The area of a circle is A = r^2pi
Since the area is equal to 121pi the equation would be, 121pi = r^2. To find r in terms of pi take the square root of 121, to find the radius. Then multiply that by two to get the diameter.
We are given equations y =3.5x and y=25x +40.50.
Where x represent time in hours and y represents cost in dollars.
We need to determine that which equation is not the equation of a proportional relationship?
In first equation we have slope 3.5 and y-intercept 0.
In second equation, we have slope 25 and y-intercept 40.50.
<em>In order to have a a proportional relationship, there should be y-intercept =0.</em>
<h3>Therefore, y= 25x + 40.50 is not the equation of a proportional relationship.</h3>
Oh girl idek. What grade is this
Answer:
option 4 = 25
Step-by-step explanation:
given= chord js and hL intersects at poimt p
to find = value of x
solution:according to the therom;
if the line extensions of the chordJS and HL INTERSECTS at point K then their lenghts satisfy
JK×KS=HK×KL
10×30=X×12
300=12x
300/12=x
25= x
7 5 35
-- X -- = -----
1 6 6
hope it helps
7 =7/1
Multiplying Fractions is easy . numerator times numerator and denominator times denominator. then simplify if possible
