5.20/4.16=1.25
5.20 is apples
4.16 is $
1.25 is $ per pound
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:
63%
Step-by-step explanation:
12/19=0.63157895
0.63157895*100=63.1578947
Answer:
See below
Step-by-step explanation:
Remember SOHCAHTOA
Soh...
Sine = Opposite / Hypotenuse
...cah...
Cosine = Adjacent / Hypotenuse
...toa
Tangent = Opposite / Adjacent
In this case we use TOA.
tan(71) = x/34
x = tan(71) * 34
x = 98.7
The answer to your question is B
