What do you want to find out? > The rate at which Bill puts shringles on a rood. What do you know? > Bill and Chip each fi

denis23 [38]

Answer:

(a) b = (4/7)c

(b) Bill: 40 shingles/hour; Chip: 70 shingles/hour

Step-by-step explanation:

Let b and c represent Bill's and Chip's rates in shingles per hour, respectively. Then we have ...

7b = 4c

c - b = 30 . . . . shingles per hour difference in rates

(a) Bill's rate in terms of Chip's rate can be found by dividing the first equation by 7

b = (4/7)c . . . . . Bill's rate is 4/7 of Chip's rate

(b) To find the rates, we can multiply the second equation by 7 and substitute using the first equation:

7c -7b = 210

7c -4c = 210

c = 210/3 = 70

b = (4/7)(70) = 40

Bill's rate is 40 shingles per hour; Chip's rate is 70 shingles per hour.

Hello! Please ignore the stuff I already wrote, can someone help me find x and y?

DanielleElmas [232]

Answer:

x=12

y= $12\sqrt{3}$

Step-by-step explanation:

Hey There!

to solve this problem we need to use the 30 - 60 - 90 triangle rule

So you are correct on x because the hypotenuse is 2x

24/2=12

y would equal $12\sqrt{3}$

as you could see in the image down below
