Put the numbers in order from smallest to largest:
21,34,45,53,71,88
Since there are an even amount of numbers you must take the middle two and find the average(add them together then divide by 2)
45+53=98
98/2=49
Answer:
this answer is going to a 20 out of 100 percent
the answer is C or D
Answer:
23.7
Step-by-step explanation:
Ok first you have to figure out the amount of cans produced in a minute by the machines. So do 7200 divided by 200 and 7200 by 300 to get 36 Cans per minute on the new machine and 24 Cans per minute on the old one. So now we need to figure out an equation to figure out the amount of time needed to make 7200 cans with them working together which means addition. The equation will be 36x+24x=7200 which can be simplified to 60x=7200 and your answer for total amount of time will be in minutes. You should get 120 minutes.
(85 + 60) ÷ 2 = 72.5 Close to 71%
Answer: D - 71%
