V=hpir^2
r=10
v=6283
6283=hpi10^2
6283=100hpi
divide both sides by 100
62.83=hpi
aprox pi=3.141592
divide both sides by pi
19.9994143=h
so about 20 inches
Answer:
x = 5, x = 
Step-by-step explanation:
Given
+ 
= 3 
= 
=
= ( cross- multiply )
10(x² - 6x + 8) = 3(2x² - 10x + 10) ← distribute both sides
10x² - 60x + 80 = 6x² - 30x + 30 ← subtract 6x² - 30x + 30 from both sides
4x² - 30x + 50 = 0 ( divide through by 2 )
2x² - 15x + 25 = 0 ← in standard form
(2x - 5)(x - 5) = 0 ← in factored form
Equate each factor to zero and solve for x
2x - 5 = 0 ⇒ 2x = 5 ⇒ x =
x - 5 = 0 ⇒ x = 5
Answer:
A has 77 grams and B has 12 grams.
Step-by-step explanation:
In order to find the amount of fat in both, we need to set up two equations in standard form. First, we can set up one comparing the two amounts and solve for the constant.
A = 6B + 5
A - 6B = 5
Now we can create one using the difference of the two.
A - B = 65
To solve, we now multiply the second equation by -1 and solve for B.
A - 6B = 5
-A + B = -65
----------------
-5B = -60
B = 12
Knowing this we can plug into the equation and find the value of A.
A - B = 65
A - 12 = 65
A = 77
Answer:
D
Step-by-step explanation:
The solution to a systems of equations is the intersection point of the lines. If no solution is possible then their is no intersection point. The lines must be parallel.
If Louie bought new tools for $100 dallors and they each cost $10 then he would have bought 10 tools because 100\10 =10
