There are 39 students.The number of students that play football is twice as much as the number of students that play volleyball.9 students play both sports.WHAT IS THE NR OF STUDENTS THAT ONLY PLAY FOOTBALL?

Answers

Answer:

Step-by-step explanation:

There are a total of 39 students.

students.

The number of students that play football is twice as much as the number of students that play volleyball.

Let the number that plays volleyball be x then the number that plays football will be 2x. This we have

x + 2x = 39

3x = 39

x = 13

The total number that plays volleyball is 13.

The total number that plays football will be 2 x 13 = 26

Since 9 students play both sports, the number of students that plays only football will be 26 - 9 = 17.

The graph of f(x) = 2x + 1 is shown below. Explain how to find the average rate of change between x = 1 and x = 3.Graph of 2 to the power of x plus 1

Answers

So we got the function of the graph f(x) = 2^x + 1 what you will need to do first is find the y-coordinates corresponding to x=1 and x=3 which can be found by substituting into the function. After that we can find the average rate of change using y2-y1/x2-x1.

f(1)=2^1+1 which would be equal to 3

1,3

f(3)=2^3+1 which would be equal to 9

3,9

9-3/3-1=6/2

6/2=3

The average rate of change is 3.

05.03)Calculate the area of the regular pentagon below: A regular pentagon with side length of 11.8 inches and dotted line from center to middle of side of 8.1 inches. 164.025 square inches 238.95 square inches 351.78 square inches 477.9 square inches

Answers

Answer:

The correct answer is 238.95 square inches

Step-by-step explanation:

Regular Pentagon : A quadrilateral having five sides each of equal length is called regular pentagon.

Side length of pentagon, a = 11.8 inches

$\text{Area of regular pentagon = }(1)/(4)\cdot \sqrt{5\cdot (5+2\cdot √(5))}* a^2\n\n\implies\text{Area = }(1)/(4)\cdot \sqrt{5\cdot (5+2\cdot √(5))}* (11.8)^2\n\n\bf\implies\textbf{Area = }239\textbf{ square inches}$

Hence, The correct answer is 238.95 square inches as it is approximately equal to 239 square inches.

Answer:

The answer is 477.9

Step-by-step explanation:

What you're going to do is base x height. Then your going to multiply you're answer to that by how many sides there are. so for this it going to be: 8.1 x 11.8 = 95.58. 95.58 x 5 = 477.9

Hope this helps!

Have an amazing day!
