Jenna can type 140 words in 4 minutes. If she needs to type 385 words, how long would this take her? Explain how you got your answer

11 minutes

Step-by-step explanation:

Because she types only 140 words in 4 minutes so if you add

140+140=280

if you divide

140/4 you get 35

so every minute she types in 35 words. So multiply

11 times 35 and you exactly get 385.

answer is  

c.

36

step-by-step explanation:

yx = 36

step-by-step explanation:

cos f = opposite side/ hypotenuse

cos f = yw / yx

we know cos f = 4/9 and yw =16

4/9 = 16/yx

multiply each side by yx

4/9 yx = 16/ yx * yx

4/9 yx = 16

multiply each side by 9/4

9/4 * 4/9 yx = 16 *9/4

yx = 36
