How will the volume of the pyramid change if each side is multiplied by a factor of 5?​
o-na [289]

The volume of the pyramid is changed by a factor of 125

<u>Solution:</u>

Given that, each side of a pyramid is multiplied by a factor of 5.

We have to find how will the volume of the pyramid changes?

Now, we know that, volume of a pyramid =\frac{\text {length} \times \text { breadth } \times \text {height}}{3}

Now, each dimension is multiplied by factor of 5.

Then, volume of new pyramid =\frac{(5 \times l e n g t h) \times(5 \times \text { breadth) } \times(5 \times \text { height })}{3}

=5 \times 5 \times 5 \times \frac{\text { length } \times \text {breadth\timesheight}}{3}

Volume of new pyramid = 125 \times volume of old pyramid.

Hence, the volume of the pyramid is changed by a factor of 125.

URGENT HELP<br> Solve for X
suter [353]

Answer:

x = 3

Step-by-step explanation:

95 + 85 + 100 + 27x -1 = 360

280 + 27x - 1 = 360

279 + 27x = 360

27x = 81

x = 3

Double check your work:

95 + 85 + 100 + 27(3) - 1 = 360

95 + 85 + 100 + 81 -1 =360

360 = 360

Sharvay spends $15 to buy 17 pieces of candy. M&amp;M’s cost $0.75 and candy bars cost $1. How many M&amp;M’s and candy bars did
Zinaida [17]

Answer:

8 M&Ms and 9 Candy Bars

Step-by-step explanation:

$15 dollars could buy 15 candy bars, and there are 17 pieces of candy total.

Prioritizing the number of bars:

0.75 * 2 = 1.50

1.50 * 2 = 3

At least $3 were spend on M&Ms, meaning 4 M&Ms and 12 candy bars, which is only 16 candy pieces...

8 M&Ms and 9 candy bars is equivalent to 17 total candy pieces.
