Well to my knowledge we need to find <span>how many people with that amount equal 2 for the amounts of peanuts. So lets go one by one.</span>
2 friends = 4/5 of a bag of peanuts left together. - 0.8 left
<span>3 friends = 6/5 of a bag of peanuts left together. - 1.2 left </span>
<span>4 friends = 8/5 of a bag of peanuts left together. - 1.6 left </span>
<span>5 friends = 10/5 of a bag of peanuts left together. - 2 left </span>
<span>So, there are 5 friends total.
5 friends

Answer:
$7.09
Step-by-step explanation:
$0.59(5) = $2.95
$2.49(4) = $9.96
$9.96 + $2.95 = $12.91
Subtract $12.91 from the original amount Johnny had.
$20 - $12.91 = $7.09

Answer:
1
Step-by-step explanation:
First, convert all the secants and cosecants to cosine and sine, respectively. Recall that
and
.
Thus:


Let's do the first part first: (Recall how to divide fractions)

For the second term:

So, all together: (same denominator; combine terms)

Note the numerator; it can be derived from the Pythagorean Identity:

Thus, we can substitute the numerator:

Everything simplifies to 1.
