Mike's Toy Truck Company manufactures two models of toy trucks, a standard model and a deluxe model. Each standard model requires 2 hours ( $\mathrm{hr}$ ) for painting and 3 hr for detail work; each deluxe model requires 3 hr for painting and 4 hr for detail work. Two painters and three detail workers are employed by the company, and each works 40 hr per week.
a) Using $x$ to denote the number of standard-model trucks and $y$ to denote the number of deluxe-model trucks,write a system of linear inequalities that describes the possible number of each model of truck that can be manufactured in a week.
(b) Graph the system and label the corner points.

A lightning flash is seen in the sky and 8.2 s later the boom of the thunder is heard. The temperature of the air is $12^{\circ} \mathrm{C}$ (a) What is the speed of sound at that temperature? [Hint: Light is an electromagnetic wave that travels at a speed of $3.00 \times 10^{8} \mathrm{m} / \mathrm{s} .1$ (b) How far away is the lightning strike?

Pipe organs have a set of pipes with different lengths. With those different pipes, organs can produce sounds over a wide range of frequencies. If the frequency range is from 31.3 Hz to 1.58kHz, then what is the shortest wavelength of sound the organ can produce? vsound = 343m/s
What is the longest wavelength the organ can produce?

A baseball pitcher throws the ball in a motion where there is rotation of the forearm about the elbow joint as well as other movements. If the linear velocity of the ball relative to the elbow joint is 10.0 m/s at a distance of 0.500 m from the joint and the moment of inertia of the forearm is 0.5 kg·m2, what is the rotational kinetic energy of the forearm?

Male Gorillas can be classified into three groups:
The alpha males who dominate the pack;
The beta males consisting mainly of the younger animals who are still learning the ropes; and
The gamma males made up of the older males and others who have lost the plot.
A zoo is planning to establish a colony of gorillas and is considering the relative numbers of each type that should be allowed.
Let x,y
and z
be the number of alpha, beta and gamma males respectively. Experience has shown that the number of alpha males should be equal to one fifth of the sum of beta and gamma males. Solve this system in terms of a parameter t.
