Bill Campbell gets a student rate for medical insurance of $25.00 a month. There is a $250 deductible.
He recently received treatment for a covered condition. The bill was $2,350.00
Bill's insurance company provided payment of 80% of the bill less the deductible.
What was the insurance company's payment? $
What was Bill's share of the charge? $
The insurance company's payment is $1,680.00 and Bill's share of the charge is $670.00.
Explanation:To calculate the insurance company's payment, we first need to determine the amount after the deductible is applied. Since the bill was $2,350.00 and the deductible is $250, we subtract the deductible from the bill: $2,350.00 - $250 = $2,100.00. The insurance company covers 80% of this amount, so we multiply $2,100.00 by 80%: $2,100.00 x 80% = $1,680.00. Therefore, the insurance company's payment is $1,680.00.
Bill's share of the charge is calculated by subtracting the insurance company's payment from the total bill: $2,350.00 - $1,680.00 = $670.00. Therefore, Bill's share of the charge is $670.00.

Two passenger train, A and B, 450 km apart, star to move toward each other at the same time and meet after 2hours.
If train B, travels 8/7 as fast as train A. Find the speed of each train
Let [tex]v[/tex] be the speed of train A, and let's set the origin in the initial position of train A. The equations of motion are
[tex]\begin{cases}s_A(t) = vt\\s_B(t) = -\dfrac{8}{7}vt+450\end{cases}[/tex]
where [tex]s_A,\ s_B[/tex] are the positions of trains A and B respectively, and t is the time in hours.
The two trains meet if and only if [tex]s_A=s_B[/tex], and we know that this happens after two hours, i.e. at [tex]t=2[/tex]
[tex]\begin{cases}s_A(2) = 2v\\s_B(2) = -\dfrac{16}{7}v+450\end{cases}\implies 2v = -\dfrac{16}{7}v+450[/tex]
Solving this equation for v we have
[tex]2v = -\dfrac{16}{7}v+450 \iff \dfrac{30}{7}v=450 \iff v=\dfrac{450\cdot 7}{30} = 105[/tex]
So, train A is travelling at 105 km/h. This implies that train B travels at
[tex]105\cdot \dfrac{8}{7} = 15\cdot 8=120 \text{ km/h}[/tex]
train A travels at 210 km/h and train B travels at 240 km/h.
The student's question involves finding the speeds of two trains moving towards each other when certain conditions are provided. We know that the two trains are 450 km apart and meet after 2 hours. Train B travels at 8/7 the speed of train A.
Let's denote the speed of train A as v km/h. Then, the speed of train B would be 8/7 * v km/h. Since they meet after 2 hours, we can add their distances to equal the total distance between them.
Speed of train A: v km/h
Speed of train B: 8/7 × v km/h
Total distance: 450 km
Time to meet: 2 hours
The total distance both trains cover can be expressed as:
(Speed of train A + Speed of train B) × Time = (v + 8/7 × v) × 2 hours
Since the sum of the two distances covered by the trains is the initial distance between them which is 450 km, we get:
(1 + 8/7)v * 2 = 450 km
We simplify this equation to find the value of v. The equation becomes:
15/7 v × 2 = 450 km
v = (450 × 7) / (15 × 2)
v = 210 km/h
Now, we find the speed of train B by multiplying the speed of train A by 8/7:
Speed of train B = 8/7 × 210 km/h = 240 km/h
Therefore, train A travels at 210 km/h and train B travels at 240 km/h.
a restaurant uses 60 cups of mushrooms to make 12 gallons of mushroom soup. jesse wants to make 3 gallons of soup using this recipe. how many cups of mushrooms should he use?
Answer:
15
Step-by-step explanation:
Write a proportion:
60 cups / 12 gallons = x cups / 3 gallons
Cross multiply:
12x = 180
Divide:
x = 15
He should use 15 cups.
Jesse should use 15 cups of mushrooms to make 3 gallons of mushroom soup, based on the restaurant's recipe. Devon will be making 37.5 liters of soup for the party of 100 guests.
Explanation:To solve Jesse's question about how many cups of mushrooms he should use to make 3 gallons of mushroom soup, we need to find the proportion between the amount used in the restaurant's recipe and the desired amount for Jesse's smaller batch.
The restaurant uses 60 cups of mushrooms to make 12 gallons of soup. To find out how many cups are needed for 1 gallon, we divide the number of cups by the number of gallons:
60 cups / 12 gallons = 5 cups per gallon
Jesse wants to make 3 gallons of soup. Multiplying the amount needed for one gallon by 3 gives us the answer:
5 cups/gallon × 3 gallons = 15 cups of mushrooms.
Devon, on the other hand, is preparing soup for a party. Calculating the total amount for 100 guests using 375 milliliters per person, we get:
375 milliliters/guest × 100 guests = 37500 milliliters.
Since 1 liter is equivalent to 1000 milliliters, we can convert the milliliters to liters:
37500 milliliters / 1000 = 37.5 liters of soup for 100 guests.

You are doing yardwork with a friend. You can finish mowing the lawn in 57 minutes, while your friend can do the same amount of work in 54 minutes. How long will it take to complete the job if you work together? Round your answer to the nearest whole number.
Answer:
28 minutes
Step-by-step explanation:
Speed = distance / time
Your speed is 1 lawn / 57 minutes. Your friend's speed is 1 lawn / 54 minutes. Working together, your combined speed is:
1/57 + 1/54
So the time it takes working together is:
Speed = distance / time
1/57 + 1/54 = 1 / t
t = 27.7 minutes
Rounded to the nearest whole number, it takes 28 minutes.

Mrs. Karabin wants to paint the inside of her brand new two-car garage. The garage is 20 feet wide, 24 feet long, and 12 feet tall. She wants to paint the walls and the ceiling (not the floor). What’s the surface area of the parts she wants to paint?
Answer:
The surface area is [tex]1,536\ ft^{2}[/tex]
Step-by-step explanation:
we know that
The surface area is equal to
[tex]SA=B+PH[/tex]
where
B is the area of the ceiling
P is the perimeter of the base
H is the height of the walls
substitute the given values
[tex]SA=(20)(24)+2(20+24)(12)[/tex]
[tex]SA=480+1,056=1,536\ ft^{2}[/tex]
Mrs. Karabin will be painting a total of 1536 square feet in her garage. This includes 1056 square feet for the walls and 480 square feet for the ceiling.
Explanation:To solve this, we need to calculate the surface area for the walls and ceiling of the garage. Because all sides of this garage are rectangular, we can find the area by multiplying the length by times width for each side.
For the walls: There are two walls that are 12 feet high and 24 feet long and two walls that are 12 feet high and 20 feet wide. So, we calculate (12x24)x2 + (12x20)x2 = 576 + 480 = 1056 square feet.
For the ceiling: The ceiling is 20 feet wide and 24 feet long, so we calculate 20x24 = 480 square feet.
Adding these together, Mrs. Karabin will be painting 1056 (for the walls) + 480 (for the ceiling) = 1536 square feet in total.

Step-by-step explanation:
bc is along a straight line with section 4 straight lines are 180° if bc is 30° then 180°-30°=150°
Answer:
The measure of ∠4 is 150°
Step-by-step explanation:
Given the figure in which BD is the diameter of circle and
m∠1=100°
m(arc BC)=∠3=30°
we have to find the measure of ∠4.
As BD is a straight line as BD is diameter therefore
∠4 and ∠3 forms a linear pair
⇒ ∠4 and ∠3 are supplementary i.e these angles adds up to 180°
∠4 + ∠3 = 180°
∠4+30°=180°
∠4=180°-30°=150°
Hence, the measure of ∠4 is 150°

Area of the wall is given by = width × height
Given width of room = 12' and height of wall =9 feet
Area for one wall= 12×9=108ft²
Area for four walls= 108 × 4=432ft²
Answer:
They will cover 432 feet²
Step-by-step explanation:
* Lets study the information in the problem
- The room has floor with dimensions 12 feet by 12 feet
- The height of the room is 9 feet
- The room has floor and ceiling with same dimensions
- The room has four walls with dimensions 12 feet and 9 feet
- The need to cover the 4 walls
- Each wall shaped a rectangle with base 12 feet and height 9 feet
- The area of the rectangle = base × height
* Now lets solve the problem
∵ The base of the wall = 12 feet
∵ The height of the wall = 9 feet
∵ The area of the wall = base × height
∴ The area of one wall = 12 × 9 = 109 feet²
- The room has four identical walls
∴ The area of the 4 walls = 4 × 108 = 432 feet²
* They will cover 432 feet²

These are basically 3 problems, so I won't explain two items for every one of your 13 similar questions. Here's the explanation for every 3 cases asked in your questions... and the answers. All you have to do is replace the numbers in the explanations for the ones in each other question asking the same thing.
To express a fraction in percentage, you simply have to put the fraction with a denominator of 100..., for example:
[tex]\frac{1}{20} * \frac{5}{5} = \frac{5}{100}[/tex]
So, 1/20 is 5%.
[tex]\frac{1}{2} * \frac{50}{50} = \frac{50}{100}[/tex]
And 1/2 is 50%
To express a percentage as a fraction, you take that percentage and place it over a denominator of 100 and you simplify, like this:
[tex]\frac{12.5}{100} = \frac{1}{8}[/tex]
[tex]\frac{30}{100} = \frac{3}{10}[/tex]
To convert a decimal number to a fraction, the easiest way is to express this number up to the 2nd decimal... then take that as a %.
Examples:
0.2 you can say 0.2 = 0.20... so it's 20 hundredths, or 20 per 100... so 20%
0.375, it's already expressed in more than hundredths, so you simply move the dot 2 spots right to get 37.5%
what is 1/20 as a decimal and a percentage: 5% (see above)
what 1/10 as a decimal and a percentage : 10% (save as above)
what 12 1/2% as a decimal and a percentage: 12.5%, it's already as a percentage, if you mean as a fraction... 1/8 (see above)
what is 0.2 as a fraction and a percentage: 1/5 and 20% (see above)
what is 25% as a decimal and fraction: 0.25 and 1/4
what is 30% decimal and fraction : 0.3 and 3/10

2. For f(x) = 2(x+3) - 5, name the type of function and describe each of the
three transformations from the parent function f(x) = x
Answer:
The function is a linear function
The function is translated 3 units to the left,then stretched vertically
by factor 2, then translated 5 units down
Step-by-step explanation:
* Lets revise some transformation
- If the function f(x) translated horizontally to the right
by h units, then the new function g(x) = f(x - h)
- If the function f(x) translated horizontally to the left
by h units, then the new function g(x) = f(x + h)
- If the function f(x) translated vertically up
by k units, then the new function g(x) = f(x) + k
- If the function f(x) translated vertically down
by k units, then the new function g(x) = f(x) – k
- If the function f(x) stretched vertically, then g(x) = k · f(x), where
k > 1 (multiplying each of its y-coordinates by k)
- If the function f(x) compressed vertically, then g(x) = k · f(x), where
0 < k < 1 (multiplying each of its y-coordinates by k)
* Now lets solve the problem
∵ f(x) = 2(x + 3) - 5
- The greatest power of the function is 1 (degree of the function)
∴ f(x) is linear function
- The parent function f(x) = x
∵ f(x) changed to f(x + 3)
∴ f(x) translated 3 units to the left
# Each x-coordinate of the points on the function subtracted by 3
∵ f(x + 3) changed to 2f(x + 3)
∵ 2 > 1
∴ f(x + 3) stretched vertically by factor 2 (k = 2)
# Each y-coordinate of the points on the function multiplied by 2
∵ 2f(x + 3) changed to 2f(x + 3) - 5
∴ 2f(x + 3) translated 5 units down
# Each y-coordinate of the points on the function subtracted by 5

6[tex]x^{4}[/tex] - 5x² + 12x² - 10 ( factor the first/second and third/fourth terms )
= x²(6x² - 5) + 2(6x² - 5) ← factor out (6x² - 5) from each term
= (6x² - 5)(x² + 2)
Answer:
(x^2 + 2)(6x^2 – 5)
Step-by-step explanation:
6x^4 – 5x^2 + 12x^2 – 10
=(6x^4 – 5x^2) + (12x^2 – 10)
=x^2 (6x^2 – 5) + 2(6x^2 – 5)
=(x^2 + 2)(6x^2 – 5)
Answer
(x^2 + 2) and (6x^2 – 5) are factors of the expression 6x^4 – 5x^2 + 12x^2 – 10
Ryan has a school bag. He has 6 books, of which 2 are math books. What is the probability that a randomly selected book will be a math book?
1/3
2 of the books are math books and there are 6 books. This is 2/6. Now, divide both sides of the fraction by 2 to simplify it. This gives you a final answer of 1/3.
