Cross multiplying:-
18*x = 12*30
x = 360 / 18
x = 20 answer
The number 12 is missing in the data set.
<u>Step-by-step explanation</u>:
- The numbers are 9,12,16,18,23.
- The missing number is assumed to be 'x'
Mean = Sum of the integers / Total number of integers.
15 = (9+12+16+18+23+x) / 6
15 = (78+x) / 6
90 = 78+x
x = 90-78
x = 12
Answer: <em>1575 miles</em>
Step-by-step explanation:
<em>Let's take what we are given</em>
<em>35 miles an hour</em>
<em>45 hours</em>
<em>Let's now multiply them together to get our result</em>
<em>35x45</em>
<em>1575 miles in 45 hours</em>
Answer:
(7/12)*pi
Step-by-step explanation:
ACD/circumference = [35*pi/180]/2pi
<=>
ACD/[2*pi*3] = [35*pi/180]/2pi
The answer is 35 because since AC/DC is 90 degrees subtract ACB to get 35 for BCD
