Answer:
Total number of quarters=10
Total number of nickels=19
Step-by-step explanation:
The expression for the total value of money you have is;
Quarters have a value of= $0.25
Nickels have a value of= $0.05
Total value=(value of quarters×number of quarters)+(value of nickels×number of nickels)
where;
Total value=$3.45
Value of a quarter=$0.25
number of quarters=x
Value of a nickel=0.05
number of nickels=y, but y=x+9
replacing;
3.45=(0.25×x)+0.05(x+9)
3.45=0.25 x+0.05 x+0.45
3.45=0.3 x+0.45
0.3 x=3.45-0.45
0.3 x=3
x=3/0.3
x=10
y=x+9=10+9=19
Total number of quarters=10
Total number of nickels=19
Answer:
The correct answer is option A
Step-by-step explanation:
The volume of a cylinder is given by
Substituting the values of radius and height in above equation, we get -
N means 2 matches because half of 10 is 5 and they've won 3 matches so they need to win 2 more matches.
Say that xyz is your number, then y=4z and x+3=y
Since it is a multiple of 4, y has to be 4 or 8, which means z has to be 1 or 2, since it is 1/4 of y and then since x is 3 less than y, x would have to be 1 or 5...so the numbers are....141 or 582
