Let k be the scale factor relating two similar prisms

and

, such that for corresponding parts of prisms

and

(for heights, in particular) we have

. In our case

.
For surfaces area we have

.
So, the right answer is 4:25 (choice B)
<em>48.25 in^2</em>
Step-by-step explanation:
The formula for the surface area of a pyramid is:

B represents the area of the base, which in this case is a triangle. We will figure out the area of the base first, using the formula for the area of a triangle.


A = 10.75
Now we can plug in 10.75 for B.

The cursive L will be the lateral height, which is 5. Since there are 3 sides on the base we can put that in for the number of base sides, and the base is 5.

48.25 in^2
Answer:
Shade 6 bars.
Step-by-step explanation:
You are asked to shade 2/3 of the strip. It is given that the strip has 9 equal parts. Multiply the number and fraction together:

You will shade 6 of the 9 bars given.

Y=mx+b
Y= -14(x-5)+4
Y= -14x+70+4
Y= -14x+74
Plot (0,74)
Then move down 14 then over left 1
