A triangle has a total of 180 degrees in it , however we already know one side is 45, so we can add that to the solution, we also know that 2 sides are the exact same, so therefore, we will be multiplying our unknown value ( x = 67.5 btw, not so unknown) by 2, and you will always get 180 degrees, thats how you check your answer, also if you sbutract 45 from 180 and divide the product by 2 you will get the value of x ( which is 67.5).
Thats It Helps It Helps!
A regular pentagon has an area of 124.25 square meters, and each side of the pentagon measures 7.1 meters.
What is the length of an apothem of the pentagon?
Enter your answer in the box.
Answer:
7 m
Step-by-step explanation:
To find the length of the apothem of a regular pentagon, we can use the formula:
apothem = (side length) / (2 * tan(180/n))
where n is the number of sides of the regular polygon.
In this case, the side length of the pentagon is 7.1 meters and n is 5. Plugging in these values, we get:
apothem = (7.1) / (2 * tan(180/5))
apothem = 7 meters (rounded to the nearest meter)
Therefore, the length of the apothem of the pentagon is 7 meters.

In a study of 479,908 cell phone users, it was found that 213 developed cancer of the brain or nervous system. Assuming that cell phones have no effect, there is a 0.000462 probability of a person developing cancer of the brain or nervous system. We therefore expect about 222 cases of such cancer in a group of 479,908 people. Estimate the probability of 213 or fewer cases of such cancer in a group of 479,908 people. What do these results suggest about media reports that cell phones cause cancer of the brain or nervous system?
Answer:
The probability of 213 or fewer cases of such cancer in a group of 479,908 people is 0.2776.
Step-by-step explanation:
We are given that assuming that cell phones have no effect, there is a 0.000462 probability of a person developing cancer of the brain or nervous system. We, therefore, expect about 222 cases of such cancer in a group of 479,908 people.
Let \(\hat p\) = sample probability of a person developing cancer of the brain or nervous system.
The z-score probability distribution for the sample proportion is given by;
Z = \(\frac{\hat p-p}{\sqrt{\frac{\hat p(1-\hat p)}{n} } }\) ~ N(0,1)
where, p = population probability of a person developing cancer of the brain or nervous system = 0.000462
n = sample of cell phone users = 479,908
Now, the probability of 213 or fewer cases of such cancer in a group of 479,908 people is given by = P(\(\hat p\) \(\leq\) \(\frac{213}{479,908}\) )
P(\(\hat p\) \(\leq\) 0.000444) = P(\(\frac{\hat p-p}{\sqrt{\frac{\hat p(1-\hat p)}{n} } }\) \(\leq\) \(\frac{0.000444-0.000462}{\sqrt{\frac{0.000444(1-0.000444)}{479,908} } }\) ) = P(Z \(\leq\) -0.59)
= 1 - P(Z < 0.59) = 1 - 0.7224 = 0.2776
The above probability is calculated by looking at the value of x = 0.59 in the z table which has an area of 0.7224.
These results suggest about media reports that cell phones cause cancer of the brain or nervous system that there is around 28% chance that 213 or fewer cases of such cancer in a group of 479,908 people can take place.

dentify the type of transformation in the following graphic and describe the change.
Answer:
Translation, five units to the left
Step-by-step explanation:
Point A is moved to the left to become A'.
Similarly, Points M, H, and T have moved to the left to become M', H', and T', respectively.
This type of transformation, in which all the points in a figure move in the same direction and by the same amount, is called a translation (moving sideways).
Each point has moved five units to the left.

The Silver Spur is a popular local hiking trail. The start of the trail is 179ft above sea level. The table shows the amount of elevation gain between the previous point of interest on the trail and the current one. (The elevation gain shown for the Old Cabin is the elevation gained between the start of the trail and the Old Cabin.) Point of Interest Elevation gain (in ft) Old Cabin −32.78 Ruby Falls 8634 Thunder Gorge −14725 High Point Vista 346.47 What is a hiker’s elevation above sea level (in feet) upon reaching High Point Vista?
Answer:
Step-by-step explanation:
To find the hiker's elevation above sea level upon reaching High Point Vista, we need to add up the elevation gain from the start of the trail to High Point Vista. We can use the table to do this:
Elevation gain from start to Old Cabin: -32.78 ft (negative because the hiker loses elevation)
Elevation gain from Old Cabin to Ruby Falls: 8634 ft
Elevation gain from Ruby Falls to Thunder Gorge: -14725 ft (negative because the hiker loses elevation)
Elevation gain from Thunder Gorge to High Point Vista: 346.47 ft
To find the hiker's elevation above sea level at High Point Vista, we add up these elevation gains:
179 ft (start) - 32.78 ft + 8634 ft - 14725 ft + 346.47 ft = -5668.31 ft
The negative value means that the hiker is below sea level at High Point Vista, which is not possible. Therefore, there must be an error in the elevation gain listed for one of the points of interest. It's possible that the elevation gain for Ruby Falls is incorrect, as it seems unlikely that the hiker would gain more than 8000 ft in elevation between Old Cabin and Ruby Falls. Without more information, it's difficult to say for sure where the error lies.

Help please!! I will mark brainilist and give a lot of points.
This is Pythagorean theorem.
Formula: a^2+b^2=c^2
When I say ^2 I mean to the power of 2.
The question is asking me to solve for a.
Then give me b and c which is b = 17 1/3 and c = 16.
How do I solve for a when b is greater than c? Won’t that give me a negative a? You can’t have a negative a right?
Unless I’m wrong.
Please help my solve this!!!!! :D

a = 23.588
Step-by-step explanation:
a^2 = 17 1/3^2 + 16^2
a^2 = 300.4 + 256
a^2 = 556.4
a = 23.588 (I rounded to thousandths but you can round to whatever)
Hello there,
I just looked into the question and you are absolutely right whatever you inferred.I think the question might be wrong.The value of c should be greater than b.I guess it will like this:\(b = 16 \: \: \: c = 17 \frac{1}{3} \)The values should be like this.I am solving the equation by this:\( {a}^{2} = {c}^{2} - {b}^{2} \\ = > {a}^{2} = {(17 \frac{1}{3}) }^{2} - {(16)}^{2} \\ = > {a}^{2} = {( \frac{52}{3} )}^{2} - {(16)}^{2} \\ = > {a}^{2} = ( \frac{52}{3} - 16)( \frac{52}{3} + 16) \\ = > {a}^{2} = ( \frac{52 - 48}{3} )( \frac{52 + 48}{3} ) \\ = > {a}^{2} = \frac{4}{3} \times \frac{100}{3} \\ = > {a}^{2} = \frac{400}{9} \\ = > a = \sqrt{ \frac{400}{9} } \\ = > a = \frac{20}{3} \\ = > a = 6 \frac{2}{3} \)So, the value of a is \(a = 6 \frac{2}{3} \)Hope you could get an idea from it.

Solve for x:
2x + 3 = 7
Answer:
x = 2
Step-by-step explanation:
First, subtract 3 from both sides.
2x + 3 = 7
- 3 -3
2x = 4
Then, divide both sides by 2.
2x / 2 = 4 / 2
x = 2
Answer:
the solution for x is x = 2
Step-by-step explanation:
To solve for x, we need to get x by itself on one side of the equation. First, we can subtract 3 from both sides to get:
2x + 3 - 3 = 7 - 3
Simplifying the left side gives us:
2x = 4
Then, we can divide both sides by 2 to get:
2x / 2 = 4 / 2
Simplifying the left side gives us:
x = 2
A square piece of paper has an area of x2 square units. A
rectangular strip with a width of 2 units and a length of x
units is cut off of the square piece of paper. The remaining
piece of paper has an area of 120 square units.
Answer:
Length of rectangular strip = 12
area of rectangular strip = 2*12 = 24
Area of square = x^2 = 12^2 = 144
Step-by-step explanation:
Area of square x^2
area of rectangle is given by length * width
Length of rectangular strip = x
width of rectangular strip = 2
area of rectangular strip = length * width = 2*x = 2x
Area of square piece of paper when rectangular strip is taken away from it
= Area of square - area of rectangular strip
= \(x^2 -2x\)
It is given that Area of square piece of paper when rectangular strip is taken away from it is 120 square units.
Thus,
\(x^2 -2x = 120\\=> x^2 -2x -120 = 0\\=> x^2 -12x +10x-120\\=> x(x-12) +10(x-12)\\=> (x+10)(x-12) = 0\\\\\)
Thus,
either x+10 = 0 or x -12= 0
x = -10 or x = 12
but length cannot be negative hence neglecting x = -10
hence value of x is 12.
Hence,
Length of rectangular strip = 12
area of rectangular strip = 2*12 = 24
Area of square = x^2 = 12^2 = 144
A company sells product for $69 each. The variable costs are $9 per unit and fixed costs are $45,000 per month.
SOLUTION
Given the question in the image, the following are the solution steps to answer the question.
STEP 1: Define the revenue function TR
Total revenue is given as:
\(Number\text{ of units sold }\cdot Cost\text{ per unit}\)By calculation,
Let n represents the number of items sold
\(\begin{gathered} By\text{ substitution,} \\ one\text{ item = \$69} \\ TR=69n \end{gathered}\)Total revenue cost is given as 69n
STEP 2: Define the Total cost function
The formula for total cost is given as:
\(\begin{gathered} TC=an+b \\ where\text{ a is the unit cost} \\ n\text{ is the number of items } \\ b\text{ is the fixed cost} \end{gathered}\)The known details from the given question are:
\(\begin{gathered} a=\text{ \$}9 \\ n=n \\ b=\text{ \$}45000 \\ \\ TC=9n+45000 \end{gathered}\)Total cost is given as 9n+45000
STEP 3: Calculate the number of units needed to be sold to break even
Here, we equate TC to TR and this is given as:
\(\begin{gathered} TR=TC \\ 69n=9n+45000 \\ 69n-9n=45000 \\ 60n=45000 \\ n=\frac{45000}{60}=750 \end{gathered}\)Hence, 750 units are needed to be sold
STEP 4: Calculate the revenue at the break-even
We get this by substituting 750 for n in the Revenue function
\(\begin{gathered} TR=69n \\ n=750 \\ TR=69(750)=\text{ \$}51750 \end{gathered}\)Hence, the TR at the breakeven is $51750
231 - 7a = 98
How to solve this
Answer:
19
Step-by-step explanation:
231 - 7a = 98 = -7a + 231 = 98
Subtract 231 from both sides to get -7a = -133
Divide by -7 on both sides to get a = 19
Answer:
a = 19 is the correct solution.
Step-by-step explanation:
Step 1 : Start by simplifying both sides of the problem.
231 − 7a = 98
231 + − 7a = 98
−7a + 231 = 98
Step 2 : Next step is to subtract 231 from both sides
−7a + 231 − 231 = 98 − 231
−7a = −133
Step 3: Finally, divide both sides by -7.
( When I use the symbol /, it signifies I'm dividing.)
-7a/-7 = -133/-7
-133 divided by -7 equals 19
This shows that a = 19. I hope this helps! :D

Answer:
Step-by-step explanation:
The slope of the graph of y = -3x is -3. The slope of a line is the amount that the line rises or falls for every unit it moves horizontally. In this case, the line rises by -3 units for every 1 unit it moves horizontally. This means that the slope of the line is -3.
