Answer:
Shaquille O'Neal's height= 2,160,000,000 nm
= 2.16 × 10^9 nm
Completed question;
The basketball player Shaquille O'Neal is 7 feet 1 inch tall, which is equivalent to 216 centimeters a nanometer (nm) is a unit of measurement that is one-billionth of a meter, convert his height to nanometers.
Step-by-step explanation:
Given;
Shaquille O'Neal's height= 216cm = 216 × 1/100 m = 2.16m
Since, a nanometer (nm) is a unit of measurement that is one-billionth of a meter.
1 m = 1 billion nanometers
So,
2.16m = 2.16 billion nm = 2160000000 nm
Shaquille O'Neal's height= 2160000000 nm
= 2.16 × 10^9 nm
Answer:
y = x + 3
Step-by-step explanation:
y = mx + b
m = slope
b = y-intercept
1x is the same as x
Answer:
Step-by-step explanation:
This is a Combination (as in permutation vs combination) question the symbol (n r) refers to "n choose r". This is sometimes written as nCr
i.e the question is asking you to find how many combinations each will yield when you chose r items from n item without repetition and order does not matter.
I will only do the first question for you and you can just follow the same steps to solve the rest of the questions.
Recall that
Consider question a) we are given (5 1) or ₅C₁
we can see that n = 5 and r = 1
If we substitute this into the formula:
₅C₁ = (5!) / [ (1!)(5- 1)!]
= (5!) / [ (5- 1)!]
= (5!) / (4!)
= (5·4·3·2·1) / (4·3·2·1)
= 5
hence ₅C₁ = 5
Answer:
Difference = 250 students
Step-by-step explanation:
Let the total number of students be x.
Given the following data;
% driving = 30%
% riding = 60%
% walking = 10%
Number of students driving = 375
First of all, we would determine the total number of students.
Total = 30/100 * x = 375
0.3x = 375
Total, x = 375/0.3
Total, x = 1250 students.
Next, we determine the number of students walking;
Walking = 10/100 * 1250
Walking = 12500/100
Walking = 125 students
Finally, we would determine many more students drive to school than walk to school;
Difference = 375 - 125
Difference = 250 students
