The numbers of choices in each category are multiplied together. We assume the order of paint choices matters: using color 1 in area A and color 2 in area B is not the same as using color 2 in area A and color 1 in area B.

P(7,2)*4*3*2 = 42*4*3*2 = 1008 ways

_____
P(n, k) = n!/(n-k)!
P(7, 2) = 7*6 = 42

Two types of memberships are available for a theme park:
sergiy2304 [10]

The equation 2v-41=0 can be used to find the number of visits that would make two memberships cost the same amount.

Step-by-step explanation:

Given,

Per month charges of type 1 = $86

Per visit charge = $3

Let,

v be the number of visits.

T(v) = 3v+86    

Per month charges of type 2 = $45

Per visit charge = $5

P(v) = 5v+45

For same amount to be charged;

T(v) = P(v)

3v+86=5v+45\\86-45=5v-3v\\41=2v\\2v-41=0

The equation 2v-41=0 can be used to find the number of visits that would make two memberships cost the same amount.

Find the volume for the regular pyramid.<br><br><br><br> V =
mylen [45]
The volume is given by:
 V = L * Apb * h
 Where,
 L: side of the base
 Apb: apothema of the base
 h: height
 Substituting we have:
 V = (4) * ((root (3) / 2) * 4) * (6)
 Rewriting we have:
 V = (4) * ((root (3) / 2) * 4) * (6)
 V = 96 * (root (3) / 2)
 V = 48 * root (3)
 Answer:
 
V = 48 * root (3)

By the Triangle Inequality Theorem, if two sides of a triangle have lengths of 6 and 13, what are the possible lengths of the th
murzikaleks [220]
1. You have that two sides of a triangle have lengths of 6 and 13. Then, by the <span>Triangle Inequality Theorem, you have:

 a+b>c
 a+c>b
 b+c>a

 3. Therefore, you have:

 a=6
 b=13

 c<a+b
 c<6+13
 c<19

 4. The difference between a and b should be lesser that c. Then

 a-b<c
 13-6<c
 7<c

 5. Therefore:

 c=x

 7<x<19

 The correct answer is the option B: </span> B. 7<x<19<span>
