The rate of the machine is 10 boxes per min.
Step-by-step explanation:
Given,
A machine can make 150 boxes in 15 min
To find the rate of the machine
Meaning to find the number of boxes machine it can make in 1 min
We will apply unitary method.
In 15 min it makes 150 boxes
In 1 min it makes (150÷15) boxes = 10 boxes
Hence the rate is 10 boxes per min.
Step-by-step explanation:
The total number of people mentioned in this problem is 15. 15 will be the denominator for the probability in fraction form. The sum of the # of people that include lifeguards and managers will be the numerator.
Therefore, the probability that the person picked is either a manager or a lifeguard is 10/15 [because there are 2 managers and 8 lifeguards; 2 + 8 =10].
<u>Fraction form of probability: 10/15</u>
<u>Decimal form: 0.6 repeated</u>
<u>Percent form: about 66.67%</u>
Answer:
B.
Step-by-step explanation:
You would mutiply 56.25 x 6 and 25.8 x 3 and get 337.5 + 77.4 and the final answer would be $414.9
