Elle placed a bucket under a leaky roof. The bucket was 3/10 full after 2/5 of an hour. How much water is leaking per hour. 1. 3/5 bucket per hour

2. 1 bucket per 1 1/4 hour

3. 1 1/2 buckets per hour

4. 3/4 bucket per hour

4. 3/4 bucket per hour

Step-by-step explanation:

The bucket was 3/10 full after 2/5 of an hour.

How much water is leaking per hour.

Quantity of water leaking per hour = 3/10 ÷ 2/5

= 3/10 × 5/2

= 15/20

= 3/4

Quantity of water leaking per hour = 3/4 bucket per hour

The answer is

4. 3/4 bucket per hour

Check:

3/4 × 2/5

= 6/20

= 3/10

hope this !

step-by-step explanation:

d = distance between moon and sun, which in this problem is the hypotenuse of a right triangle.  

the distance y is the side opposite to angle x in the right triangle.   use the definition of the sine function from basic trigonometry.

sin(x) = y/d ⇒

d = y/sin(x)

answer: -1
