B) 509m^3
C) 7230m^3
D) 904m^3
Answers
r = (D/2) = 6 m
=(4/3)*(pi)*((6^3)
= 904.7786.. m^3
I hope this helps.

| x + 5.3 | = 4.2 / 2
| x + 5.3 | = 2.1
x + 5.3 = 2.1 x + 5.3 = - 2.1
x = 2.1 - 5.3 x = -2.1 - 5.3
x = - 3.2 x = - 7.4
solution is : x = -3.2 or x = -7.4
Answer:
What value or values of x satisfy 2|x + 5.3| = 4.2?
x can only equal –3.2.
x can only equal 7.4.
x can equal –3.2 or –7.4.
x can equal –3.2 or 7.4.
Step-by-step explanation:
x can equal –3.2 or –7.4. Is the correct answer.

313K or also 98.6*f
it cannot be a negative or the body will dye of no heat, and 313*c is well over 1000*f
so 313k (apr40c)
is the correct answer

Answer:
the right answer is:
- (A)
Step-by-step explanation:
You take the equations that the exercise give you:
- x + y = 4
- x - y = a
Now you clear the "y" variable in any equation you want, in this case, I'm gonna use the second equation:
- x - y = a
- -y = a - x
3. y = x - a
And now, you'll replace this third equation in the equation you didn't take (the first in this case).
- x + y = 4
- x + (x - a) = 4
- x + x - a = 4
Add the x variables:
- 2x - a = 4
- 2x = 4 + a
- x = (4 + a) / 2
That's the answer of the exercise, but you can represent this in this form:
- x = (4 + a) / 2 ↔
- x = (4 + a) / 2 ↔
By this reason, the right answer is .
