PLS HELP I WILL BRAINLIEST 15 PTS

An ice cream truck sells ice cream between 2 p.m. and 10 p.m. each night in the summer. At the end of the night, the driver calculates his profits and makes a graph to analyze the data. What is the average rate of change for the data from the 2nd hour to the 6th hour? Be sure to include the correct units of measurement.

a scatter plot with x axis labeled Hour and y axis labeled Money Earned in Dollars per Hour with points at 1 comma 54 and 2 comma 58 and 3 comma 64 and 4 comma 78 and 5 comma 96 and 6 comma 126 and 7 comma 99 and 8 comma 75

17 hours
68 dollars
17 dollars per hour per hour
68 dollars per hour per hour

Answer:

Step-by-step explanation:

1). Let the distance of the race = x feet

   Speed of hare = 250 feet per hour

   If it takes the time to complete the race = t hours

   Since, Speed = [tex]\frac{\text{Distance}}{\text{Time}}[/tex]

   250 = [tex]\frac{x}{t}[/tex]

   t = [tex]\frac{x}{250}[/tex]

2). Speed of tortoise = 50 feet per hour

   Time taken by the tortoise [tex]t_1=\frac{x}{50}[/tex]

   So the equations will be,

   t = [tex]\frac{x}{250}[/tex] -------(1)

   [tex]t_1=\frac{x}{50}[/tex] -------(2)

3). Since, tortoise took 8 hours longer than hare,

   [tex]t_1[/tex] - t = 8

   [tex]\frac{x}{50}- \frac{x}{250}=8[/tex]

   [tex]\frac{(5-1)x}{250}=8[/tex]

   [tex]\frac{4x}{250}=8[/tex]

   x = [tex]\frac{250\times 8}{4}[/tex]

   x = 500 feet  

Answer:

A

Step-by-step explanation:

The fact you need to use is 47%

47/100 * 47/100 = 2209 / 10000 = 0.221

Answer:

1.8

Step-by-step explanation:

Answer:

6 is 30 percent of 20 STEP 1 6 = 30% × Y

STEP 2 6 =  

30

100

× Y

Multiplying both sides by 100 and dividing both sides of the equation by 30 we will arrive at:

STEP 3 Y = 6 ×  

100

30

STEP 4 Y = 6 × 100 ÷ 30

STEP 5 Y = 20

Finally, we have found the value of Y which is 20 and that is our answer.

You can easily calculate a similar type of calculation by using any regular calculator, simply enter 6 × 100 ÷ 30 and you will get your answer which is 20

Step-by-step explanation:

Answer:

Max p = 28x + 41y

Subject to

59x + 58y ≤ 3660

21x + 34y ≤ 4020

x  ≥  0, y ≥ 0

Step-by-step explanation:

As given ,

                                       Windbreakers          Rain breakers              Total

Finishing time                         59 min                     58 min                   61 hr

Packaging time                        21 min                      34 min                   68 hr

Profit                                          28                                41

Let

The number of windbreaker jackets they should produce = x

The number of rain breaker jackets they should produce = y

As given,

The company wants to maximize profit.

⇒ Maximum Profit , p = 28x + 41 y

Now,

As 1 hour = 60 min

⇒61 hours = 61×60 = 3660 min

and 67 hours = 67×60 = 4020 min

∴ we get

The equations become

59x + 58y ≤ 3660

21x + 34y ≤ 4020

x  ≥  0, y ≥ 0

So, the Linear Programming Problem (LPP) for this problem is -

Max p = 28x + 41y

Subject to

59x + 58y ≤ 3660

21x + 34y ≤ 4020

x  ≥  0, y ≥ 0

18.9 or 18 9/10 or b or the second option.

Answer:

it's 18 9/10

Step-by-step explanation:

Answer:

1. Y = -4/3

2. 2x = 2y + 10

Step-by-step explanation:

1.  y =− 2y − 4

Step 1: Add 2y to both sides.

y + 2y = −2y − 4 + 2y

3y = −4

Step 2: Divide both sides by 3.

3y/3 = -4/3

y = -4/3

2.  solve for x

y=1/2x-5

Step 1: Flip the equation.

1/2x−5=y

Step 2: Add 5 to both sides.

1/2x−5+5=y+5

1/2x=y+5

Step 3: Divide both sides by 1/2.

1/2x/1/2=y+5/1/2

x=2y+10

not sure if this will help but here you go :)

Answer:

My answer is 8

Step-by-step explanation:

I calculate the area of all the shapes and added them together

the square comes first = the formlula = a  to the power of 2  or just L x W =  2 x 2 = 4

The traingles - the formula = the height x base/2 2 x 2 /2 = 2  ( but there are two traingles so) 2 x 2 = 4

add the two shapes areas together = 4+4 = 8

5q - 21/14 = 1

First add 21/14 to both sides to get:

5q = 1 21/14

Simplify the right side:

21/14 = 3/2 = 1 1/2

Now you have 5q = 2 1/2

Divide both sides by 5:

q = 1/2

Answer:

The cup would contain 10.16 ounces.

Step-by-step explanation:

When the distribution is normal, we use the z-score formula.

In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the zscore of a measure X is given by:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.

Mean of 10 ounces, standard deviation of 1 ounce:

This means that [tex]\mu = 10, \sigma = 1[/tex]

If we simulated the filling process, and had the random number .564, how many ounces would the cup contain?

This means that we have to find X when Z has a pvalue of 0.564. So X when Z = 0.16. So

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]0.16 = \frac{X - 10}{1}[/tex]

[tex]X - 10 = 0.16*1[/tex]

[tex]X = 10.16[/tex]

The cup would contain 10.16 ounces.

Answer:

[tex]0.7[/tex] is the probability that the piston chosen from Machine 1 is satisfactory and the piston chosen from Machine 2 is unsatisfactory

Step-by-step explanation:

The two events are independent of each other.

Hence the probability of choosing satisfactory piston from Machine 1 and unsatisfactory piston from Machine 2 is equal  probability of choosing satisfactory piston from Machine 1 + probability of choosing unsatisfactory piston from Machine 2

Substituting the given values we get

Probability of choosing satisfactory piston from Machine 1 and unsatisfactory piston from Machine 2 =[tex]\frac{174}{174 +116} + \frac{20}{180 +20}[/tex]

=[tex]\frac{174}{174 +116} + \frac{20}{180 +20}[/tex]

=[tex]= \frac{174}{290} + \frac{20}{200}\\= 0.6 + 0.1\\= 0.7[/tex]

Answer:

The ratio of boys to girls in the simplest form is 7:8

Step-by-step explanation:

There are 14 boys and 16 girls in a class. The ratio of boys to girls in the class is 14:16 or 7:8.

The slope of the line is 1.

The slope of the line is 1 because the line moves ror goes up from left to right, making it a positive. The line also moves one block over and one block up.

Answer:

[tex]Factor = 220 \%[/tex]

Step-by-step explanation:

Given

[tex]Initial = 2\frac{1}{2}[/tex]

[tex]Final = 5\frac{1}{2}[/tex]

Required

Determine the factor of increment

First, we calculate the percentage increment

[tex]\% Increment = \frac{Final - Initial}{Initial} * 100\%[/tex]

Substitute values for Final and Initial

[tex]\% Increment = \frac{5\frac{1}{2} - 2\frac{1}{2}}{2\frac{1}{2}} * 100\%[/tex]

Express fractions as decimals

[tex]\% Increment = \frac{5.5 - 2.5}{2.5} * 100\%[/tex]

[tex]\% Increment = \frac{3}{2.5} * 100\%[/tex]

[tex]\% Increment = \frac{3* 100}{2.5} \%[/tex]

[tex]\% Increment = \frac{300}{2.5} \%[/tex]

[tex]\% Increment = 120 \%[/tex]

So, the factor of increment is:

[tex]Factor = 100\% + Increment[/tex]

[tex]Factor = 100\% + 120 \%[/tex]

[tex]Factor = 220 \%[/tex]

Answer:

Artaud is 15 years old

Step-by-step explanation:

Imagine Artaud is x yearrs old.

Now, turning the words in the problem into math equations, we get:

-x + 42 = 27.

Solving for x, we get:

-x = -15

x = 15.

So, Artaud is 15 years old.

Answer:

The width of the walkway is of 12.86 feet.

Step-by-step explanation:

Area of a rectangle:

The area of a rectangle of length l and width w is given by:

A = lw

A rectangular garden has a width of 10 feet and a length of 14 feet.

So the area of the rectangular garden is of 10*14 = 140 square feet.

The area of the garden and the walkway together are 320 square feet.

So the area of the walkaway is of 320 - 140 = 180 square feet.

What is the width of the walkway

It has the same length of the garden, of 14. So

[tex]14w = 180[/tex]

[tex]w = \frac{180}{14}[/tex]

[tex]w = 12.86[/tex]

The width of the walkway is of 12.86 feet.
