Answer: Its 3/1000
Step-by-step explanation:
Put 0.003 over 1 0.003/1 x 1000/1000 = 3/1000
Answer:
35%
Step-by-step explanation:
% of guests who attended the wedding is number of guests who attended the wedding divided by the number of invited guests and the result multiplied by 100%
Therefore
28/80 x 100%
0.35 x 100%
35%
35% of the invited guests attended the wedding

(x-9)(x-9)
6 is 25% of 24. 6 times 4 = 24
Answer:
54.2 mph
Step-by-step explanation:
Since the drivers leave at the same time and travel in directions 90° from each other, their separation speed can be found using the Pythagorean theorem. Let c represent Cynthia's average speed. Then (c-10) will represent Tim's average speed. Their combined separation speed is 70 miles per hour, so we can write ...
70² = c² +(c -10)²
4900 = 2c² -20c +100 . . . . eliminate parentheses
c² -10c -2400 = 0 . . . . . . . . divide by 2; put in standard form
(c -5)² -2425 = 0 . . . . . . . . . rearrange to vertex form
c = 5 ±5√97 . . . . . . . . . . . . solve for c, simplify radical
c ≈ 54.244 ≈ 54.2 . . . . . . . use the positive solution
Cynthia's average speed was 54.2 miles per hour.
