CLAIM:

Examine the system model below, which shows a car moving along a track at two different points in time. Assume there is no friction between the car and the track.

In the before image, a car is moving along a track at a constant speed towards a motionless wheel.

In the after image, the car has contacted the wheel, which begins to spin. The car continues to travel along the track at a slower speed.

THE QUESTION:

Which Claim below best explains what causes the wheel to spin after contact with the car?

1 - The wheel stops spinning because kinetic energy was transferred from the car to the wheel.

2 - The wheel begins to spin because kinetic energy was transferred from the car to the wheel.

3 - The wheel pushes the car, causing it to go faster

4 - The wheel begins to spin because kinetic energy was transferred from the wheel to the car.

Answers

Answer 1

Answer:

The wheel moved because of the car.

Step-by-step explanation:

Answer 2

Only the car could move the wheel so yeah as I said the wheel moved by the cat

John had a total of $150. He purchased a DVD box set which costs $50 as well as a single DVD. He is left with $75. Which equation could be used to find the cost p of the DVD?

150 − 50 + 75 = p

150 + 50 + p = 75

50 + p + 75 = 150

150 + 50 + 75 = p

Answers

--Answer--

50 + p + 75 = 150

--Explanation--

The total number of money he had originally is 150. If he is left with 75, that starts us with 150 = 75 ______.

He spend something that was 50 dollars, so add that to 75 which equals 125.

Subtract 125 from 150 and you get 25. 25 is the cost of the single DVD, so we'll make 25 "p."

The cost of the DVD box set, the single DVD, and how much he is left with equals how much money he had originally.

That would make it 50 + p + 75 = 150.

Lisa ran around a rectangular field 150 m long and 50 m wide at an average speed of 100 m/min. How long did she take to complete 5 rounds?

Please include the units after the answer!!

Answers

Answer:

20 minutes

Step-by-step explanation:

To make one round of the field, Lisa will have to cover the entire perimeter of the field.

The perimeter of a rectangle = 2(l+w) Where L = length and W = width.

The multiplication of 2 means two lengths and widths that each rectangle has. The perimeter of the field = 2(150 +50) = 400m

Lisa's average running speed = 100m/min

The time taken to cover one round of the field or one perimeter of the field = 400/100 = 4 minutes.

To cover 5 rounds or 5 perimeters Lisa will take 5x4 minutes = 20 minutes.

20 minutes

Explain how the shapes shown have been sorted.

Answers

Answer:

Shapes in set A are all Quadrilaterals which are Parallelograms, whereas shapes in set B are all Quadrilaterals but one different than the other.

Hope this helps!

In both cases, we have sets of 3 quadrilaterals, such that in the first case the 3 belong to the same subset, and in B they don't.

How the shapes are sorted?

On case A, all the shapes are quadrilaterals, and the 3 figures are rhombi. So all belong to the same type of quadrilaterals, which is the type of figure with four sides, such that the opposite sides are parallel and have the same measure.

For case B we also have 3 quadrilaterals, but this time we have a rectangle, a square (which is a type of rectangle) and a non-rectangle quadrilateral. So this time, the 3 figures don't belong to the same type of quadrilaterals.

Answer:

minimum number-0

mean- 10.83

median-10

Step-by-step explanation:

Answer:

The minimum number is 0,

The mean is 11,

and the median is 10

Step-by-step explanation:

The minimum number is the smallest number in a data set, so that's 0.

The mean is the average of all the numbers, so if you add all the numbers in a data set together and then divide by the amount of numbers there are, you get the mean. 10 + 25 + 0 + 5 + 10 + 15 is 65, and 65 divided by 6 is 11. [Rounded to the nearest whole number.]

The median is the number that is right in the middle of the data set, so 10 is right in between 0 and 25.
