Answer:

<h3>             97, 485 and 197</h3>

Step-by-step explanation:

x       - the first number

One number is 5 times a first number:

5x    - "one" number (the second number)

A third number is 100 more than the first number:

x + 100   - the third number

x + 5x + x+100   - the sum of the three numbers

x + 5x + x+100 = 779

            -100         -100    

    7x = 679

   ÷7       ÷7

      x = 97

5x = 5•97 = 485

x+100 = 97 + 100 = 197

Check:

97 + 485 + 197 = 779

I’m pretty sure it’s $826.85 because deposit means to put money into something. So, you’d just add $601.85 to $225 to get your answer. I think.

lutik1710 [3]

Answer with Step-by-step explanation:

We are given that

RHS

\frac{1+Cos2x}{Sin2x}

We have to verify the identity.

We know that

1+Cos2x=2Cos^2 x

Sin2x=2SinxCos x

Using the formula

\frac{2Cos^2x}{2SinxCosx}

\frac{Cosx}{Sinx}

Cot x

By using the formula

Cotx=\frac{Cosx}{Sinx}

LHS=RHS

Hence, verified

Solnce55 [7]

Answer:

<em>630 cups</em>

Step-by-step explanation:

<u>Percentages</u>

This problem is most easily solved backward, i.e., from the final data up to the beginning.

There was a new box of cups and the worker at a snack stand opened it. He first used 30 cups from the box and the second day he uses 15% of the remaining cups in the box, and we are told that represents 90 cups.

If 15% (0.15) equals 90 cups, then the number of cups before the second day was 90/0.15 = 600 cups.

On the first day, we used 30 cups, thus the original number of cups in the box was 600+30=630 cups
