PLEASE HELP MEEEE!!!

Answer:

Manny should keep the old car since he gets to spend less on it in three years compared to getting the fuel-efficient car.

Step-by-step explanation:

Step 1:

Number of miles Manny commutes per week = 160

Cost per gallon of gasoline. = $2.9

Mileage of old car = 20 miles per gallon

Maintenance cost per year of old car = $760

Cost of new car = $7000

Maintenance cost per month of new car = $10

Mileage of new car = 31 miles per gallon

Step 2:

There are 52 weeks in a year. Total distance Manny will commute in 3 years = 160 * 52 * 3 = 24960 miles

Maintenance cost of old car in 3 years = $760 * 3 = $2280

Maintenance cost of new car in 3 years = $10/month * 12 months * 3 = $360

Gasoline usage of old car in 3 years = 24960 miles/20 miles per gallon = 1248 gallons

Cost of gasoline = 1248 * $2.9 = $3619.2

Gasoline usage of new car in 3 years = 24960 miles/31 miles per gallon

Cost of gasoline = $2.9 * 24960 miles/31 miles per gallon = $2334.97 or approximately $2335

Step 3:

Total expenditure on old car for 3 years = $2280 + $3619.2 = $5899.2

Total expenditure on new car for 3 years = $7000 + $360 + $2335 = $9695

From the calculations above, Manny will spend $5899.2 on the old car compared to $9695 on the new car in three years.

Therefore, Manny should keep the old car since he gets to spend less on it in three years compared to getting the fuel-efficient car.

Answer:

[tex]y=-2x+12[/tex]

Step-by-step explanation:

We can use the point-slope form given by:

[tex]y-y_1=m(x-x_1)[/tex]

Where m is the slope and (x₁, y₁) is a point.

So, we will substitute -2 for m and (5, 2) for (x₁, y₁). This gives us:

[tex]y-(2)=-2(x-(5))[/tex]

Simplify:

[tex]y-2=-2(x-5)[/tex]

Distribute:

[tex]y-2=-2x+10[/tex]

Add 2 to both sides. Hence, our equation is:

[tex]y=-2x+12[/tex]

Answer:

180.4 inches (15.033 feet)

Step-by-step explanation:

To solve this, we convert 15.3 feet to inches. We do this by multiplying 15.3 by 12. This gets us 183.6. Now, we subtract 3.2 from 183.6. This gets us 180.4. That means the piece cut off of 180.4 inches long. To convert this to feet, we divide by 12. That gets us 15.033. That means the piece cut off is 180.4 inches long, or 15.033 feet long.

Answer:

the first one

Step-by-step explanation:

remember, in a function, x can only have one y, whereas y can have more than one x

Answer:

The first one (the one with the months)

Step-by-step explanation:

A function is when an x value doesn't have more that one y value (y can have more than one x value, though). On the teachers and pets one, Ms. Valverde has two pets, so that doesn't count. On the shapes one, the orange square is pointing to another orange square and a triangle, so that doesn't count. The last one has 7 equaling to 12 and 13, so that doesn't count. The one with the months doesn't have any x values with more than one y value, so it is a function.

Answer:

The scaled factor is 3.

Step-by-step explanation:

Consider the figure shown below:

It is given that: A rectangle N has an area of 5 square units. James drew a scaled version of Rectangle N and labeled it Rectangle P.

We need to find the scale factor which is used by James.

First, we will calculate the area of Rectangle P by counting the number of squares shown in the figure.

Area of rectangle P = 45 square unit

Let x be the scaled factor.

To scale the rectangle we need to multiply both the length and breadth of the rectangle N by x and the scaled area should be equal to 45.

[tex][x\times \text{Length} ][x \times \text{breadth}]=45[/tex]

[tex]x^2(\text{Length} \times \text{breadth})=45[/tex]

It is given that area of the rectangle N is 5 square units, so put length time breadth as 5.

[tex]x^2(5)=45[/tex]

[tex]x^2=9[/tex]

[tex]x=3[/tex]

Hence, the scaled factor is 3.

Answer:it c

Step-by-step explanation:

The Graph representation corresponds to a decreasing speed with an increasing time.

In mathematics, a graph is a visual representation or diagram that shows facts or values in an ordered way. The relationships between two or more items are frequently represented by the points on a graph.

Given:

We have the table

Time        Speed

  0               0

  2               15

  4               25

  6               45

  8               70

So, the rate of change

= (15-0) / (2-0)

= 15/2

= 7.5

and, the rate of change

= (25-15) / (4-2)

= 10/2

= 5

and, the rate of change

= (45-25) / (6-4)

= 20/2

= 10

and, the rate of change

= (70-45) / (8-6)

=  25/2

= 12.5

As, the rate of change is increasing.

and, from the graph the slope is decreasing as time increases.

Answer:

it is an equalateral triangle on a line. equalateral triangle all angles are the same. 180 degrees in a triangle so the angle in the triangle must be 60 degrees.

180 degrees on a straight line so 60 pus 40 = 100 which means 8x is 80

80 + 40 = 120 degrees

Answer:

d

Step-by-step explanation:

Answer:

12 = 4 (k - 6) (use the distributive property to get rid of the parentheses)

12 = 4k -24 (add 24 to both sides to isolate the k-term)

36 = 4k (divide both sides by 4 to get k all alone)

Answer:

D. 2 1/4.

Step-by-step explanation:

First, convert both -5 1/4 and -7 1/2 into improper fraction. These would be -21/4 and -15/2.

-21/4 - (-15/2)

Two negatives in a row make a positive.

-21/4 + 15/2

Double both the numerator and denominator of 15/2 to make it have the same denominator as -21/4. This would 30/4.

-21/4 + 30/4

Put -21 + 30 over 4 to make it a single fraction.

(-21 + 30)/4

Add -21 and 30 to get 9.

9/4

Convert 9/4 into a mixed number: 2 1/4

The answer to -5 1/4 - (-7 1/2) is 2 1/4, which is D.
