Answer:
The fraction that eats in the cafeteria is 2/3
Step-by-step explanation:
To find this, start by taking the number of students and subtracting the amount that bring their lunch.
18 - 6 = 12 that eat in the cafeteria.
Now that we have that number, divide by the total number of students.
12/18
To simplify this fraction, divide both numbers by 6.
2/3
How to solve exponents:
Learn the correct words and vocabulary for exponent problems. When you have an exponent, like 2^{3}, you have two simple parts. The bottom number, here a 2, is the base. The number it is raised to, here a 3, is known as the exponent or power. If you are talking about 2^{3}, you would say it is "two to the third," "two to the third power," or "two raised to the third power."
If a number is raised to the second power, like 5^{2}, you can also say that the number is squared, such as "five squared."
If a number is raised to the third power, like 10^{3}, you can also say it is cubed, such as "ten cubed."
If a number has no exponent shown, like a simple 4, it is technically to the first power and can be rewritten as 4^{1}.
If the exponent is 0, and a "non-zero number" is raised to the "zero power", then the whole thing equals 1, such as 4^{0}=1 or even something like (3/8)^{0}=1
Answer:
Step-by-step explanation:
distance PQ=√[(0-0)²+(2+11)²]=√13²=13
distance AB=√[(-3-0)²+(-4-0)²]=√(9+16)=√25=√5
distance CD=√[(0-8)²+(-6-0)²]=√(64+36)=√100=10
