Incorrect
Danny earned a total of 40($6.30) = $252. To find the number of hours Erica would take to earn $252, divide $252 by $8.40.

Question 2 of 30
2. Question
1 pointsΔABC is a right triangle and \overline{\rm CD} ⊥ \overline{\rm AB} . If the measure of ∠CAD = 40°, what is the measure of ∠DCB?
Correct
Incorrect
Since m∠ACB = 90° and m∠CAD = 40°, then m∠B = 180 − 90 − 40 = 50°. In BCD, m∠CDB = 90° and m∠B = 50°. Therefore,m∠DCB = 180 − 90 − 50 = 40.

1 pointsHenry has $5 more than Oliver, and the same amount of money as Murray. Together, they have $85. How much money does Oliver have?
Correct
Incorrect
Set up an equation with Oliver’s money as the unknown, and solve. Oliver = x, Henry = 5 + x, and Murray = 5 + x. Therefore,
x + 2(5 + x) = 85
x + 10 + 2x = 85
3x + 10 = 85
3x = 75
x = 25

Correct
Incorrect
Let x = m∠3 and 2x = m∠2 m∠1 + m∠2 + m∠3 = 180
36 + 2x + x = 180
3x + 36 = 180
3x = 180 − 36 = 144
x = 144 ÷ 3 = 48 degrees 
Question 20 of 30
20. Question
1 pointsMs. Klein bought 4 pounds of beef and 3(1/2) pounds of chicken for $13.98. If the beef cost $2.76 per pound, what was the cost of the chicken per pound?
Correct
Incorrect
The beef costs 4($2.76) = $11.04. The chicken costs $13.98 − $11.04 = $2.94. To find the cost per pound of chicken, divide $2.94 by 3 (1/2) or by 7/2, 2.94 ÷ 7/2 = 2.94 × 7/2 = 0.84.

Question 21 of 30
21. Question
1 pointsHow many dollars were spent for labor?
Correct
Incorrect
Forty percent of the total expenses of $240,000 went for labor: 0.40($240,000) = $96,000.

Question 22 of 30
22. Question
1 pointsThe distance between two heavenly bodies is 63,150,000,000 miles. What is the number expressed in scientific notation?
Correct
Incorrect
To express a number in scientific notation, express it as the product of a number between 1 and 10 and a power of 10. In this case, the number between 1 and 10 is 6.315. In going from 6.315 to 63,150,000,000, you move the decimal point 10 places to the right. Each such move represents multiplication by 10^{10} and 63,150,000,000 = 6.315 × 10^{10}

Question 23 of 30
23. Question
1 pointsWhat is the slope of the line passing through points A (5,4) and B (0,3)?
Correct
Incorrect

Question 24 of 30
24. Question
1 points1 kilometer =
Correct
Incorrect
1 km = 1,000 m and 1 m = 100 cm. So 1 km = 100,000 cm and 1 km = 1,000,000 mm.

Question 25 of 30
25. Question
1 pointsTo measure the distance (DC) across a pond, a surveyor takes points A and B so that \overline{\rm AB} is parallel to \overline{\rm DC} . If \overline{\rm AB} = 60 feet, \overline{\rm EB} = 48 feet, and \overline{\rm ED} = 80 feet, find \overline{\rm DC} .
Correct
Incorrect
Let x = DC. Since ΔABE is similar to ΔCED, the lengths of their corresponding sides are in proportion. (x/60 = 80/48) => 48x = 80(60) = 4,800 => x = 4,800 ÷ 48 = 100 =100 feet is the answer.

Question 26 of 30
26. Question
1 pointsThe graph shows what happens to each $100 taken in by a small business. How many dollars out of each $100 taken in represent profit?
Correct
Incorrect
Add the amounts given: 11 + 6 + 5 + 40 + 30 = $92. $100 − $92 leaves $8 for profit.

Question 27 of 30
27. Question
1 pointsNick scored 7 more points than Josh in a basketball game. Paul scored 2 points less than Josh in the same game. If the three boys scored a total of 38 points, how many points did Josh score?
Correct
Incorrect
Let x = number of points scored by Josh, x + 7 = number of points scored by Nick, and x − 2 = number of points scored by Paul.
x + x + 7 + x − 2 = 38
3x + 5 = 38
3x = 33
x = 11 
Question 28 of 30

1 pointsA box in the form of a rectangle solid has a square base 5 feet in length and a height of h feet. If the volume of the rectangular solid is 200 cubic feet, which of the following equations may be used to find h?
Correct
Incorrect
Use the formula V = lwh. In this case, l = 5, w = 5, and h = h. Therefore, V = 5 × 5 × h = 25h and 25h = 200.

Question 29 of 30
29. Question
1 pointsWhich point on the number line represents the closest approximation to the square root of 12?
Correct
Incorrect
Since 32 = 9 and 4² = 16, √12 is between 3 and 4. Only point D lies between 3 and 4.

Question 30 of 30
30. Question
1 pointsThe diagram represents a large living room. What is the area, in square yards, of the room?
Correct
Incorrect
Divide the floor space into two rectangles by drawing a line segment. The area of the large rectangle = 20 × 15 = 300 sq. ft. The area of the small rectangle = 10 × 15 = 150 sq. ft. The total area of floor space = 150 + 300 = 450 sq. ft. Since 9 sq. ft. = 1 sq. yd., 450 sq. ft. ÷ 9 = 50 sq. yd.
