Answer:
π = C / d
Step-by-step explanation:
The circumference of a circle is given by the general formula;
C = 2 * π * r .... or C = π d (r = radius, d = diameter)
We can easily modify the second formula to isolate π in order to express the circumference in relation to the diameter:
π = C / d
To obtain π, you need to divide the circumference by the diameter.
We're used to think about the circumference in terms of radius... but since we deal with 2 * r * π and that 2 * r = d... it's also convenient to use the diameter.
The value of x would be 50 degrees because it is an acute angle, so hat would make sense. It would be 50 degrees because the internal degrees of a triangle add up to 180 so 180-80 equals 100, and since it is a isosceles triangle the two angles would be the same. 100 divided by 2 is 50
You combine like terms, if the variables are the same the just add the numbers in front of them.
Answer:
It would only take three hours.
Step-by-step explanation:
1/6+1/x=1/2
x + 6=3x
6=2x
x=3hr
