Answer:
20%
Step-by-step explanation:
im not really good at percentages but from what i know you first make it a fraction by adding all the numbers together to get 55(denominator). then for the numerator you take the section that they want(11). 11/55 is equal to 20/100(divide 100 by 55 and multiply the quotient by 11 to get 20). 20/100 is 20%. hope this kinda helps.
Area of the triangle = 1/2 * base * <span>height
base = 16 in
</span>height = 16 in
Area = 1/2 * 16 * 16 = 128 in.

Answer:No, she does not have enough cups of sugar
Step-by-step explanation:
Sarah needs to make a cake and some cookies. The cake requires 3/4 cups of sugar. If she has 15/16 cups of sugar, then the number of cups of sugar that would be left after making the cake would be
15/16 - 3/4 = (15 - 12)/16 = 1/4
If the cookies require 3/5 cups of sugar, then the cups of sugar that she has won't be enough because
1/4 - 3/5 = (5 - 12)/5 = -7/5 cups
It means that she would need more cups of sugar.
