Answer:

y = 70x + 35

Step-by-step explanation:

$75 - $5 = $70 (this is the amount charged minus the amount needed to get the job done per car wash)

the +35 is the tips extra/ constant that will be added after the jobs are done.

x is the amount of car washes done

y would be the profit received.

thus y = 70x + 35 (profit = value of car wash * number of cars washed + tips)

Answer:

Step-by-step explanation:

Profit = Income less outgo

         = (car wash income + tips) - (supplies)

$250 = ($75n + $35) - ($5n), or

$215  = $70n     (where n represents the number of cars washed)

This comes out to n = $215/$70, or approximately 3 car washes.

Answer:

1176 cm squared

Step-by-step explanation:

top: 1/2*6*16 = 3*16 = 48 cm squared

sides: 30*16 + 2(30*10) = 480 + 600 = 1,080 cm squared

bottom: same as top, so 48 cm squared

altogether: 48 + 1080 + 48 = 1080 + 96 = 1176 cm squared

hopefully this is correct

Answer: From the table we see there is a relation between x and y values

Every step change of x = 0.5, every step change of y = 2

This relation is linear. The formula for linear function is:

y = mx + b

Using to pairs of points to get the slope and y-intercept

(0, 60) and (1, 64)

Calculating the slope:

m = (64 - 60)/(1 - 0) = 4/1 = 4

y - intercept is 60 as per point (0, 60)

So the function is

y = 4x + 60

Part A

Yes. Described above

Part B

y = 4x + 60

Part C

Slope is the steepness of the line.

y -intercept is the lowest score with no time spent studying

HOPE I HELPED ! Have a great day :)

The number of hours students spent studying and the score on the science test are in linear correlation , a function that best fits the data is y = 4x + 60 and the slope and y-intercept of the plot indicate that y -intercept is the lowest score with no time spent studying

Linear Correlation is a measure of the degree to which two variables vary together, or a measure of the intensity of the association between two variables.

The steps are as follow:

m = (64 - 60)/(1 - 0) = 4/1 = 4

So, the number of hours students spent studying and the score on the science test are in linear correlation , a function that best fits the data is y = 4x + 60 and the slope and y-intercept of the plot indicate that y -intercept is the lowest score with no time spent studying

Answer:

1. 75 grams of Toasty Oats for 9 grams of protein

2. Toasty Oats

Step-by-step explanation:

By using cross multiplication we can figure out how many grams of Toasty Oats is needed for 9 grams of protein:

[tex]\frac{12}{100}* \frac{9}{x}[/tex] (x) being the grams of toasty oats.

Cross multiply: 12x = 900

solve for x: 900/12 = x

x = 75 grams of toasty oats needed for 9 grams of protein

To find which one has the better ratio of proteins to grams of cereal,

we can multiply the amount of cereal together to get the same denominator

12/100 and 5/45

12/100 * 9

5/45 * 20

to get the same denominator

108/900 and 100/900

we can see the (12/100)*9 has more protein to grams of cereal ratio than (5/45)*20.

Natalie and Juan collect marbles. The number of marbles that Natalie has is 4 more than 3 times the number of marbles Juan has. If m represents the number of marbles Juan has, which of the following expressions represents the number of marbles Natalie has?

A) 4m + 3

B) 3m + 4

C) 3m – 4

if Natalie has 4 more ( adding 4 more marbles) marbles that are already 3 times Juan has ( multiplying by 3) then the answers for A and C don't make since the amount of marbles is multiplied by 3 and adds 4. Bis the correct option.

Hannah baked twice the number of cookies Sam baked. Sam baked 36 cookies. Let c represent the number of cookies Hannah baked.

Which equation shows an equality between two different ways of expressing how many cookies Sam baked?

A) 36 = c – 2

B) 36 = c + 2

C) 36 = c ÷ 2

if Hannah made twice as many cookie as Sam that means the amount of cookies Hannah made are equivalent to 36 x 2= c. if we were to multiply 36 x2 we'd get how many cookies Hannah made and if we needed to find out how many Sam made we'd have to divide  Hannah's cookies by two. giving us 36 = c ÷ 2. making C the correct option.

Question 1. 3.75 x 922

Step-by-step explanation:

for question 1 if u noticed that they both have the same numbers in the same order the only difference is where the decimal point is placed. First u need to anylase both equations to do that u need to look at 922 and 9.22 not the 3.75  and 37.5 because the decimal point doesn't justify anything. So you see 922 is bigger than 9.22. So the answer is 3.75 x 922.

Answer:

The mean would be 6, meaning Tara is correct.

Step-by-step explanation:

The reason to why this is the answer is that I had to add all the “number of hours in a school per day” to get 30. Then, you would have to divide 30 by 5 (because you have five different hours for a school day) to get 6. Your mean would be 6 because mean is adding up the amount of something, then dividing it of how many numbers you added.

Tara think correct mean i.e., 6 . The student spends a mean of 6 hours in school each day.

Tara is correct.

Arithmetic mean or mean or average is the number that is obtained by adding the values of all the items of a series and dividing it by the number of observations.

As per given that :

Time slots (in hours): 4, 5, 6, 7, 8

Sample A: 70 100 125 135 70

Sample B: 80 90 120 125 85

For Sample A, the mean will be

[tex]\frac{\sum fx}{\sum f}[/tex]= [tex]\frac{3035}{500}[/tex]

      =6.07

For Sample B, the mean will be

[tex]\frac{\sum fx}{\sum f}[/tex]= [tex]\frac{3045}{500}[/tex]

      =6.09

The average mean will be = [tex]\frac{6.07+6.09}{2}[/tex]

                                            =6.08

Tara assumed the correct mean.

Answer:

896

Step-by-step explanation:

Let's talk first about how many 3 digit numbers there are. The first 3 digit number is 100 and the last is 999. So there are 999-100+1 numbers that are 3 digits long. That simplifies to 900.

Now let's find how many of those have a sum for the digits being 1, then 2 ? Then take that sum away from the 900 to see how many 3 digit numbers have the sum of their digits being more than 2.

3 digit numbers with sum of 1:

The first and only number is 100 since 1+0+0=1.

We can't include 010 or 001 because these aren't really three digits long.

3 digit numbers with sum of 2:

The first number is 101 since 1+0+1=2.

The second number is 110 since 1+1+0=2.

The third number is 200 since 2+0+0=2.

That's the last of those. We could only use 0,1, and 2 here.... Anything with a 3 in it would give us something larger than or equal to 3.

So there are 900-1-3 numbers who are 3 digits long and whose sum of digits is greater than 2.

This answer simplifies to 896.

Answer:

Answer: Wheref(the) is the distance in kilometers and the input the is the time in hours

BC f(t) = -5t + 40

CD f(t) = 20. Or f(t)= -20(t/t)+40 OR f(t) = 0t + 20

DE f(t) = -5(t-2) + 40

Step-by-step explanation:

The negative slope means that the distance is decreasing by 5 km/hr when there is movement. Between hours of 4 and 5, the slope is 0, but the distance remains constant at 20. All the options for CD are strange. But they describe the line segment in the graph.

Plug in the values of the hours to check.

Answer:

point form (-2,3)

Equation form

x=-2, y=3

Step-by-step explanation:

solve for the first variable in one of the equation, then substitute the result into the other equation.

Answer:

(-2,3)

Step-by-step explanation:

5x=5y-25

x=y-5    divide both sides by 5

use substitution.

2(y-5)+3y=5

2y-10+3y=5    distribute the parenthesis

5y-10=5    combine like terms

5y=15    add 10 to both sides

y=3    divide both sides by 5 to get y alone

5x=5(3)-25    replace y with 3, the value we found above

5x=15-25    multiply 5 and 3

5x=-10    subtract 25 from 15

x=-2    divide both sides by 5 to get x alone

Answer:

1. 28

2. -65

Step-by-step explanation:

The rule I learned, was that if there is an even number of negative signs, the outcome is positive. If there is an odd number of negative signs, the outcome is negative.

In the first question, we have 2 negative signs. So the outcome is positive. 28 is positive.

In the second, we have 3 negative signs, so the outcome is negative. -65 is negative.

Answer:

Length of A: 9

Width of A: 6

Length of B: 9

Width of B: 3

Step-by-step explanation:

If you look at the diagram, you can see that the length of rectangles A and B are the same, and are also the same as they were in the original square. We can find the length of each side by finding the square root of the area of the square to give us the length and width of the square which is 9. Now that we know that the length of both rectangles A and B, we can find the width of both rectangles by taking 9, and splitting it into 3 portions of 3. Since the ratio of area is 2:1, we could also do this with the area, but since we know the lengths are the same, we know the widths are proportional to the area. Using the ratio of 2:1, and the 3 portions of 3, you can combine 2 of these portions to get 6, and since the ratio 6:3 is proportional to 2:1, these measurements can be used as the width of each rectangle. Thus, the answer given above.

Answer:

Length of A: 9

Width of A: 6

Length of B: 9

Width of B: 3
