Why doesn't a moving a object keep moving forever?

Answers

-- If a moving object speeds up, slows, down, or changes its direction, then that has to be because there's some force on it.

-- If there's no force on an object, then it keeps moving forever, at a constant speed in a straight line.

-- We can never see that happening on Earth, because around here, there's always some force on a moving object ... like gravity, friction, and air resistance. In order for it to actually happen, it pretty much has to be happening in outer space.

Examples:

-- The Earth keeps moving around the sun, and TV satellites keep moving around the Earth, without slowing down.

-- Even the International Space Station, orbiting about 270 miles above the earth's surface, is almost outside all of the atmosphere, but not quite. There's still a tiny bit of air out there, slowing it down and 'decaying' its orbit. About once a month, they have to give it a short burst of rocket fire, to boost it back up to the altitude where it's supposed to be.

Objects will actually keep moving forever unless there are other other forces to stop them. For example, if you jump right now, Gravity will pull you back to the Earth. The only time an object will keep on moving forever is in a perfect vacuum. I hope this was helpful...

Any Examples? Question: Use the data in the table to write a multiplication story for the number fact. Solve. Data in Table: 4 Bandages in 1 kit, 6 Cleanser Pads in 1 kit, and 12 Cotton Balls in 1 kit. The number fact they gave me is, 2x6. I know 2x6=12, I just need a multiplication story.

Answers

we have

$4$ Bandages in $1 kit$

$6$ Cleanser Pads in $1 kit$

$12$ Cotton Balls in $1 kit$

Multiplication Story

The amount of a Cotton Balls kit is equal to the amount of half Bandages kit multiplied by the amount of a Cleanser Pads kit. What is the amount of a Cotton Balls kit if a Bandages kit has 4 units and a Cleanser Pads kit has 6 units?

Let

x-------> amount of a Cotton Balls in $1 kit$

y-------> amount of a Bandages in $1 kit$

z-------> amount of a Cleanser Pads in $1 kit$

we know that

$x=(1)/(2) y*z$

$y=4\n z=6\n x=(1)/(2) *4*6$

$x=2*6$ --------> The number fact

$x=12$

therefore

The amount of a Cotton Balls in $1 kit$ is $12 units$

Edward buys a novel for $8.40 and a bookmark for $1.20 from a bookstore. The store is having a sale, and everything is 35% off! How much does Edward pay for both items ( not including tax )?

Answers

Let's start with calculating the $8.40 novel with the 35% off.

First, we need to convert the percentage (35%) into a decimal. We can do this by dividing the percentage over 100.

35/100 = 0.35

Now, our next step is to find 0.35% of $8.40 (original price of the novel). To do this, you need to multiply the percentage by the original price.

0.35% × $8.40 = 2.94

What we recently received (2.94), is the amount of money that we are saving from the sale. The original price of the novel was $8.40, and with the 35% off, we are saving $2.94 on it.

Our last step is to subtract the original price and the sale.

$8.40 - $2.94 = $5.46

Now - we know that our new cost just for the novel is $5.46.

------

Moving on to the bookmark which costs $1.20, we can start by taking our percentage from last time (0.35) and instantly start multiplying just like we did on the novel.

0.35% × $1.20 = $0.42

So, with the 35% discount, you are saving $0.42 on the bookmark. Let's subtract and find the total amount Edward is having to pay now.

$1.20 - $0.42 = $0.78

He will purchase the bookmark for only $0.78.

-----------

Our final step is to add both the novel and bookmark up to find the total price overall.

$5.46 + $0.78 = $6.24

Edward will have to pay $6.24 for both the novel and bookmark.

$8.40*0.65(the new price 65% of the original price that Edward needs to pay)=$5.46 $1.20*0.65=$0.78 5.46+0.78=$6.24

$46 shoes; 2.9% tax. Find the total cost to the nearest cent.

Answers

To get the answer we have to find 2.9% of 46 and add it to 46.
2.9% is 0.029
46*0.029=1.334$
46+1.334=47,334
Now we can round
47,334 is 47,33$ - its the answer
