Answer:
Option D : 32.15 square centimeters is the correct answer.
Step-by-step explanation:
Given that:
Area of the circle can be find by the following formula.
Area of circle = pi * radius * radius
The radius of circle in the given figure is 3.2 cm
Area of circle = 3.14 * 3.2 * 3.2
Area of circle = 32.1536 square centimeters
Rounding off to two decimal places.
Area = 32.15 square centimeters
Hence,
Option D : 32.15 square centimeters is the correct answer.
Answer:
mx = y
or
y = mx
Step-by-step explanation:
If she pays <em>m </em>per share, and <em>x</em> represents each share, you will multiply <em>m and x.</em><em> </em>If she sold all them for the value of <em>y.</em> Then you set <em>mx</em> equal to <em>y.</em>
<em />
mx = y
or
y = mx
Answer:
Your favorite radio station in a given year plays 105120 songs.
Step-by-step explanation:
Lets make some assumptions:
1. A radio program in average last 50 minutes, because 10 of them are for commercials.
2. a song average length is about 3 minutes
3. the speakers use 10 to 20 minutes of the radio program.
4. So, in an hour just 30 minutes are effectively used to play songs on a radio station. That results in 10 per hour at least, and 13.3 at most. So lets settle an average of 12 songs per hour.
5. The radio station plays songs 24 hours a day unstoppable.
Now:
A day has 24 hours, a week seven days and therefor (24*7= 168 hours) 168 hours in a week.
A year has 52.1429 weeks, so it has 8760 Hours (52.17429weeks*168hours=8760 hours )
So:
8760 hours in a year
12 songs per hour
We are given with the distances of the Frostburg Mall and <span>Sojourner Truth Park. we get first x which is the point in the axis of the city at which the line connecting the two places passes. the equation is 5 / x = 2/ (7-x ); x is equal to 5. hence the angle of elevation from the point of intersection to the places is 45 degrees. The distance from the park to the city *at intersection* is 5 sq.root of 2 while that at the mall is 2 sq.rt of 2. The total distance is 9.90 miles.</span>
