Find the surface area help

Mathematics
1 answer:
S_A_V [24]3 years ago
3 0

Answer:

Step-by-step explanation:

Just find the area for each individual shape, then add them all up.

3x8/2=12

3x8/2=12

7x3=21

3x8=24

We're actually missing a side value, and it's on the hypotenuse of the triangle shape, so we use this formula to find it.

8²+3²=c²

64+9=c

73=c

√73=8.5

8.5x7=59.5

Add them all up, and the final answer is...

128.5

Find the percent of change from 95 pounds to 75 pounds. Round to the nearest tenth of a percent if necessary.
mel-nik [20]

Your percentage of change would have to be about 21.05, but the full answer is 21.05263. Since we are going to need to round to the nearest percent, you would have 22% decrease. The difference in the change is -20.
