Answer:
Step-by-step explanation:
Given
Shape: Sphere
Solving (a): The Volume
This is calculated as:
Take 
as 3.14 and substitute 14 for r
Solving (b): The Surface Area
This is calculated as follows:
Take as 3.14 and substitute 14 for r
X -length
y wide
x=4y
2x+2y=12,5
x=4y
8y+2y=12,5
x=4y
y=1,25
x=5
y=1,25
area
x*y=5*1,25=6,25
Answer: Depends....could be anything...one example is 8/14
Step-by-step explanation:
Answer:
x = 1/5
Step-by-step explanation:
Step 1: Write equation
-5x - (-7 - 4x) = -2(3x - 4)
Step 2: Solve for <em>x</em>
- <u>Distribute:</u> -5x + 7 + 4x = -6x + 8
- <u>Combine like terms:</u> -x + 7 = -6x + 8
- <u>Add 6x to both sides:</u> 5x + 7 = 8
- <u>Subtract 7 on both sides:</u> 5x = 1
- <u>Divide by 5 on both sides:</u> x = 1/5
Step 3: Check
<em>Plug in x to verify it's a solution.</em>
-5(1/5) - (-7 - 4(1/5)) = -2(3(1/5) - 4)
-1 - (-7 - 4/5) = -2(3/5 - 4)
-1 - (-39/5) = -2(-17/5)
-1 + 39/5 = 34/5
34/5 = 34/5
