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.

Answers
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..

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.

Sandi bought a sandwich and a milkshake. She spent $12 in all. The equation s + 4.25 = 12 can be used to determine the cost of each sandwich. Which of the following os the solution to the equation?
A. $7.75. C. $16
B. $8.75. D. $16.25
Answers
A) $7.75
explanation:
To find s, we need to isolate the variable. Use the inverse property of addition to subtract 4.25 from both sides. s + 4.25 - 4.25 = s. 12 - 4.25 = 7.75. Now we're left with s = 7.75.

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.
now you multiply that by 7. 1048576 times 7 equals
