Answer:
Step-by-step explanation:
Area of circle = πr² = 15 m²
Volume of Cylinder = πr²h
= 15 * 3
= 45 m³
Volume of Cone = (1/3)πr²h
= 15 m³
When given a proportion, you can solve for a variable by cross multiplying.
Take the numerator of the first fraction and multiply it by the denominator of the second fraction, then set the product equal to the denominator of the first fraction times the numerator of the second.
12*3 = 5x
To solve for x divide both sides by 5
x = 36 / 5
x = 7.2
Answer:
The first step is to determine how many times 2x goes into 8x^3
Step-by-step explanation:
The first step is to determine how many times 2x goes into 8x^3
4x^2
--------------------------
2x-1 | (8x3 – x2 + 6x + 7
8x^3 -4x^2
Answer:
a = 4
Step-by-step explanation:
first, you are supposed to subtract both sides by 6 so you will get:
<u>6 - 4a = -10</u>
-6 -6
-4a = -16
Then, you divide both sides by -4 to cancel out the -4 before the "a"
<u>-4a</u> = <u>-16</u>
-4 -4
Last, you will get a = 4 and that is your answer because when you divide a negative number by another negative number, you will get a positive number.
