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:
There are 7340032 zipcodes that can be created without one, three, or five, as the first number.
Step-by-step explanation:
First you need to find the numbers in the first slot. The numbers could be 2,4,6,7,8,9, or 0. That is 7 numbers that could possibly be the first number. that probabilty is 1/7, so 7 options.
Now there are 4 slots left. and 10 numbers to choose from (including the number 0)
You could multiplty 4 times 4 10 times which equals 1048576.

As Wikipedia says, "In mathematics, an algebraic expression is an expression built up from integer constants, variables, and the algebraic operations (addition, subtraction, multiplication, division and exponentiation by an exponent that is a rational number). For example, 3x^2 − 2xy + c is an algebraic expression."
7 + x is the algebraic expression you'd want.

Answer:
It is C, x-axis
Step-by-step explanation: if the point is at 0 on the y-axis but on a number greater than or less than 0 on the x-axis then the point is on the x-axis line.
Answer:
Since the y-coordinate is zero, that means that our point lies on the x-axis because any point on the x-axis has a v-coordinate of 0. Therefore our best option would be option E (x-axis).

a triangle has two side lengths of 8.5 centimeters and 9.5 centimeters. What is a possible length for the third side? Explain why this is a possible length
Answers
Answer:
12.7 centimeters
Step-by-step explanation:
Using Pythagorean Theorem,
[tex]a^{2} +b^{2} =c^{2}[/tex]
8.5² + 9.5² = √162.5
√162.5 ≈ 12.7²
The possible side lengths for the third side of the given triangle is x ≤ 18.
What is Triangle?A triangle is a two dimensional figure which consist of three vertices, three edges and three angles.
Sum of the interior angles of a triangle is 180 degrees.
Given that,
a triangle has two side lengths of 8.5 centimeters and 9.5 centimeters.
We have to find the possible side lengths for the third side.
We know that,
"Triangle Inequality theorem" states that for a triangle, the sum of any two sides will be always greater than or equal to the third side.
Here, sum of first two sides ≥ length of third side
Let x be the third side.
8.5 + 9.5 ≥ x
18 ≥ x
Hence the possible side lengths are x ≤ 18.

The answer is 14,800 square yards.
Step-by-step explanation:
Square Area:bh: 145 x 80 = 11600
225-145=80/2= 40 (the base)
Triangle Area: 1/2 (b) (h): 1/2 (40) (80) = 1600
Since there are 2 riangles multiply 1600 by 2 = 3,200
Add 11600 + 3,200 = 14,800
