#1 is A #2 is A
Step-by-step explanation:
Answer:
As it ایس the correct answer is 45
78
7.90
4 significant figures.
we can start counting the numbers after all the zeros in front. the zeros in front doesn't count in. but the zeros after the first number that is 1 or larger counts.
therefore we only need to look at 3010
Answer:
Step-by-step explanation:
Given Annabella time for a race is 24.2 seconds, if another runnee's time was 6.43 seconds faster, then the time taken for another runnee's time will be 24.2 - 6.43 = 17.77secs.
Let a variable X be the difference between annabelle's time and the other runners time.
X = annabelle's time - other runners time.
X = 24.2 - (24.2 - 6.43)
X = 24.2-24.2+6.43
X = 6.43seconds
Hence the expression between annabelle's time and the other runners time is X = 24.2 - (24.2 - 6.43)
<em>The difference between annabelle's time and the other runners time is 6.43seconds</em>
Not impressed that you consider yourself "too lazy" to at least get started on the solution of this problem. Why not "give it the old college try?"
Start by choosing letters to represent the unit cost of each popcorn and drink:
p: popcorn, d: drink.
Then 2p + 3d = $22.25 and 12p+4d=$39.00
Note that the unit of measurement of all 6 terms here is " $ ".
Solve this system of linear equations simultaneously:
2p + 3d = $22.25
12p+4d=$39.00
In your shoes I would mult. the first equation by -6 and then combine the result with the second equation. p will temporarily disappear, and you'll be left with an equation in d only, enabling you to find the unit cost of a drink.
Come on. Show your stuff. You'll need to respond through Comments.
