A car cost $18,000, which is 9/10 of the cost of an apartment. A motorcycle cost 1/5 of the cost of the apartment or 4/5 of the
blagie [28]

Answer:

$1500

Step-by-step explanation:

let the cost of the apartment = x

Hence the cost of the car is \frac{9}{10} \times x

also given the cost of car=18000

Hence

18000= \frac{9x}{10}

x= \frac{18000 \times 10}{9}

x= 2000 \times 10

x= 20000

Motorcylce cost = \frac{1}{5} of Cost of apartment

= \frac{1}{5} \times 20000

= 4000

Also Motorcylce cost=\frac{4}{5} of the cost of 100 soccer balls.

Hence

4000= \frac{4}{5} x (cost of 100 soccer balls.)

(cost of 100 soccer balls.)= \frac{4000 \times 5}{4}

(cost of 100 soccer balls.)= 1000 \times 5

cost of 100 soccer balls= 5000

cost of 1 soccer balls = \frac{5000}{100}

cost of 1 soccer balls = 50

cost of 30 soccer balls = 50 x 30

cost of 30 soccer balls = 1500

Hence the cost of 30 balls is $1500

area of base  =  pi * radius2  =  pi * (10/2)2  =  pi * 52  =  25pi   cm2

volume  =  (1/3)( 25pi )( 9 )   cm3

volume  =  75pi   cm3

volume  ≈  236  cm3

A helicopter leaves Rogers airport and flies north at 180 mph. One hour later a plane leaves the airport and follows the helicop
Dmitrij [34]
Distance = speed * time

The plane catches the helicopter when they both traveled the same distance, d.
The helicopter traveled t hours, but the plane traveled 1 hour less, or t - 1 hours.

helicopter:
d = 180t

plane:
d = 330(t - 1)

The distance they both traveled, d, is the same, so

180t = 330(t - 1)

180t = 330t - 330

-150t = -330

t = (-330)/(-150)

t = 2.2

The helicopter traveled 2.2 hours, so the plane traveled 1.2 hours.

Answer: The plane catches the helicopter after 1.2 hours of plane flight.
