Answer:
Therefore the ratio of home-team fan to away team fan at 8:00 p.m is
=109:67
Step-by-step explanation:
Initially , total home team fans =1000
and away team fans = 700.
7:00 pm to 8:00 pm = 1 hour = 60 minutes
Given that
Every 10 minutes the number of arrival home team fans is 15.
Then in 1 minutes the number of arrival home team fans is
and in 60 minutes the number of arrival home team fans is
=90
Therefore total home team fans = (90+1000)=1090
Given that
Every 10 minutes 5 fans leave of away team leave.
then in 1 minutes fans leave of away team leave.
and In 60 minutes =30 fans leave of away team leave.
Since 30 away team fans leave.
Total away team fans = (700-30)=670
Therefore the ratio of home-team fan to away team fan at 8:00 p.m is
=1090:670
=109:67
Answer:
1. 121 π unit²
2. 143°
3. 151 unit²
Step-by-step explanation:
1.
Area of a circle is given by the formula A = πr²
where
A is the area,
r is the radius of the circle
From the given diagram, we can see that the radius is 11, hence the area will be:
The answer is units^2
2.
The unshaded secctor and the shaded sector equals the circle. We know that circle is 360°. The unshaded sector has an angle of 217°. So the shaded part will be 360 - 217 = 143°
The measure of the central angle of the shaded sector is 143°
3.
Area of a sector is given by the formula
Where
is the central angle of the sector (in our case it is 143°)
r is the radius (which is 11)
Plugging in all the info into the formula we have:
<em>rounding to the nearest whole number, it is </em>151 units^2
