If you continue the line of the second step (from the top), you will get a parallel to the floor which will also equal to 4 feet.

Now the right triangle just created has one leg = 4 feet and another = 3 feet.
Calculate the hypotenuse (Railing) using Pythagoras;

(Railing)² = 4² + 3²
((Railing)² = 4² + 3²
Railing)² = 16 + 9 =25
(Railing)² = 25 and Railing = √25 = 5

Jen picked three fourth in half an hour if she keeps the same rate how many will she pick in 2 hours

Sunny_sXe [5.5K]

Alright, lets get started.

Jen picked three fourth in half an hour.

Half an hour means 30 minutes.

At the same rate, how many she can pick in 2 hours.

2 hours means $2 * 60 = 120$ minutes

Now,

In 30minutes, Jen can pick = $\frac{3}{4}$

In 1 minute, Jen can pick = $\frac{3}{4} *\frac{1}{30}$

In 120 minutes, Jen can pick = $\frac{3}{4} *\frac{1}{30} * 120 = 3$

Hence Jen can pick complete 3 in 2 hours of time.

So the answer is 3 : Answer

Hope it will help :)

Steve washed 15 cars in 3 hours.how many cars can he wash in 7 hours?

DanielleElmas [232]

35 Cars because, if you times 3 by 5 it equals 15 which means that 1 hour equals 5 cars. So you times 7 by 5 and that will give you the amount of cars that were washed.
