One third of the candidates for a job were 25 years old or younger. Two sevenths of the candidates were at least 50 years old.
If 84 people applied for the job, how many were between 25 and 50?
Which of the following is a factor of 450 and multiple of 25?
The formula h - 15 = 3.2t gives the height h in inches of a plant t weeks after planting.
Which is the rate at which the plant's height is increasing?
15 inches per week
18.2 inches per week
3.2 inches per week
48 inches per week
How high was the initial height of the shrub?
The formula h -15 = 3.2t gives the height h in inches of a plant t weeks after planting.
When was the height 31 inches?
Some time between 11 and 18 weeks
Some time between 7 and 12 weeks
Some time between 6 and 10 weeks
Some time between 3 and 7 weeks
3.2t = 16
t = 16÷3.2
t = 5
The height is 31 inches after 5 weeks
The next three questions refer to the following diagram:
A graph of the temperature T (degrees Fahrenheit) in a refrigerator t hours after midday.
What is the equation of the axis of symmetry of this graph?
T = 9
t = 3
T = 0
t = 0
Refer to the following diagram:
It is necessary to find the times when the temperature is 8o F. Which of the following is the correct equation to do this.
9 - t = 8
9 +t2 = 8
9 - t2 = 8
9t - t2 = 8
Which of the following is the equation of the straight line joining the points on the graph corresponding to t = 2 and t = 1?
T + 3t = 11
T - 3t = 11
T + 11t = 3
T + 3t = 1
The point on the graph corresponding to t = 2 is (2,5).
The slope of the straight line joining them is (5 - 8)÷(2 - 1) = -3.
The equation is T = -3t + c
As (2,5) lies the line we can substitute for t and T.
5 = -3×2 + c
c = 11
Equation is T = -3t + 11 which is the same as (a)
The following two questions relate to the sphere shown below:
The formula for the volume V of the sphere = 4(pi)r3 / 3.
Which of the following is the closest approximation to the volume when r, the radius, is 11 inches?
6000 cubic inches
5590 cubic inches
5573 cubic inches
5000 cubic inches
If the radius of the sphere were doubled by what factor would the surface area be enlarged?
Note: The formula for the surface area S of the sphere = 4 x (pi) x r2
