Nata [24]

Answer:

The money Rachael plan to collect for the shelter is <u>$350</u>.

Step-by-step explanation:

Given:

Rachel is collecting donations for the local animal shelter.

So far she has collected $245, which is 70% of what she hopes to collect.

Now, to find the money Rachael plan to collect for the shelter.

Let the total amount Rachael plan to collect be x.

Amount she collected = $245.

Percentage of amount she collected = 70%.

Now, to get the amount Rachael plan to collect we put an equation:

70\%\ of\ x=\$245.

⇒ \frac{70}{100} \times x=245

⇒ 0.70\times x=245

⇒ 0.70x=245

<em>Dividing both sides by 0.70 we get:</em>

⇒ x=\$350.

Therefore, the money Rachael plan to collect for the shelter is $350.

Show how you would simplify the following expressions. Show your work.
Nutka1998 [239]
If you multiply numbers with the same base, their exponents would add while their base stays the same.

1. 3 + (-5) = -2
4^ -2 = 1/4^2 = 1/16

2. -2+ (-4) = -6
3^-6 = 1/3^6 = 1/729
