Answer:
r = 4.908
Step-by-step explanation:
V = 885
height (given in the picture) = 11.7
V =
h
V = (3.14)(
)(h)
885 = (3.14)(
)(11.7)
885/3.14/11.7 = 
Take the square root and you get 4.908.
for z the fraction value is 1/26 and for other letters then Z is 25/26
Answer:
Its a i just took the test
Step-by-step explanation:
They will have the same amount of money after 7 weeks.
We first set these equal to each other:
36+4x=x²+15
We want to gather all of the variables on one side. Subtract 4x from both sides:
36+4x-4x=x²+15-4x
36=x²-4x+15
We want the equation to be equal to 0 to solve it, so subtract 36 from both sides:
36-36=x²-4x+15-36
0=x²-4x-21
We can factor this expression. We want factors of -21 that sum to -4; -7(3)=-21 and -7+3=-4:
0=(x-7)(x+3)
Using the zero product property, we know that x-7=0 or x+3=0; this means x=7 or x=-3. Since a negative number of weeks makes no sense, the answer is 7 weeks.
