NO.307 Determine which of the choices best solves the problem shown in the first picture and then mark the corresponding choice on your answer sheet. The problem is presented in the first drawing and the remaining four drawings are possible solutions.

NO.308 There are 12 liters of a mixture of acetone in alcohol that is 33 % acetone. 1 low many liters of alcohol must be added to the mixture to reduce it to a mixture containing 25% acetone?

If the original mixture is 33 % (or 1/3) acetone, then 1/3 of the mixture of 12 liters, or 4 liters, is acetone.
The fraction 4/12 represents the ratio of acetone to total mixture. If the total mixture is increased by x liters, the ratio of acetone to total mixture becomes 4/(12+x).This is to be equal to 25% (or 1/4).
4 / 12+x = 1 / 4
To undo the divisions on both sides of the equation, multiply both sides by 4 and also by 12+x.
4/12+x * 4(12+x)/1
= 1/4 * 4(12+x)/1
16 = 12+x
The isolate x on one side of the equation, subtract 12 from both sides 16-12 = 12 + x-12 4=x

NO.309 Although they last no longer than a fraction of a second, voltage variations can cause problems with sensitive electronic equipment. Variation in voltage causes digital clocks to blink and timers to be thrown off schedule.
Computers are especially

useful when you transfer data to memory.

easy to protect from variations in voltage.

useful in publishing.

sensitive to voltage variations.

The paragraph talks about the effect of voltage variations on sensitive equipment. It is logical tC.nclude that computers, which are also sensitive equipment, would be affected by voltage variation.

NO.310 What are the major layers of Earth’s atmosphere in order from the Earth’s surface upward?

Troposphere, stratosphere, mesosphere, thermosphere, exo sphere

Troposphere, stratosphere, ionosphere, exo sphere

Troposphere, tropopause, ionosphere, stratosphere, exo sphere

Meso sphere, stratosphere, troposphere, tropopause

The fivemajorlayers of the atmosphere from the Earth’s surface upward are the troposphere, stratosphere, mesosphere, thermosphere, and exosphere. Thetropospherestarts at the Earth’s surface and extends to between 23,000 ft (7 km) at the poles and 60,000 ft (17 km) at the equator, with some variations due to weather factors. Thestratosphereextends from the top of the troposphere (23,000- 60,000 ft or 7-17 km) to about 160,000 ft (60 km). Thestratospherecontains theozone layer,which is mainly located in the lower part of the stratosphere from about 50,000-115,000 ft (15-35 km) above the surface, although the thickness varies somewhat across both the seasons and the Earth’s geographical regions. Themesosphereextends from about 160,000 ft (50 km) to about 265,000-285,000 ft (50-54 miles or 80-85 km). This is also where most meteors bum up when entering the atmosphere

NO.311 DNA, a nucleic acid contained in all living material, orders every cell to reproduce in a certain manner. In feet, DNA molecules determine both the form and function of all living cells.
DNA is

found only in animals.

one kind of cell.

a nucleic acid.

a nuclear device.

The feet that DNA is a nucleic acid is stated in the first sentence. Answers A, B, and D are all incorrect details.

NO.312 The safest way to make a hole in sheet metal is to:

burn it with a soldering iron

cut it using snips

punch it using a metal punch

get someone else to do it

NO.313 Determine which of the choices best solves the problem shown in the first picture and then mark the corresponding choice on your answer sheet. The problem is presented in the first drawing and the remaining four drawings are possible solutions.

NO.314 The proportioning valve in a hydraulic brake system

reduces pressure to the front brakes.

controls the brake warning switch.

is used only on drum-type brake systems.

reduces pressure to the rear brakes.

A proportioning valve is commonly used on a vehicle equipped with front disc and rear drum-type brakes.
The valve reduces hydraulic pressure to the rear drum brakes to prevent rear wheel lockup and skidding during heavy brake pedal application.

NO.315 Determine which of the choices best solves the problem shown in the first picture and then mark the corresponding choice on your answer sheet. The problem is presented in the first drawing and the remaining four drawings are possible solutions.

NO.316 The three important properties of sound waves are:

wavelength, speed, and crest

speed, frequency, and reflection

wavelength, frequency, and vibration

wavelength, frequency, and speed

NO.317 Which weight exerts more pull on the horizontal bar from which both weights hang by strings as shown?

Block A.

Block B.

Both exert the same pull.

Insufficient information to solve this problem.

The string holding the 10-lb. weight exerts more pull on the bar. The fact that that string is longer does not change how much tension is on it due to the weight at its end.

NO.318

In the figure shown above, the board holds the weight of the cat. The board is placed on two identical scales. Each scale reads:

The 20-pound cat and the 4-pound board weigh 24 pounds total or, divided by 2, 12 pounds per scale.
