Answer:
12
Step-by-step explanation:
The 6 part of the ratio represents 36 tomatoes.
Divide 36 by 6 to find the value of one part of the ratio
36 ÷ 6 = 6 ← value of 1 part of the ratio, thus
number of bananas = 2 × 6 = 12
So, this is a question that strictly relates to physics.
1st: multiply the average displacement by the number of people.
2nd: Divide this number by 80x40m^2 which will find the height .
In case you want more detail, please rate it well and send a message to me. I will calculate it for you.
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
