Answer: 7 cars
Step-by-step explanation: Since he earned 400$ a week and he had 1450$ by the end, subtract 1450-400 and you get 1050. You then divide 1050 by 150 (1050÷150) and you get 7, so he sold 7 cars
Answer:
weight * (4 / 5) = 30
weight * .8 = 30
weight = 30 / .8
weight = 37.5 pounds
Step-by-step explanation:
A fleet of nine taxis is to be dispatched to three airports in such a way that three go to airport A, five go to airport B, and one goes to airport C. In how many distinct ways can this be accomplished?
2.44) Refer to Exercise 2.43. Assume that taxis are allocated to airports at random.
a) If exactly one of the taxis is in need of repair, what is the probability that it is dispatched to airport C?
b) If exactly three of the taxis are in need of repair, what is the probability that every airport receives one of the taxis requiring repairs?
So, my answer to 2.44a is 1/9. Hopefully this is correct at least :)
For 2.44b, my guess was
(3C1)(1/3)(2/3)2 * (5C1)(1/3)(2/3)4 * 1/3
The solutions manual on chegg (which seems to be riddled with errors) says something completely different. Is my calculation correct?
The value of x can be found by adding the two angles and setting them equal to 180 because they are on a straight line.
3h + 18 + 15h = 180
18h + 18 = 180
18h = 162
h = 9
So the value of h is 9
Omar can make 14 whole dumplings. You change 2 3/4 cups to an improper fraction ( multiply the denominator and add the numerator ) and you get 11/4. Since you need 3/16 cups for one dumpling you have to find the greatest common denominator which is 16. You multiply 4 by 11 to get the numerator and end up with 44/16. Since you need 3/16 for one whole dumping you divide 44 by 3 and get 14.6 repeating. You cannot have a fraction of a dumpling so you round down and get the answer 14.
