Action movies make up 85% of Devon's movie collection. If he has 20 movies,how many action movies are in Devon's collection?

Answers

Answer 1

Answer:

Method 1

We can find the number of Devon's movie collection by multiplying its percentage by the number of Action movies. That is;

Number of Devon's movie collection $= (85)/(100) * 20=(85)/(5) =17$

Method 2

We can also use ratio and proportion. According to the question, out of every 100 Action movies 85 are Devon's Movie collection. This means,

Action movies Devon's collection

100 85

20 $x$

If 100 corresponds to 85, then 20 will correspond to a less value than 85. If less more divides,Hence,

$x=(85 * 20)/(100)=17$ .

Therefore he has 17 movies that are in Devon's collection.

Answer 2

Answer: The answer is 17, because you know it’s going to be most of it, so you do 20 times .85 on your calculator, and you have your answer! :)

Which geographic feature contributed to the beginning of farming communities? A. a snowy mountain with a lot of snowmelt

B. a swampland with lots of waterfowl

C. a low-lying floodplain that had rich soil

D. arid land that relied on winter rains

Answers

Answer:

C.) A low-lying floodplain that had rich soil.

Step by Step Explanation:

Flood-plains are the large, flat expanses of land that form either side of the river.

A flood-plain is the area around the river that is covered with river water in the times of flood.

A flood-plain area is a very fertile land due to the high alluvium sediment by floodwaters.

This process makes flood-plains a good fertile land for agriculture.

The build of alluvium on the banks of rivers can create a natural dam which can increase the river bank.

I think that the answer is C. a low-lying floodplain that had rich soil

Janet is buying a $28 necklace. The store reduces the price by 20% and then applies a $2 off coupon. How much will Janet pay for the necklace? Could you show the work please? I would really appreciate it.

Answers

Original cost of the necklace = $28
Percentage by which the store reduces the price of the necklace = 20%
Amount of discount given
by the store on the necklace = (20/100) * 28
   = 28/5 dollars
   = 5.6 dollars
So
The price of the necklace after discount = (28 - 5.6) dollars
   = 22.4 dollars
Amount of discount on coupon = $2
Then
Price of the necklace after deducting coupon discount = (22.4 - 2) dollars
= 20.4 dollars
So Janet will pay 20.4 dollars for the necklace.

mr.chan made 252 cookies for the annual fifth grade class bake sale . they sold 3/4 of them and 3/9 of the remaining cookies were given to P.T.A members . mr.chan allowed the 12 student helper to divide the cookies that are left equally how many cookies will each student get. please help !!!! hurry i need help helppppppppppppppppppppppppppppppppppppppppppp

Answers

Answer

Find out the how many cookies will each student get.

To prove

As given

mr.chan made 252 cookies for the annual fifth grade class bake sale .

they sold $(3)/(4)$ of them

Than

$Number\ of\ cookies\ left = (3* 252)/(4)$

= 189

Number of cookies left after sold = 252 - 189

= 63

$(3)/(9)$ of the remaining cookies were given to P.T.A members .

Than

$Number\ of\ cookies\ left\ when\ given\ to\ P.T.A\ members = (3* 63)/(9)$

= 21

Number of cookies left after giving to P.T.A members = 63 - 21

= 42

As given

mr.chan allowed the 12 student helper to divide the cookies that are left equally.

$Each\ student\ get\ cookies =(42)/(12)$

= 3.5

Therefore the 3.5 cookies each student gets.

3¹/₂ or 3.5 cookies

Further explanation

Given:

Mr. Chan made 252 cookies for the Annual Fifth Grade Class bake sale.
They sold $(3)/(4)$ of them and $(3)/(9)$ of the remaining cookies were given to P.T.A members.
Mr. Chan allowed the 12 student helper to divide the cookies that are left equally.

Question:

How many cookies will each student get?

The Process:

Step-1

$Let \ us \ prepare \boxed{252 / 4 = 63}$

Then, let us create a suitable diagram as follows:

$\boxed{63}\boxed{63}\boxed{63}\boxed{63} = 252 \ cookies}$

So, 1 unit of diagram is equal to 63 cookies.

Mr. Chan sold $(3)/(4)$ of them, that is $\boxed{ \ 3 \ units * 63 \ cookies = 189 \ cookies \ sold \ }$
The remaining cookies are $\boxed{ \ 252 - 189 = 63 \ cookies \ }$ , or 1 unit left of the diagram above.

Step-2

$Let \ us \ prepare \boxed{63 / 9 = 7}$

Then, let us create a suitable diagram as follows:

$\boxed{7}\boxed{7}\boxed{7}\boxed{7}\boxed{7}\boxed{7}\boxed{7}\boxed{7}\boxed{7} = 63 \ cookies}$

So, 1 unit of diagram is equal to 7 cookies.

Next, $(3)/(9)$ of the remaining cookies were given to P.T.A. members, that is $\boxed{ \ 3 \ units * 7 \ cookies = 21 \ cookies \ }$ .
The last number of cookies remaining was $\boxed{ \ 6 \ units * 7 \ cookies = 42 \ cookies \ }$ or $\boxed{ \ 63 - 21 = 42 \ cookies \ }$ .

Step-3

Mr. Chan allowed the 12 student helper to divide the cookies that are left equally.

Let us calculate how many cookies will each student get.

$\boxed{ \ 42 \ cookies / 12 \ students \ }$

$\boxed{ \ = (42)/(12) \ }$

The numerator and denominator are equally divided by 6.

$\boxed{ \ = (42 / 6)/(12 / 6) \ }$

$\boxed{ \ = (7)/(2) \ }$

$\boxed{ \ = (6)/(2) + (1)/(2) \ }$

$\boxed{\boxed{ \ = 3(1)/(2) \ }}$

Thus, each student will get $3(1)/(2)$ cookies.
