Question

Pleaseee help with 22 & 23 !! ASAP !!

Answer 1

#22. We are given that y = 1/4. So, we want to plug this value into the expression 15/y:

15/(1/4)

When you divide by a fraction, you should follow the rule “flip the guy and multiply”. Basically, 15/(1/4) = 15 * 4 = 60.

The answer for #22 is (D).

#23. We can use a proportion:

(The shaded area)/(entire circle area) = (360 - 60)/360

But, we don’t have to find the areas of the region and circle; we can just solve the fraction:

(360 - 60)/360 = 300/360 = 30/36 = 5/6

The answer for #23 is (A).

Answer 2

Hey!

22) If y =
`(1)/(4)` then
`(15)/(y) = 15 / (1)/(4)`

To divide fractions, you have to keep, change, flip.

`Keep\ (15)/(1) \\ Change\ / to * \\ Flip (1)/(4) = (4)/(1)`

It becomes:
`(15)/(1) * (4)/(1) = (60)/(1) \rightarrow 60`

22. D)60

23) Circles measure 360°. 50° is left. Subtract 50 from 360 and make a fraction, using the difference as a numerator, and 360 as the denominator.

`360 - 60 = 300`

The fraction becomes:

`(300 / 30)/(360 / 30) = (10 / 2)/(12 / 2) = (5)/(6)`

23) A.
`\bf(5)/(6)`

Good luck and hope this helps! :)
