Answer:
19 cubic centimeters
Step-by-step explanation:
The equation for the volume of a sphere is 
.
We can setup the equation as 
.
Now we need to isolate the r^3. Divide both sides by 4/3 and pi, which leaves 
Now we take the cube root of both sides to have a single r on the right side. This comes out to equal 19 cm^3
Answer:
He would have $1,200 in his savings account by the end of the year
Step-by-step explanation:
12 months in a year x $100
12 x 100 = $1,200
Answer:
2x^4 + x^3 - 2x -1
Step-by-step explanation:
Do each one at a time and add them after you are done is necessary, first multiply 2x times x^3 this gives 2x^4. Then multiply 1 times x^3 to get x^3. Then multiply 2x times -1 to get -2x. Then multiply -1 and +1 to get -1. Then combine them together. None of the terms are like terms so you don't need to worry about combining them further but keep that in mind for other problems. The final answer becomes 2x^4 + X^3 - 2x -1 because none of the terms are the same power.
Coordinates of the center you can find from
x-3=0 and y+5=0
x=3 and y=-5
(3,-5) is the center of the circle.
25 is a square of the radius.
r²=25, so
r=5
Center (3,-5), r=5
So, the answer is D.
Answer:
5 2/3
Step-by-step explanation:
First add the whole numbers (3+2 = 5).
Then add the fractions. Since they already have common denominators, just add the numerators (1+1 = 2) and the denominator stays the same.
Since the numerator (top of the fraction) is smaller than the denominator (bottom of the fraction) and it can't be simplified, we are done. :-)
