Answer:
37.5
Step-by-step explanation:
so x% of 40 is 15
the equation for that is
x/100 * 40 = 15
40x/100 = 15
multiply 100 on both sides
40x = 1500
divide 40 on both sides
37.5
37.5% of 40 is 15
The formula for volume of a sphere is V=4/3πr^3.
If we substitute 18 in for "r", we can work the problem out from there.
V = 4/3(3.14)(18)^3
V = 24,416.64 cubic units, so your answer will be C.
Hope that helps!
Answer:
x=2 or x=3
Step-by-step explanation:
x^4 - 5x^3 + 7x^2 - 5x + 6 = 0
Step 1=Factor left side of equation.
(x-2) (x-3) (x^2 + 1) = 0
Step 2=Set factors equal to 0.
x-2 = 0 or x-3 = 0 or x^2 + 1 = 0.
Answer:x=2 or x=3
um is this all one equation?
like -2.2×(-2)÷(-14)×5-2.2×(-2)÷(-41)×5?
