Answer:
20
Step-by-step explanation:
the number line is patterned in twos, so the dot will be at 20, since its 4 spaces away from 12
Answer:
20
Step-by-step explanation:
If you look between the 8 and the twelve you see they went up by 4. Then you see they go up 2 each line. 8, 10, 12,14,16,18, therefore having the answer being 20.

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.)
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.
now you multiply that by 7. 1048576 times 7 equals
There are 7340032 zipcodes that are possible.

Represent the following sentence as an algebraic expression, where "a number" is the letter x.
7 plus a number.
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.
Let a, b, c be the three rational numbers where a = 2 3 , b = 4 5 and c = − 5 6 Verify: Associative property of addition

1. The prism-shaped roof has equilateral triangular bases. Create an equation that models the height of one of the roof's triangular bases in terms of its sides. In your final answer, include all necessary calculations.
2. The prism-shaped roof has equilateral triangular bases. Use the model you created in question #1 to calculate the height of the roof, to the nearest tenth of a foot, if the side lengths each measure 25 feet. In your final answer, include all necessary calculations.
3. To determine the amount of roofing materials needed, the area of the roof's entire surface is calculated, including the ceiling of the garage. Considering the sketch of the roofing design, create a formula to model the area of the roof's entire surface. In your final answer, include all of your calculations.
4. The contractor in charge of the roofing project is trying to make the job the most cost effective for the homeowners. In order to cut back on the cost of supplies, he decides that a ceiling in the garage is not necessary. In other words, there will not be a barrier built between the garage and the roof. In two or more complete sentences, explain how these changes affect the model for the area of the roof's entire surface.

Create a formula modeling the area of the roof’s surfaces that the contractor will be purchasing supplies for.
6. Use the formula you created in the previous question to calculate the area of the roof that the contractor will be purchasing supplies for, assuming that the side length of the triangular bases is 25 feet and the length of each rectangular face is twice its width.
Answer:The answer is given below.
Step-by-step explanation:
As shown in the attached figure, the prism-shaped roof has equilateral triangular bases, one of which is ΔABC. We need to create an equation that models the height of one of the roof's triangular bases in terms of its sides. Let ii be AD.SEe the figure attached herewith, ΔABC forms an equilateral triangle, in which AD is the height. So, D will be the mid-point of BC and ∠ADB = ∠ADC = 90°.Now, in ΔADB, we haveThus, with the help of this model, we can find the height of any one of the roof's triangular bases..
