Nearest hundred is 300 anything 50 and above rounds up and below 50 it rounds down
Answer:
x = (ab - ac )/c
Step-by-step explanation:
x/a = b/c - 1 Multiply through by ac:
cx = ab - ac Divide both sides by c:
x = (ab - ac )/c.
First you can convert 45 miles per hour to feet per hour:
45 × 5,280 = 237,600 feet per hour
Now you must remember that there are 60 minutes in an hour, and 60 seconds in a minute. So you can divide 237,600 feet per hour by 60 to get feet per minute:
237,600 ÷ 60 = 3,960 feet per minute
Now you just have to divide 3,960 by 60 again to get feet per second:
3,960 ÷ 60 = 66 feet per second
Now you know how fast the car can travel (in feet) in a second. So to work out how many feet it travels in 3 seconds, you just have to multiply 66 by 3:
66 × 3 = 198 feet
Therefore your final answer is <em>198 feet</em> :)
Using proportions, it is found that the length of the drawing is of 2.583 feet.
---------------
- Scale problems are solved using proportions, by a rule of three.
- The length of the front is of 155 feet.
- The drawing has a scale of 1/60 of the actual size, that is, each actual feet is worth 1/60 on the drawing.
Thus:
1 feet - 1/60 feet
155 feet - x
Applying cross multiplication:
The length of the drawing is of 2.583 feet.
