a 4000 pound car driving at 40 miles/hour has how many times the kinetic energy of another 4000 pound car driving at 10 miles/hour.

Answers

Answer 1
Answer = 400 I think
Explain = do 4,000 five by 40 then get a answer of 100 and then do 4,000 divid by 10 and get 400 do you see the similarities of both of these question they are the same question but just written in different ways just by adding a zero.
Answer 2

The comparison of the kinetic energy of the given bodies is required.

The first car has 16 times more the kinetic energy of the second car.

Kinetic energy

m = Mass of car = 4000 pound

[tex]v_1[/tex] = Initial velocity of car = 40 miles/hour

[tex]v_2[/tex] = Final velocity of car = 10 miles/hour

The mass of the car is constant so we have the relation

[tex]K\propto v^2[/tex]

Thus,

[tex]\dfrac{K_1}{K_2}=\dfrac{v_1^2}{v_2^2}\\\Rightarrow K_1=K_2\dfrac{40^2}{10^2}\\\Rightarrow K_1=16K_2[/tex]

Answer:

Point A is located at (8,6)

Step-by-step explanation:

As I said in the last answer I did for u, (8,6) basically means x is 8 and y is 6. If you see A, A is located on 8 for x and 6 for y. the others are incorrect such as B because B is on the 8 for x but the y is on 8. hope this helps '∆'

Answer:

A

Step-by-step explanation:

A is the answer because you look down at 8 and count up 6 times but dont count the 8 and your answer would be A ( A, 8 ) is on 6 .

Answers

Part A:

Full size car rental is $49/day, insurance is $21/day, and the total is $465 after a coupon for $25. Ok. We have to add the daily charges, then multiply that by the number of days. Next we’ll subtract his coupon, and get $465:

(49 + 21)d - 25 = 465
70d - 25 = 465
70d = 490
d = 7
7 days is this answer.

Part B:
Now that we did part A, this is a little easier to come up with an equation for, right? ;)
(39 + 21)d - 25 = 465
60d = 490
d = 8.16
8 days is this answer

Part C:
Now we don’t know the cost of the car, so that is x. But we know we still have to add that to the 21 for insurance, and multiply that sum by the 5 days they’re renting it. On the other side of the equation, Marven and his 3 friends spent $75 each, so our total is 75 x 4.

(x + 21)5 = 75 x 4
5x + 105 = 300
5x = 195
x = 39

They rented the smaller car.

Cole has a rectangular garden with an area of 16.02 square meters. What is the width, in meters, of the garden?

Answers

Answer:

3.56m

Step-by-step explanation:Parameters given:

Area of the rectangular garden = 16.02m^2

Length of the rectangular garden = 4.5m

The Area of a rectangle can be calculated for using the formula below

Area (square meters) = length (meters) × width (meters)

Therefore, 16.02m^2 = 4.5m × width

Width = 16.02m^2 / 4.5m

Width = 3.56m

Therefore the width in meters of the garden is 3.56m

See the attachment below for an illustrative diagram

A = area

l = length

w = width

16.02 divided by 2 = 8.01

Hank is throwing a surprise party. The party costs $20 per person. Create an equation and graph to represent the relationship between the cost of the party and the number of friends attending.

Complete the following table:

Number of friends (f) 5 10 15 20
Cost of party (c) 100 200 300 400

Plots the points from the table onto the graph.

Answers

Answer: Answer with Step-by-step explanation:

Since we have given that

Cost of party per person = $20.

Let the number of friends be 'f'.

Let the cost of party be 'p'.

According to question, our equation becomes

p= 2f

So, if p = 100, then f = p/2 = 100/2 = 50 if f = 10, then, p = 2f = 2 • 10 = 20 If p = 300 then, f = 300/2 = 150, If f = 20, then, p = 2f = 2 • 20 = 40 So, Table as follows:

Number of friends cost of party

50 100

10 20

150 300

20 40
