Answer:
1/4 of the answer
Step-by-step explanation:
Integers can be whole numbers or they can be whole numbers with a negative sign in front of them. Individuals often refer to integers as the positive and negative numbers. Integers are -4, -3, -2, -1, 0, 1, 2, 3, 4 and so on.
TO get the decimal 8 is obviously 8.0 and for 21/40 just divide 40 for both the numerator and denominator. Then add the 8.0 with the answer you get for 40 together to get the final answer.
Question: How do you solve [3.2 x (6.1 x 6.3)] - 2.8 with PEMDAS?
PEMDAS is the order of operations with which you solve an equation. So first parentheses, then exponents, then multiplication, then division, then addition, and last subtraction.
Answer: First, you solve the parentheses in the parentheses:
>6.1 x 6.3 = 38.43
Now ur equation is: (3.2 x 38.43) - 2.8
Now you solve what's inside this parentheses:
>3.2 x 38.43 = 122.976
Now you do the subtraction, because you have already solved all of what's in the parentheses:
>122.976 - 2.8 = 120. 176
And so, your answer is 120.176
This is what your equation should look like when you're solving:
>[3.2 x (6.1 x 6.3)] - 2.8 = y
>[3.2 x (38.43)] - 2.8 = y
>(3.2 x 38.43) - 2.8 = y
>122.976 - 2.8 = y
>122.976 - 2.8 = 120. 176
Answer:
The height is 11/2
Step-by-step explanation:
We know SA = 30n
and r = 2
We are solving for h. So plug in our values
30n = 2n(2)^2 + 2n(2)h
Multiply and square on the right side terms
30n = 8n + 4nh
Divide everything by n
30 = 8 + 4h
Subtract 8 on both sides
22 = 4h
Divide by 4 on both sides
h = 22/4 = 11/2
Check:
30n = 2n(2)^2 + 2n(2)(11/2)
30n = 8n + 22n
30n = 30n
