Hey there!
15 = 15/1
1/8 = 1/8
15 x 1 = 15
1 x 8 = 8
= 15/8
Simplifying 15/8 . . .
15/8 = 1 7/8
15 x 1/8 = 1 7/8 <--------
1 7/8 is your answer.
I hope this helps you.
Have a great day! :)
No need to apologize, that's why we're here.
Rectangular prism, 25x10x8
The surface area is the sum of the area of all the surfaces. We have 2 surfaces that are 25x10, two 25x8 and 2 10x8 so our total surface area is
2(25(10) + 25(8) + 10(8))=2(250+200+80)=2(530)=1060, choice B
Red marble, 15 out of 40, 15/40 = 3/8, choice B again
There's really not enough information to answer unless we assume the only ways Bart washes his car is the gas station or himself. Assuming that, the probability he washes it himself is 1 minus the probability he washes at the gas station.

, Choice D
Answer:
The correct answer would be: D
Step-by-step explanation:
C is an interior angle, so it is out of question.
That leaves D, A, and B.
A and B are not correctly put in my opinion, because both angles are put in a circle probably suggesting it is equal to 360°, even though a whole trapeziods exterior angle alone is not supposed to equal to 360° because the entirety of it is supposed to be equivalent to that amount.
Leaving D, being the correct answer
I hope this helps
This is an exercise you should actually do with real physical objects. The objects don't have to be wood and they don't have to be square for you to be able to arrange them into a rectangular shape. You can cut squares from paper, or use Scrabble™ tiles, poker chips, pennies, M&M™ candies, bottle caps, Legos™, Cheez-It™ crackers, pebbles, or any other objects of similar size and shape.
What you will find is that there are 8 possibilities, corresponding to the number of divisors of 24:
1×24, 2×12, 3×8, 4×6, 6×4, 8×3, 12×2, 24×1
_____
If you make rectangles from numbers of pieces other than 24, you will find that only two rectangles are possible for prime numbers, like 23: 1×23 or 23×1. Even numbers of tiles will all have rectangles of 1×_ and 2×_ (as well as _×1 and _×2).
Doing this sort of playing with physical objects helps you develop number sense that can serve you well later. Don't discount it.
