3: multiply the change per minute by how many minutes: 3.1x15=46.5. 5: Is your opinion, I can't tell you how to feel. But a negative times a negative is a positive, so if there is an even number of negatives no matter how many positives there are it will be positive, if there is an odd number of negatives it will be negative. :) Hope this helps!

prism M and pyramid n have the same base area and the same height. cylinder p and prism Q have the same height and the same base
Katen [24]

Answer:

The volume of cone z has the same base area as cylinder y but its height is 3 times the height of cylinder y have the same volume.

Step-by-step explanation:

The volume of a cylinder having base area 'A' and height 'H' is given by  V = AH, and the volume of a cone having the same base area as the cylinder i.e. A and height 3 times the height of the cylinder i.e. 3H is given by V' = \frac{1}{3} A(3H) = AH.

So, V = V'

Hence, the volume of cone z has the same base area as cylinder y but its height is 3 times the height of cylinder y have the same volume. (Answer)

As a student, you are able to earn extra money by assisting your neighbors with odd jobs. If you charged $10.25 an hour for your
malfutka [58]

Answer:

822 hours

Step-by-step explanation:

Let's say that you work for h hours. Then since each hour, you charge $10.25, then your total earnings after h hours will be:

10.25 + 10.25 + 10.25 + ... + 10.25, where you add 10.25 to itself h times.

Adding a number n to itself x times is the same as multiplying that number n by x: nx. It's the same thing here: we multiply 10.25 by h because we added 10.25 to itself h times:

10.25 * h

Now, we do know that the actual total amount of money you earn is $8425, so we can just set this value equal to our above expression:

10.25 * h = 8425

Divide both sides by 10.25 to solve for h:

h = 8425/10.25 ≈ 821.95 ≈ 822 hours

Hope this helps!

Yes it is possible to prove this figure is a parallelogram

Refer to the attached image

Step 1) mark the corner points as A, B, C, D

Step 2) Draw a diagonal from A to C (shown in red)

Step 3) Through the SSS (side side side) property, we can prove the two triangles ABC and ADB are congruent

Step 4) By CPCTC (corresponding parts of congruent triangles are congruent), we can say the angles of the triangles are congruent as well. So angle ACB is congruent to angle CAD (as shown in green)

Step 5) Through the converse of the alternate interior angle theorem, this means that the BC is parallel to AD

------------------------------------

If you repeat those steps, but instead of drawing diagonal AC you draw diagonal BD, then you can prove that AB || CD

Once you know that AB || CD and BC || AD, then you have proven the figure is a parallelogram. By definition, a parallelogram is a four-sided figure with opposite sides that are parallel.
