Step-by-step explanation:
Its will be the same if hes is trying to keep the ratios the same i think
Area of triangle = (base x height)/2
There are all together 4 triangles and 1 square.
Therefore, surface area = area of square + 4 x area of triangle
height = 5.8 in, base = 6 in. area of square = 6x6 = 36 in^2.
area of 1 triangle = (5.8x6)/2
area of 4 triangles = 2x5.8x6 = 69.6 in^2
surface area = 69.6 + 36 = 105.6 in^2
Answer:
8.65.
Step-by-step explanation:
B is halfway between 8.6 and 8.7.
Therefore B is 8.65.
The answer is 78.
54/9 = 6
6x4 = 24
54+24 =78
Answer:
Last choice. d.
Step-by-step explanation:
We are given the first term and the sixth term.
The first term is
.
The sixth them is
.
Let's solve for the common ratio, r.

Divide both sides by -9:

Take the fifth root of both sides:


So the common ratio is 4.
