Answer:
12 machines
Step-by-step explanation:
The production rate per machine is 1240/20 = 62
For 1,984 printers it would take 32 machines (1984/62 = 32)
32 needed minus the 20 they already have means they need 12 more machines.
The answer is 25%
(1)
If 64 is 100%, 48 is how much percent:
64 : 100% = 48 : x
x = 100% * 48 : 64
x = 75
(2)
Percent of decrease is:
100% - x = 100% - 75% = 25%
Answer: C
Step-by-step explanation: a^2 + b^2 = c^2
A. 6^2 + 8^2 = 10^2
B. 12^2 + 35^2 = 37^2
C. 4^2 + 6^2 does not equal 10^2.....(16 + 36 = 52 10^2 = 100)
D. 10^2 + 24^2 = 26^2
Answer:
C. Yes, because the ratios are equivalent between each pair of values.
Step-by-step explanation:
A relationship between two quantities is proportional if the ratio of the two quantities are the same for all the given possible pairs of values.
In the table given, the ratio of block to mins in the first given pair of values is 3/6 = 3/6 = ½.
In the second given pair, it is 7 to 14 = 7/14 = ½. The same ratio is gotten for the others as well.
Therefore, the table represents a proportional relationship.
The answer is: "C. Yes, because the ratios are equivalent between each pair of values."
