Answer: The maximum the average can be for all the guests at the birthday party is 2 minutes 57 seconds.
Step-by-step explanation:
Since the ratio of adults to children is 4:1, then it follows that:
4/5 of the people are children
1/5 of the people are adults
A weighed average of the times would give:
1 minute 25 seconds = 85 seconds [for 1/5 of the people (the adults)]
3 minutes 20 seconds = 200 seconds [for 4/5 of the people (the children)]
(85 x 1/5) + (200 x 4/5) = 177 seconds
Therefore, the maximum the average can be for all the guests at the birthday party is 2 mins 57 secs.
Answer:
81
Step-by-step explanation:
Given
x² - 18x = 29
To complete the square
add ( half the coefficient of the x- term )² to both sides
x² + 2(- 9)x + (- 9)² = 29 + (- 9)²
x² + 2(- 9)x + 81 = 29 + 81
(x - 9)² = 110
Take 305.5 and divide it by 100 and you'll get your answer
