Answer:

the amount invested at 1% = $4100

the amount invested at 9% = $2600

Step-by-step explanation:

Hello

let

A=amount invested at 1%

B=amount invested at 9%

the total amount invested is % 6700, so

A+B=6700 (1)

the profits generated by A= (c)

c=A\frac{1}{100}

the profits generated by B=(d)

d=B\frac{9}{100}

the total profit is $275,so

275=\frac{A}{100}+0.09B\\ A=100*(275-0.09B)\\A=27500-9B\\\\replacing \ in \ (1)\\27500-9B+B=6700\\27500-6700=8B\\B=\frac{20800}{8}\\ B=2600

A=6700-B\\A=6700-2600\\A=4100

the amount invested at 1% = $4100

the amount invested at 9% = $2600

I hope it helps

Which figures demonstrate a translation?
tensa zangetsu [6.8K]

The two bottom graphs demonstrate translations.

<h3>Which figures demonstrate a translation?</h3>

We will have a translation only if:

  • The size of the figure does not change (like in option 1, which we can discard).
  • If the "direction" of the figure does not change, like in option 2, where you can see that there is a reflection.

The images where the figures are only moved a little bit are the ones that demonstrate just a translation, and these are the two lower ones.

If you want to learn more about translations:

Pavlova-9 [17]
You would need to do 10,125/45 = n, and in which case we just solve. 
10,215/45=227, so there are 227 napkins in each box.


Hope this helps and have a nice day:)
