Answer:

500%

Step-by-step explanation:

We find the volume of pyramid A

Pyramid A is a square pyramid with a base side length of 9 inches and a height of 10 inches.

Volume = a² h/3

Where a = 9 in

h = 10 in

Volume = 9² × 10/3

Volume = 270 cubic inches

Pyramid B has a volume of 1,350 cubic inches.

Step 2

We compare both volumes

Pyramid A : Pyramid B

270: 1350

= 270/ 1350

= 1 /5

Hence, Pyramid B is 5 times bigthan ger pyramid A

In percent, it is the volume of Pyramid B 500% bigger than Pyramid A

Lin says that the inequalities h>150 and h<160 describe her height in centimeters. what do the inequalities tell us about
Arisa [49]

Answer:

Her height is in between 150 and 160

Step-by-step explanation:

Given

h > 150

h < 160

Required

What do these represent?

First, the inequalities need to be combined.

If h < 160, then this means that 160 > h.

So, h > 150 and 160 > h can be combined to form an inequality in the following form;

160 > h > 150

This.meeans 160 is greater than h and h is greater than 150.

If this is related to her height, it means 160 is greater than her height and her height is greater than 150;

In other words, her height is in between 150 and 160
