Answer:
57 Square Feet
Step-by-step explanation:
First, we determine the area of the parallelogram shaped parking space.
Area of a Parallelogram= base X Perpendicular Height
= 17X9=153 Square feet.
Next, we determine the area of the car packed on the space.
The space where the car is packed is 16 feet long and 6 feet wide.
This suggests a rectangular shape.
Area of the Packed Car
Length X Breadth=16X6= 96 Square feet.
Finally, we determine the area of the packing space not covered by the car.
Area not covered=Area of Parking Space - Area Covered by the Car
=153-96
=57 Square Feet
Answer:
15
Step-by-step explanation:
He has 3 numbers to choose from.
3
Then he has 5 letters to choose from.
Each of the numbers he chooses, can be paired to one of 5 letters.
3 * 5
Answer: 15
I.) (5x+3)/4-(2x-4)/3=5
Clear fractions:
3·((5x+3)/4)=15x+9
4·((2x-4)/3)=8x-16
15x+9-(8x-16)=5
15x+9-8x+16=5
Combine like terms:
7x+25=5
7x=-20
x=-20/7
II.) (3/11)·(5/6)-(9/12)·(4/3)+(5/13)·(6/15)
Remember PEMDAS
So first multiply:
3/11·5/6=15/66
9/12·4/3=3/3·1/1=3/3=1
5/13·6/15=1/13·6/3=6/39=2/13
(15/66)-1+(2/13)
Combine:
15/66-1/1=15/66-66/66=-51/66
-51/66+2/3=-51/66+44/66=-7/66
Answer: -7/66 :)
