So 4 triangular faces of the pyramid will have total area
<span>= 4 ×<span>12 </span>× base × height = 4 × <span>12 </span>× 34 × 58f<span>t2 </span>= 3944f<span>t2</span></span>
So <span>3944f<span>t2</span></span> of marble cover the faces of the pyramid.
Answer:
67 units^2
Step-by-step explanation:
The surface area of the prism is found by
SA = 2 ( lw+lh + wh)
= 2 ( 5*1.5+ 4*1.5 + 5*4)
= 2 ( 7.5+6+20)
= 2 (33.5)
= 67
19.75 divided by 3.25 = m
M= 6.07692307692
Hope this helps :D
Area formula of a triangle is:
A =

We know the area and the height, so substitute to find the base
A = 70 m²
h = 8.75 m or

m (its the same thing)
70 =

× b × 8.75
70 = 4.375b
Divide by 4.375 on either sides to isolate b

4.375 and 4.375 cancels out
16 m = b
The base of this triangle is
16 m
Answer:
$12 million
Step-by-step explanation:
Vertex form of a quadratic equation:
y=a(x-h)^2+k
where (h,k) is the vertex.
The vertex is (5,12), and it is a maximum since a is negative.
Therefore, the maximum value is $12 million.
