We have been given that Maria put trim around a banner that is the shape of a triangle. Each side is 21 inches long.
The amount of trim will be equal to perimeter of triangle. The perimeter of given triangle will be 3 times each side length that is
inches.
Now we need to convert 63 inches into feet.
12 inches = 1 feet
63 inches =
feet = 5.25 feet.
We are also told that Maria has
foot of trim left, so total length of trim would be trim used plus trim left that is
feet.
Since we need to find length of trim in yards, so we will convert 6 feet into yards.
3 feet = 1 yard
6 feet =
yards = 2 yards
Therefore, the length of the trim was 2 yards.
200 hours.
It’s 10km for every one hour
Divide 2000 by 10 and you will be left with the number of km for every one hour.
180 degrees - 116 degrees =64 degrees (angle PDC)
180 degrees - 64 degrees = 116 degrees (angle APD)
Quotient means that division was used so you do the opposite of division which is multiplication... so you do 12×2 and get 24 ...so 24 fast songs were played
