The total cost of a prescription is $119.25. Mr. Jones's co-insurance plan requires him to contribute 15 percent of the cost. What's Mr. Jones's out-of-pocket cost for this prescription?
Answers
To find Mr. Jones's out-of-pocket cost for his prescription, calculate 15% of the total cost of $119.25, resulting in $17.89 after rounding.
Explanation:The question asks us to calculate Mr. Jones's out-of-pocket cost for his prescription if his co-insurance plan requires him to pay 15% of the total cost. The total cost of the prescription is $119.25.
To find out Mr. Jones's out-of-pocket expense, we calculate 15% of $119.25:
Out-of-pocket cost = 15% of total cost
= 0.15 × $119.25
= $17.8875
So, Mr. Jones's out-of-pocket cost will be $17.8875, which we can round to $17.89 for practical purposes.

Avi's pet hamster Chubby loves to run in his hamster wheel. During one "race", Avi counts 100 rotations of the wheel. She wants to know how far Chubby ran, so she measures the diameter of the wheel and finds that it is 8 inches. How far did Chubby run? Give your answer in terms of pi. (prize is 99 points)
Answers
=======================================
Explanation:
The formula to find the circumference of a circle is
C = pi*d
where
C = distance around the circle (aka circumference)
pi = 3.14 approximately
d = diameter
We know that the diameter of the wheel is d = 8, so
C = pi*d
C = pi*8
C = 8pi
is the circumference of the wheel
One full rotation will have the wheel cover a distance of 8pi inches. Imagine that wet paint is on the outer surface of the wheel. If the wheel is rolled out in a straight line, then the wet paint would cover a linear distance of 8pi inches along the flat ground. This is one full rotation, so 100 rotations covers 100*8pi = 800pi inches
Note: if we use pi = 3.14 as the approximation, then the hamster ran approximately 800*pi = 800*3.14 = 2512 inches if the wheel could move

Answer: B) 25
Step-by-step explanation:
Given: A rectangular dartboard has an area of 648 square centimeters.
The triangular part of the dartboard has an area of 162 square centimeters.
If a dart is randomly thrown at the dartboard. Assuming the dart lands in the rectangle, the probability (in percent) that it lands inside the triangle will be :

Caleb bought a car for $6,900. He agreed on a five-year loan at a 5.4% interest rate. Calculate what Caleb's monthly payments will be.
Answers
To calculate Caleb's monthly car payments, use the loan amortization formula that deals with compound interest, not simple interest. Input the loan amount of $6,900, the monthly interest rate (annual rate of 5.4% divided by 12), and the total number of payments (5 years times 12 payments per year) into the formula to find the monthly payment.
Explanation:Caleb's car loan scenario comes under financial mathematics, specifically, it deals with loan amortization using the concept of compound interest. Since the car loan spans multiple years, compound interest is the accurate model to use, not simple interest. As opposed to simple interest which only accrues on the original amount or principal, compound interest accrues on the principal and all interest previously added.
The formula to calculate the monthly payment, P, on a loan is given by, where PV represents t
[tex]P = [r*PV] / [1 - (1 + r)^-n][/tex]he present value or the amount of loan, which is $6,900 in this case; r is the monthly interest rate which can be calculated as annual interest rate divided by 12, translating to 0.054/12 in this case; and n is the total number of payments (i.e., 5 years of payments with 12 payments per year, hence, 5*12).
To calculate the monthly payment, plug these values into the formula which should give you the monthly payment amount that Caleb needs to pay for his car loan.

In a woodworking you are planing boards to make shelves. The planer is set to remove 1/16 inch from a board on each pass the board makes through the planer. If a board starts out at 3/4 inch thick, how many times will you need to send it through the planer to get it down to 5/8 inch?
Answers
Initial thickness = 3/4 in
Final thickness = 5/8 in
If x is the number of passes,
The material removed = (1/16)x in.
Therefore,
3/4 - (1/16)x = 5/8
3/4 - x/16 = 5/8
x/16 = 3/4 - 5/8 = 1/8
x = 16*1/8 = 2
Therefore, the board will be passed through the plane twice.

3 sides and 1 angle. So if the known properties of a triangle are SSS (side-side-side) or SAS (side-angle-side), then this law applies.
If you want the ratio of the sine of an angle and its inverse to be equal, you can use the law of sine. This can be used if the triangle's known properties are ASA (angle-side-angle) or SAS.
Using Law of sine:
40/sin 68 = 43/sin Z
sin Z = (43/40) * sin 68
sin Z = 0.9967
Z = sin⁻¹0.9967
Z = 85.3°
The only option with the correct value of angle Z is Option D with:

If the train that Megan is riding covers 80 miles in 2 hours, how fast is the train traveling?
Answers
To find this, you divide both 80 and 2 by 2 to find how many miles in a single hour the train travels. Thus giving you 40 miles in an hour (40 mph) as a ginal answer.
I hope this helps!
Final answer:
The average speed of the train Megan is traveling on is 40 miles per hour. It's obtained by dividing the total distance of 80 miles by the total time of 2 hours.
Explanation:
To find the average speed of the train that Megan is riding, which covers 80 miles in 2 hours, we will use the formula for average speed, which is total distance divided by total time. The train travels 40 miles one way and 40 miles back, totaling 80 miles.
Here is the step-by-step calculation:
Calculate the total distance the train travels: 40 miles one way + 40 miles back = 80 miles.
Calculate the total time of the journey: 2 hours.
Divide the total distance by the total time to find the average speed: 80 miles / 2 hours = 40 miles per hour.
This means the average speed of the train is 40 miles per hour.

Hope this Helps!!
The length of the hypotenuse of the triangle is √58 cm (Option D).
To find the length of the hypotenuse of a right triangle, we can use the Pythagorean theorem, which states that the square of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the other two sides.
Let's label the sides of the triangle:
Side a = 7 cm (one of the legs)
Side b = 3 cm (the other leg)
Side c = ? (the hypotenuse)
The Pythagorean theorem is:
[tex]c^2 = a^2 + b^2[/tex]
Substitute the given values:
[tex]c^2 = 7^2 + 3^2\\\\c^2 = 49 + 9\\\\c^2 = 58[/tex]
Now, we can find the square root of both sides to solve for c:
c = √58 cm
So, the length of the hypotenuse of the triangle is √58 cm.
The correct answer is: D. √58 cm
