Answer:
The lengths of all sides of the triangle will be 21 cm, 21 cm, and 21 cm
Step-by-step explanation:
Given that the perimeter of the triangle = 63 cm
And the length of one side = 21 cm
and one of the medians is perpendicular to one of its angle bisectors
Since triangle has 3 sides,
Median = 63 ÷ 3 = 21
Therefore each side length = 21 cm
Answer:
Step-by-step explanation:
1. What fractional part of the brown sugar needed does she have?
The recipe says that you need 1 1/2 cups of brown sugar and she has 1 1/8, so the fraction would be
(1 1/8) / (1 1/2) = 3/4 of the total
2. What method could be used to scale down the other ingredients of the recipe in order to make it with the limited amount of brown sugar?
She has to multiply each ingridient by 3/4
3.
2 * 3/4 = 1 1/2 cups butter
2 1/4 * 3/4 = 1 11/16 cups flour
2 * 3/4 = 1 1/2 eggs
1 * 3/4 = 3/4 tsp salt
1 1/4 * 3/4 = 15/16 tsp baking soda
1 * 3/4 = 3/4 tsp vanilla
1/4 * 3/4 = 3/16 cup sugar
1 1/8 cup brown sugar
10 * 3/4 = 7 1/2 ounces choc chips
How many cookies will the scaled down recipe make?
24 * 3/4 = 18 cookies
Percent means parts out of 100 so
125.25%=125.25/100=12.525/10=1.2525/1=1.2525
basically:
percent to decimal: move decimal place 2 places to the left and get rid of percent sign
decimal to percent: move decimal place 2 places to the right and add percent sign at end
fraction to decimal: divide completely
fraction to percent: divide completely then convert to percent
the answer is 1.2525
