Answer:
<u>$33.25</u>
Step-by-step explanation:
Taking Eric's hours as a ratio to the total hours :
- 3.5 : 3.5 + 2
- 3.5 : 5.5
- 3.5 x 2 = : 5.5 x 2
- 7 : 11
Multiply the ratio into the amount paid :
- 52.25 x 7/11
- 4.75 x 7
- <u>$33.25</u>
<u></u>
Eric's share of the money is <u>$33.25</u>
Try the app socratic or photomath!!
Two negatives make a positive so the question actually reads 0.22 + (5/8) = 0.22 + 0.625 = 0.845
therefore the answer is A because 0.845 is less than 1 (1/4 + 3/4 = 1)
P=2(L+W)
A=LW
given
P=62
62=2(L+W)
divide 2
31=L+W
minus W
L=31-W
sub into other one
A=LW
A=(31-W)(W)
228=31W-W^2
times -1
W^2-31W=-228
add 228 both sides
W^2-31W+228=0
factor
what 2 numbers multiply to get 228 and add to get -31
-19 and -12
(W-19)(W-12)=0
set to zero
W-19=0
W=19
W-12=0
W=12
sub back
L=31-W
L=31-12
L=19
or
L=31-19
L=12
the doorway is 12in by 19in
