Suppose a = 5 and A = 75 degrees.
Find:
The side lengths of given triangle is;
a=5 units
b=18.72 units
c=18.99 units
What is triangle?A triangle is a closed, two-dimensional figure with three straight sides and three angles. It is one of the basic shapes in geometry and is formed when three non-collinear points are connected by straight lines. The sum of the interior angles of a triangle is always 180 degrees, and there are various types of triangles, including equilateral triangles (where all three sides are of equal length and all three angles are 60 degrees), isosceles triangles (where two sides are of equal length), and scalene triangles (where all three sides and angles are different). Triangles are used in many different areas of mathematics and science, including trigonometry, geometry, and physics.
Here,
We can use the trigonometric ratios of sine, cosine, and tangent to find the values of b and c. First, we can use the fact that the sum of the angles in a triangle is 180 degrees to find angle C:
C = 180 - A - B = 180 - 75 - 90 = 15 degrees
Next, we can use the definition of the sine ratio:
sin(A) = opposite/hypotenuse
to find c:
sin(75) = 5/c
c = 5/sin(75) ≈ 18.99
Finally, we can use the Pythagorean theorem:
a² + b² = c²
to find b:
b² = c² - a²
= (18.99)² - 5²
≈ 350.66
b ≈ √350.66 ≈ 18.72
Therefore, a ≈ 5, b ≈ 18.72, and c ≈ 18.99.

Jorge Holland is having a new furnace installed. The furnace costs $3,500.00. The bank requires a down payment of 20 percent and 36 monthly payments of $85.18 each. What is the APR on his loan?
Answer:
Down payment = $3,500 x 0.20 = $700.00So the amount of the loan is:Loan amount = $3,500.00 - $700.00 = $2,800.00Now we can use the formula for the present value of an annuity to find the APR:PV = PMT x [(1 - (1 + r)^-n) / r]where PV is the present value (in this case, $2,800.00), PMT is the monthly payment ($85.18), r is the monthly interest rate, and n is the number of months (36).Solving for r, we get:r = 0.01301 or 1.301%Since the monthly interest rate is 1.301%, the APR is:APR = 12 x 1.301% = 15.61%Therefore, the APR on Jorge Holland's loan is 15.61%.

D It is much bigger.
The difference between the Statue of Liberty compared to other outdoor statues is that it is made of copper which is option C.
Statue of liberty explained.
The Statue of Liberty is a colossal neoclassical sculpture located on Liberty Island in New York Harbor in the United States. It was a gift from the people of France to the people of the United States, dedicated on October 28, 1886, and has since become one of the most recognizable symbols of the United States and its ideals of freedom and democracy.
The statue was designed by French sculptor Frédéric-Auguste Bartholdi, with the help of engineer Gustave Eiffel. The statue depicts a female figure dressed in a flowing robe and holding a torch in one hand and a tablet in the other, upon which is inscribed the date of the American Declaration of Independence (July 4, 1776).
The Statue of Liberty is unique among outdoor statues in that it is made of copper sheets that have oxidized over time to form a green patina. This patina has become an iconic symbol of the statue and is a result of the natural process of copper corrosion. The statue was originally a shiny brown color, but the oxidation of the copper has gradually changed its appearance over time.
Therefore, while the Statue of Liberty is also located in a park and on a pedestal, and it is larger than many outdoor statues, these characteristics are not unique to the statue and can be found in other outdoor statues as well.

You give your home health patient an unopened 500mL bottle of Mucinex and tell them to take 2 teaspoons 4 times a day as ordered. Your patient then ask you, "How long will this bottle last?" What will you tell your patient? (Respond to both questions.)
Answer:
the bottle will last approximately 12.5 days if the patient takes 2 teaspoons (10 mL) of Mucinex 4 times a day as ordered.
Step-by-step explanation:
Assuming that one teaspoon is equivalent to 5 milliliters (mL), then 2 teaspoons would be 10 mL. Therefore, the patient will be taking a total of 10 mL four times a day, which is 40 mL per day.
Since the bottle contains 500 mL, we can calculate how long the bottle will last by dividing the total volume of the bottle by the daily dose:
Number of days = Total volume of bottle / Daily dose
Number of days = 500 mL / 40 mL per day
Number of days = 12.5 days
Therefore, the bottle will last approximately 12.5 days if the patient takes 2 teaspoons (10 mL) of Mucinex 4 times a day as ordered.
3.1. 1 Three friends Anna, Manna and Hanna are doing the decorations for matric farewell dance. Anna put up two - fifth of the decoration, Manna put up one-fourth and Hanna put up three-tenth of the decoration. Is this job complete at this stage? If not, what fractional amount of job is still left to do? Show all necessary calculations to prove your answer. [13]
Answer:
Step-by-step explanation:
To determine if the job is complete, we need to add up the fractions of the decoration that each person put up:
Anna: 2/5
Manna: 1/4
Hanna: 3/10
Now we can find the total fraction of the decoration that they put up by adding these fractions:
2/5 + 1/4 + 3/10 = 16/40 + 10/40 + 12/40 = 38/40
So they have completed 38/40 of the decoration. To find the fraction of the job that is still left to do, we can subtract this from 1:
1 - 38/40 = 2/40
Therefore, there is still 2/40 of the decoration left to do, or 1/20 of the total job.

PWSB has a deal where they give you $100.00 to start a savings account. In addition, you decide toput money in the bank for 5 weeks and finish with $50.00.
a. Assuming you save the same amount every week, write an equation where y is the total
money in the savings account and x represents the number of weeksyou saved money.
b. What do the slope and y-intercept represent in the context of the problem?
Someone please help me with this it is a linear equation I think and the formula is y=Mx+b
y = $100.00 - $10.00x is the equation for the total amount of money in the savings account after x weeks.
The y-intercept represents the initial deposit of $100.00 and the slope is -10
How to find the expressiona. Let's call the amount of money saved each week "s" and
let's call the total amount of money in the savings account after "x" weeks "y".
Since the amount saved each week is the same, we can express the total amount of money in the savings account as:
y = $100.00 + sx
We know that at the end of the 5th week, the total amount in the savings account is $50.00. So we can set up the following equation:
$50.00 = $100.00 + 5s
solving for s:
$50.00 - $100.00 = 5s
-$50.00 = 5s
-10 = s
So the equation for the total amount of money in the savings account after x weeks is:
y = $100.00 - $10.00x
b. In the context of this problem, the slope represents the amount of money that is saved each week.
In this case, the slope is -10, meaning that $10.00 is saved each week. The y-intercept represents the initial deposit of $100.00.

There would be $2203.50 in Stony's account by September 2020 using simple interest formula.
As the bank charges an annual 8% simple interest, we may apply the following formula:
Simple interest is calculated as follows: Principle is the initial investment, Rate is the annual interest rate, and Time is the duration in years.
Here, the principal (P) is $1575, the interest rate (r) is 8%, and the time (t) is 5 since we need to know how much money Stony will have in his account by September 2020, which is five years from now.
We may calculate Stony's interest earnings over a five-year period using the simple interest formula:
Interest is calculated as follows: $1575 x 0.08 x 5 = $628.50
Stony's account will therefore have the following balance by September 2020: Total Amount = Principal + Interest = $1575 + $628.50 = $2203.50
Therefore by September 2020, Stony would have $2203.50 in his account.

Step 1: To convert 1.33 repeating into a fraction, begin writing this simple equation:
n = 1.33 (equation 1)
Step 2: Notice that there are 2 digitss in the repeating block (33), so multiply both sides by 1 followed by 2 zeros, i.e., by 100.
100 × n = 133.333 (equation 2)
Step 3: Now subtract equation 1 from equation 2 to cancel the repeating block (or repetend) out.
100 × n = 133.333
1 × n = 1.33
99 × n = 132
132
99
could be the answer, but it still can be put in the simplest form, i.e., reduced.
To simplify this fraction, divide the numerator and denominator by 33 (the GCF - greatest common factor).

Step-by-step explanation: The band expects to put 12 songs on their next CD. They write and record 25% more songs than they expect, which means they wrote and recorded 12 + (0.25 x 12) = 15 songs. During the editing process, 80% of the songs are removed. 80% of 15 is (0.80 x 15) = 12 songs. Subtracting the removed songs from the recorded songs, we get 15 - 12 = 3 songs that will be on the final CD. Therefore, there will be 3 songs on the final CD.

Part ll: what equation can Miguel set up to solve for the annual interest rate he needs to double his money by the time he retires?
Part lll: What annual interest rate does Miguel need to double his money by the time he retires?
Miguel has to put up the equation r = 72/16.
4.5% is the interest rate.
What is the 72-hour rule?For calculating how long it would take for an investment to double in value, the rule of 72 is utilised. To get the doubling time, divide 72 by the interest rate.
To use the rule of 72, you simply divide the number 72 by the annual interest rate. For example, if the interest rate is 6%, the rule of 72 predicts that it will take approximately 12 years (72 ÷ 6 = 12) for the investment to double in value.
Part2:
equation can Miguel set up to solve for the annual interest rate he needs to double his money by the time he retires is n = 72 / r
Part3:
annual interest rate does Miguel need to double his money by the time he retire

Explain about the quadratic equation?In mathematics, a quadratic equation is one with degree 2, which means that its maximum exponent is 2. A quadratic has the standard form y = ax2 + bx + c, where such a, b, and c are all numbers which can't be zero. All of these are examples of quadratic equations:Th equation is-
y = -1.2x² + 3.12x +3.
horizontal distance - x
Part A: distance travelled by athlete when she reaches her maximum:
Comparing given equation with standard form of quadratic equation:
x = -b/a
x = -3.12/2(-1.2) = 1.3
Thus, distance travelled by athlete when she traveled horizontally and reaches her maximum of 1.3 m.
Part B: her maximum height:
y = -1.2x² + 3.12x +3.
Put x = 1.3
y = -1.2(1.3)² + 3.12(1.3) +3.
On solving:
y = 5.028
y = 5 m
Thus, her maximum height, round to the nearest tenth of a meter is 5 m.
