What is the surface area of the faces of the pyramid?
Alekssandra [29.7K]
The area of a triangle is (base*height)/2
Therefore: 12*10=120/2=60. Since there are three triangles then you multiply 60 by three. 60*3=180
Since the triangle in the middle is equilateral the height is 10. (10*10)/2=50
180+50=230
The answer is 230 inches²

Elise built a rectangular vegetable garden that is 9 feet long and has an area of 72 square feet. What is the perimeter of Elise
Papessa [141]

We have to find the width first.

72 divide by 9 = 8

To find the perimeter, you can do it two ways:

1. 9 + 8 + 9 + 8 = 34

2. 2(9) + 2(8) = 18 + 16 = 34

The answer is 34 feet.

Help need answers quick (unprofessional behavior and wrong answers will get reported)
AleksandrR [38]

Answer:

step 2 is the answer. when you start the question it's already in pemdas order. 48÷6 equals 8 then multiply it by the other 8 then you can add that quotient to the 10 which is 74 then subtract it by 7 and you get 67. step 2 goes the wrong way and ads the 8 with the 10 before multiplying the 8 by the 8 making everything go in wrong turns.

Carlos needs 2/3 cups of raisins to make one batch of oatmeal bars. How many cups of raisins does Carlos need to make 4 batches
Hitman42 [59]

Answer:

8/3 cups

Step-by-step explanation:

Since he needs 2/3 cups for each batch, and he wants to make 4 batches, we can add 2/3 4 times, or multiply 2/3 times 4.

2/3+2/3+2/3+2/3=8/3

2/3*4=8/3

He needs 8/3 cups for 4 batches.

This can also be written as a mixed number: 2 2/3 cups
