There are 10 computers and 5 students. How many ways are there for the students to sit at the computers if no computer has more
mestny [16]

Answer:

30,240 ways

Step-by-step explanation:

This question is bothered on permutation. Permutation has to do with arrangement.

If there are 10 computers and 5 students, the number of ways students will sit at the computers if no computer has more than one student can be expressed as;

10P5 = 10!/(10-5)!

10P5 = 10!/(5)!

10P5 = 10*9*8*7*6*5!/5!

10P5 = 10*9*8*7*6

10P5 = 30,240

Hence the number of ways is 30,240 ways

Answer:

YZ = 8.5

Step-by-step explanation:

Since RY is an angle bisector then the ratio of the sides of the triangle are equal to the corresponding ratio of the base, that is

\frac{YX}{YZ} = \frac{XR}{ZR} , substitute values

\frac{11.9}{YZ} = \frac{7}{5} ( cross- multiply )

7YZ = 59.5 ( divide both sides by 7 )

YZ = 8.5

Gianna is going to throw a ball from the top floor of her middle school. When she throws the ball from 48feet above the ground,
My name is Ann [436]

Answer: t = 3seconds

Step-by-step explanation:

To find the zero means we will equate the function to zero and then solve, that is

-16t^{2}+ 32t + 48 = 0

by factorizing , we have

(t+1)(-16t+48) = 0

Therefore:

t = -1 or t = 3

since time can not be negative , then , t = 3 seconds

Which is a good comparison of the estimated sum and the actual sum of 7 7/8 + 2 2/11?
Ipatiy [6.2K]
7 7/8 can be estimated to 8

2 2/11 can be estimated to 2

8 + 2 = 10


7 7/8 = 56+7/8 = 63/8

2 2/11 = 22+2/11 = 24/11

63/8 + 24/11 = 693+192/88 = 10.06

So do you see how similar 10 and 10.06 are to each other? :)
