Answer:
85 parking spaces
Step-by-step explanation:
Given that :
Parking spaces on floors :
Let first floor = x
Second floor = 2x
Third floor = 2x + 3
Total parking spaces = 428
THEREFORE ;
x + 2x + 2x + 3 = 428
5x + 3 = 428
5x = 428 - 3
5x = 425
x = 425 / 5
x = 85
Hence, there are 85 parking spaces on the first floor
Answer:
Step-by-step explanation:
<u>Use the formula:</u>
- degrees/360° = L/circumference
- or
- radians/π = L/circumference
<u>As per given:</u>
l = 12 feet, r = 10 feet
- degrees = 360°*12/(2*3.14*10) = 68.78°
- radians = π rad *12/(2π*10) = 0.6 rad
Mass=Density*Volume
Density=1.1 g/cc
Volume of a cylinder: <span>π*r^2*h
</span>Radius of the top of the can: 3.57
Volume of this can: 480.47
480.47*1.1=528.517
If I'm correct the mass of this can should be 528.517
Answer:
y=2x+3
Step-by-step explanation:
1/5 (x - 8) = x - 16...distribute thru the parenthesis
1/5x - 8/5 = x - 16 ...multiply everything by common denominator of 5
x - 8 = 5x - 80 ...subtract 5x from both sides
x - 5x - 8 = - 80 ...add 8 to both sides
x - 5x = -80 + 8 ...combine like terms
-4x = - 72 ...divide both sides by -4
x = -72/-4
x = 18
