Answer:
v= 141.37
Step-by-step explanation:
π · 3^2 · 15/ 3
=141.37167
3z+21=2
Subtract 21 from both sides
3z=0
Z=0
Answer:
72x² - 204x + 144
Step-by-step explanation:
When two linear functions are combined with addition and then by multiplication, quadratic equation is formed.This is an equation of one degree where it contains at least one term that is squared.
example, two linear functions can be;
(x+2)=0 and (x-3)=0
combining the two by multiplication will form
(x+2) (x-3) = x²-1x-6
x²-1x-6=0
Answer:
sorry,
yr question is incomplete.
Answer:
After 5 months, she will save the same amount using either option.
She would have saved $450 with either option.
Step-by-step explanation:
Set up expressions to represent the amount of money saved for each saving option, where x is the number of months
The first one can be represented by 30x + 300
The second one can be represented by 50x + 200
Set these equal to each other and solve for x:
30x + 300 = 50x + 200
300 = 20x + 200
100 = 20x
5 = x
So, after 5 months, Tina will save the same amount of money with both options.
To find how much she will save, plug in 5 as x into either expression:
30x + 300
30(5) + 300
150 + 300
= 450
So, she would have saved $450 with either option.
