Answer:
1 is 30, 2 is 70, 3 is 5, 4 is 5. It means 5 nickels equals 1 quarter.
Step-by-step explanation:
A nickel is 5 cent. A quarter is 25 cent. So 1 quarter is 5 nickels.
So, 6 quarters is 30 nickels. 14 quarters is 70 nickels.
Perpendicular means crossing so it would be a right angle. Therefore the 2 times will be
9:00 and 3:00
When the hour hand is at the 9 it will be perpendicular to the minute hand because they will be crossing paths if you extend the arms in both directions. The same with 3
Answer:
9 canvases
Step-by-step explanation:
To find the number of canvases Rogelio can buy, we just need to divide the value of the gift card by the value of each canvas. Then, if the result is decimal, we round down, because if we round up we will not have enough money to buy them all.
So we have that:
Number of canvases = 100 / 10.99
Number of canvases = 9.099
Rounding down, we can buy 9 canvases
Answer:
52 dimes and 28 nickels
Step-by-step explanation:
n = number of nickels
d = number of dimes
n+d = 80 the number of coins he got
Multiply the number of nickels times .05 plus the number of dimes times .10 to equal the amount of money he got
.05n + .10d = 6.60
Divide this equation by .05
.05n/.05 + .10/.05 = 6.60/.05
n + 2d = 132
n+d = 80
Multiply by -1
-n-d=-80
Add this to n+2d = 132
n+2d=132
-n-d=-80
-------------------
d = 52
Now we need to solve for n
n+d = 80
n+52 = 80
Subtract 52 from each side
n+52-52= 80-52
n = 28
