Answer:
4x+10
Step-by-step explanation:
Emma is guaranteed to use 10 pages when she writes something. Since you can't tell how many hours she has written, you use x to represent the hours she has spent writing. If she writes 4 pages every hour, that would be 4 × (hours spent writing) or 4x. Add 4x to the original guaranteed 10 pages she uses and you have your expression.
Well if three of them end up with the same lunch box and there are only 4 total lunch boxes, then that means all of them would get their original lunchbox.
For that to happen there is a 1/4 chance for each person to correctly pick their lunchboxes.
So it’s 1/4*1/4*1/4*1/4 and that equals to 1/256.
So there is a 1/256 chance that they will end up with their original lunch box.
Hope this helps!
Answer: 2,572.441
Step-by-step explanation: use the equation for a sphere <u>4 x Rcubed x 3.14</u>
3
The quotient of 3 and 927 is 1/309.
In order to find the quotient of these two numbers, divide the first by the second.
3/927.
You can simplify this fraction by dividing each number by 3.
1/309
25
The triangle given by 9, unknown, and 15 and the triangle given by 15, unknown, and x are similar triangles and therefore 9:15 = 15:x
X is 25 in this case
