If you can buy 15 bags of potatoes for $20, then how many can you buy with $4?

Mekhanik [1.2K]

Answer:

Step-by-step explanation:

15 bags for $20 can be represented with 15/20
so x bags for $4 can be represented with x/4

now if you proportion it out (ricochet), 4x15 is 60, 60 divided by 20 is 3, so you can buy 3 bags of potatoes with $4.

you could do 15/20 is 0.75

0.75 times 4 is 3, so $4 can buy you 3 bags.

Find the sum of an infinite geometric series where a1 = 180, and the common ratio is r = 3∕4 ? Question 9 options: A) 240 B) 360

Len [333]

Answer:

The sum of this geometric series is 720.

Step-by-step explanation:

The sum of a infinite geometric series is given by the following formula:

$s = \frac{a_1}{1 - r}\\$

Applying the data from the problem, we have:

$s = \frac{180}{1 - \frac{3}{4}}\\\\s = \frac{180}{\frac{4 - 3}{4}}\\\\s = \frac{180}{\frac{1}{4}}\\\\s = 180*4 = 720$

The sum of this geometric series is 720.
