The hypotenuse is 53
Answer:
The total pair of skates rented that Friday night is 62.
Step-by-step explanation:
Let the number of pair of skates brought that week = m
Now, the admission charges for the skating ring = $8
The rental cost per skating pair =$5.50
So, the rental cost of m skating pair = m times (Cost of each Pair)
= m x $5.50 = 5.50 m
The total amount generated that day by skate selling = $341
⇒ Rental fee of m skates pair = $341
or, m (5.5) = 341
⇒ 5.5 m = 341
or, m = 341/5.5 = 62
or, m = 62
Hence, the total pair of skates rented that Friday night is 62.
The answer to this would be C
The paint required to cover 1 door is 5/4 liters.
Step-by-step explanation:
The paint required to cover 1 3/5 doors = 2 liters.
Convert mixed fraction into proper fraction.
Therefore, the paint required to cover 8/5 doors = 2 liters.
The paint required to cover 1 door = x liters.
To find x :
Comparing the given data and the unknown data.
8/5 door / 2 liters = 1 door / x liter
x = 2 × 5/8
x = 10/8
x = 5/4 liters.
The paint required to cover 1 door is 5/4 liters.
