Your Teacher Ask You To Divide 160 Meter Rope Into 3 Pieces In The Ratio Of 7:8::9. What Will Be The Length Of Each Rope.

Your teacher ask you to divide 160 meter rope into 3 pieces in the ratio of 7:8::9. What will be the length of each rope.

 

Answer:

smallest rope = 140/ 3 meters

longer rope = 160/ 3 meters

longest rope = 60 meters

Step-by-step explanation:

Given: ratio of 7:8::9

            160 meter rope

Ask: What will be the length of each rope?

Solution:

7x + 8x + 9x = 160 (combine like terms)

24x = 160

24x = 160

  24      24

x = 20/3

Substitute the value of x for 7x, 8x and 9x respectively to get the length of each rope.

For 7x,

=7(20/3)

= 140/3 meters

For 8x,

=8(20/3)

=160/3 meters

For 9x,

=9(20/3)

=60 meters

A Truck Whose Bed Is 8 Feet Long, 5 Feet Wide, And 3 Feet High Is Delivering Sand In A Construction Site. How Many Trips Must The Truck Make To Delive

A truck whose bed is 8 feet long, 5 feet wide, and 3 feet high is delivering sand in a construction site. How many trips must the truck make to deliver 300 cubic feet of sand?   Answer: no. of trips = 3 Step-by-step explanation: A truck whose bed is 8 feet long, 5 feet wide, and 3 feet high is delivering sand in a construction site. How many trips must the truck make to deliver 300 cubic feet of sand? Given: length (l) = 8 ft            width (w) = 5 ft            height (h) = 3 ft            volume of sand to be delivered (Vs) = 300 cubic ft. Required: number of trips for the truck to meet the required volume of sand Solution: Vt (volume of bed of truck) = l × w × h = (8 ft) ( 5 ft) (3 ft) = 120 cubic ft. no. of trips = volume of sand / volume of bed of truck = 300/ 120 = 2.5 there is no half trip so we should round round it up no. of trips = 3
