(18x^5yz) /(6xyz^4)
Simplify the expression above. Which of the following is correct?
A. (3x^4)/z^3
B. (3x^4y)/z^3
C. 3x^4z^3
D. 3x^4yz^3 - Answer A. (3x^4)/z^3
(18x^5yz) /(6xyz^4)
=3 x4 (y becomes 0 since y^1 -y^1 = 0) z^1 -z^4 = z^-3 or 1/z^3
3x^4z^-3 or (3x^4)/z^-3
7x - 6 = 3x -26

A. -5
B. 8
C. -8
D. 5 - Answer A. -5
7x - 6 = 3x -26

4x = -20
x=-5
,A bakery sells three varieties of muffins . On a recent morning , the bakery sold 41 blueberry muffins , 27
bananas nut muffins and 20 bread muffins . Estimate the total number of muffins sold . - Answer
90
41 = 40
27 = 30
20 = 20
40 + 30 +20 = 90 estimated (actual is 88 which still rounds to 90)
A cell is placed in a hypertonic solution. Which of the following describes the resulting osmosis?
A. There is a net flow of water out of the cell.
B. There is a net flow of water into the cell.
C. The net flow of water into and out of the cell is zero.
D. There is no flow of water. - Answer A. There is a net flow of water out of the cell.
water can enter and exit the cell due to osmosis (a type of diffusion from high water area to low water
area)
in hypertonic solution the inside of the cell is more salty compared too the environment meaning more
water inside the cell compared to outside so water goes from high to low so from inside cell to outside
A family is planning a driving vacation and is estimating the cost of gasoline . While on vacation , the
family plans to drive 3,000 miles . The car goes about 25 miles per gallon , and the cost of gasoline is $
1.66 per gallon . Which of the following is the estimate for the cost if the gasoline for gasoline for the
vacation ?
A. $72.29
B. $199.20
C. $41.50
D. $120.00 - Answer B. $199.20
3,000 miles / x = 25 miles / 1 gallon (cross multiply) = 120 gallons
$1.66/1 gallon = x/120 gallons (cross multiply) = 199.2
A farmer needs to buy fertilizer for his farmland. The instructions on the fertilizer say 49.5 pounds of
fertilizer is needed for 1 acre of land. The farmer buys 2,000 pounds of fertilizer.
What is the approximate number of acres he can cover with the fertilizer he bought?
A. 125
,B. 1000
C. 300
D. 40 - Answer D. 40
49.5 pounds / 1 acre = 2,000 pounds / x (cross multiply) =
40 acres
A garden in the shape of a square has an area of 13 square feet . Each side of the garden has a length of
√13 feet . Which of the following is the decimal approximation for the length of each side?
A. 3.6 feet

C. 6.5 feet
D. 2.6 feet - Answer A. 3.6 feet
√13 =3.6
A girl and her dog are playing tug of war with a piece of rope . The girl pulls on the rope with a force of
165 newtons ( N ) towards the east . The dog pulls with a force of 190 N toward the west . What is the
net force on the rope?
A. 25 N towards the west
B. 35 N towards the east
C. 190 N towards the west
D. 165 N towards the east - Answer A. 25 N towards the west
190-165 = 25 and more towards west since 190 is west
A lab scale weighs 3 pounds, 5 ounces. Which of the following is the scale's weight in (oz)?
A. 53 oz
B. 35 oz
C. 41 oz
D. 29 oz - Answer A. 53 oz
1 pound = 16 oz
3 Ib / 1 Ib = x/16 oz (cross multiply) = 48 oz
48 oz + 5 oz = 53 oz
A local law school reports that 74% of last year's graduates are employed by law firms, 3% work for the
government, and 2% work for nonprofit organizations. The rest of the graduates work at jobs unrelated
, to law. based on these outcomes, which of the following is the percentage of graduates working job
unrelated to Law?
a. 79%
b. 69%
c. 21%
d. 5% - Answer c. 21%
74 +3 +2 =79% working for law
100-79 = 21% not working in law
A mutation of a portion of a DNA molecule changed the resulting mRNA sequence from AUU-GGG-UUC
to CUU-GGG-UUC. Using the table, predict the resulting amino acid sequence.
A. From Met-Gly-Leu to Leu-Gly-Phe
B. From Leu-Gly-Phe to Met-Gly-Leu
C. From lle-Gly-Ser to Leu-Gly-Phe
D. From lle-Gly-Phe to Leu-Gly-Phe - Answer D. From lle-Gly-Phe to Leu-Gly-Phe
A patient drives 19 miles one way to medical facility for treatment. How far does the patient drive round
trip in 22 days of treatment?
A. 418 miles
B. 1,254 miles
C. 1,672 miles
D. 836 miles - Answer 19 miles one way
19 miles back
19+19 = 38 miles round trip
38 miles times 22 days = 836 miles
A patient's temperature is recorded in degrees Fahrenheit every hour for 8 hr . the temperature in
Fahrenheit were 99.0 , 99.2 , 98.7 , 99.3 , 99.7 , 98.6 , 100.0 , and 99.0 . What is the median temperature
? - Answer 99.1 * F
98.6 , 98.7, 99.0, 99.0, 99.2, 99.3, 99.7, 100
99.0 +99.2 = 198.2
198. = 99.1 is median
