Let q and n represent the number of quarters and nickels respectively.
q=3n and .05n+.25q=1.6 These are the conditions in mathematical terms.
To solve, use the value of q from the first equation in the second equation to get:
.05n+.25(3n)=1.6 carry out indicated multiplication on left side
.05n+.75n=1.6 combine like terms on left side
.8n=1.6 divide both sides by .8
n=2, since q=3n
q=6
So Peggy had 2 nickels and 6 quarters.
Answer:
The answer is below
Step-by-step explanation:
Let Y represent the profit per day, and x represent the number of bar sold per day. Hence:
Y = 0.25x - 2
a) The mean is given as:

b) The standard deviation of y is:

40x5= 200
I'm not sure who created five times more projects than the other, but whoever did, created 200 projects.
The answer should be 25.12
Let the least possible value of the smallest of 99 cosecutive integers be x and let the number whose cube is the sum be p, then

By substitution, we have that

and

.
Therefore, <span>the least possible value of the smallest of 99 consecutive positive integers whose sum is a perfect cube is 314.</span>
