1 D (x=0 then y=-2; y=0 then x=-5)
2 D
29.999 sq. feet or 30 sq. feet
Step-by-step explanation:
The thing to remember here is the
- The conversion factor of Inch into feet
- Understanding of scale and model
- Rectangle area
Proceeding with the question
Width of the rectangle=3 inch
Height of the rectangle=4 inch
We know the area (rectangle)= height* width
Area=12 inch
²
We know that scale= sample area/original area
1/30=12/original area of the room
room area= 360 inch
²
Since the final area is needed in sq. feet
We know that 1 inch= 0.08333 feet
Thus 360 inches = 29.999 square feet or 30 square feet (approx.)
Convert 2.3 * 10^-4 and 4.6 * 10^-5 into decimals, obtain your solution; and finally, convert that number into scientific notation.
2.3 * (10^-4) = .00023
6 * 10^-5 = .00006
.00023 - .00006 = .00017
and finally, .00017 = 1.7 * 10^-4
Your answer is 1.7*10^-4
Hope this helps!
