Answer:
D. 4
Step-by-step explanation:
Percent of drivers who wear seat belts = 68
Percent of drivers who do not wear seat belts = 100 - 68 = 32
Now, we know that for every 100 pull overs, 32 drivers will not be wearing belt.
32 drivers without seat-belt = 100 pullovers
1 driver without seat-belt = 100/32 pullovers
1 driver without seat-belt = 3.125 pullovers (4 pullovers)
So, a police officer should expect 4 pullovers until she finds a driver not wearing a seat-belt.
The linear function that models the relationship is P = 28,200 + 1950t.
<h3>What is the
linear function that models the relationship?</h3>
A linear function is a function that has a single variable raised to the power of 1. An example is x + 2
The first step is to determine the rate of increase in the population:
Rate of increase = (population in 2012 - population in 2008) / number of years
(36.000 - 28,200) / 4 = 1950
P = 28,200 + 1950t

Answer:25
Step-by-step explanation:
divide 75 by 6 then multiply by 2
An isosceles triangle is a special type of triangle that has two equal sides. Consequently, the two base angles are also equal. Since the interior angles of a triangle should sum up to 180°, the general equation should be
180° = 2*Base angle + Vertex angle
Let the base angle be x. Thus, the vertex angle is equal to
Vertex angle = 4x - 6
Substituting,
180 = 2x + 4x - 6
x = 31°
Vertex angle = 4(31°) - 6
Vertex angle = 118°
The formula to find speed:
We first need to find the distance to gift store:
18/60 × 10
=3miles
We can then find the time he used down hill:
3÷30×60
=0.1×60
=6 minutes
In total he walked:
3x2
=6miles
We can then find his average speed by dividing the distance by total time used:
=6÷(6+18)/60
=6÷24/60
=15mph
The answer is 15mph.
Hope it helps!
