Suppose the number of laps = m
According to the question, each lap of 25 yards is covered 3 seconds faster than the previous one, so the series become
x , x-3 , x-6 , x-9, ............................
25 * m = 200
m = 
m = 8
As m is the number of laps, and each lap is 3 second faster.
So 8 laps will be 8*3 = 24 seconds faster.
Answer:
644,262 copies
Step-by-step explanation:
Since this is a proportion problem, and we are given three values and one variable which is the total number of copies sold to date (x). Then we can use the Rule of Three to solve this problem. To do this we simply multiply the diagonal values and divide by the last value which would give us the value of the variable x
39,300 copies <======> 6.1%
x copies <=======> 100%
(100*39,300) / 6.1 = 644,262 copies
Therefore, a total of 644,262 copies have been sold to date.
Answer:
-15 and 1
Step-by-step explanation:
Multiply numerators which is 2 times 5. Don't forget that 14 can be written as 14/1 so you would also multiply 2 times 5 by 14. Then you would multiply the denominators which is 3 times 6 times 1. So you're answer is 140/18 (5x2x14/3x6x1).
Answer:
One angle is 26 degrees and the other is 64 degrees.
Step-by-step explanation:
Complementary angles add up to a total of 90 degrees. Therefore, if one of the two angles is known to be 38 degrees less, then the other angle can be calculated:
90 = (x-38) + (x)
52 = 2x
26 = x
This means that one of the angles is 26 degrees, and the other is 64 degrees.
