Answer: 75 feet²
Step-by-step explanation:
The scale means that for every one unit in the scale drawing, it is 30 units in the actual room. We will convert the dimensions using proportions.
x = 90
-
x = 120
The area of a rectangle can be found by multiplying the length by the width:
A = L * W
A = 90 * 120
A = 10,800 inches²
To get this into square feet, we will divide by 144. Why? There are 12 inches in a foot. 12 times 12 is 144.
10,800 inches² / 144 = 75 feet²
The area of the room, in square feet, is 75 feet².
Amount of Joelle earns per hour is $7.50
Amount that Joelle earns during extra hours =1 1/2 or 7.5=3/2*7.5=11.25
thus given that she worked for 42 hours, the total amount earned will be as follows:
amount earned in regular hours=40×7.5=$300
amount earned overtime=11.25×2=22.5
Thus the total amount earned:
300+22.5
=$322.5
the total amount earned during that week is $322.5
Simplifying:
2t+-7=1
Reorder the terms:
-7+2t=1
Solving variable for "t."
Move all terms containing "t" to the left
Add "7" to each side of the equation
-7+7+2+=1+7
Combine the terms
-7+7=0
0+2+=1+7
2t=17
Combine the like terms:
1+7=8
2t=8
Divide each side by 2. You now have: t=4
Good luck, hope this helped! :)
