Answer:
X=15
all you have to do is subtract 3 from 18 to get x
Decimal : 1.5
Percent : 150%
Answer: 6 inch
Step-by-step explanation:
From the question, we are informed that a map of Rockbridge County has a scale factor of 2.5 in = 5 miles.
When the actual distance from Fairfield to Lexington is 12 miles, the distance on the map will be:
= 12/5 × 2.5
= 2.4 × 2.5
= 6 inch
Answer:
1:45 (one hour and 45 minutes)
Step-by-step explanation:
12:45 - 1:45 = 1 hr.
1:45 - 2:30 = 45 min.
Constant of Variation has this formula for Direct Variation.
y = kx
Where y = cost in dollars; x = length in meters; k = constant
We will use the formula for direct variation because the problem states that the cost varies directly to the length.
In the problem we need to get the constant of variation.
k = y/x
k = $4500 / 200 meter
k = $22.50 cost per meter.
A.) The equation relating C and s is:
k = C/s
* i just substituted C for y and s for x.
B.) The constant of variation represents the additional cost that the company will pay for every meter in length they add. which is $22.50 per meter.
C.) y = kx ; substitute C and s to y and x respectively;
C = ks
C = $22.50 * 700 m
C = $15,750
