Answer:
Step-by-step explanation:
Let q represent the number of quarters (the higher-value coin). Then 8-q is the number of dimes, and Jill's total amount in change is ...
0.25q +0.10(8-q) = 1.25
0.15q + 0.80 = 1.25 . . . . . . . eliminate parentheses
0.15q = 0.45 . . . . . . . . . . . . . subtract 0.80
q = 3 . . . . . . . . . . . . . . . . . . . . divide by 0.15
the number of dimes is 8-q = 8-3 = 5.
Jill has 3 quarters and 5 dimes.
Answer:
8/30
Step-by-step explanation:
Dividing fractions is almost the same as multiplying to do it you just have to flip the second fraction and change the division sign to a multiplication sign like this,
2/10×4/3
then from there, you have to multiply the top numbers and the bottom numbers
2×4=8
10×3=30
then put them together
8/30

Answer:
670.21 inches^3
Step-by-step explanation:
To find the volume of the spheres, all you need to know is the formula for the volume of a sphere, which you've included in your problem. From the problem, you also know that r = 2. From here, you calculate the volume of 1 of the spheres, which turns out to be:
V = 33.51032
Since there are 20 spheres in this box, you multiple the volume of a single sphere by 20 to get the total volume occupied by the spheres.
V = 20 * 33.51032
V = 670.2064
If you round to 2 decimal places, this becomes 670.21.
So we first have to find the mean: 41+ 38+19+ 30 +21+ 53+34+34 + 37+ 29+ 50 + 43+ 57+ 28+ 50 = 534 534/15 = 35.60
86+ 15+ 75+ 40+ 51+ 60+ 27+ 45+ 112+ 7+65+ 31+ 18+ 27+ 69 = 728728/15 = 48.53
Therefore, the store with the better representation of there data would be the competitor's store. This is because more money is being spent at the competitor's store which has an average of $49.00 when the owners store has an average of $36.00.
Hope this helps.
