Answer:
2232.48 meters
Step-by-step explanation:
From the diagram:
Radius of semicircle = 74
Length of straightway on each side = 1000
The length of school track :
Straightway on each side = 2 * 1000 m = 2000m
Length of semicircle = πr/2
Length of both semicircle = 2 * 3.142 * 74 /2 = 232.47785
Total Length = ( 2000 + 232.47785) = 2232.48 meters
If the student got 123 marks and failed by 39, your first step would be to add the two together, getting 162. This is the amount of marks needed to pass the test.
You would then divide 162 by .36 (.36 is equivalent to 36%). This would result in a maximum of 450 marks.
The maximum marks on this test are 450 marks.
2x + 3y = 12
2x - y = 4
4y = 8
y = 2
2x - 2 = 4
2x = 6
x = 3
The coordinates are (3,2) and that is your answer :)
An absolute value cannot equal a negative number. So c, if it was a negative number, would have no solution.
You're looking for the percent, so your equation would be:
x% × 200 = 0.5
(x/100) × 200 = 0.5
2x = 0.5
x = 0.25
So, 0.25% of 200 is 0.5.
* You can check your work by multiplying 0.25% × 200. Surely enough, it does give you 0.5.
Answer = 0.25%
