Using the fundamental counting theorem, we have that:
648 different area codes are possible with this rule.There are 6,480,000,000 possible 10-digit phone numbers.The amount of possible phone numbers is greater than 400,000,000, thus, there are enough possible phone numbers.The fundamental counting principle states that if there are p ways to do a thing, and q ways to do another thing, and these two things are independent, there are ways to do both things.
For the area code:
8 options for the first digit.9 options for the second and third.Thus:
[tex]8 \times 9 \times 9 = 648[/tex]
648 different area codes are possible with this rule.
For the number of 10-digit phone numbers:
7 digits, each with 10 options.648 different area codes.Then
[tex]648 \times 10^7 = 6,480,000,000 [/tex]
There are 6,480,000,000 possible 10-digit phone numbers.
The amount of possible phone numbers is greater than 400,000,000, thus, there are enough possible phone numbers.

Answer:
On the Y axis
Step-by-step explanation:
Answer:
(0, 7)
Step-by-step explanation:
aight so its set up as (x,y). X on the graph is left and right while y is up and down. "8" means that the X is positive or to the right of the origin. If you go left, essentially you are subtracting. So 8-8=0. Same kind of idea for the Y axis. Up is positive, down is negative. If you're going down 6 from 13 (13-6) then you are at 7. (0,7)

What is the distance between the points (1,6) and (-7,3) on a standard coordinate plane?
39
73
173
55
Step-by-step explanation:
I think you are missing the square root signs or so in the answer options.
the distance between 2 points is calculated by using Pythagoras for right-angled triangles.
c² = a² + b²
c is the Hypotenuse of the triangle and the distance between the points, which are the end points of the Hypotenuse.
a and b are the legs and enclose the 90 degree angle. they are the differences of the x and y coordinates between the 2 points.
so,
distance² = (1 - -7)² + (6 - 3)² = 8² + 3² = 64+9 = 73
=>
distance = sqrt(73)

Solve for c. 2a + 3b = c
Please help as soon as possible. Thanks! =D
Answer:
a = c - 3b/2
Step-by-step explanation:
2a + 3b - 3b = c - 3b
2a = c - 3b
2a/2 = c/2 - 3b/2
therefore your answer is a = c - 3b/2

Student Council plans on selling fresh hamburgers at the homecoming game. They
bought 40 lbs of ground chuck to use to make burgers and each burger uses 0.25 lbs
of chuck to make. What is the most amount of burgers they can sell at the game

Student Council can make at the most 160 fresh burgers.
Step-by-step explanation:
Take 0.25 and divide it by 40.
0.25 / 40 = 160
addison and kelsey are running on a path modeled by x^2+y^2-10x-18y-378=0, where the distance is in meters. what is the maximum distance between the runners at any given time
The maximum distance between them is the diameter of the circle, which is of 44 units.
The equation of a circle of center [tex](x_0, y_0)[/tex] and radius r is given by:
[tex](x - x_0)^2 + (y - y_0)^2 = r^2[/tex]
The diameter is twice the radius, and is the maximum distance between two points on the same circle.
They are running on a circular path, modeled by:
[tex]x^2 + y^2 - 10x - 18y = 378[/tex]
Completing the squares, the equation is:
[tex](x - 5)^2 + (y - 9)^2 = 378 + 5^2 + 9^2[/tex]
[tex](x - 5)^2 + (y - 9)^2 = 378 + 25 + 81[/tex]
[tex](x - 5)^2 + (y - 9)^2 = 484[/tex]
Then, the radius is: [tex]\sqrt{484} = 22[/tex], which means that the maximum distance between the runners at any given time is of 44 units.

Answer:
-2/3 + 1/3 = -1/3
Step-by-step explanation:
using addition to solve a fraction with the same base
step 1: take the denominator of both fractions and clear them from the equation
ex: -2/3 + 1/3 = ? (-2 + 1 = ?)
step 2: solve the new equation -2 + 1 to get your answer of
ex: -2 + 1 = ? (-2 + 1 = -1)
step 3: since both denominators of the fractions have the same number then our answer will also have a denominator of 3 giving us the answer to the problem -2/3 + 1/3 = ? is -1/3

Step-by-step explanation:
There is no minimum to the number of cups she can purchase, thus x > 0 or x >= 1. The maximum amount she can purchase is x = 6 or x <= 6, thus 0 <= x <= 6. Plugging these two values into the function we get a range of 10 <= x <= 22.
