This isn't as hard as it looks.
The ratio is 1 to 12.
You just have to multiply the model value by 12.
12 x 5.4 = 64.8 feet. Now, the answer has to be in yards, so divide by 3.
64.8 div 3 = 21.6 feet.
Answer:
x = ±sqrt(2)
Step-by-step explanation:
8x^2 - 5 = 11
Add 5 to each side
8x^2 - 5+5 = 11+5
8x^2 = 16
Divide each side by 8
8x^2 = 16/8
x^2 = 2
Take the square root of each side
sqrt(x^2) = ±sqrt(2)
x = ±sqrt(2)
Answer:
≈ 1.8 km
Step-by-step explanation:
150*5= 750 revs total
d= 2.5 ft
C=πd= 2.5*3.14= 7.85 ft
Distance= 7.85*750= 5887.5 ft ≈ 1.8 km
You have to convert the fraction so the bottom number is 100
1900: 14/25=56/100
1910: 29/50=58/100
1920: 53/100
1930: 13/20= 65/100
1940: 3/5=60/100
Your answer would be 1930: 13/20= 60/100
