Sector = theta/360° × pi×radius×radius
40/360×22/7×10×10
4/36×22/7×100
1/9×22/7×100
22/63×100
2200/63=34.92 sq feets (approximately)
Option C is the answer . Don't get confused with decimals as maybe the person who provided these options used pi =3.14 instead of what i used i.e. =22/7.
It should be B. The dash-line triangle is half the size of the solid-lined triangle. You can find the scale factor by finding the ratio between the side lengths of the two triangles. The scale factor in this case is 2 because you are reducing thr solid-lined triangle by one half. If you are reducing by a fraction, it means that you are enlarging be the reciprical of the fraction. As reducing implies division and dividing a fraction is equivalent to multiplying by the reciprical. Thus the correct answer is B.
Answer:
The independent is the weight of all the people already on the elevator and the dependent variable is the weight of the elevator after you get on.
You can multiply each fraction on both top and bottom so that they have 24 as the denominator. The equation becomes
subtract 16/24 to both sides and you get
now subtract 20/24 from both sides and
<u />
multiply 24 on both sides
-26=21m
and divide by 21 on both sides
m=-26/21 or -1.24
Answer:
12 teams.
Step-by-step explanation:
Let B represent number of Blue division teams and R represent number of Red division teams.
We have been given that blue division cost 160 per team, so cost of B blue division teams would be .
We are also told that red division cost 180 per team, so cost of R Red division teams would be .
Since volleyball league organizer organizer collects $2,040 from both divisions of volleyball team, so we can represent this information in an equation as:
Since it is a league match, so both divisions must have equal teams. This means .
Upon substituting this value in our equation, we will get:
Since the number of teams is blue division is equal to teams in red division, therefore, 12 teams will play in game.
