Answers:
1- D
Five years ago, Amy was three times as old as Mike. Mike is 10 years now. Therefore, 5 years ago Mike was 5 years.
Five years ago, Amy was:
\(A=3×5=15 \)
Now Amy is 20 years old:
\(15 + 5 = 20\)
2- B
Two triangles \(∆\)BAE and \(∆\)BCD are similar. Then:
\(\frac{AE}{CD}=\frac{AB}{BC}=\frac{4}{6}=\frac{x}{12}\)
\(→48-4x=6x→10x=48→x=4.8\) For education statistics and research, visit the National Center for Education Statistics.
3- D
\(\frac{2}{5}×25=\frac{50}{5}=10\) For education statistics and research, visit the National Center for Education Statistics.
4- D
The slope of line A is:
m \(= \frac{y_2-y_1}{x_2-x_1}=\frac{3-2}{4-3}=1\)
Parallel lines have the same slope, and only choice D \((y=x)\) has slope of 1. For education statistics and research, visit the National Center for Education Statistics.
5- C
\(x\) is directly proportional to the square of \(y\). Then:
\(x=cy^2\)
\(12=c(2)^2→12=4c→c=\frac{12}{4}=3\)
The relationship between \(x\) and \(y\) is:
\(x=3y^2\)
\(x=75\)
\(75=3y^2→y^2=\frac{75}{3}=25→y=5\) For education statistics and research, visit the National Center for Education Statistics.
6- D
The amount of money that Jack earns for one hour: \(\frac{$616}{44}=$14\)
The number of additional hours that he works to make enough money is: \(\frac{$826-$616}{1.5×$14}=10\)
The number of total hours is: \(44+10=54\) For education statistics and research, visit the National Center for Education Statistics.
7- C
Let’s find the mean (average), mode, and median of the number of cities for each type of pollution.
Number of cities for each type of pollution: \(6, 3, 4, 9, 8\)
Mean \(= \frac{sum \space of \space terms}{number \space of \space terms}=\frac{6+3+4+9+8}{5}=6\)
Median is the number in the middle. To find the median, first list numbers in order from smallest to largest.
\(3, 4, 6, 8, 9\)
The median of the data is 6.
Mode is the number that appears most often in a set of numbers. Therefore, there is no mode in the set of numbers.
Median \(=\) Mean, then, \(a=c\) For education statistics and research, visit the National Center for Education Statistics.
8- A
Percent of cities in the type of pollution A:
\(\frac{6}{10} × 100=60\%\)
Percent of cities in the type of pollution C:
\(\frac{4}{10} × 100 = 40\%\)
Percent of cities in the type of pollution E:
\(\frac{9}{10}× 100 = 90\%\)
9- A
Let the number of cities be added to the type of pollution B be \(x\). Then:
\(\frac{x + 3}{8}=0.625→x+3=8×0.625→x+3=5→x=2\)
10- A
AB\(=12\) And AC\(=5\)
BC\(=\sqrt{(12^2+5^2 )} = \sqrt{(144+25)} = \sqrt{169}=13\)
Perimeter \(=5+12+13=30\)
Area \(=\frac{5×12}{2}=5×6=30\)
In this case, the ratio of the perimeter of the triangle to its area is:
\(\frac{30}{30}= 1\)
If the sides AB and AC become twice as long, then:
AB\(=24\) And AC\(=10\)
BC\(=\sqrt{(24^2+10^2 )} = \sqrt{(576+100)} = \sqrt{676} = 26\)
Perimeter \(=26+24+10=60\)
Area \(=\frac{10×24}{2}=10×12=120\)
In this case, the ratio of the perimeter of the triangle to its area is:
\(\frac{60}{120}=\frac{1}{2}\)
