10% = 0.1
10% of 5 = 10% x 5 = 0.1 x 5
therefore, the answer is $0.50
Answer:
The answer to your question is: the first option - 9/ 
Step-by-step explanation:
Process
cosФ = adjacent side / hypotenuse
-1/9 = adjacent side / hypotenuse
adjacent side = -1 hypotenuse = 9
c² = a² + b²
b² = c² - a²
b² = 81 - 1
b =
b = opposite side
But b is negative because we are in the third quadrant.
b = -
Finally csc Ф = hypotenuse / opposite side
csc Ф = - 9 / 
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
