He wants to make it 10.1 m long and 4.2 m wide. however, in order to avoid Bugs Bunny from entering his garden he must make a fence surrounding the garden. He decides to make the fence 11.2 m long and 5.0 m wide. What is the area btw the fence and the garden?

thxs

OpenStudy (anonymous):

can anyone help me with this

OpenStudy (anonymous):

how r u sending people ??

OpenStudy (anonymous):

ohh duh

OpenStudy (anonymous):

can anyone help me with this

OpenStudy (anonymous):

the fence forms a large rectangle, and the garden forms a smaller rectangle inside it. So what you need is the difference between the area of the large rectangle and the small one.

OpenStudy (anonymous):

do you know how to find the are of a rectangle ?

OpenStudy (anonymous):

no i dont

OpenStudy (anonymous):

RectangleArea = Width * Length

OpenStudy (anonymous):

Area between the fence and the garden = Area of the fence - Area of the garden = 11.2 x 5.0 -10.1 x 4.2 = 56 - 42.42 = 13.58 square meter Hope this helps.

OpenStudy (anonymous):

this is my summer hw and my teacher stupid and i start school in a week and he gave it to use yesturday how stupid and we never even gone over this

OpenStudy (anonymous):

thxs mimig97 could u help with other word problems if u free

OpenStudy (anonymous):

sure.

OpenStudy (anonymous):

so the answer for 1. would be

OpenStudy (anonymous):

13.58 square metter

OpenStudy (anonymous):

Yes it would. :)

OpenStudy (anonymous):

ok let me type up 2. word probelm kk

OpenStudy (anonymous):

allrighty. :)

2. amy passed around a basket of strawberries to the girls at her party. Before the party she ate 5 strawberries and gave a friend 3. Eight girls arrived at the party. the first girl took a starwberry, the second girl took 3 berry, and third gilr took 5 starberry and so on. after the last girl took her starwberry, the basket was empty. Hwo many strawberries were in the basket at the begining.

OpenStudy (anonymous):

I hope this not to hard

OpenStudy (anonymous):

so start with figuring out, how many strawberries where eaten... do you know how to do that?

OpenStudy (anonymous):

the next ones word problems are much shorter

OpenStudy (anonymous):

I dont know do i add

OpenStudy (anonymous):

Yees, you add the strawberry's that it says the girls ate.

OpenStudy (anonymous):

so 17

OpenStudy (anonymous):

so far

OpenStudy (anonymous):

then it says "and so on" so i'm assuming that it means there will be a pattern to the next 5 girls. So lets figure out the pattern

OpenStudy (anonymous):

kk

OpenStudy (anonymous):

it seems like its 5 3 1 5 3

OpenStudy (anonymous):

close 5 3 1 3 5...

OpenStudy (anonymous):

ok

OpenStudy (anonymous):

so if it's a pattern it's looking like it'll be going 531351531351 etc.

OpenStudy (anonymous):

so if i add them up i get 34 ?

OpenStudy (anonymous):

Very good. 34 strawberries. :) Next question?

OpenStudy (anonymous):

jenny bought 7 t-shirts, one for each of her seven brothers. for \$9.95 each. the cashier charged her an additional \$13.07 in sales tax. She left the store with a \$7.28. How much money did Jenny start with?

OpenStudy (anonymous):

okay, here is what we need to find out... 1) What is the total amount the shirts would cost without the sales tax? 2) If there is an additional \$13.07 sales tax how much did the cashier charge her in total? 3) How much did Jenny start with?

OpenStudy (anonymous):

brb srry

OpenStudy (anonymous):

that's fine. :P

OpenStudy (anonymous):

kk

OpenStudy (anonymous):

she wil have 69.65

OpenStudy (anonymous):

and i cant find the last 2 of your ? 's

OpenStudy (anonymous):

1) What is the total amount the shirts would cost without the sales tax? 69.65 correct. 2) If there is an additional \$13.07 sales tax how much did the cashier charge her in total? add the 13.07 tax to the 6 9.65 total. 3) How much did Jenny start with? It says she left the store with 7.28 so take the answer to 2nd question and add 7.28 to it to see how much she had total.

OpenStudy (anonymous):

82.72

OpenStudy (anonymous):

\$90.00

OpenStudy (anonymous):

Uh, no it's 90.00. I'm not sure how you got your answer... but it's 90.

OpenStudy (anonymous):

no u said add 13.07 to 69

OpenStudy (anonymous):

then add the 7.28... to see how much she had at the begining.. sorry. :/

OpenStudy (anonymous):

its fine so answer is 90.00

OpenStudy (anonymous):

ok next ? we almost done with long word problems two more

OpenStudy (anonymous):

yup.

The magician said "The average of seven numbers is 49. If 1 is added to the fisr number, 2 is added to the second number, 3 is added to the third number and so on up to seventh number". what is the new average ?

OpenStudy (anonymous):

1) The average is already calculated. What is the average of the numbers 1 through 7? 2) What would the new average be?

OpenStudy (anonymous):

??

OpenStudy (anonymous):

Oh and I was wrong on the strawberry question... i just double checked my work and it's 72... sorry bout that.

OpenStudy (anonymous):

Okay, figure it out with this equation.... 49 + (1+2+3+4+5+6+7)/7 = ??

OpenStudy (anonymous):

averages are all the numbers added up, divided by the number of items added. :)

OpenStudy (anonymous):

okk

OpenStudy (anonymous):

hey i might lose my pwoer from the hurrican Im in bahamas on vacation we couldnt leave no flights avail
