Mathematics
1 answer:
sergiy2304 [10]3 years ago
4 0

Answer:

30  

Step-by-step explanation:

Each digit in a whole number has a place value, based on its position from the decimal point.

The place value of a digit increases by a factor of 10 as we move left on the place value chart and decreases by a factor of 10 as we move right.  

Numbers to the left of the decimal point increase in place value in the order: ones, tens, hundreds, etc.

The value of a digit is the digit multiplied by its place value.

So, the digit 3 in 731.8 has a value of 30.

The area of a rectangular room is 750 square feet. The width of the room is 5 feet less than the length of the room.
Gelneren [198K]

Answer:

B. y² – 5y = 750

C. 750 – y(y – 5) = 0

E. (y + 25)(y – 30) = 0

I'm assuming the 2 in the second option is supposed to be an exponent.

Step-by-step explanation:

Length = y

Width = y-5

Length × Width = Area

Area = <u>y(y-5)</u> = 750

<u>Distribute.</u>

y²-5y=750 (B is correct)

<u>If you factor the equation above</u>

(y + 25)(y – 30) = 0 (E is correct)

Area = y(y-5) = 750

<u>Subtract y(y-5) from both sides.</u>

750-y(y-5) = 0 (C is correct)

How to find the product of to the power number: 8^3. We take eight and times it by it's self 3 times to get 512.

Hope this helps!
