Answer: 17) 41.0° 18) 60.8° 19) 36.0° 20) 19.7°
Step-by-step explanation:
Law of Cosines: a² = b² + c² - 2bc · cos A
b² = a² + c² - 2ac · cos B
c² = a² + b² - 2ab · cos C
17) a = 29, b = 13, c = 21, C = ???
c² = a² + b² - 2ab · cos C
21² = 29² + 13² - 2(29)(13) · cos C
441 = 841 + 169 - 754 cos C
441 = 1010 - 754 cos C
-569 = -754 cos C
[tex]\dfrac{569}{754}=\cos C\\\\\cos^{-1}\bigg(\dfrac{569}{754}\bigg)=C[/tex]
41.0° = C
18) a = 29.3, b = 25.7, c = 16.8, B = ???
b² = a² + c² - 2ac · cos B
25.7² = 29.3² + 16.8² - 2(29.3)(16.8) · cos B
660.49 = 858.49 + 282.24 - 984.48 cos B
660.49 = 1140.73 - 984.48 cos B
-480.24 = -984.48 cos B
[tex]\dfrac{480.24}{984.48}=\cos B\\\\\cos^{-1}\bigg(\dfrac{480.24}{984.48}\bigg)=B[/tex]
60.8° = B
19) a = 12, b = 19, c = 11, A = ???
a² = b² + c² - 2bc · cos A
12² = 19² + 11² - 2(19)(11) · cos A
144 = 361 + 121 - 418 cos A
144 = 482 - 418 cos A
-338 = -418 cos A
[tex]\dfrac{338}{418}=\cos A\\\\\cos^{-1}\bigg(\dfrac{338}{418}\bigg)=A[/tex]
36.0° = A
20) a = 10, b = 9, c = 18, A = ???
a² = b² + c² - 2bc · cos A
100² = 9² + 18² - 2(9)(18) · cos A
100 = 81 + 324 - 324 cos A
100 = 405 - 324 cos A
-305 = -324 cos A
[tex]\dfrac{305}{324}=\cos A\\\\\cos^{-1}\bigg(\dfrac{305}{324}\bigg)=A[/tex]
19.7° = A
Answer:
7) 41.0° 18) 60.8° 19) 36.0° 20) 19.7°

Calculate the a50 term of the geometric sequence with a28 = 3 and r = -1
Answer:
3
Step-by-step explanation:
multiplying by -1 only changes the number if you're multiplying an odd amount of times, but this time you're going from 28 to 50, so it's even, so the number stays the same.
By substituting in the values of the variables, complete the addition number sentence that corresponds to the diagram below,
Answer:
[tex] a + b + c = 5 + 6 + 11 = 22 [/tex]
Step-by-step explanation:
Variable "a" and "b" represents distances on the numberline.
Variable "c" is the combined distance of the values of variable "a" and variable "b" on the numberline.
a = length of red line = |5 - 0| = |5| = 5
b = length of blue line = |11 - 5| = |6| = 6
c = length of black line (red+blue) = |11 - 0| = |11| = 11
Therefore:
[tex] a + b + c = 5 + 6 + 11 = 22 [/tex]
3w – 15
Factoring out the GCF
The factored form of 3w - 15, after factoring out the Greatest Common Factor, is 3(w - 5).
To factor out the greatest common factor (GCF) from the expression 3w - 15, we first need to determine the GCF of the two terms.
In this case, the GCF of 3w and 15 is 3. Both terms are divisible by 3.
To factor out the GCF, we divide each term by the GCF:
3w/3 - 15/3
Simplifying further, we have:
w - 5
Therefore, the factored form of 3w - 15, after factoring out the GCF, is 3(w - 5).
Factoring out the GCF is a process that involves identifying the highest common factor of all the terms in an expression and dividing each term by that factor. This helps simplify the expression and can make it easier to work with or further factorize if needed.
In this case, the GCF was 3, so we divided both terms by 3 to factor it out, resulting in the simplified expression w - 5.

Step-by-step explanation:
Soccer ball specifications require a diameter of 8.65 inches with an allowable margin of error of 0.05 inch.
Use this information to complete these statements.
The equation that can be used to find d, the diameter of a new soccer ball, is
| ____ | = ____
The minimum possible diameter of a soccer ball is ____,
and the maximum possible diameter is ____
Answer:
Equation for new diameter: |d' - 8.65| ≤ 0.05
Minimum possible diameter = 8.60 inches
Maximum possible diameter = 8.70 inches
Step-by-step explanation:
We are told that:
Ball specifications require a diameter (d) = 8.65 inches.
Allowable margin of error = 0.05 inch
Now, since we have a value for the allowable margin of error, it means that the absolute value equation to determine the possible value or the new diameter (d') would be;
|d' - 8.65| ≤ 0.05
Minimum possible diameter = 8.65 - 0.05 = 8.60 inches
Maximum possible diameter = 8.65 + 0.05 = 8.70 inches

Customers at a certain pharmacy spend an average of $54.40, with a standard deviation of $13.50.What are the largest and smallest amounts spent by the middle 50% of these customers?
Answer:
Largest is [tex]x_2 = \$ 63.506[/tex]
Smallest is [tex]x_1 = \$ 45.29[/tex]
Step-by-step explanation:
From the question we are told that
The mean is [tex]\mu = \$ 54.40[/tex]
The standard deviation is [tex]\sigma = \$ 13.50[/tex]
The largest and the smallest amount spent by 50% of the costumer is mathematically represented as
[tex]P(x_1 < X < x_2) = P(\frac{ x_1 -\mu}{\sigma } < \frac{X - \mu }{ \sigma } < \frac{ x_2 -\mu}{\sigma } ) = 0.50[/tex]
=> [tex]P(x_1 < X < x_2 ) = P(\frac{x_1 - 54.40}{ 13.50} < X < \frac{x_2 - 54.40}{ 13.50} ) = 0.50[/tex]
Given that this is normally distributed we have that
[tex]P(X <- \frac{x_1 - 54.40}{ 13.50} ) = 0.25[/tex]
and
[tex]P(X < \frac{x_2 - 54.40}{ 13.50} ) = 0.25[/tex]
From the normal distribution curve that z-score having a probability of 0.25 is
0.6745
So
[tex]\frac{x_1 - 54.40}{ 13.50} = -0.6745[/tex]
=> [tex]x_1 = \$ 45.29[/tex]
and
[tex]\frac{x_2 - 54.40}{ 13.50} = 0.6745[/tex]
=> [tex]x_2 = \$ 63.506[/tex]
When writing a repeating decimal as a fraction, does the number of repeating decimal digits you use matter? Explain.
Answer:
No
Step-by-step explanation:
If you have a repeating decimal it doesn't matter who many decimal digits there are. Most repeating decimals I have encountered end up converting into a fraction that has a denominator of 9.
Hope This Helps :)
Answer:
It depends
Step-by-step explanation:
It depends on what the repeating decimal is. For instance if the decimal is a repeating 8 then you only have to use one digit. If, however, it is something like .673673673 going on forever you just need however many until it loops again. In this case you would need three, because that is how long the loop is.

If 50 percent of the families in a certain city subscribe to the morning newspaper, 65 percent of the families subscribe to the afternoon newspaper, and 85 percent of the families subscribe to at least one of the two newspapers. What percentage of the families subscribe to both newspapers?
Answer: 30%
Step-by-step explanation:
Given, Percent of families subscribe to the morning newspaper = 50%
Percent of families subscribe to the afternoon newspaper = 65%
Percent of families subscribe to at least one of the two newspapers. = 85%
Now, percentage of the families subscribe to both newspapers = % for morning newspaper + % for afternoon newspaper - % for at least one of the two newspapers
= (50+65 - 85) %
= 30 %
Hence, the percentage of the families subscribe to both newspapers = 30%

Jade receives total employment benefits that are 17.5% of her gross annual pay. If Mary has a gross annual pay of $60,500, how much in total job benefits does she receive?
A. $71,087
B. $81,087
C. $61,087
D. $51,087
Answer:
A. $71,087
Step-by-step explanation:
The name jade and Mary contradict each other, let's assume both jade and Mary refers to the same person
Jade receives job benefits of 17.5% of her annual gross pay
Jade has an annual gross pay of $60,500
how much in total job benefits does she receive?
Total job benefits received = 17.5% of $60,500 + $60,500
= (17.5 / 100 * 60,500) + 60,500
= (0.175 * 60,500) + 60,500
= 10,587.5 + 60,500
= $71,087.5
The rounded value closest to the answer in the option is $71,087

At the store, Jason find the volume of a soda pack is 423.9 in.³. If each cylinder shaped can has a height of 6 inches and a diameter of 3 inches, how many soda cans are in a pack? (Use 3.14 for pi)
Answer : The correct option is, (A) 10
Step-by-step explanation :
First we have to calculate the volume of cylinder shaped can.
Formula used:
Volume of cylinder = π r² h
where,
r = radius of cylinder
h = height of cylinder
Given:
Diameter of cylinder = 3 in
Height of cylinder = 6 in
Radius of cylinder = [tex]\frac{Diameter}{2}=\frac{3in}{2}=1.5in[/tex]
Now putting all the given values in the above formula.
Volume of cylinder = π r² h
Volume of cylinder = 3.14 × (1.5 in)² × 6 in
Volume of cylinder = 42.39 in³
Now we have to determine the number of soda cans are in a pack.
Number of soda cans are in a pack = [tex]\frac{\text{Volume of soda pack}}{\text{Volume of cylinder shaped can}}[/tex]
Number of soda cans are in a pack = [tex]\frac{423.9in^3}{42.39in^3}[/tex]
Number of soda cans are in a pack = 10
Therefore, the number of soda cans in a pack are 10.
