Hello!
To find the amount of cups that has the same amount of each type of fruit and with nothing left over, we can find the greatest common factors for each type of fruit.
25 = 1, 5, 25
15 = 1, 3, 5, 15
50 = 1, 2, 5, 10, 25, 50
Since 5 is a common factor in all the numbers, Melody would make 5 cups.
To find the amount of fruit she needs to put in every cup, we can divide the amount of each fruit by five cups.
25 grapes / 5 cups = 5 grapes/cup
15 strawberries / 5 cups = 3 strawberries/cup
50 blueberries / 5 cups = 10 blueberries/cup
Therefore, she will make 5 cups of fruit salad with 5 grapes, 3 strawberries, and 10 blueberries in each cup.
This picture is a square and inside the square we can see 4 piece of a circle.
The area of a piece of a circle=1/4 (area of a circle with radius = 9 m/2=4.5 m)
Therefore:
the area of a 4 piece of a circle=area of a circle with radius=4.5 m).
Area of the shaded region=area of the square -area of a circle.
1) we compute the area of the square:
area of a square=side²
Data:
side=9 cm
Area of this square=(9 m)²=81 m².
2) we compute the area of a circle with 4.5 m of radius.
area of a circle=πr²
area of this circle=π(4.5 m)²=20.25π m²
3) we calculate the area of the shaded region:
area of the shaded region=area of the square - area of the circle
area of the shaded region=81 m²-20.25π m²≈17.38 m²
Area= about 17.38 m²
Answer:
100
Step-by-step explanation:
we start by subtracting 20 from 70, which is 50
we double 50 to get 100
