Answer:
Step-by-step explanation:
t is the number of hours
12.24+0.11t = 12.74-0.15t
0.11t + 0.15t = 12.74 - 12.24
0.26t = 0.5
t= 0.5/0.26
t= 1.92 hours
approx to 2 hours

Answer: 52.489…
Step-by-step explanation:
Angle of elevation is 58 degrees, and the opposite value is 84 feet, so you’re lookin g for adjacent. That means you’ll use tangent to solve this equation:
Tan(58)=84/x
Answer:
36√3 + 144
Step-by-step explanation:
Given that,
base of the pyramid is an equilateral triangle with sides = 12
Formula to calculate total surface area of pyramid
<h3>
[Base Area] + 1/2 × Perimeter × [Slant Length]</h3>
Base Area
1/2 (height) (base)
1/2 (√12²-6²)(12)
6(6√3)
36√3
perimeter of base
sum of all sides = 12 + 12+ 12
= 36
slant height = √10²-6²
= 8
put all these values in the formula above
36√3 + 1/2(36)(8)
36√3 + 144
Total area for the pyramid with the equilateral base =
36√3 + 144
