Answer:

D

Step-by-step explanation:

A_1 = a^2 = 14^2 = 196

A_2 = 4(\frac{b * h}{2}) = 4(\frac{14 * 12}{2}) = 4(\frac{168}{2}) = 4 * 84 = 336

SA = A_1 + A_2 = 196 + 336 = 532\ cm^2

If there bill was 58.65 and they gave a sever a 15% tip, how much did they pay altogether
masha68 [24]

Answer:

<u>$67.43 altogether</u>

Step-by-step explanation:

A 15% percent tip means 15% OF the bill.

15% of 58.65

0.15*58.65=8.7975

You can't really pay $8.7975, so you would round to the nearest one hundredth which is $8.78.

Now you add the $8.78 to $58.65 which will give you $67.43.

I hope that helps!
