Answer:

The answer is "19 inches and 60 inches".

Step-by-step explanation:

Throughout this question, the choices were missing that's why its correct solution can be defined as follows:

The formula for diameter= d=2r 

The formula for circumference = C=2\pi r  

let the r=9.5 so, the diameter and the circumference are:

\to d= 2 r= 2\times 9.5 =19\\\\\to C= 2 \pi r= 2\times \frac{22}{7} \times 9.5 =59.71 \approx 60 \\\\

It costs $12 to enter the fair and $0.50 per ticket for rides. How much total would you spend if you paid admission and bought 7
shepuryov [24]

The initial cost is $12 to enter.

Each ticket is $.50

we want to find out how much it costs for 70 tickets so we multiply the cost by the amount;

70 x .50 = 35

Therefor including the entry fee, it would cost $35 + $12

Which is $47

I hope this helps! :)

Find mean, median and mode of 140, 130, 90, 80, 60, 50, 30, 20, 10, 0
Alecsey [184]
For the mean you would have to add up all the numbers up and divide by the amount of numbers. For your problem you would get 610/10= 61. 

For the median you would arrange all the numbers in order from least to greatest and cancel one from the left and one from the right each time. Since there is no middle number, the closest would be 50 and 60. Thus you you add 50+60 and get 110 and then divide by 2 giving you 55.

For the mode, there is no mode because none of the numbers repeat more than once.

I hope this clarifies your doubt. :)
