eric plotted the graph below to show the relationship between the temperature of his city and the number of cups of lemonade he sold daily: part a: describe the relationship between the temperature of the city and the number of cups of lemonade sold part b: describe how you can make the line of the best fit. write the approximate slope and y-intercept of the line of best fit. show your work, including the points that you use to calculate the slope and y-intercept.

Answers

Answer 1

Answer:

part A: the warmer the city temp was the more lemonade that was sold so a hotter day will sell more lemonade

part B: i used points 40,8 and 90,20 and got m= 25/6 then i did y=mx+b

90=25/6(1)+b

90/1=25/6+b

25/6 25/6

and then B= 21.6

Step-by-step explanation: im not sure if i did it right so i would check i havent done this since like the 6th grade like 4 years or so ago lol

1. Mara has $640 in her bank account. If she withdraws $30 every month, in how many months will she have $370 remaining in her account

2. Make up an equation that has no solution and explain what that means. (Hint: It has to be a real explanation, not just "it doesn't work").

Answers

Answer:

610, 580, 550, 520, 490, 460, 430, 400, 370 It takes 9 months

Step-by-step explanation:

2: 1.50+x=π This problem is impossible. This is because Pi is a number that goes for infinitiy so there is no answer for x. This also means ∞ can also be an answer.

Answer:

1. 9

Step-by-step explanation:

1. Mara has $640 in her bank account, she withdraws $30 each month. We don't know how many months will she withdraw until 370$. Let's write an expression first:

640 - 30x = 370

Now, subtract both sides by 640 to get -270:

-30x = -270

Last, divide both side by -30:

-30x = 270

x = 9

Now, we know she withdraws $30 for 9 months.

2. 2 + 4(3 - 2) = x

This tells us that we do not know the answer until we solve it.

2 + 4(3 - 2) = x

2 + 12 - 8 = x

6 = x

Heather drew the scaled drawing of a train car shown below. She used the scale of 2 cm = 5 ft to complete the
drawing.
Train Car
10.8 cm
What is the actual length of the train car?
A.21.6 ft
B.27 ft
C.43.2 ft
D54 ft

Answers

Answer: c

Step-by-step explanation:

The required actual length of the train is given as 27 ft.

Given that,
Heather drew the scaled drawing of a train car shown below. She used the scale of 2 cm = 5 ft to complete the drawing.

What is the scale factor?

The scale factor is defined as the ratio of the modified change in length to the original length.

here,
As given,
2 cm = 5 ft
1 cm = 5/2 ft
Tain car length = 10.8 m
Actual length = 10.8 × 5/2 = 27 ft

Thus, the required actual length of the train is given as 27 ft.

Al and Tom are painting a shed. Working alone, Al can paint the shed in 2 hrs. Together they can paint the shed in 1.5 hours. How long would it take Tom to paint the shed on his own?

Answers

Answer:

6 hours.

Step-by-step explanation:

The formula sort of has to be invented.

rate = 1 shed / 2 hours

Tom

rate = 1 shed / x hours.

Together.

rate = 1 shed / 1.5 hours.

Equation

1 shed / 2 hours + 1 shed / x hours = 1 shed / 1.5 hours.

1/2 + 1/x = 1/1.5 Put the fractions over a common denominator.

(x + 2) / 2x = 1 / 1.5 Cross Multiply

1.5(x + 2) = 2x Remove the Brackets.

1.5x + 3 = 2x Subtract 1.5x from both sides

3 = 2x - 1.5x

3 = 0.5x Multiply both sides by 2

6 = x

It would take Al 6 hours to do the shed on his own.

A rectangle has an area of 2x2 - 19x +45 ft? What are the dimensions of the rectangle? (hint: factor)

Answers

I think the answer is (2x - 9)(x - 5)

The dimensions of the rectangle will be (2x - 9)(x - 5).

What is a quadratic equation?

A quadratic equation is a polynomial with a degree of 2 or the maximum power of the variable is 2 in quadratic equations. It has two solutions as its maximum power is 2.

Given that the area of the rectangle is represented by a quadratic equation 2x² - 19x +45.

The dimensions of the rectangle will be the factors of the quadratic equation.

2x² - 19x + 45

2x² - 10x -9x + 45= 0

2x( x - 5 )-9(x - 5)= 0

( 2x - 9 ) ( x - 5 ) = 0

Therefore, the dimensions of the rectangle will be (2x - 9)(x - 5).

Find the geometric mean between 28 and 32. Round to the nearest tenth if necessary.

Answers

Answer: The geometric mean is √24 * 32 = √768 = 16√3.

The geometric mean between 28 and 32 is 28.29 after using the formula of the geometric mean.

What is mean?

It is defined as the single number that represents the mean value for the given set of data or the closed value for each entry given in the set of data.

Let x be the geometric mean between 28 and 32

The formula for the geometric mean:

x = √(a×b)

x = √(28×32)

x = √800

x = 20√2

x = 28.284

x = 28.29

Thus, the geometric mean between 28 and 32 is 28.29 after using the formula of the geometric mean.
