Answer:
314 cm²
Step-by-step explanation:
It's not the point O, but the circle O, a point has no area.
The area of a circle is given by the formula A = π r²
We don't have r (radius), but we have the diameter, which is double the radius. So, r = d / 2 = 20 cm / 2 = 10 cm
Now, we can plug r directly into the equation:
A = π r² = π 10² = 100π = 314 cm²
The answer is B : the square root of 25 is 5, because 5x5=25.
So it's 18-5....
Hope I helped :)
Angles in a 4-sided shape = 360 degrees
2x + x + 101 + 85 = 360
3x + 186 = 360
3x = 174
x = 58 degrees
Answer:
Linear function
Explanation:
Given the scattered plot in the attached image.
We want to identify the type of function that can best model the given scattered plot.
The scattered point as shown in the attached image form a straight line, So, the best type of function that can best model it is a linear function (straight-line graph).
20+2x=3x subtract 2x from both sides
20=x after 20 miles the total cost for both companies will be the same
PROOF
20+2(20)=3(20)
20+40=60
60=60
