Answer:
- 1/2
Step-by-step explanation:
(-4/5) × (- 5/8)
- 4/5 × - 5/8
First we mulitply across
The top and the bottom.
- 20 / 40
because -4 × -5 = +20
and -5 × -8 = +40
Now we simplify the fraction
- 20 / 40
= - 2 /4
= - 1/2
Because we have to simplify it and so I divided it by 10 first.
-20 ÷ 10 = -2 and -40 ÷ 10 = -4
Then I simplified it again by dividing it by 2.
-2 ÷ 2 = -1 and -4 ÷ 2 = -2
So finally we have:
-1/2
And we cannot simplify that anymore so that is the answer.
Hope that helped!
55/5 = 11
11 - 7 = 4
Answer: 55
Answer:
A. One solution
Step-by-step explanation:
To find out, we solve the equation.
6 - 3x = 12 - 6x
Add 6x to both sides. Subtract 6 from both sides.
3x = 6
Divide both sides by 3.
x = 2
Answer: A. One solution
Its 4 plus i square root of eleven
You need to find the volume of the coated sphere and then take away the volume of the original sphere.
Volume of sphere = 4 thirds x pi x r cubed
(4 x 3.14 x 12 x 12 x 12) / 3 = 7234.56
(4 x 3.14 x 9 x 9 x 9) / 3 = 3052.08
take away = 4182.48
