Answer:
180 square feet
Step-by-step explanation:
We know that the rectangular drawing has:
- 5 inches long (L)
- 4 inches wide (W)
And we also know that:
<em>1 inch = 3 feet</em>
We will find how many feet long and wide is the actual room, by multiplying:
Long: 5 inches * 3 feet/inch = 15 feet
Wide: 4 inches * 3 feet/ inch = 12 feet
Now we want to know the area of the rectangle, and the area of the rectangle is:
<em>A = L*W</em>
<em>A = 15 feet * 12 feet</em>
A = 180 square feet
Answer:
64a³c²⁷
Step-by-step explanation:
The expression inside parentheses can be simplified by noting that b^0 = 1. Then you have ...
(4ac^9)^3
The rules of exponents say the exponent outside applies to each of the inside factors. For c^9, the exponents multiply.
Here are the applicable rules:
(ab)^c = (a^c)(b^c)
(a^b)^c = a^(b·c)
__
(4ac^9)^3 = 4^3·a^3·c^(9·3) = 64a^3c^27
Moving the decimal point one place is a factor of ten; two places is a factor of 100
So 100.
NB; three places would be 1000
