Answer:
A) a sphere with a radius of 2 unit
or
B) a sphere with a diameter
Step-by-step explanation:
if the given circle gives you the radius, the answer is a, if it gives you the diameter, the answer is b
Answer:
The length of GH is also 12 because JH is the perpendicular bisector of GI which means both segments are divided exactly in half, so GH=HI so GH=12 which means HI=12. Hope that helps:)
Step-by-step explanation:
It would take 500 minutes for the cost to be $21.50.

Linear equation</h3>
A linear equation is in the form:
y = mx + b
where y, x are variables, m is the rate of change (slope) and b is the y intercept.
Let y represent the cell phone bill for x minutes. Using points (230, 17.45) and (370, 19.55):
![y-y_1=\frac{y_2-y_1}{x_2-x_1} (x-x_1)\\\\y-17.45=\frac{19.55-17.45}{370-230} (x - 230)\\\\y=0.015x+14](https://tex.z-dn.net/?f=y-y_1%3D%5Cfrac%7By_2-y_1%7D%7Bx_2-x_1%7D%20%28x-x_1%29%5C%5C%5C%5Cy-17.45%3D%5Cfrac%7B19.55-17.45%7D%7B370-230%7D%20%28x%20-%20230%29%5C%5C%5C%5Cy%3D0.015x%2B14)
For 150 minutes:
y = 0.015(150) + 14 = 16.25
For $21.50:
21.50 = 0.015x + 14
x = 500
It would take 500 minutes for the cost to be $21.50.

Answer:
Faris' arrival time = 3:30 pm + 3 h 54 mnt = 7:24 pm
Step-by-step explanation:
Driving distance between Manchester to London = 195 miles
Coach left Manchester = 3.30 pm
Average speed of coach = 50 mph
Total time taken by the coach to reach the Manchester to London = 195÷50 = 3.9 h
0.9 h = 0.9×60 mnt = 54 mnt
Now,
3.9 h = 3 h 54 mnt
Hence Faris' arrival time in London = 3.30 pm + 3 h 54 mnt = 7.24 pm
Answer: The answer would be B. 12a+6b
