Complete Question

Leah would like to earn at least $120 per month. She babysits for $5 per hour and works at an ice cream shop for $10 per hour. Leah cannot work more than a total of 20 hours per month. Let x represent the number of hours Leah babysits and let y

represent the number of hours Leah works at the ice cream shop.

Answer:

The inequalities to solve this question is given as:

x + y ≤ 20

5x + 10y ≥ 120

Leah must spend: 16 hours babysitting and 4 hours working at the ice cream shop to earn at least $120

Step-by-step explanation:

Let x represent the hours she number of hours she babysits and y represent the hours she works at the ice cream shop. Leah cannot work more than a total of 20 hours per month.

Hence:

x + y ≤ 20 ...... Equation 1

Leah would like to earn at least $120 per month.

She babysits for $5 an hour and works at an ice cream shop for $10 per hour.

Hence, out Equation is given as:

x × $5 + y × $10 = $120

5x + 10y ≥ 120..... Equation 2

The inequalities to solve this question is given as:

x + y ≤ 20

5x + 10y ≥ 120

To find x and y:

x + y = 20

x = 20 - y

5x + 10y = 120

Substitute: 20 - y for x

5(20 - y) + 10y = 120

100 - 5y + 10y = 120

Collect like terms

- 5y + 10y = 120 - 100

5y = 20

y = 20/5

y = 4 hours

Note:

x = 20 - y

x = 20 - 4

x = 16 hours

Hence:

Leah must spend: 16 hours babysitting and 4 hours working at the ice cream shop to earn at least $120

Answer:

Price of each item = 5.50

Step-by-step explanation:

Total items sold = 486

Total price of items sold = $2,673

If the chess club sold each item at the same price,

Price of each item = Total price of items sold / Total items sold

= $2,673 / 486

= $5.50

Price of each item = $5.50

Excluding the units ($) in the answer

Price of each item = 5.50

Answer:

Hans has done a mistake in the second step.

The correct answer is:

5x^2+13x-6=0

5x^2+15x-2x-6x=0 - 5. -6=-30 -30=15. -2

5x(1+3x)-2x(1+3x)=0

(5x-2x)(1+3x)=0

5-2x=0 1+3x=0

Answer:

16 months for it to grow 8 inches

Answer:

16

Step-by-step explanation:

growth in 1 month = 1/2 inches

growth in x months = x*1/2 inches

total growth = 8 inches

thus,

8 = x*1/2

x = 8 / (1/2)

  = 16

Slope: -45

Y-intercept: -2

Step-by-step explanation:

The expression is written in slope-intercept form or y=mx+b.

mx is the slope and b is the slope intercept

1253/9997 or 0.12534

3/4 - 2/6 + 7/24

3/4 = 0.75

2/6 = 0.333

7/24 = 0.29166

0.333 + 0.29166 =

0.62466

0.75 - 0.62466 =

0.12534

Answer:

Step-by-step explanation:

Simplifying 4y + -70 = 12y + 2

Add -12y to each side of the equation. -70 + 4y + -12y = 2 + 12y + -12y

Add 70 to each side of the equation. -70 + 70 + -8y = 2 + 70

Divide each side by -8.

So y = -9 is your answer.

Hope I Helped!!!

Step-by-step explanation:

Calculate sin(70)°

Determine quadrant:

Since our angle is between 0 and 90 degrees, it is located in Quadrant I In the first quadrant, the values for sin, cos and tan are positive.

Determine angle type:

70 is an acute angle since it is less than 90°

sin(70) = 0.93969262030844

Write sin(70) in terms of cos

Since 70° is less than 90,

we can express this in terms of a cofunction

sin(θ) = cos(90 - θ)

sin(70) = cos(90 - 70)

sin(70) = cos(20)

Answer:

Should be x/9

Step-by-step explanation:

The inverse of the function is F' ( x ) = x/9

The function rule is the relationship between the input or domain and the output or range. A relation is a function if and only if there exists one value in the range for every domain value.

A function is a relation from a set of inputs to a set of possible outputs where each input is related to exactly one output.

Given data ,

Let the function be represented as F ( x )

Now , the value of F ( x ) is

F ( x ) = 9x  be equation (1)

Now , let the inverse of the function be represented as F' ( x )

where , the values of y are interchanged with x

So , the equation is

y = 9x

when x in interchanged ,

x = 9y

On solving for y , we get

Divide by 9 on both sides , we get

y = x / 9

So , the inverse of the function is F' ( x ) = x/9

Hence , the inverse of the function is F' ( x ) = x/9

Here is the complete question I was able to find:

Tanya is printing a report. There are 92 sheets of paper in the printer, and the number of sheets of paper p left after t minutes of printing is given by the function p(t) = -8t + 92.

How many minutes would it take the printer to use all 92 sheets of paper?

Answer:

The printer needs 11.5 minutes to use all 92 sheets of paper.

Step-by-step explanation:

Given the function

p(t) = −8t + 92

We know that putting p(t) = 0 means we will be able to determine the time when all the 92 sheets of paper will have been printed.

Thus, plug in p(t) = 0 in the function and calculate the time 't'

p(t) = −8t + 92

0 = −8t + 92

adding 8t to both sides

8t = −8t + 92 + 8t

8t = 92

dividing both sides by 8

8t/8 = 92/8

t = 11.5 minutes.

Thus, the printer needs 11.5 minutes to use all 92 sheets of paper.
