It would be the angles 13*, 66*, 101* because they add up to be 180
The answer is 5.
17=(2x+2)+x
X is the length of the shorter piece and 2x+2 is two plus double the length of the shorter piece or X
X=5
Answer:
A=50.27
Step-by-step explanation:
Answer:
D. 8
Step-by-step explanation:
the upper quartile = 8
Let
x--------> volume of 50% fertilizer
y--------> volume of 30% fertilizer
we know that
x+y=160-----> x=160-y-----> equation 1
x*0.5+y*0.3=160*0.4-----> equation 2
substitute equation 1 in equation 2
[160-y]*0.5+0.3*y=63.8----> 77-0.35*y+0.25*y=63.8
0.10*y=13.2------> y=13.2/0.10----> y=132 gal
x=220-y----> x=220-132----> x=88 gal
the answer is
88 gal of 50% fertilizer
132 gal 30% fertilizer
