Question: I took a test that was worth 15 marks, I got 10.5 out of 15 on the test. The test was worth 20% of my final grade. How much % did I get out of the test?

14%

Step-by-step explanation:

final grade score=a

20% of a=15

20/100 x a=15

20a/100=15

Cross multiply

20a=15 x 100

20a=1500

Divide both sides by 20

20a/20=1500/20

a=75

B% of 75=10.5

B/100 x 75=10.5

75B/100=10.5

Cross multiply

75B=10.5 x 100

75B=1050

Divide both sides by 75

75B/75=1050/75

B=14

answer: 20

step-by-step explanation: subtract the minimum date value from the maximum data value to find the date range. in this casem the date range is 42 - 22 = 20

x = 25

step-by-step explanation:

a^2+b^2=c^2

7^2+24^2=c^2

49+576=625

sqrt625=25

x=25
