Answer: Choice C

We start with 8 and cut each term in half to get the next term
eg: 8*1/2 = 4
The common ratio is r = 1/2 found by taking any term and dividing it over its previous term

The common ratio r  is 4/8  =  1/2 and the first term a1  = 8

an = a1 * (1/2)^(r-1)

an = 8 (1/2)^(r-1)   which is choice C.

Murrr4er [49]
This is the concept of algebra, To solve the question  we proceed as follows;
Number of chocolate cake left=23 
The number of pieces that was left after the cake was divided into 2 equal pieces will be:
23*2
=46

Number of strawberry cake left = 56
The number of pieces that was left after the cake was divided into 3 equal pieces will be:
56*3
=168

Comparing the two fraction, the flavor that had larger pieces was strawberry cake;
This cake was larger compared to chocolate by:
168-46
=122
The answer is Strawberry by 122 of a cake

If 48 feet are represented by 12 inches on a scale drawing, then a scale of 1/4 inch represents how many feet? a. 3 foot c. 2 fo
alukav5142 [94]
Hello there!

Math is hard! So we as students, we need to play the smart game with Math in order to find the easiest way to solve the problems. What do I mean? Well as you can see they gave us Fraction which won't be easy! So we will transform the fractions into decimals. So let's get started.

Then a scale of 1/4. Transformed into decimal = Then a scale of 0.25
So instead of using the fraction 1/4, I used its decimal 0.25

So if:

48 feet ......> 12 inches
x feet ........> 0.25 inches

Cross multiply

12 * x = 0.25 * 48

12x = 12
Divide both sides by 12
12x/12 = 12/12

x = 1

The correct answer is option D, 1 foot

I hope this helps! Please let me know if you have any question.

Thanks!
