For the answer to the question above, this question is incomplete. I've answered this question before.
Is it like this?
V = (1/3) * (area of the base) * height
<span>If you have a pyramid with a square base, you just multiply the length of both sides together. For example, if the pyramid was 9 inches on a side, the area of the base is 9 * 9 = 81 sq. inches. </span>
<span>Then you multiply that by the height and finally take 1/3 of the result. For example, if the pyramid was 10 inches high, you multiply 81 sq. inches x 10 inches = 810 cubic inches. But you have to remember to take a third of that result. 810 cubic inches / 3 = 270 cubic inches.
</span>I hope this helps
Answer:
All of your choices are correct.
Step-by-step explanation:
4.50 ÷ 18 = .25 each
.25 x 4 = 1.00
.25 x 36 = 9.00
12 x .25 = 3.00

Step-by-step explanation:
<u>Sinusoid</u>
The shape of a sinusoid is well-know because it describes a curve with a smooth and periodic oscillation. The sine and cosine are the two trigonometric functions in which the graph matches the description of a sinusoid. The sine can be identified because its value is zero at time zero.
The graph shown in the figure corresponds to a sine. The other characteristics of the sine function are
* It completes a cycle in
radians
* It has a maximum of 1 and a minimum of -1
* It's increasing for a quarter of the cycle, decreasing for half of the cycle, and increasing for the remaining quarter of the cycle
* The equation is
The function starts decreasing for the first quarter, which only is possible if the amplitude A is negative. We can also see the maximum and minimum values are 2 and -2 respectively. This means the amplitude is A=-2
We can also see the function completes 3 cycles in 
radians or 6 cycles in radians. Or, equivalently
Thus, the function can be expressed as
For numbers 9 and 10, we are dealing with negative exponents.
The rule of exponents states that any quantity b, taken to the power -n, equals the reciprocal of b, taken to the nth power.
Example: x⁻³ = 1 / x³
Number 9: ( 3 / y² ) ⁻³
Step 1: take the reciprocal:
( 3 / y² ) ⁻³ = ( y² / 3 ) ³
Step 2: distribute the exponent
( y² / 3 ) ³ = y⁶ / 27
Try to do number 10 on your own. If you have any questions, comment.
12 songs. 25% of 12 is 3, so you add 3 to 12 and get 15. You then find that 20% of 15 is 3 so you subtract 3 from 15 and get 12 again.
