You make a proportion. 400/54=x/1
multiply across:
400x=54
Divide by 400:
x=54/400
Answer= 0.135 seconds per meter

janet obtained 32% for her statistics test, which was out of a total of 300 marks. how much should she score in the computer sci
vesna_86 [32]

Her score in computer to get a proportionally weighted average of 46% will be 134.

The total score for both subjects = 200 + 300 = 500

Since the proportionally weighted average is 46%, then her score will be:

= 46% × 500

= 0.46 × 500

= 230

Since she had 32% for her statistics test, which was out of a total of 300. Her score will be:

= 32% × 300

= 0.32 × 300

= 96

Therefore, her score in computer will be:

= 230 - 96

= 134

Well how long is the ribbon? I'm not asking for the dollar amount, I will answer your question if you can tell me the length of the ribbon. No one can figure it out unless you give the total length.
