Answer: 35
Step-by-step explanation:
Given : A bag contains four red marbles, two green ones, one lavender one, three yellows, and one orange marble.
Total = 4+2+1+3+1=11
To find sets of four marbles include none of the red ones, we need to exclude red marbles when we count the total number of marbles.
Then, the total marbles(exclude red) =11-4=7
Now, the combination of 7 marbles taking 4 at a time is given by :-
Hence, the number of sets of four marbles include none of the red ones = 35
In order to divide integers, the first thing to check is the sign:
- When dividing two positive integers, the result will be a positive integer.
- When dividing two negative integers, the result will be a positive integer.
- When dividing integers with different signs (one negative and one positive), the result will be a negative integer.
Then, after checking the sign, we need to calculate the value of the division.
Some examples of divisions are:
In the first division, the result is 3, because we have that 8 * 3 is equal 24.
Also, both numbers are positive, so the result is also a positive number.
In the second division, the result is -3, because 5 * (-3) is equal -15.
The result is negative, because the two numbers have different signs.
In the third division, the result is 10, because -10 * 10 is equal -100.
The result is positive, because both numbers are negative.
Answer:
27in
Step-by-step explanation:
So, perimeter means we add all the sides together, as opposed to area, where we multiply them together.
9 - 5 = 4.
So the perimeter of the triangle would be:
3+4+=12
5 + 5 + 4 +1 (the 1 is from 4 -3) = 15
15 + 12 = 27
