Okay, so we start at '$82'

$82

let's add $100

$82+$100=$182

lets add another 100

$82+$100+$100=$282

lets add another $100

$82+$100+$100+$100=382

lets add another $100

$82+$100+$100+$100+$100=$482

Now we can't add another $100, since that will take us to $582, and we need to get to $512, so lets add $20....

$82+$100+$100+$100+$100+$20=$502

Okay, we're getting really close! Let's add $10.

$82+$100+$100+$100+$100+$20+$10=$512

(If you were to show your work on a number line, you would simply keep moving up by $100 until you couldn't anymore, and then move up by $20, and finally by $10, until we get to $512)
__________________________________________
a simpler way to solve this...

Okay, so we start at '$82'

$82

let's add $400

$82+$400=$482

now lets add $30

$82+$400+$30=$512


**Hope this helps....

To do this we will just use the DISTRIBUTIVE property to answer it. 

We will add 100 5 times and then 12 in the end.

We will start with $82.

82 + 100 = 182

182 + 100 = 282

282 + 100 = 382

382 + 100 = 482

482 + 100 = 582

OK, so we have done $500.   

Now we will add 12. 

582 + 12 = 594

So, Our answer is $594. 

Hope I helped ya!!!!!!!!

kondor19780726 [428]

Answer:

(40+2b)cm

Step-by-step explanation:

Complete question

Jimmy is putting up a fence around his rectangular garden. One side of the garden is 20 feet long, and b represents the width, How much fencing material will he need.

To get the amount of fencing material needed, we will find the perimeter of the fence

perimeter of the fence = 2(L+W)

L is the length

W is the width

Given

Length = 20feet

Width = b feet

perimeter of the fence = 2(20+b)

perimeter of the fence = 2(20) + 2b

perimeter of the fence = 40+2b cm

Hence the amount of material needed will be (40+2b)cm

In the local frisbee league, teams have 7 members and each of the 4 teams takes turns hosting tournaments. At each tournament, e
mars1129 [50]

There are 4 teams in total and each team has 7 members. One of the team will be the host team.

Tournament committee will be made from 3 members from the host team and 2 members from each of the three remaining teams. Selecting the members for tournament committee is a combinations problem. We have to select 3 members out 7 for host team and 2 members out of 7 from each of the remaining 3 teams.

So total number of possible 9 member tournament committees will be equal to:

7C3 \times 7C2 \times 7C2 \times 7C2\\ \\  = 324135

This is the case when a host team is fixed. Since any team can be the host team, there are 4 possible ways to select a host team. So the total number of possible 9 member tournament committee will be:

9 \times 324135\\ \\  =2917215

Therefore, there are 2917215 possible 9 member tournament committees
