hey so where's th qn?

Answer 3

MEDAL!!!!
If the scale factor of two similar solids of 5:13 what is the ratio of their corresponding areas and volumes?
A. 125:2,197 and 25:169
B. 25:169 and 125:2,197
C.10:26 and 15:39
D. 5:169 and 5:2,197

Answer 4

ITS C right

Answer 5

The scale factor, tells how many times to multiply lines, from one solid to the other, so any linear measure is increased by that amount.
But areas are measured in square units (square inches, square miles, square centimeters): that's length times width: so you'd multiply the scale factor times itself, n * n, to increase areas.
In the same way, volumes in the solid are measured in cubit units, and those spaces increase in three directions at once, so you multiply the scale factor three of them times each other, n * n * n.
(That's a rough explanation, of how it works, mainly to help one to remember, it's easier to do the same sort of questions later if you remember how it works.)
So, in your case, the ratio for the scale factor is 5/13 (or 13/5 - either way, but pick one or the other, and stay with it.
So: lines 5/13
areas: (5/13) * (5/13) = 5*5/(13*13) = 25/169.
volumes: (5/13) * (5/13) * (5/13) = (5*5*5)/(13*13*13) = 125 /2197.

Answer 6

so I'm right?

Answer 7

Check this one too huh?
The volume of two similar solids are 1,331 m^3 and 216m^3. The surface area of the larger solid is 484m^2. What is the surface area of the smaller solid?

Answer 8

A.864m^2
B.288m^2
C.144m^2
D.68m^2

Answer 9

D is my answer

Answer 10

@jessiegonzales

ITS C right ---> That answer is incorrect

D is my answer ---> That answer is also incorrect.
