Pythagorean theorem:
a^2+b^2=c^2 (C^2 always is the hypotenuse)
21^2+b^2=29^2
441+b^2=841
841-441=400
square root of 400 is 20
Your answer is 20
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
Answer:
$67,580.73
Step-by-step explanation:
$49,329÷100=$493.29 (1%)
$493.29×37=$18,251.73 (37%)
$49,329+$18,251.73=$67,580.73
All we have to do is multiply them by each other accept we change the percent into a decimal.
65% = 0.65
soooo
0.65 x 65 = 42.25
<span>answer? =42.25
</span>i hope this was helps:)
and don't forget 2
<span>MARK ME BRAINLIEST! :D</span>
