Answer:
Step-by-step explanation:
<u>Given infinite geometric series</u>
- 1/4, 1/5, 4/25, 16/125, ...
<u>We see that</u>
<u>Sum of the series</u>
- S = a*1/(1 -r)
- S = 1/4*1/(1 - 4/5) = 1/4*1/(1/5) = 1/4*5 = 5/4
The option is the 3rd bubble
Part one is 11 1/8.
part two is 4 7/40.
Answer:
40 cups
Step-by-step explanation:
7 part nuts and 2 parts M&M makes up 1 trail mix
7 and 2 part = 9 parts in total
There are 180 cups in total, so each part would be:
180/9 = 20 cups = 1 part
Now, we know there are 2 parts M&Ms and there are 20 cups in a part, so:
M&Ms required = 2 * 20 = 40 cups
Answer:
28
Step-by-step explanation:
x = 2 point questions, y = 3 point questions
x + y = 40
2x + 3y = 92
Solving this we get x = 28, y = 12 so the answer is 28.
