(8)=36000 pounds in total
Each car weighs 4500 pounds. There are 8 cars in total.

168/12=14 feet

3 feet in 1 yard
30 feet

30-14=16 feet

Answer 2

Answer: The total weight in tons the cars on the truck= 18 tons.

The length of the room exceed the width by 16 feet.

Explanation:

a) Given: Weight of 1 truck=4500 pounds

Thus, weight of 8 trucks=
`8*4500` pounds

`=36000\ pounds`

We know that 1 ton=2000 pounds

Thus, weight of 8 trucks in tons=
`(36000)/(2000)=18\ tons`

Hence, the total weight in tons the cars on the truck= 18 tons.

b) Given: Dimensions of the room are as

Length=10 yards and width= 168 inches

We know that 1 yard=3 feet and 1 inch=
`(1)/(12)\ foot`

Thus, length
`=10*3=30\ feet`

width=
`168*(1)/(12)=14\ feet`

The difference between length and width=
`length-width=30-14=16\ feet`

Hence, the length of the room exceed the width by 16 feet.
