Answer:
15 kilometres
Step-by-step explanation:
Based on the wording of your question, I am assuming you already know that Paul ran 250 metres every 1 minute, and that the ratio is 250:1. To get the second part of the answer, convert metres to kilometres. 0.001*250= 0.25. Paul ran 0.25 kilometres per minute. The ratio of kilometres per minute is 0.25:1. Next, convert minutes to hours. Multiply the entire ratio by 60, as there are 60 minutes in an hour. The ratio of kilometeres per minute is 15:60, and the ratio of kilometres per hour is 15:1, meaning Paul ran 15 kilometres in one hour.
Answer:
72
Step-by-step explanation:
you multiply 36 *2 therefore giving you 72centimeters squared
Answer:
n = 2
Step-by-step explanation:
Here, we want to write the simplified form of the equation given in the question.
Firstly, we write the equation in an equation form:
4/5n -1/5 = 2/5n
5n(4/5n -1/5) = 2/5n(5n)
(4/5n * 5n) -(1/5)(5n) = 2
4- n = 2
n =4-2
n = 2
The answer is: -11/3
8/4 * 11/-6
Multiplying an odd number of negative terms makes the product negative
-8/4 * 11/6
Reduce the numbers with the greatest common factor
-2 * 11/6
2 cancels out -2; divide 6 by 2
= -11/3
A chord and a radius form an equilateral triangle.
The area of the larger segment is:
A = 5/6 r² π + r²√3/2 = 5/6 · 64 · 3.14 + 32 · 1.73 =
= 167.47 + 55.36 = 222.83 in²
