Two rectangular picture frames have the same area of 45 square inches but have different side lengths. Frame A has a length of 6
Vilka [71]

9514 1404 393

Answer:

  1. the longer frame (B) has the shorter width

  2. the shorter width is 6 3/7 inches, area divided by length

Step-by-step explanation:

The relation between area, length, and width is ...

  A = LW

Then the width is ...

  W = A/L . . . . .  inversely proportional to length

__

1. Since length and width are inversely proportional (when area is constant), the shorter width will be associated with the longer length. Frame B will have the shorter width.

__

2. The width of frame B is ...

  W = A/L = (45 in²)/(7 in) = 45/7 in = 6 3/7 in

Agora chess club has 16 members and gains a new memeber every month. The key club has 4 members and gains 4 new members every mo
svlad2 [7]

Answer:

For chess club:

y1 = 16 + 1*x where y1=total number of members after x months  

For film club

y2 = 4 + 4*x where y2=total number of members after x months  

y1 = y2 at  

16 + x = 4 + 4x

3x = 12  

x = 4  

Therefore, after 4 months they the same number of members (equals 20 members, 16 + 1*4 or 4 + 4*4).

Linda read 1/5 of a book on Friday and 2/7 of the book on Saturday. On Sunday she read 5/9 of the remaining pages. What fraction
insens350 [35]
Here, you just want to solve it by finding a common denominator.
1/5+2/7, because she read 1/5 and 2/7 of the book on separate days. The common denominator is 35.
7/35+10/35
=17/35
So that's how much of the book she read before Saturday.
Now it says that on Sunday she read 5/9 of the remaining pages, meaning:
1-17/35 should give us our answer
35/35-17/35=18/35
But since it says she read 5/9 of the remaining pages, we need to multiply 18/35 by 5/9 to get what 5/9ths of 18/35 is.
(18/35)(5/9)=2/7
Therefore she read 2/7ths of the book on Sunday.
