The answer is 15, to find this take 225 and square root
The area of a square is length times length( or side times side) . 15 times 15 is 225
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
Answer:
Angles that are congruent and have the same value
Step-by-step explanation:
The answer is B.
The commutative property enables you to switch around the numbers in addition or multiplication. B does this correctly and simplifies the answer correctly, giving you 1,800.
