Jack had $200 when he got to the festival. He spends $4 per ride. The equation T = 200 – 4R models his amount of money. If he has $100 left how many rides did he go on

Answers

Answer:

Step-by-step explanation:

Given the equation :

T = 200 - 4R

T = amount of money left ; if T = $100

R = number of rides

$100 = 200 - 4R

$100 - $200 = - 4R

-$100 = - 4R

R = 100/ 4

R = 25

25 rides

Can i have brainliest?

Answer:

528 Cubic Inches

Step-by-step explanation:

The first thing you would do is, since the equation states that the total height of the bench is 8 inches, is place 4 as the height of the rectangular prism piece of the bench. Next you would use of the dimensions of each of pieces of the bench to calculate the area of each piece respectively using the equation l*w*h. The equations are 4*4*25 which equals 400, 4*4*4 which equals 64, and 4*4*4 which equals 64. Next, you would add them all together which gives you a grand total of 528 cubic inches.

a certain number of two digit is three times the sum of its digit and if 45 added to it the digit will be reversed find the number ?

Let the number be (10 x + y)

Then, 10 x + y = 3 * (x + y) (given)

Or, 10 x + y = 3 x + 3 y

Or, 10 x - 3 x = 3 y - y

Or, 7x = 2 y

Or, x = 2 y / 7 ( Eq. 1)

Also, 10 x + y + 45 = 10 y + x ( given)

Or, 10 x - x = 10 y - y - 45

Or, 9 x = 9 y - 45 ( Eq. 2)

Substituting the value of x from (Eq. 1) in (Eq. 2), we have:

9 * 2 y / 7 = 9 y - 45

Or, (9 y ) - (18 y / 7) = 45

Or, 63 y - 18 y = 315

Or, 45 y = 315

Or, y = 7

From (Eq. 1),

x = 2 * 7 / 7 = 2

So, the number is 10 x + y = (10 * 2) + 7 = (20 + 7) = 27

Answer

Check:

Sum of the digits = 2 + 7 = 9

9 * 3 = 27 ✓

Adding 45 to the number 27, we get 72. So, the digits get reversed.

What is the radius of a circle whose area is equal to the sum of the areas of two circles whose radii are 20cm & 21cm?

Answers

Answer:

Step-by-step explanation:

20^2 times 3.14= 1256

21^2 times 3.14= 1384.74

the sum of those two is 2640.74

the square root of that is 29

The radius of the circle is 29 cm.

We have the circle whose area is equal to the sum of the areas of two circles whose radii are 20cm & 21cm.

We have to find the radius of the circle.

Suppose you have to find the radius of a circle whose area is equal to the sum of the areas of two circles whose radii are r and R. How will you approach it?

Let the radius of the circle be x.

We know that the area of the circle is [tex]\pi r^{2}[/tex]. Then -

[tex]\pi x^{2} =\pi r^{2} +\pi R^{2} \\x=\sqrt{r^{2} + R^{2}} \\[/tex]

Now, in the question given to us -

r = 20cm and R = 21cm and 'x' denotes the radius of the circle we have to find.

Substituting the values in the above formula, we get -

x = [tex]\sqrt{400+441}[/tex]

x =29 cm

Hence, the radius of the circle is 29 cm.

x=6

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

2(3x−5)=4x+2

(2)(3x)+(2)(−5)=4x+2(Distribute)

6x+−10=4x+2

6x−10=4x+2

Step 2: Subtract 4x from both sides.

6x−10−4x=4x+2−4x

2x−10=2

Step 3: Add 10 to both sides.

2x−10+10=2+10

2x=12

Step 4: Divide both sides by 2.

2x=12

The first two shipping companies provided their data from a sample of drivers in a table.

Company C showed its data in a dot plot.

2. What is the MAD for company C's data? Show your work.

Write your answer in the space below.

3. Which company had the greatest mean number of deliveries?

Write your answer in the space below.

4. Compare the means for companies A and B. By how many times the MAD do their means differ? Show your work.

Write your answer in the space below.

Answers

Answer:

Step-by-step explanation:

1. the company C used 10 drivers

2. 6 + 7 + 8 + 9 + 10 + 10 + 10 + 12 + 14 + 14 = 100/10. The Mean = 10

(6- 10) + (7- 10) + (8- 10) + (9- 10) + (10- 10) + (10- 10) + (10- 10) + (12- 10) + (14- 10)

4 + 3 + 2 + 1 + 0 + 0 + 0 + 2 + 4 = 16/10 = 1 6/10

3. The groups that had the most deliveries where group A and B

4. So if there are 6 deliveries of group A and 14 deliveries from group B i think the MAD would be 4

By reading the dot plot,

Number of drivers used by company C in its sample = 10

Mean absolute deviation for company C's data = 2

Company B has the greatest mean number of deliveries.

The mean deliveries of company B is 4 times MAD of company A.

What is dot plot?

Dot plot is a simple form of data visualization that consists of data points plotted as dots on a graph with an x- and y-axis.

Number of units used in the sample of a dot plot can be calculated by simple counting.

What is mean absolute deviation?

The mean absolute deviation (MAD) is the mean distance between each data value and the mean of the data set.

We are given the sum of each point from the mean. It is 20. Mean absolute deviation can be calculated by dividing this sum by number of observations.

Mean absolute deviation of company C = 20/10 = 2.

Mean A = 6

Mean B = 14

Mean B - Mean A = 8 = 4 * 2 = 4 times MAD (since MAD =2 for both companies).
