On A Map, The North Carolina Cities Of Raleigh, Durham, And Chapel Hill Form A Triangle, As Shown Below.

Answers

Answer 1
Answer

The approximate values are:

c = 55.2°

r = 22.8°

x = 9.9 miles

Explanation

- To find angle [tex]c[/tex], we are using the rule of sines: [tex]\frac{a}{sin(A)} =\frac{b}{sin(B)} =\frac{c}{sin(C)}[/tex]

For our triangle [tex]a=21,A=c,b=x,B=r,c=25[/tex] and [tex]C=102[/tex]

Replacing the values we get: [tex]\frac{21}{sin(c)} =\frac{x}{sin(r)} =\frac{25}{sin(102)}[/tex]

We can pick up two suited values to find [tex]c[/tex]:

[tex]\frac{21}{sin(c)} =\frac{25}{sin(102)}[/tex]

[tex]21=\frac{25sin(c)}{sin(102)}[/tex]

[tex]21sin(102)=25sin(c)[/tex]

[tex]sin(c)=\frac{21sin(102)}{25}[/tex]

[tex]c=sin^{-1}(\frac{21sin(102)}{25})[/tex]

[tex]c=55.2[/tex]

- Now that we have angle [tex]c[/tex], we can use the angle sum theorem to find angle [tex]r[/tex].

The angle sum theorem states the the interior angles of a triangle add up to 180°, so:

[tex]r+c+102=180[/tex]

[tex]r+55.2+102=180[/tex]

[tex]r+157.2=180[/tex]

[tex]r=22.8[/tex]

- Now that we have angle [tex]r[/tex], we can use the rule of sines, one more time, to find side [tex]x[/tex]

[tex]\frac{21}{sin(c)} =\frac{x}{sin(r)} =\frac{25}{sin(102)}[/tex]

[tex]\frac{x}{sin(r)} =\frac{25}{sin(102)}[/tex]

[tex]\frac{x}{sin(22.8)} =\frac{25}{sin(102)}[/tex]

[tex]x=\frac{25sin(22.8)}{sin(102)}[/tex]

[tex]x=9.9[/tex]

Which expression is equivalent to 30m2+12m+18?? Please help ASAP !

Answers

Answer:

c) 6(5m2+2m+3)

Step-by-step explanation:

Given expression = 30m2 + 12m + 18

The simplified form can be calculated by taking GCF

The GCF of 30m2, 12m and 18 is = 6

Therefore, the expression becomes

(6*5m2 + 6*2m + 6*3)

Your science teacher recently gave a quiz to 28 students present in class. The class average was an 82.5. Five students that were absent made up the quiz after schoolamd their scores were a 78, 89,92,,99, & 63. Find the new class average with the newscores

Answers

Total students in the class who got the quiz = 28

The average of the class average was = 82.5

Five students that were absent made up the quiz after school and their scores were a 78, 89,92,99, & 63.

The formula for an average= (sum of values) / (count of values)

As the average is given as 82.5 and there were 28 students, so sum of the 28 values will be = [tex]28\times82.5=2310[/tex]

Total students of the class = 28+5(absent) = 33

For 33 students the total score was = 2310 +(78+89+92+99+63)

= 2731

So, average for 33 students will be = [tex]\frac{2731}{33} =82.757[/tex] or 82.76

So, the new class average is 82.76

Answers

I think it's c. No solution

Final answer:

The solution for the given system of linear equations is (1, -2), which is not provided in the options given. A possible typo may exist in the options.

Explanation:

This question is asking for the solution to a system of linear equations. The equations were given as 4y − 36 = −12x and 3x + y = −9. To solve this system, we can use the method of substitution or elimination. First, let's rewrite the first equation in terms of x. Dividing each side of 4y - 36 = -12x by -12, we get x = -y/3 + 3. We can then substitute (-y/3 + 3) for x into the second equation, yielding 3(-y/3 + 3) + y = -9. Solving Yields y = -2 and substituting y = -2 into x = -y/3 + 3 gives x = 1. So, the solution to this system is x = 1, y = -2. So the correct answer is (1, -2), which was not provided in the options. It seems there might be a typo in the options provided.

Albert buys a car for $12,000. The value of the car depreciates about 9% per year. After about how many years will the car be worth $7500?

Answers

Answer:

[tex]5\ years[/tex]  

Step-by-step explanation:

we know that

The  formula to calculate the depreciated value  is equal to  

[tex]D=P(1-r)^{t}[/tex]  

where  

D is the depreciated value  

P is the original value  

r is the rate of depreciation  in decimal  

t  is Number of Time Periods  

in this problem we have  

[tex]P=\$12,000\\r=9\%=0.09\\D=\$7,500[/tex]

substitute in the formula above and solve for t

[tex]\$7,500=\$12,000(1-0.09)^{t}[/tex]  

[tex](7,500/12,000)=(0.91)^{t}[/tex]  

Apply log both sides

[tex]log(7,500/12,000)=t*log(0.91)[/tex]  

[tex]t=log(7,500/12,000)/log(0.91)=5\ years[/tex]

B.
For every woman who likes running, 7 women like playing golf.
C.

Answers

Final answer:

Among the given options, statement D, which says 'For every man who likes running, 7 men like playing golf,' is the correct statement based on the numbers provided.

Explanation:

In order to determine which statement is correct, we would need to relate the numbers given in the question. So let's take a look.

We have 14 men who like playing golf and 2 men who like running. So for each man that likes running, there are 14/2 = 7 men who like playing golf.We have 6 women who like playing golf and 18 women who like running. So for each woman that likes running, there are 6/18 = 1/3 women who like playing golf. This does not match either statement A or B. So we can rule them out.

With this comparison, we can conclude that the correct statement is D. For every man who likes running, 7 men like playing golf.
