This is a problem of fundamental counting principle. In a
sequence of events, the total possible number of ways all events can performed
is the product of the possible number of ways each individual event can be
performed. So here there is one car in each place so there 4 possible
cars to get the 1st place, 3 possible car for the 2nd
place, 2 possible cars for 3rd place and 1 for the 4th
place. The 4x3x2x1 = 24 different order
Answer:
A) 12, 35, 40
Step-by-step explanation:
To identify a Pythagorean Triple, it has to go into the Pythagorean Theorem.
The formula is A^2 + B^2 = C^2
The first two numbers of your options would be the A^2 and B^2. Once you have that value, you can take the square root of C and that gives you what C^2 would be.
For instance:
12^2 + 35^2 = 1,369. The square root of 1,369 is 37. So A) is not correct.
What is the question? Do you mean "At the beginning of the month a store had the balance of $554"? If so, what is the question?
For this case we have the following number:
What we must do is rewrite the number as the product of two numbers.
We have then:
From here, we write the number as the multiplication of a whole number and a power of base ten.
We have then:
Where,
: whole number
: power of base 10
Answer:
The distance written as a whole number multiplied by a power of ten is:
Answer: 17 patients stayed for longer than 10 minutes.
Step-by-step explanation:
Let x represent the number of patients that stayed for longer than 10 minutes.
The doctor charges $21.80 for consultations that last less than 10 minutes and $27.50 for those that last longer than 10 minutes. Yesterday the doctor earned $1077.90. If 28 consultations lasted less than 10 minutes, it means that
28 × 21.80 + x × 27.50 = 1077.90
610.4 + 27.5x = 1077.9
27.5x = 1077.9 - 610.4
27.5x = 467.5
x = 467.5/27.5
x = 17
