B is 18 cards
C is 16 cards
Step-by-step explanation:
Answer:
3x - 12 is an expression equivalent to 3(x - 4)
Explanation:
Another way to write this expression is to simplify it. To simplify the given expression, multiply the number three by the x and negative four inside the parentheses.
3(x - 4)
3x - 12
Therefore, 3x - 12 is the simplified version of the expression 3(x - 4). In other words, 3x - 12 is an expression equivalent to 3(x - 4).
Answer:
The first 4 guests can arrive in 32,760 ways.
Step-by-step explanation:
The order in which the guests arrive is important. For example, A,B,C,D is a different outcome to B,A,C,D. So we use the permutations formula to solve this question.
Permutations formula:
The number of possible permutations of x elements from a set of n elements is given by the following formula:

In this question:
4 guests from a set of 15. So

The first 4 guests can arrive in 32,760 ways.
Whats the question tell me and i'll try to help
1. To solve this problem, you must aplpy the formula for calculate the volume of a sphere, which is:
V=4/3(πr)
V is the volume of the sphere.
r is the radius of the sphere.
2. You must calculate the radiius. You have that the beach <span>ball has a diameter of 18 inches, then:
r=diametert/2
r=18 inches/2
r=9 inches
3. When you substitute r= 9 inches into the formula, you obtain:
</span><span>
V=4/3(πr)
V=3053.62 inches</span>³
