Add the numbers 197,203 and 423 in two ways ​fast​
mr Goodwill [35]

Answer:

823

<u>Method 1</u>

Break the three numbers into hundreds, tens and units, then add these separately (starting with the units)

197 = 1 hundred, 9 tens, 7 units

203 = 2 hundreds, 0 tens, 3 units

423 = 4 hundreds, 2 tens, 3 units

Units: 7 + 3 + 3 = 13

Tens: 9 + 2 = 11 tens = 110

Hundreds: 1 + 2 + 4 = 7 hundreds = 700

Add these together: 700 + 110 + 13 = 823

<u>Method 2</u>

First add 203 to 197:

Borrow the 3 from 203 and add it to 197:  197 + 3 = 200

Add the remaining 200:  200 + 200 = 400

Now add 423 to 400:  400 + 423 = 823

⇒ 203 + 197 + 423 = (203 + 197) + 423

                                = 400 + 423

                                = 823

You are painting the walls and ceiling of a rectangular 20 x 30 ft room. The walls are 10 feet tall. You need two coats of paint
Diano4ka-milaya [45]

Answer:

The cost for painting will be $212.

Step-by-step explanation:

I am painting the walls and ceiling of a rectangular 20 x 30 ft room. The walls are 10 feet tall.

So, the total area to be painted = {2 × (20 + 30) × 10} + (20 × 30) = 1600 sq. ft.

Now, a gallon of paint covers 400 square feet and cost $53 per gallon.

So, the number of gallons of paint required will be \frac{1600}{400} = 4 gallons.

And the cost for painting will be $(4 × 53) = $212. (Answer)
