A signal can be sent from one location to another by running different colored flags up a flagpole, one above the other. There are 15 different colored flags to choose from but only 4 flags will be flown. Find the number of different signals consisting of 4, if the first flag must be orange.

If the first flag is orange then the number of different signals consisting of 4 flags is ____

Answers

Answer 1

Using the combination formula, it is found that if the first flag is orange then the number of different signals consisting of 4 flags is 364.

The order in which the flags are chosen is not important, hence, the combination formula is used to solve this question.

What is the combination formula?

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

[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]

In this problem, considering that the first flag is orange, 3 flags will be chosen from a set of the remaining 14, hence the number of signals is given by:

[tex]C_{14,3} = \frac{14!}{3!11!} = 364[/tex]

What is the area of triangle ABC?

Answers

Answer:

200 sq units

Step-by-step explanation:

As you might know, 3 angles of a triangle adds up to 180*. Since you already know the angles are 60* there is one more 60*. So by this you know that all the sides are equal.

As the given states, one side is 20. So following the standard way to get the area of a triangle b*h/2; 20*20 = 400 / 2 = 200 sq units

A clothing store is selling a pair of jeans for $17 and a sweatshirt for $8. Which inequality shows the number of sweatshirts Monique can buy along with one pair of jeans if she has $41 to spend? Assume that there is no sales tax.

Answers

Answer:

1 pair of jeans and 3 sweatshirts

Step-by-step explanation:

41-17=24

24/8=3

The inequality shows the number of sweatshirts Monique can buy along with one pair of jeans if she has $41 to spend  will be; 17x + 8y ≤ 41

What is inequality?

An inequality is a mathematical statement that compares two values or expressions using a relational operator, such as less than (<), greater than (>), less than or equal to (≤), greater than or equal to (≥), or not equal to (≠). Inequalities are used to describe relationships between quantities or to express constraints or conditions.

We are given that clothing store is selling a pair of jeans for $17 and a sweatshirt for $8.

Therefore,

41-17=24

Unit price = 24/8=3

Thus 1 pair of jeans and 3 sweatshirts

The inequality shows the number of sweatshirts Monique can buy along with one pair of jeans becomes as;

17x + 8y ≤ 41

Answers

Answer:

10 > P ≥ 5

Step-by-step explanation:

inequality is a relation which makes a non-equal comparison between two numbers or other mathematical expressions

sine the price can't be greater than or equal to 10$ we set it up 10 is greater than P ( 10 > P )

sine the lowest price ever was 5$ then we know P can't be any lower than 5$ but can still be 5$ so we set up as P is greater than or equal to 5 ( P ≥ 5 )

then to get your answer you just but the two comparisons together ( 10 > P ≥ 5 )

In a survey of 3,000 people who owned a certain type of​ car, 1,050 said they would buy that type of car again. What percent of the people surveyed were satisfied with the​ car?

Answers

Answer:

35 percent

Step-by-step explanation:

1050 / 3000 as a percent

1050 / 3000 = 105 / 300

Divide both sides by 3:

300 / 3 = 100

105 / 3 = 35

35 / 100 = 35 percent

34%

This is because when you divide 1,050 by 3,000 you get 0.34 then turn that into a percent then there you go

What is the area of the shaded region?
A. 16π
B. 8π
C. 4π
D. 2π

Answers

Step-by-step explanation:

the area of a full circle (360°) is

pi×r² = pi×5² = pi×25

a 40° segment is then just 40/360 = 1/9 of the full circle.

so,

pi×r²×1/9 = pi×25/9 = pi×2.777777777...

so, either there is a mistake in the problem description, or your teacher wants you to cut off the decimals (after the decimal point), in which case D would be the right answer.

since our radius is 5, that makes r² always 25.

there are no integer factors I can divide 25 by to create any of the 4 solutions of 16 or I or 4 or 2.

and there is no integer factor I can divide 360 by to get 25.

so, something is wrong here regarding the problem description. either the radius or the angle or the solution options are wrong and not fitting to each other.
