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
Okay. 12 - 4 is 8. For the other question, you have to multiply the difference of that by 1/4. 8 * 1/4 is 2. The expression of (12 - 4) is four times the value of 1/4 * (12 - 8). and 2 is 1/4 the value of 8. The answers to this question are A , B, and C.
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.
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.
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
