Evan earned $26 for 4 hours of babysitting.
What equation can be used to model his
total earnings y for babysitting x hours?
Then graph the equation on the coordinate
plane. What is the unit rate? How is that
represented on the graph?​

Answers

Answer 1
$26 / 4 hours= $6.5/ hour
Answer 2

The equation y = 6.5x will represent the situation and the unit rate will be $6.5/hour.

How to plot a graph?

A graph is a diagram that shows the fluctuation of one variable in relation to one or more other variables.

In order to plot the graph, we need to find out y's values corresponding to x's value

After that, we need to substitute the values of x's and y's into the coordinate geometry.

Given that,

Evan earned $26 for 4 hours of babysitting.

If total earnings y for babysitting x hours then,

y = (26/4)x ⇒ y = 6.5x will be the equation.

The unit rate of the function is y/x = $6.5/hour.

Hence "The equation y = 6.5x will represent the situation and the unit rate will be $6.5/hour".

—7y - 17 = -38 show your work​

Answers

Answer:

y = 3

Step-by-step explanation:

Given

- 7y - 17 = - 38 ( add 17 to both sides )

- 7y = - 21 ( divide both sides by - 7 )

y = 3

Answer:

[tex]y=3[/tex]

Step-by-step explanation:

[tex]-7y - 17 = -38[/tex]

Add 17 both sides

[tex]-7y - 17 + 17= -38+17[/tex]

[tex]7y= -21[/tex]

Divide both sides by -7

Answer:

y=640-3x

Step-by-step explanation:

The total amount of ounces in the bucket is 640, and it decreases by 3 each minute. For example, if you plug in 3 for x into that equation (which would represent 3 minutes), you would lose 9 ounces of water, which makes sense in the terms of the equation.

The sum of three numbers is 123. The second number is 9 less than two times the first number. The third number is six more than three times the first number. Find the three numbers

Answers

Answer:

          21, 33 and 69

Step-by-step explanation:

x        - the first number

2x      - two times the first number

2x-9     - 9 less than two times the first number = the second number

3x      - three times the first number

3x+6     -  six more than three times the first number = the third number  

The sum of three numbers is 123:

x + 2x-9 + 3x+6 =123

    6x - 3 = 123

      6x = 126

        x = 21

2x-9 = 2•21-9 = 33

3x+6 = 3•21+6 = 69

Check:  21+33+69 = 123

A seat on a Ferris wheel is level with the center of the wheel. The diameter of the wheel is 200 feet. Suppose the wheel rotates 60°, causing the height of the seat to decrease. How much closer to the ground is the seat after the is to be determined.


What are trigonometric equations?

These are the equation that contains trigonometric operators such as sin, cos.. etc.. In algebraic operation.

Diameter = 200
Radius = Diameter/2 = 100
Rotational angle = 60°
Let the height be h
tan60 = h/100
√3 = h/100
100√3 = h

Thus, the required height of the seat from the ground is 100√3. Option D is correct.

The table shows the number of condo sales per month for a new condo building. Select all the equations that could represent the number of sales.

Answers

Answer:

Option (1) and (5)

Step-by-step explanation:

Let the equation representing number of sold is,

y - y' = m(x - x')

Where m = number of condo sold per month  

(x', y') is a point from the given table,

Slope of line passing through two points [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex] = [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]

Slope of the passing through (1, 8) and (0, 11) will be,

m = [tex]\frac{11-8}{0-1}[/tex] = -3

Therefore, equation of the line passing through (3, 2) and slope (-3),

y - 2 = (-3)(x - 3)

y - 2 = -3(x - 3)

Similarly, equation of the line passing through (0, 1) and slope (-3),

y - 11 = -3(x - 0)

Therefore, Option (1) and (5) will be the answer.

Answers

Answer:

30 trees

Step-by-step explanation:

Given the policy:

8 trees are cut down 48 trees will be planted

If homeowner is going to cut down five trees on his property how many trees will be planted

Since :

8 trees cut down = 48 planted

5 trees cut down = X

Cross multiply :

8 * X = 48 * 5

8X = 240

X = 240/8

X = 30

Hence, 30 trees will need to be planted

Apply the power rule and multiply exponents,  [tex](a^{m})^{n} =a^{mn}[/tex]

3³([tex]\frac{1}{3}[/tex])

The simplified value of exponential expression27(1/3) is about equivalent to 3.

Here, we have,

give that,

the expression is 27^1/3.

We know,

An exponential expression is a mathematical expression that requires raising a variable to a power.

now, we get,

Rewrite  27  as  3 ³.

so, we have, (3³)^1/3

Apply the power rule and multiply exponents,  nᵃᵇ= (nᵃ)ᵇ

3³^(1/3) = 3

i.e. we have,

(27)^1/3

= (3^3)^1/3

= 3

As 3*3*3 is 27 so we can write 3^3 ...both power got cancelled hence we got 3 as a answer.

Hence, The simplified value of exponential expression27(1/3) is about equivalent to 3.

During flu season, there were 93 students out of school on a particular day. If this is 12% of the total number of students at the school, how many total students are enrolled at the school?

Answers

775 students.
12/100=93/?
100x93=9300
9300/12=775

The total students that are enrolled at the school is = 868 students

Calculation of total students

In the flu season the number of students absent from school = 93

The percentage of students absent from school = 12%

If 93 students = 12%

X students = 100%

Make X the subject of formula,

X = 93× 100/12

X= 9300/12

X = 775

Therefore, 775 + 93 = 868

The total students that are enrolled at the school is = 868 students.

Amelia ,Hayden and Sophie did a test the total for the test was 75 marks Amelia got 56% of 75 marks Hayden got 8/15 0f the 75 marks Sophie got 43 out of 75 marks who got the highest
​

Answers

Step-by-step explanation:

Amelia got 56% of 75 so

(56/100)*75=(56*75)/100=4200/100=42

Hayden got 8/15 of 75 so

(8/15)*75=(8*75)/15=600/15=40

and Sophie that got 43 out of 75

so we see that Sophie got the highest points.

Given parameters:

  Total test score = 75marks

 Percentage of Amelia score  = 56%

 Fraction  of Hayden's score = [tex]\frac{8}{15}[/tex]

  Sophie's score  = 43marks

Unknown:

The person with the highest score  = ?

Solution:

  Since total score = 75marks;

Amelia's score = [tex]\frac{56}{100} x 75[/tex]   = 42marks

 Hayden's score = [tex]\frac{8}{15} x 75[/tex]   = 40marks

 Sophie's score  = 43 marks

The person with the highest score is Sophie with a mark of 43.
