Answer 1

Answer:

Ok, so I worked out the problem.

So for part a) you just multiply 8 by 25% then add the product to get the new perimeter.

Part B you Add all sides for the original square and the new square to get the perimeters of each then you divide the old square perimeter by the new square perimeter to get the percentage.

Part C you get the areas pf bother squares then divide the old square area by the new square area to get the percentage change.

If you have any questions, let me know.

Games at the carnival cost $3 each. The prizes awarded to winners cost the owner $145.65. How many games must be played for the owner of the game to make at least $50?

Answers

Profit is the financial benefit relied when revenue generated from a business activity. The number of the games must be played for the owner of the game to make at least $50 is 63.

Given information-

The cost of the games at the carnival is $3 each.

The prizes awarded to winners cost the owner $145.65.

Profit of the owner is $50.

Profit

Profit is the financial benefit relied when revenue generated from a business activity.

As the winning amount of the game is $145.65 and the owner has to earn the $50. Therefore the amount of the game should be the sum of winning price and the profit. Suppose x is the total money of the game played. Therefore,

$x=145.65+50\nx=195.65$

Hence the total price is $195.65. The cost of the each game is $3. Thus the number of game n to be played are,

$n=(195.65)/(3) \nn=65.21667$

Hence the number of the games must be played for the owner of the game to make at least $50 is 63.

What is 4/9 divded by 1/3

Answers

Easiest way is to flip the divisor and multply.

4/9 divided by 1/3
is the same as 4/9 times 3/1

Should be pretty easy to go the rest of the way yourself.

a/b divided by c/d=a/b time d/c
the reason it works is

you have
$( (4)/(9) )/( (1)/(3) )$
fractions in the denomenator is scary
make it one
remember that a/b times b/a=1 so 1/3 times 3/1=1
times the whole thing by 1 to keep is same
$( (4)/(9) )/( (1)/(3) )$ times $( (3)/(1) )/( (3)/(1) )$ =
$( ((4)/(9))((3)/(1)) )/( ((1)/(3))((3)/(1)) )$ =
$( (12)/(9) )/( (3)/(3) )$ =
$( (12)/(9) )/( 1)$ =
12/9=4/3
