They are unlimited.
But you can easily multiply 21*28= 588 to find a common factor.
So 588 is a common factor, but there are more.

RSM wants to send four of its 18 Math Challenge teachers to a conference. How many combinations of four teachers include exactly
tatiyna

Answer:

1120 combinations of four teachers include exactly one of either Mrs. Vera or Mr. Jan.

Step-by-step explanation:

The order in which the teachers are chosen is not important, which means that the combinations formula is used to solve this question.

Combinations formula:

C_{n,x} is the number of different combinations of x objects from a set of n elements, given by the following formula.

C_{n,x} = \frac{n!}{x!(n-x)!}

In this question:

1 from a set of 2(Either Mrs. Vera or Mr. Jan).

3 from a set of 18 - 2 = 16. So

C_{2,1}C_{16,3} = \frac{2!}{1!1!} \times \frac{16!}{3!13!} = 1120

1120 combinations of four teachers include exactly one of either Mrs. Vera or Mr. Jan.

How many square meters in a room of such dimensions 5/3/4?
sdas [7]

Answer: 3.75 Square Meters

Step-by-step explanation: I am not sure exactly what you asked for here, I chose to take it as the one wall being 5 meters long, and the other being 3/4 meter long. If this was the right senario, then what you would do to solve it, and what I did, is just multiply 5*3/4 or if it makes it simpler, 5*.75

PLSSSSSSSSSSSSSSSSSSS HELPPPPPPPPPPPPPPPPPPP!!!!GUARaNTEE REWARDAmanda earned a score of 940 on a national achievement test that
MrMuchimi
To solve this question, you¨ll need to use a table of the standardized Normal distribution, or you could use a graphing calculator. The answer will be the cumulative property which will be a number with decimals. However, this represents the students who had a lower score then her, You´ll need to subtract this from 1 in order to get the opposite number, which will be the kids who scored higher. Be sure to multiply the result by 100 to get a percentage. Your answer should be 0.806 hope this helped!

Anybody can help?????
Vikentia [17]

The formula of an area of a circle:

A=\pi r^2

r - a radius

We have r = 14m. Substitute:

A=\pi\cdot14^2=196\pi\ m^2

If you want an approximate area, you can accept \pi\approx3.14

Then:

A\approx196\cdot3.14=615.44\ m^2
