Find the GCF of the following monomials. -50m 4 n 7 and 40m 2 n 10

Answers

Answer:

10m^2n^7

Step-by-step explanation:

-50m^4n^7 \ and \ 40m^2n^(10)

WE need to find GCf for both monomials. GCF is the greatest common factor

-50 ->-1 \cdot 5 \cdot 5 \cdot 2

40 ->2 \cdot 2 \cdot 5 \cdot 2

GCF is 2 times 5 =10

GCF of exponent is the lowest exponent

GCF of m^4  and m^2 is m^2

GCF of n^7 and n^10 is n^7

-50m^4n^7 \ and \ 40m^2n^(10)

GCF is 10m^2n^7

Find the area of the shaded sector (It is 45 degrees with a radius of 7) Help!!!

Answers

Answer:

Step-by-step explanation:

The formula for the area of a sector is

A_(s) =(\theta )/(360)*\pi r^2

where theta is the angle given as 45 and r is the radius (7).  Plugging in we get

A_(s)=(45)/(360)*\pi  (7)^2

Simplify a bit to get

A_(s)=(1)/(8)*49\pi

which gives you, in terms of pi:

A_(s)=(49\pi )/(8)

or if you need to use the decimal form, rounded to the hundredths position:

A = 19.24

Ms. White has 15 students in her first grade class. Troy is the line leader for the week, and Mackenzie is last because she was the line leader last week. In how many different ways can Ms. Whites class line up for lunch?A.) 13!
B.) 15!
C.) 15!÷2!

Answers

The first place and 15th place are already decided, so we have to find the number of different ways that the other 13 students can line up, in the places from 2 to 14.

2nd place can be any one of 13 people.  For each of those . . .

3rd place can be any one of 12 people.  For each of those . . .

4th place can be any one of 11 people.  For each of those

13th place can be any one of 2 people.  For each of those 

14th place has to be the one student who is left.

Total number of ways that 13 students can line up in places 2 through 14 is

(13 x 12 x 11 x 10 x 9 x 8 x 7 x 6 x 5 x 4 x 3 x 2 x 1)

That number is called "thirteen factorial".  The number is 6,227,020,800 . 

When you write it in math, you write it like this:13

Katherine is three times older than Joel now. In twenty years Katherine will be six years older than Joel. How old is Katherine now?

Answers

She is currently 9 years old. 

If Katherine is 9, and Joel is 3, 20 years later they'll be 29 and 23. Katherine is 6 years older than him. 
k = 3*j;
k + 20 = 6 + (j + 20) => k = 6 + j; but k =3*j => 3*j = 6 + j => j = 3( Joel has 3 years) and k = 9 (Katherine has 9 years);
