Find the rate at which you work, that is, the # of walls painted per hour:
13 1/3 walls 40/3
------------------ = ---------- wall per hour
14 1/4 hr 57/4
Keep 40/3 as it is; invert the divisor (57/4) and then multiply the result by 40/3:
40 4 160 wall
------ * ------ = --------------- = approx. 0.94 wall in one hour, or 160/171 wall / hr
3 57 171 hr
Answer:
1/3(3j+6)= j+2

Hope this helps
First, let's put all of the variables together.
4m + 5m + 5 + 40 = 180.
Add them.
M is the same multiplier, so we can add 4 and 5 together to make 9m.
Add 5 and 40.
9m + 45 = 180.
From here, we can go two ways. I will show the first way, which is my personal preference.
We want to get rid of the coefficient on m to isolate it, so we must divide it by its coefficient. The coefficient on m is 9. So, divide m by 9. We must also divide everything else by 9.
9m/9 = 1m
45/9 = 5
180/9 = 20
Plug it in--
m + 5 = 20.
Subtract the 5 from both sides to isolate m.
m = 15.
Answer:
answer for a,b and c are all zero (0).
reasons for all:
zero(0) divided by any number is zero(0).
To evaluate the radius of the cone we proceed as follows:
V=1/3 πr²h
plugging in the values, v=88π, h=8 ft
step 1
88π1/3πr²(8)
step 2
88π=8/3πr²
step 3
divide both sides by π
88=8/3r²
multiply both sides by 3/(8)
88(3/8)=r²
step 4
simplify
33=r²
step 5
get the square root
r=√33
Thus the mistake that Fatima made was:
<span> In step 3, Fatima did not multiply 88 by the reciprocal of 8/3 </span>
