What pyramid? Can you show us a picture or give us the lengths?
navik [9.2K]3 years ago
4 0
If the length of one side of the base of the pyramid is "a" the base would be
a X a.

Finding the area of the four vertical side of the pyramid is more difficult. If a diagonal line is "b," one can use sin (x) X b X 1/2 to describe the area of one triangle. However, since there are four, one would ave to multiply four to the equation. 

The total surface area would be
(a)(a)+4(sinx)(b)(1/2)

Eric earned $100 in tips on Sunday waiting tables plus an additional $11.50 per hour. He earned at least $250 in all.
snow_tiger [21]

Answer:

13

Step-by-step explanation:

So first Subtract 100 from 250. Since you are trying to find out the amount of hours, you don’t need the tips to count.

The next step is too either do the equation 150 divided by 11.50 or you can multiply 11.50 by 13.

it’s not fourteen because 149.5 is closer to 150 then 161

Hope this helps
