as a car drives down the road, its tires spin on their axles. how many times does a tire on a car spin around before needing replacement?

Answers

The number of times a tire on a car spins around before needing replacement depends on various factors such as the type of tire, driving conditions, maintenance, and the lifespan of the tire. It is not possible to provide an exact number without considering these factors. However, we can estimate the lifespan of a tire based on the tire manufacturer's specifications. Tire manufacturers typically provide an estimated mileage rating, such as 40,000 miles or 60,000 miles. This rating indicates the expected mileage before the tire may need replacement. For example, if a tire has an estimated mileage rating of 60,000 miles, we can assume that it will rotate approximately 60,000 times before needing replacement. This assumes that the tire wears evenly and is properly maintained. It's important to note that other factors, such as driving habits, road conditions, and tire maintenance, can affect the lifespan of a tire. Regular inspections, proper tire pressure, and rotation can help extend the life of the tire. The number of times a tire on a car spins around before needing replacement is variable and depends on factors such as the type of tire, driving conditions, maintenance, and the tire's estimated mileage rating provided by the manufacturer.

What is the measure of an interior angle of a regular decagon

1) b. -2/3
2) a. -1
3) -33/16 (no correct answer from the choices)

Explanation
The slope of a line is simply the gradient.
The gradient is the ratio of change in y to change in x.
Gradient = (y2-y1)/(x2-x1)

Question 1
Slope =((7-1))/((1-10) )=6/(-9)=-2/3

Question 2
Slope = (6.1-3.1)/(-5.5—2.5)=3/(-3)=-1

Question 3
Slope = (5/2—3)/(-5—7/3)=(11/2)/(-8/3)=-33/16

For question 3, there is no correct answer.  

Answer:

The slope  of the line that passes through the pair of points (1, 7) and (10, 1) is    (-2)/(3)

The slope of the line that passes through the points (-5.5, 6.1) and (-2.5, 3.1) is -1

The slope of the line that passes through the pair of points (-7/3, -3) and (-5, 5/2) is  (-33)/(16)

Step-by-step explanation:

Formula of slope of line (m) : (y_2-y_1)/(x_2-x_1)

Part 1 : Points are (1, 7) and (10, 1)

(x_1,y_1) =(1,7)

(x_2,y_2) =(10,1)

So, using formula

Slope (m) =(1-7)/(10-1)

                =(-6)/(9)

                 =(-2)/(3)

Thus the slope  of the line that passes through the pair of points (1, 7) and (10, 1) is    (-2)/(3)

Part 2:Points (-5.5, 6.1) and (-2.5, 3.1)

(x_1,y_1) =(-5.5,6.1)

(x_2,y_2) =(-2.5,3.1)

So, using formula

Slope (m) =(3.1-6.1)/(-2.5-(-5.5))

                =(-3)/(3)

                 = -1

Thus the slope of the line that passes through the points (-5.5, 6.1) and (-2.5, 3.1) is -1

Part 3 : Points (-7/3, -3) and (-5, 5/2)

(x_1,y_1) =(-7/3,-3)

(x_2,y_2) =(-5,5/2)

So, using formula

Slope (m) =((5)/(2)-(-3))/(-5-((-7)/(3)))

                =((5)/(2)+3)/(-5+(7)/(3))

                =(-33)/(16)

Thus the slope of the line that passes through the pair of points (-7/3, -3) and (-5, 5/2) is  (-33)/(16)

Gerald bought a home for $300,000. His largest up-front cost is 10 percent, or $30,000. What is this cost called?

Answers

It is called 'down payment'.

Answer:

Down payment.

Step-by-step explanation:

We have been given that Gerald bought a home for $300,000. His largest up-front cost is 10 percent, or $30,000. We are asked to determine the name of the given cost.

We know that when something is bought on credit, an initial payment is needed to be paid and that is known as down-payment.

Therefore, the given cost is known as the down payment.
