To find the unit cost per tube of lip gloss, we divide the total cost by the number of tubes.
Total cost = $17.28
Number of tubes = 24
Unit cost per tube = Total cost / Number of tubes
Unit cost per tube = $17.28 / 24
Unit cost per tube = $0.72
Therefore, the unit cost per tube of lip gloss is $0.72.
Answer: D. $0.72
The base of a shipping drum is in the shape of a circle with a diameter of 22 inches. Which of the following is closest to the circumference of the base of the shipping drum? (Use 3.14 for .)
A.
1,519.76 inches
B.
34.54 inches
C.
69.08 inches
D.
138.16 inches
The circumference of a circle is found using the formula C = πd, where C is the circumference and d is the diameter.
Given that the diameter of the circle is 22 inches, we can calculate the circumference as follows:
C = 3.14 * 22
C ≈ 69.08 inches
Therefore, the closest value to the circumference of the base of the shipping drum is 69.08 inches.
Answer: C. 69.08 inches
Which of the following is equivalent to the fraction above? - (4/13)
A. -4/-13
B. 4/13
C. -13/4
D. -4/13
The fraction - (4/13) can be simplified by multiplying both the numerator and denominator by -1 to give us 4/13.
Therefore, the equivalent fraction to - (4/13) is B. 4/13
Answer: B. 4/13
Which equation could be used to find the total amount earned, T, for working h hours at d dollars per hour?
A. t=dh
B. t=h/d
C. t=d/h
D. t=d+h
The equation that could be used to find the total amount earned, T, for working h hours at d dollars per hour is:
T = d * h
Therefore, the correct equation is A. t = dh.
Answer: A. t = dh.
e probability of randomly selecting a nickel from a bag of 50 coins is 25/50. Which of the following describes the likelihood of selecting a nickel?
A.
neither unlikely nor likely
B.
unlikely
C.
likely
The probability of randomly selecting a nickel from a bag of 50 coins is 25/50, which simplifies to 1/2.
Since the probability is exactly 1/2, it means that selecting a nickel from the bag is equally likely as not selecting a nickel.
Therefore, the correct option is:
A. neither unlikely nor likely
Answer: A. neither unlikely nor likely
