L.B. Johnson Middle School held a track and field event during the school year. The chess club sold various drink and snack items for the participants and the audience. Altogether, they sold 486 items that totaled $2673. If the chess club sold each item at the same price, calculate the price of each item. Do not include units ($) in your answer.

Answers

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

please solve this equation and show work 4y−70=12y+2

Answers

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.

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.

Answers

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 need to determine how many minutes would it take the printer to use all 92 sheets of paper?

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.

Because, putting p(t)=0 means there won't be any sheet left.

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.

sin 70 in surf form

Answers

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)

8 = x*1/2

x = 8 / (1/2)

= 16

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. Let x represent the hours she number of hours she babysits and y represent the hours she works at the ice cream shop.

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:

Step-by-step explanation:

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

What is a function rule?

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

The daughters of Black Hawk merchants had a confident, unenquiring belief that they were refined, and that the country girls, who worked out, were not. The American farmers in our county were quite as hard-pressed as their neighbours from other countries. All alike had come to Nebraska with little capital and no knowledge of the soil they must subdue. All had borrowed money on their land. But no matter in what straits the Pennsylvanian or Virginian found himself, he would not let his daughters go out into service. Unless his girls could teach a country school, they sat at home in poverty. The Bohemian and Scandinavian girls could not get positions as teachers, because they had had no opportunity to learn the language. Determined to help in the struggle to clear the homestead from debt, they had no alternative but to go into service. Some of them, after they came to town, remained as serious and as discreet in behaviour as they had been when they ploughed and herded on their fathers farm. Others, like the three Bohemian Marys, tried to make up for the years of youth they had lost. But every one of them did what she had set out to do, and sent home those hard-earned dollars.
