Answers
Answer:
The angle is 90, my friend gave the answer as 10, so he is incorrect
The complement of the angle is not 10 but 0
The measure of the supplement is 90 degrees
Step-by-step explanation:
The complement of an angle is simply the value of 90 minus the angle
The supplement of an angle is simply the value of 180 minus the angle
So let’s say the angle we are looking at is x
The complement of the angle will be 90 - x
The supplement of the angle will be 180-x
so from the question;
x = 90-x + 180-x
x = 270 - 2x
2x + x = 270
3x = 270
x = 270/3
x = 90
The measure of the angle is 90 degrees
the measure of the complement of this angle is 90-90 = 0 degrees
The measure of the complement is 180-90 = 90 degrees

It is given that there are about 30.2 million small businesses and about 30000 large businesses.
We have to find out what percent of all businesses in the U.S. are small businesses.
What do you mean by percentage ?
A percentage is a number or say ratio that can be expressed as a fraction of 100.
As per the question ;
The approximate number of small businesses is ;
= 30.2 million
= 30200000
The number of large businesses is ;
= 30000
Total number of businesses will be ;
= 30200000 + 30000
= 30230000

Question 2)
[tex]\text{ Part A) \cos(x)=\frac{12}{13}} \\ \text{ Part B) \sin(90-x)=\frac{12}{13} }[/tex][tex]\text{ Part A) }\\\cos(x)=\frac{12}{13}\\\\\text{ Part B)}\\\sin(90-x)=\frac{12}{13}[/tex]
Step-by-step explanation:
Question 1)
Please first reference below for the image.
Also recall the basic trigonometric functions with SohCahToa.
Part 1)
In order to find the distance, we will need to find the value of [tex]x[/tex]. However, to do so, we must find the value of [tex]c[/tex] first.
First, we will need to find BM. We can use the smaller triangle. BM is opposite of the smaller triangle, and we already know that the hypotenuse is 20 meters. So, we can use sine:
[tex]\sin(A)=\frac{\text{opp}}{\text{hyp}}[/tex]
Substitute 32° for A and 20 for the hypotenuse. Our BM is our opposite, so substitute BM for opposite. This yields:
[tex]\sin(32)=\frac{BM}{20}[/tex]
Solve for BM. Multiply both sides by 20:
[tex]BM=20\sin(32)[/tex]
Don't approximate just yet. In order to make our answer to most precise, we will approximate at the very end.
So, BM is 20sin(32) meters. BM of the smaller triangle is the same as BM of the larger triangle, so BM of the larger triangle is also 20sin(32). Now, we can find the value of [tex]c[/tex]. However, we will first need to find the value of [tex]\angle MBT[/tex]. To do so, notice that [tex]\angle ABM, \angle MBT, \text{ and } 40\textdegree[/tex] form a straight angle. Therefore:
[tex]\angle ABM+\angle MBT+40^\circ=180[/tex]
Simplify:
[tex]\angle ABM+\angle MBT=140[/tex]
So, we will need to find [tex]\angle ABM[/tex], which is [tex]\angle B[/tex] of the smaller triangle. So, we can use the trig functions again. Since we now know BM, we can use cosine. So:
[tex]\cos(B)=\frac{\text{adj}}{\text{opp}}[/tex]
Substitute 20sin(32) for the adjacent and 20 for the opposite. So:
[tex]\cos(B)=\frac{20\sin(32)}{20}[/tex]
To solve for B, take the inverse cosine of both sides. Evaluate:
[tex]B=\cos^{-1}(\frac{20\sin(32)}{20})=58^\circ[/tex]
Therefore, we can substitute 58 for [tex]\angle ABM[/tex] and solve. This yields:
[tex]58+\angle MBT=140\\\Rightarrow\angle MBT=82^\circ[/tex]
So, we can now find c. We know BM and that [tex]\angle B[/tex] (of the larger triangle) is 82°. To find c, then, we will use cosine. So:
[tex]\cos(B)=\frac{\text{adj}}{\text{hyp}}[/tex]
Substitute 82 for B, 20sin(32) for the adjacent BM, and c for the hypotenuse. So:
[tex]\cos(82)=\frac{20\sin(32)}{c}[/tex]
Solve for c by cross-multiplying:
[tex]c=\frac{20\sin(32)}{\cos(82)}[/tex]
Now, finally, we can solve for [tex]x[/tex]. We know [tex]c[/tex] (the hypotenuse) and we want to find [tex]x[/tex]. We also have an angle of 40°. So, we can use cosine:
[tex]\cos(40)=\frac{x}{c}[/tex]
Multiply both sides by [tex]c[/tex]:
[tex]x=c\cos(40)[/tex]
Substitute [tex]c[/tex]:
[tex]x=\frac{20\sin(32)\cos(40)}{\cos(82)}[/tex]
Approximate:
[tex]x\approx58.34\text{ meters}[/tex]
However, this is only [tex]x[/tex]. The distance from the house is [tex]x+20[/tex]. Therefore, the distance from the house is:
[tex]d\approx58.34+20\approx78.34\text{ meters}[/tex]
Part 2)
We want to find the height h. Since we already determined [tex]c[/tex], we can use it to find [tex]h[/tex]. We will use the sine function this time:
[tex]\sin(40)=\frac{h}{c}\\\Rightarrow h=c\sin(40)\\\Rightarrow h=\frac{20\sin(32)\sin(40)}{\cos(82)}\\\Rightarrow h\approx48.95[/tex]
However, we will still need to add the eye level of 182 centimeters or 1.82 meters. So:
[tex]h\approx48.95+1.82\approx50.77\text{ meters}[/tex]
The height of the house is approximately 50.77 meters.
Question 2)
We know that: [tex]\tan(x)=\frac{5}{12}[/tex]
Remember that tangent is the opposite side over the adjacent side. So, let's find the hypotenuse. We can us the Pythagorean Theorem:
[tex]a^2+b^2=c^2[/tex]
Substitute 5 for a and 12 for b. Solve for c:
[tex]c^2=(5)^2+(12)^2\\\Rightarrow c^2=25+144\\\Rightarrow c=\sqrt{169}=13[/tex]
So, our hypotenuse is 13, our adjacent is 12, and our opposite is 5. We can now solve for the others:
A)
[tex]\cos(x)=\frac{\text{adj}}{\text{hyp}}\\\Rightarrow\cos(x)=\frac{12}{13}[/tex]
B)
[tex]\sin(90-x)=\cos(x)\\\text{Note: This is a cofunction identity}\\\Rightarrow\sin(90-x)=\frac{12}{13}[/tex]
Note: The document I found said [tex]\sin^2(90-x)[/tex]. Anyways, it will just be: [tex]\sin^2(90-x)=\frac{144}{169}[/tex]

A piece of machinery depreciates $8000 the first year,
$7500 the second year, and $7000 the third year. If the
rate of depreciation is constant, what is the amount of
depreciation of the piece of machinery in the sixth year?
Answers
Answer:
6,500 = 4th year
6,000 = 5th year
5,500 = 6th year.
The amount of depreciation of the piece of machinery in the sixth year is $5000.
What is depreciation?A reduction in the value of an asset over time, due in particular to wear and tear.
Given that, a piece of machinery depreciates $8000 the first year, $7500 the second year, and $7000 the third year
The rate of depreciation is $500 per year
For 6 years the reduction is = 6*500 = $3000
Therefore, after 6 years = $8000 - $3000 = $5000
Hence, The amount of depreciation of the piece of machinery in the sixth year is $5000

Answers
Answer:
5.5 years
Step-by-step explanation:
24900 times 6.75% = 1,680.75
so this is how much it goes down per year, but we have to find it were the price reaches 15900. so 9000-1680.75=
7,319.25( one year)
7,319.25-1680.75 = 5,638.5 (second year)
5,638.5-1680.75= 3,957.75 (third year)
3,957.75-1680.75 = 2,277 (fourth year)
2,277-1680.75= 596.25 (fifth year)
