Answer:
r = 2.55
Step-by-step explanation:
The formula for finding the radius of a circle using the area is r = √A/π
with the r being the radius. the A being the area, and the π being pi (we'll use 3.14).
So the equation should look like this:
r = √(20.4/3.14)
Find the quotient of 20.4/3.14 and round to the nearest tenth
r = √6.5
Find the square root and round to the nearest hundredth
r = 2.55
x = hours
car 1 left an hour before car 2 so you have 55(x+1)
car 2 = 75x
add them together to equal miles driven:
55(x+1) + 75x = 380
55x+55 + 75x = 380
combine like terms:
130x+55 = 380
subtract 55 from each side:
130x = 325
divide both sides by 130
x = 325 /130 = 2.5
x = 2.5 hours
so 2.5 hours
Answer:
the value of x is 115
