The pair of values below is form an inverse variation find the missing value (3,16) (10,y)

Answers

Answer 1

An inverse variation is represented as:

[tex]y=\frac{k}{x}[/tex]

To find the missing value we need to find k first. Using the first pair we have:

[tex]\begin{gathered} 16=\frac{k}{3} \\ k=3\cdot16 \\ k=48 \end{gathered}[/tex]

Now, we plug the value of k and use the second pair to find y:

[tex]\begin{gathered} y=\frac{48}{10} \\ y=\frac{24}{5} \end{gathered}[/tex]

Therefore, y=24/5.

Artrigerator contains 5 cans of diet soda and 8 cans of regular soda. If three cans of soda are randomly selected without replacement, determine the probability that all can selected are diet soda. Use combinations to determine theprobabilityThe probability that all can selected are diet soda is(Type an integer or a simplified fraction)

Answers

The total number of cans in the refrigerator is 5 + 8 = 13

The number of diet soda cans is 5 while the number of regular soda cans is 8

If three cans are selected, the probability that the can is a diet soda can is

5/13

Since it was not replaced, the number of diet soda cans left would be 4 and the total number of cans left would be 12. The probability that the next selected can is a diet can is

4/12 = 1/3

Since it was not replaced, the number of diet soda cans left would be 3 and the total number of cans left would be 11. The probability that the next selected can is a diet can is

3/11

Thus, the probability that the three selected cans are diet soda cans is

5/13 * 1/3 * 3/11 = 5/143

= 0.035

the probability that the three selected cans are diet soda cans is 0.035

Find the length of CD.express the awnser as a fraction times pie.

Answers

Given the figure of the circle B

the radius of the circle = r = BC = 9

the measure of the angle CBD = 40°

We will find the length of the arc CD

The length of the arc is given by the formula:

[tex]l=\theta\cdot r[/tex]

where: θ is the central angle opposite to the arc measured in radians

so, we will convert the given angle from degree to radian

[tex]\theta=40\cdot\frac{\pi}{180}=\frac{2}{9}\pi[/tex]

Substitute with the given values

so, the length of the arc =

Answers

Based on the dimensions of the blueprint of the house, the area of the actual living room can be found to be 735 ft²

How to find the area?

The first thing to do is to convert the dimensions on the blueprint to their actual figures.

If 1 inch on the blueprint is 7 feet, then the actual dimensions are:

= 3 inches x 7

= 21 feet

Dimension B:

= 5 inches x 7

= 35 feet

The area can then be found by:

= Dimension A x Dimension B

= 21 x 35

= 735 ft²

What is Probability ?

The area of mathematics known as probability deals with numerical representations of the likelihood that an event will occur or that a statement is true. An event's probability is a number between 0 and 1, where, roughly speaking, 0 denotes the event's impossibility and 1 denotes certainty.

Ten times are spent flipping coins.

You can calculate the perimeter of a triangle knowing the coordinates, by calculating the distance between every point, as follows:

[tex]\bar{KL}=\sqrt[]{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]

Where x1=-4, y1=-1, x2=-2 and y2=2, replace these values:

Now According to the question:

Does the train go the same distance each minute?

In order to determine if the train travels the same distance each minute, the average speed of the train has to be determined. Average speed is the total distance travelled per time.

Average speed = total distance / total time

Average speed when distance is = 6/ 2 = 3 km/hrAverage speed when distance is = 9/3 = 3 km/hrAverage speed when distance is = 14/7 = 2 km/hr

Given the definitions of f(x) and g(x) below, find the value of (gof)(9). f(x) = -x + 11 g(x) = 3x2 - x + 14

Answers

In this case, we'll have to carry out several steps to find the solution.

Step 01:

Data

f(x) = -x + 11

g(x) = 3x² - x + 14​

(gof)(9) = ?

Step 02:

(gof)(x) = 3(-x+11)² - (-x+11) + 14​

= 3(x² + 2(-x)(11) + 121) + x - 11 + 14

= 3(x² - 22x + 121) + x - 11 + 14

= 3x² - 66x + 363 + x - 11 + 14

= 3x² - 65x + 366

(gof)(9) = 3(9)² - 65(9) + 366

Explanation:

Given that Sam reads 30 pages of books in 40 minutes, he reads at the rate of 3 pages in 4 minutes (3/4 = 0.75).

To know which of the options has the same rate as Sam's, we need to find which rate is equal to his'

A. Francine reads 40 pages in 55 minutes

Rate = 40/55 = 8/11

B. Leroy reads 22.5 pages in 30 minutes

Rate = 22.5/30 = 0.75

C. Paul reads 150 pages in 3.25 hours. Since 3.25 hours = 195 minutes

Rate = 150/195 = 0.77

D. Bill reads 60 pages in 2 hours
