Answer:
z = 
Step-by-step explanation:
Given that z is directly proportional to x³ and inversely proportional to y²
Then the equation relating them is
z =
← k is the constant of proportionality
Answer:
28%
Step-by-step explanation:
Here is the missing table from the question:
Speed (mph) Number of Vehicles
36-40 2
41-45 14
46-50 18
51-55 12
56-60 4
Given: A police officer records the speeds of vehicles on a road.
Now, finding the percent of vehicles traveling between 41 and 45 miles per hour.
First, calculating the total number of vehicles.
Total vehicles= 
Vehicles travelling at speed of 41-45 mph= 14
Formula; percent of vehicles traveling between 41 and 45 mph= 
⇒ Percent of vehicles traveling between 41-45 mph= 
∴ Percent of vehicles traveling between 41-45 mph is 28%
Answer:
D
Step-by-step explanation:
Answer:
S= 36.76
Step-by-step explanation:
S = area of base +(base of perimeter*Slant height)*1/2
S = 4*4+((4+4+4)/2)*3.46
S = 16+((12/2)*3.46)
S = 16+6*3.46
S = 16 + 20.76
S = 36.76 cm^2
