Aaron tracks the time it takes him to mow lawns by writing coordinate points relating x, the time in hours it takes to mow a lawn, and y, the area of land mowed in acres. Two of his points are (3, 1.5) and (5, 2.5). Which statement describes the slope of the line through these two points?

Answers

Answer 1

Answer: Also need to be increase different then level more of the level

An electrician charges a flat fee plus an hourly rate for a service call. She charges a total of $94 for a 3-hour service call on Monday and $130 for a 5-hour service call on Tuesday. How much should she charge for a 2-hour service call?

Answers

When the charge for 3 hours is $94 on Monday and $130 for 5- hour service on Tuesday would charge for 2-hour call service is $76.

Electricians charge a fixed rate + an hourly rate. The charges are a total of $94 for a 3-hour service call on Monday and $130 for a 5-hour service call on Tuesday.

How to solve the linear equation?

A linear equation is a one-degree equation. The equation includes the variable of the highest power one. The standard form of an equation is Ax + B = 0, where x is the variable, A is the coefficient and B is a constant.

To solve the linear equation we need to find the unknown variable which satisfied the given linear equation.

Electricians charge a fixed rate + an hourly rate

If he charges, $94 for a 3-hour call on Monday and $130 for a 5-hour call on Tuesday then charging for 2 extra hours is the difference between the two amounts.

130 - 94 = $36

for an hourly rate, it will be $18

For the fixed traveling charge, we will subtract the 3-hour rate from a fixed rate of $94 - 3 × $18 = $40

So, for x hour call the equation will be, 40 + 18x

for 2 hour service, the charges would be 40 + 18 × 2 = $76

Therefore, when the charge for 3 hours is $94 on Monday and $130 for 5- hour service on Tuesday would charge for 2-hour call service is $76.

First you need to find what the hourly rate is and what the flat rate is. The hourly rate is $18 and the flat rate is $40. Then you add $40+ (18x). Substitute 2 in for x for the hours and get $76.

Answer: The integers are 36, 38, 40, and 42

Step-by-step explanation:

156/2=78

Find even integers by dividing that by two. 39.

So the two middle integers are 38 and 40.

eric has been donating books he no longer needs to his local library. after 3 months of donating, he had 157 books left in his room. after 8 months of donating, he had 102 books left in his room. how many books per month did eric donate on average between monhs 3 and 8?

Answers

157 - 102 = 55
-----------------------
8-3 = 5

55/5 = 11 books

he donated 18 books per month. you first finds the difference of the books then do use the number of books by the number of months (in this case it was 5 months)

Find the distance and midpoint for the following coordinates.
P(7.6 , 10.1) and Q(4.6 , 3.1)

Answers

Solving for the midpoint:

x - coordinate: (7.6 + 4.6)/2 = 6.1
y - coordinate: (10.1 + 3.1)/2 = 6.6

Midpoint: (6.1 , 6.6)

Solving for the distance:

Distance formula: sqrt( (x2 - x1)^2 + (y2 - y1)^2 )

D = sqrt( (7.6 - 4.6)^2 + (10.1 - 3.1)^2 )
D = sqrt( 3^2 + 7^2)
D = sqrt(58)
D = 7.62 units

Distance = 7.62 units
