Vedmedyk [2.9K]

Answer:

9!=362880 ways

Step-by-step explanation:

It is given that there are 4 different mathematics books and 5 different science books.

So basically there are 9 different books. So we have 9 choices for the first book, 8 choices for the second book, since we have placed the first one. We have 7 choices for the third book and so on. Therefore, we can arrange 9 different books in,

!9 ways, on solving !9 we get,

$!9= 9 \times 8 \times 7 \times 6 ....\times 1= 362880$

So there are 362,880 ways to arrange 9 different books if there are no restrictions.

Robby has 9 coins that total $2.15. if he only has nickels and dimes, write the system of equations.

Illusion [34]

Let's assume

number of nickels =n

number of dimes =d

we are given

total number of coins =9

so, we get

$n+d=9$

we know that

1 nickel =$ 0.05

and

1 dimes =$0.10

so, total amount is

$=0.05\times n +0.10\times d$

we are given

total amount =$2.15

so, we get

$0.05n +0.10d=2.15$

so, we get system of equations as

$n+d=9$

$0.05n +0.10d=2.15$ ................Answer

The point (5,4) lies on a circle. What is the length of the radius of

Flura [38]

Answer:

$\large\boxed{r=2\sqrt2}$

Step-by-step explanation:

The radius (r) length is equal to the distance between the center of the circle and the point on the circle.

The formula of a distance:

$d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

Substitute the coordinates of the given points (5, 4) and (3, 2):

$r=\sqrt{(3-5)^2+(2-4)^2}\\\\r=\sqrt{(-2)^2+(-2)^2}\\\\r=\sqrt{4+4}\\\\r=\sqrt{(4)(2)}\qquad\text{use}\ \sqrt{ab}=\sqrt{a}\cdot\sqrt{b}\\\\r=\sqrt4\cdot\sqrt2\\\\\boxed{r=2\sqrt2}$
