Three numbers are in the ratio 5 :3 : 2. If the sum of their squares is 5472, find the three numbers

jasenka [17]

Answer:

60 36 24

Step-by-step explanation:

5 3 2

25x +9x + 4x = 5472

38x = 5472

x = 144

25(144) = 3,600 9(144) = 1,296 4(144) = 576

60² = 3,600 36²= 1,296 24² = 576

3,600 + 1,296+576 = 5,472

A plane flies from Springville to Brockton and then back to Springville. When there is no wind, the round trip takes 6 hours and

ch4aika [34]

Answer:

Step-by-step explanation:

Let x represent the speed of the plane in still air.

When there is no wind, the round trip takes 6 hours and 24 minutes. Converting to hours, it becomes

6 + 24/60 = 6 + 0.4 = 6.4 hours

Distance = speed × time

Distance of the round trip = 6.4x

But when there is a wind blowing from Springville to Brockton at 50 miles per hour, the trip takes 6 hours and 40 minutes. Converting 6 hours and 40 minutes, it becomes

6 + 40/60 = 6 2/3 = 20/3 hours

The total speed would be

(x - 50)miles per hour

Distance covered = 20/3(x - 50)

Therefore, since both round trips are the same distance, then,

6.4x = 20/3(x - 50)

Cross multiplying by 3, it becomes

19.2x = 20(x - 50)

19.2x = 20x - 1000

20x - 19.2x = 1000

0.8x = 1000

x = 1000/0.8 = 1250 mph

Distance covered on the round trip is

6.4x = 6 × 1250 = 7500 miles

Therefore, the distance from Springville to Brockton is

7500/2 = 3750 miles
