The Self-Transcendence 3,100 mile race is the world's longest certified footrace. The equation 3100=50x can be used to determine how many miles a person has to run each day, x, if they complete the race in 50
days.
How many miles does a person have to run each day, if they complete the race in 50 days?
Answers
Answer: 62 miles per day
Step-by-step explanation:
3100 = 50x
3100/50 = 50x/50
62 = x
A person has to run 62 miles each day to complete the Self Transcendence 3,100-mile race in 50 days.
What is an expression?In mathematics, expression is defined as the relationship of numbers, variables, and functions using mathematical signs such as addition, subtraction, multiplication, and division.
To find out how many miles a person has to run each day, we need to solve the equation:
3100 = 50x
Dividing both sides by 50, we get:
62 = x
Therefore, a person has to run 62 miles each day to complete the Self-Transcendence 3,100-mile race in 50 days.

Find 250% of 18. Show your work or explain how you arrived at your answer.
Please keep the explanation simple
Answers
Answer: 45
100% of 18 = 18
50% of 18 = 9
18 + 18 = 36 = 200%
36 + 9 = 45 = 250%
:)
Answer: 45
Step-by-step explanation:
To find a percentage of a number, like what we're being asked to do, you multiply the number ( 18 in this case ) with the decimal form of the percentage. So, since we know 100% is equal to 1, 150% is equal to 1.5 and so on, 250% must be equal to 2.5. Since we know this, we now do:
2.5 x 18 = 45.
You must read 130 pages for homework. Reading at the same rate as the previous question, can you complete the assignment in two hours?
Answers
Answer:
No.
Step-by-step explanation:
It isn't possible to read 130 pages for homework in 2 hours because like the previous question says, you are only able to tead 52 pages per hour. Now 52 multiplied by 2 is only equal to 104 pages read in two hours. This means that you will have left 26 pages unread for your homework. Although, you are able to read 130 pages in 2 and a half hours since for two hours you are able to read 104 pages, and the left over pages (26 pages) is half of 52 pages which is our hourly rate, meaning that every half hour, we are able to read 26 pages!

What is the cosine rule?The cosine rule is a mathematical formula used in trigonometry to determine the lengths of sides of a triangle, given the lengths of two sides and the measure of the angle between them. The cosine rule states that the square of the length of a side of a triangle is equal to the sum of the squares of the lengths of the other two sides, minus twice the product of the lengths of those sides and the cosine of the angle between them.
c^2 = a^2 + b^2 - 2abCos C
7^2 = 5^2 + 8^2 - 2(5 *8) Cos C
49 = 25 + 64 - 80 CosC
-40 = -80 CosC
Cos C = 0.5
C = 60°
b^2 = a^2 + c^2 - 2ac Cos B
5^2 = 8^2 + 7^2 - 2(8 *7) Cos B
25 = 64 + 49 - 112Cos B
Cos B = 38
C = 180 - (60 + 38)
A = 82

These are the following solutions to the given question related to integers, irrational numbers, and whole numbers, (a) False, (b) True (c) False (d) True.
By question,
(a) Some whole numbers are not integers = False. We know that every whole number is an integer. The set of whole numbers includes all positive integers (1, 2, 3, ...∞) and zero (0).
(b) Some integers are not irrational numbers = True. The numbers (a) that cannot be expressed as a fraction of two integers and have non-terminating decimal expansions, non-repeating are known as Irrational numbers. Integers, on the other hand, are whole numbers and zero.
(c) Some whole numbers are irrational numbers. = False. The subset of integers are Whole numbers, and they are always rational. They can be expressed in a fraction with a denominator of 1.
(d) All integers are whole numbers. = True. Integers include all the whole numbers i.e. positive, negative, and zero. So, every integer is also a whole number.
