Answer:

82

Step-by-step explanation:

Vertical rectangle:

A = bh

A = (5)(10)

A = 50

Horizontal rectangle:

h = 10 - (3 + 3)

h = 4

A = bh

A = (8)(4)

A = 32

Combined:

50 + 32

82

Answer:

[tex]A=82 meters^2[/tex]

Step-by-step explanation:

First we will split the shape into two rectangles.

Now that it is in two separate peaces, solve each one individually

Remember   [tex]A = l*w[/tex]

[tex]10*5=50[/tex]

[tex]8*4=32[/tex]

Finally add the two areas together

[tex]50+32=82[/tex]

Note: if you try to do this yourself on desmos graphing calculator, make sure to add f(x) first (f(x) is: f(x) = 2^x - 4).

Ella wants to make a fruit salad for herself and 5 friends.

She has 5 cups of grapes, 3 pints of strawberries, and 1 quart of watermelon pieces.

1. How many cups of fruit salad does Ella have?

2. If she wants to share the fruit salad between herself and 5 friends, how much fruit salad will each person get?
Answer both to get brainlest. Also please explain.

Answers

1. I believe she would have 15 cups of fruit salad because it’s 5 cups of grapes, 6 cups strawberries(1 pint = 2 cups which means 6 cups of strawberries) and 4 cups of watermelon (1 pint = 4 cups
2. Since there are 15 cups of fruit salad you would need to divide 15 by the number of friends which would make it 2.5 cups of fruit salad per person
1.) 15 cups
2.) 3 cups per person
