Answer:
43
Step-by-step explanation:
All the even numbers have a factor of 2, so we can eliminate 56 and 34. 75 ends in a 5, so that cannot be a prime number (ending in 5 is a multiple of 5). The sum of the digits of 63 (6+3) is 9, and that is divisible by 3, so that number is also not prime. 43 is a prime number.
Answer:
28.258mm
Step-by-step explanation:
A semi circle is half of a circle, so we will divide it by 2 after finding the area.
Formula for finding semi circle = pi x radius ÷ 2
Formula for radius = diameter ÷ 2
Radius = 36 ÷ 2 = 18mm
Semi circle = 3.14 or 22/7 x 18 = 56.57
56.57 ÷ 2 = 28.285
Note: I don't have a calculator with me right now, so you might want to consider typing out pi x 18 ÷ 2 on a calculator since my answer might be wrong because the answer has endless decimals.
Answer:
What
Step-by-step explanation:
Hello!
The average mean (arithmetic mean) of all the multiples of ten from 10 to 190 inclusive would be C. 100.
Explanation:
10 and 190 inclusive would mean that there are 19 terms.
To find the arithmetic mean, we must add all the numbers and divide by the amount of numbers.
If you add up all the terms, you will get 1,900. Now, divide that by the number of terms.
1,900 ÷ 19 = 100
Therefore, your answer is C. 100.
Have a wonderful day!
