Answer:
Rons costs less by 4 dollars
Step-by-step explanation:
Sams
y = 15x+25
x=3
y = 15*3+25
= 45+25
=70
Rons
Using averaging
for 3 hours Add 2 and 4 hours and divide by 2
(49+ 83) / 2 = 132/2= 66
Rons costs less by
70-66 =4
The correct answer is Line ST I think I’m not sure
Answer: The radius of this circle is 0.5
Step-by-step explanation:
We have a circle that passes through the point (0, 0.5)
We do not know the center of the circle, so we have infinite possible radius to answer this, but let's suppose that the center of the circle is in the point (0, 0)
For a circle centered in the origin, we have the equation:
x^2 + y^2 = r^2
Where r is the radius.
Here we have that x = 0 and y = 0.5
then:
0^2 + (0.5)^2 = r^2
0.5^2 = r^2
r = 0.5
The radius of this circle is 0.5
l=51
m=78
n=51
n and l have the same value since it’s an isosceles triangle, so that’s why I doubled 4x-9
