By definition, the area of a circle is given by:
Where,
r: radius of the circle.
Substituting the values in the given expression, we have:
Rounding to the nearest tenth we have:
Answer:

Answer:
(3) Jonah's graph has a steeper slope than Rowan's
Step-by-step explanation:
First we are going to write the equations for the amount of money that each one save
y = a+bx
Where y: Amount of money in the jar
a: Initial saving
b: Money saved every week ( graph's slope )
x: Number of week
Then, for Rowan
y = 50 + 5x
and for Jonah
y = 10 + 15x
Initially Rowan's graph lies above Jonah's graph but this situation change with time.
It is always true that Jonah's graph has a steeper slope than Rowan's, because for Rowan's graph the slope is 5 and for Jonah's graph the slope is 15
Then the answer is:
(3) Jonah's graph has a steeper slope than Rowan's
Answer:
m=60º
n=30º
Step-by-step explanation:
a triangle is 180º total
an equilateral triangle has all 60º angles
since the one symbol for a right angle is cut between two triangles you can say that the one angle in the equilateral triangle +n=90º
substituting the values 60+n=90
so n=30
Then since a triangle is 180º you can make an equation that says 180=90+m+n
again substituting 180=90+m+30
60=m
an easy way to check is 180=90+30+60 180=180
Answer:
= 
= 
you need to be consistant when setting up the proportions. The times always need to be on top and the days needs to always on bottom.
Cross multiply and solve for the variable.
20(30) = 5(m)
600 = 5m
120 = m
So, in 30 days the theatre showed 120 movies.
2*pi*R should be substituted in. 2*13*3 = 78
