Write out the formula for the Surface area of a sphere

Substitute the value for the surface area and solve for the radius.

Formula for the volume of a sphere

Hence, the volume of the sphere is 2144cm³(to the nearest whole number).
Answer:
y=5x+350
If Elena spent a total of $1000, she made 130 shirts.
Step-by-step explanation:
Let x be the number of T-shirts. Let y be the amount of money spent.
1000=5x+350
5x=650
x=130
Answer:
0.25
0.65
Step-by-step explanation:
Looking at the question, we can see that we were not given the probability of selecting a yellow ball.
Hence the probability of this is;
1-0.35-0.4 = 1-0.75 = 0.25
The probability that the selected ball is yellow is 0.25
The probability that it is not red means it is either yellow or green
What this means is that we add the probability of yellow to the probability of green
= 0.25 + 0.4 = 0.65
Here is the solution of the given problem above:
The first thing we should do is to multiply 50 and 13 3/4
13 3/4 is equivalent to 13.75 .
So, we then multiply
50 x 13.75 and we get 687.50.
so, $687.50 was the amount spent on the stock.
Now, lets find out how much they sold them for:
What we do is multiply 12 and 50
50 x 12 would be 600
We can find out the loss by subtracting
$687.50 - $600 and that gives us $ 87.50.
Therefore, the amount that is loss in selling is $87.50. The correct answer would be option B. Hope this answer helps.
Answer:
1
Step-by-step explanation:
- 3/5 divided by 12/20 = 3/5 * 20/12 = 60/60 = 1
