How many 5 number zip codes can be created if the first number cannot be one, three, or five, and each of the numbers must be different? (Hint: It may be helpful to list out the digits first.)
Answers
Answer:
21,168
Step-by-step explanation:
Given:
Available digits: 0, 1, 2, 3, 4, 5, 6, 7, 8, 9 (10 digits)Restrictions: first number can only be 0, 2, 4, 6, 7, 8, 9 (7 digits)Each of the 5 numbers must be differentTherefore:
1st number: 0, 2, 4, 6, 7, 8, 9 (7 digits)2nd number: 0, 1, 2, 3, 4, 5, 6, 7, 8, 9 (10 digits)3rd number: 0, 1, 2, 3, 4, 5, 6, 7, 8, 9 (10 digits)4th number: 0, 1, 2, 3, 4, 5, 6, 7, 8, 9 (10 digits)5th number: 0, 1, 2, 3, 4, 5, 6, 7, 8, 9 (10 digits)As each of the numbers must be different, the choices are:
1st number: 7 choices2nd number: 10 - 1 = 9 choices(since we can't repeat the 1st number)3rd number: 10 - 2 = 8 choices
(since we can't repeat the 1st and 2nd numbers)4th number: 10 - 3 = 7 choices
(since we can't repeat the 1st, 2nd & 3rd numbers)5th number: 10 - 4 = 6 choices
(since we can't repeat the 1st, 2nd, 3rd & 4th numbers)
Therefore, the total number of combinations is:
7 × 9 × 8 × 7 × 6 = 21,168

PYTHAGOREAN THEOREM
Answers
Answer:
8. 20.8 units
9. isosceles
Step-by-step explanation:
8.The vertical altitude line divides the triangle into two congruent right triangles. Each has a horizontal leg of 4 units, and a vertical leg of 5 units. (You can find these lengths by subtracting coordinates, or by counting grid squares.)
slant sides
The hpotenuses of these right triangles are the short sides (PR, QR) of the larger triangle PQR. We can find their length using the Pythagorean theorem. Defining S as point (-2, -1), we have ...
PS² +SR² = PR² . . . . . . . . . . . . the Pythagorean theorem relation
4² +5² = PR² = 16 +25 = 41 . . . with numbers filled in
PR = √41 . . . . . . . . . . . . . . take the square root
PR ≈ 6.4 . . . . . . . . . . . round to tenths
horizontal side
The length of side PQ is 8 units, found by subtracting x coordinates ((2 -(-6)) = 8), by counting grid squares, or by doubling the length of PS (2(4) = 8).
perimeter
The perimeter of the triangle is the sum of its side lengths:
perimter = PR +QR +PQ = 6.4 +6.4 +8 = 20.8
The perimter of triangle PQR is 20.8 units.
__
9.Sides PR and QR are congruent, so the triangle is isosceles.
_____
Additional comment
A triangle whose vertices are integer grid coordinates cannot be equilateral.

The number of sandwiches sold is 73. This is because it is multiplied by the expression for the money received per sandwich.
The cost to make each sandwich is S. This is stated in the first sentence of the problem.
The profit is 0.2S. This is because they sell each sandwich for an additional 20% of the cost ( S )
The amount of money the band receives is (S + 0.2S ). This is because it is the price per sandwich.

Employing a ruler or metric tape, Ally can determine the length of 8 inches of string.
What is the length?A length is a unit used to describe the measurement of a possession or a distance. It can be quantified in terms of inches, hands, yards, millimeters, meters, and miles, among other quantities.
Ally needs to apply the idea of assessing in order to determine the proper length of the string. Somebody can measure the measurement of the string with a ruler. If she doesn't have a ruler, she is able to measure the length of the required thread against an object of a string following: she already knows is a specific length, like one foot, for example.
To determine the length, the woman is able to determine the number of times the segment of string slips into the length that she wants string.

Step-by-step explanation:
Actually, for this equation to be true, m must be 4, as if a + b = c, then c - b is equal to a and vice versa. Here’s an example: If 1 + 2 = 3, then 3 - 2 = 1 and 3 - 1 = 2. So you see, 12 - 8 is equal to 4.

40.5 in²
Step-by-step explanation:
It's pretty easy if you find the surface area of each and every shape alone first.
I see 2 squares and 4 rectangles.
Let's start by finding the surface area of the squares:
-The formula to finding the area of a square is length x length.
L×L
1.5 in x 1.5 in= 2.25 in²
2.25 in is the surface area of 1 square
but we have two squares so you do 2.25 in × 2 to get the surface area of both squares.
2.25 in² × 2= 4.5 in² (this is the surface area of both squares)
Now we calculate the surface area of the four rectangles.
Formula: L×W (length × width)
6 in × 1.5 in = 9 in² (s.a of one rectangle)
Since we have four rectangles, we'll have to multiply it by 4
9 in² × 4= 36 in²
Now we add the total surface areas of both the squares and the rectangles.
4.5 in² + 36 in²= 40.5 in²
