Using the combination formula, it is found that the photographs can be chosen in 5005 ways.

The order in which the photographs are chosen is not important, hence, the <u>combination formula</u> is used to solve this question.

Combination formula:

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

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

In this problem, 6 photographs are chosen from a set of 15, hence:

C_{15,6} = \frac{15!}{6!9!} = 5005

The photographs can be chosen in 5005 ways.

Select three side lengths, in centimeters (cm), that can form a right triangle. Use the Pythagorean Theorem.
lawyer [7]

Answer:

Hey there!

You can make a right triangle by the sides 6, 8, and 10. The most famous pythagorean triplet is the 3, 4, 5 triangle. Increasing the size of this triangle by a scale factor of 2 makes the sides 6, 8, and 10.

Hope this helps :)

What’s the value of the blue dot
bixtya [17]

Answer:

-22

Step-by-step explanation:

Each line is worth 3 units

-10 - (-16) = 6 units between and there are 2 spaces

6/2 = 3

We are going down so it is negative

-16 -3 =-19

then the dot is on the next line

-19 -3 = -22

Your math teacher tells you that the next test is worth 100 points and contains 38 problems. Multiple-choice questions are worth
rusak2 [61]
If we assume that
x isthe number of multiple choice questions, and y is the number of word problems, we can write a system of equations like:
{ x + y = 38
{ 2x + 5y = 100

If we multiply the first equation by -2 we get:
{ -2x-2y = -76
{ 2x + 5y = 100

Now if we add both equations we get only equation with 1 unknown (y) :

3y = 24 ⇒ y = 8

Substituting the calculated value to the first equation we get:

x + 8 = 38 ⇒ x = 30

The solution:
{ x = 30
{ y = 8

means that:
The test had 30 multiple choice questions, and 8 word problems.
