You do 80km/1hr = n/3.75
Use this proportion to find that n=300
So, he drives 800km.
Answer:
\[y=-5x+18\]
Step-by-step explanation:
Given that the line is parallel to \[y = -5x + 6\]
Hence the slope of the line is given by -5
Hence the equation of the required line can be represented by \[y = -5x + c\]
This line passes through (4,-2). Substituting:
\[-2 = -5 * 4 + c\]
=> \[-2 = -20 + c\]
=> c = 20-2 = 18
So the required equation of the line is given by : \[y = -5x + 18\]
From the given options, option 3 is the correct one.
Answer: $142.5
Step-by-step explanation: If the price is being marked up by 50%, you take 50% or half of the original price of $95, which is 47.5, and add it to your original price.
95 + 47.5 = 142.5
Answer:
11 yards
Step-by-step explanation:
The volume of a cone formula is:

Where V is the volume,
r is the radius (half of diameter)
h is the height
Given,
h = 15
V = 475.17
We find the radius (r) first by substituting given values:

The radius (r) is 5.5 yards
We need the diameter, which is DOUBLE THE RADIUS, so diameter would be:
Diameter = 5.5 * 2 = 11 yards
