Answer:
1) 3/4
2) 15 days
Step-by-step explanation:
A has completed 3/12 = 1/4 of the work
3/4 of the work is left to be done
B can do the work in 20 days.
Since 3/4 of the work is left,
He needs (3/4)×20 = 15 days to complete the remaining work
For an outdoor event organizers, the expected number of people who will attend is 32700
<u>SOLUTION:</u>
Given, For an outdoor event organizers estimate that 60000 people will attend if it is not raining.
And If it is raining, event organizers estimate that 21000 people will attend.
On the day of the show, meteorologists predicted a 70% chance of rain.
We have to determine the expected number of people who will attend.
Now, number of people = 70% of rain case + 30% of other case.
Number of people = 0.7 x rain case + 0.3 x other case
Number of people = 0.7 x 21000 + 0.3 x 60000
= 2100 x 7 + 6000 x 3 = 32700.
Hence, the expected count is 32700
I think there would be 50 because if you put them to gather
It has 3 zeroes which are

Hope this helped!

Answer:
17.11 meters
Step-by-step explanation:
You are using trigonometry in this problem.
The height of the flagpole represents the side <u><em>opposite</em></u> the given angle.
The base of the triangle is given as 19 meters and represents the side <u><em>adjacent</em></u> to the given angle.
Out of the main trigonomentric functions (sine, cosine, and tangent), only tangent uses both the opposite and adjacent sides.
Tan(angle) = opposite / adjacent
If we plug in what we know into that equation: <em>tan(42 degrees) = h / 19</em>
This means that <em>your answer = 19 * tan(42) = 17.11</em> meters
