The percentage decrease in a price is 37 percent.

Percentage is defined as a given part or amount in every hundred. It is a fraction with 100 as the denominator and is represented by the symbol "%".

Given that, in January 2015 the price of gas was on average $2.05 per gallon this was $1.20 cheaper than a year.

Cost of gas per gallon = 2.05+1.20

= $3.25

Now, Percentage decrease = (Original Price - New Price)/Original Price ×100

= (3.25-2.05)/3.25 ×100

= 1.20/3.25 ×100

= 0.3692×100

= 0.37×100

= 37%

Therefore, the percentage decrease in a price is 37 percent.

Answer:

total tax is = 14685 pound

Step-by-step explanation:

Given data:

For first year -  

earning is 11000 pound

for second year

income is = 43000 - 11000 = 32000 pound

tax rate = 20%

for third year

income is = 150000 - 43000 = 107000 pound

tax rate = 40%

for fourth year

income is = 158900 - 150000 = 8900 pound

tax rate = 45%

As it is given there is no tax on first year

Tax in 2nd year  = 0.20 × 32000 = 6400 pound

Tax in 3rd year  = 0.40 × 107000 = 42800 pound

Tax in 4th year  = 0.45 × 8900 = 4005 pound

Step-by-step explanation:

The mean number of candy bars needed to find a golden ticket is 1/p, and the variance is (1-p)/p^2.

To find the mean and variance of the number of candy bars you need to eat to find a golden ticket, we need to use the concept of a geometric distribution. The geometric distribution models the number of trials it takes to achieve a success, where each trial has the same probability of success.

The mean of a geometric distribution is given by μ = 1/p, where p is the probability of success. In this case, p represents the probability of finding a golden ticket. Therefore, the mean number of candy bars needed to find a golden ticket is 1/p.

The variance of a geometric distribution is given by σ^2 = (1-p)/p^2. This represents the spread or variability in the distribution. Using the given value of p, you can calculate the variance of the number of candy bars needed to find a golden ticket.

The smaller number is 13 and the larger number is 25, as determined by solving the given equations.

Let's denote the smaller number as x. According to the given information, the larger number is 12 more than the smaller number, so we can represent the larger number as x + 12.

We are also told that the sum of the two numbers is 38. This can be expressed as the equation x + (x + 12) = 38.

Combining like terms, we simplify the equation to 2x + 12 = 38.

Next, we subtract 12 from both sides to isolate 2x: 2x = 26.

To solve for x, we divide both sides of the equation by 2: x = 13.

So, the smaller number is 13.

To find the larger number, we substitute the value of x into the expression x + 12: 13 + 12 = 25.

Therefore, the larger number is 25.

Answer:  $175.63.

Step-by-step explanation:

As  per given ,

Past due balance = $87.50

New Charge = $75

Late fee charge = (15% ) of ( Past due balance )

=   0.15 x ($87.50)

=  $ 13.125 ≈ $ 13.13  [Round off to the nearest cent]

Now , the new total = (Past due balance)+(New Charge )+(Late fee charge)

i.e. New total = ($87.50)+($75)+($13.13)

i.e. New total = $175.63

Hence, the new total is $175.63.

The Area of the rectangle is 45 square feet.

The perimeter of a form is the space surrounding its edge. To Find the perimeter of various forms by summing the lengths of their sides.

Given, The length of a rectangle is 4 ft longer than its width. If the perimeter of the rectangle is 28 ft.

Let "l" be the length of the perimeter

Thus, width = l - 4

From the general formula of perimeter:

perimeter = 2*(length + width)

In our case

Perimeter = 2* (l + l -4)

Perimeter = 4l - 8

Since the perimeter is given 28 ft

thus,

4l - 8 = 28

4l = 36

l = 9 ft

thus width = 9 - 4 = 5 ft

Since,

Area = Length * width

Area = 9 * 5

Area of rectangle = 45 square feet.

therefore, The Area of the rectangle is 45 square feet.

Answer:

D They must have common denominators.

Step-by-step explanation:

Rational expressions are fractions formed by two polynomials, one in the numerator and other in the denominator.

The numerator is the polynomial that is at the top of the fraction and denominator is the polynomial that is at the bottom of the fraction.

To add any fractions it is necessary that they have the same denominator, this applies to rational expressions, to add them it is required that they have the same polynomial in the denominator.

The function f(g(x)) is ((x^10+1)^(9/2), the derivative f'(u) is (9/2)u^(7/2), the derivative f'(g(x)) is (9/2)(x^10+1)^(7/2), the derivative g'(x) is 10x^9, and the derivative (f ∘ g)'(x) is the product of g'(x) and f'(g(x)) which equals to 10x^9 * (9/2)(x^10+1)^(7/2).

The functions are defined as f(u)=u9/2 whereas g(x)=x10+1.

To find f(g(x)), input g(x) into the f function. Thus, f(g(x))=((x10+1)9/2.

Next, the derivative of f(u) would be: f'(u)= (9/2)u7/2.

For f'(g(x)), replace u with g(x) in f'(u): f'(g(x))=(9/2)(x10+1)7/2.

The derivative of g(x) is: g'(x)=10x9.

Lastly, to find (f ∘ g)'(x), use the chain rule which states that (f ∘ g)'(x) = g'(x) * f'(g(x) : (f ∘ g)'(x) = 10x9 * (9/2)(x10+1)7/2.

Answer: 48 ounces

Step-by-step explanation: To convert 3 pounds into ounces, we first need to identify the conversion factor for pounds and ounces, which is shown below.

16 ounces = 1 pound

We are going from a larger unit, pounds, to a smaller unit, ounces.

When we go from a larger unit to a smaller unit, we multiply.

So here, we multiply 3 lb x 16 which gives us 48 ounces.

Note that I multiplied by the conversion factor.

This means that the fruit salad is 48 ounces.

Final answer:

The student should invest $60,000 in the CD at 7% annual interest and $80,000 in the mutual fund at 10% to earn a total interest of $12,200 in one year. This is determined by setting up and solving a system of linear equations.

Explanation:

The student asked how much money should be invested in a CD at 7% annual interest and a mutual fund with a three-year average annual interest of 10%, given a total investment of $140,000, to earn a total of $12,200 in one year. We can set up a system of equations to solve for X (the amount invested in the CD) and Y (the amount invested in the mutual fund).

Let X be the amount invested in the CD and Y be the amount invested in the mutual fund. We then have the following system of equations:

Solving this system, we subtract the first equation from the second equation multiplied by 0.07:

Subtract the second equation from the first we get:

0.03Y = $2,400

Dividing both sides by 0.03 gives:

Y = $80,000

Substitute Y in the first equation:

X + $80,000 = $140,000

X = $140,000 - $80,000 = $60,000

Therefore, $60,000 should be invested in the CD and $80,000 in the mutual fund to obtain a total interest of $12,200 in one year.

The inequality 834 + 14s > 978 - 10s can represent a situation involving saving and spending money over time. To solve it, you perform a series of operations to isolate variable 's', which in this case results in s > 6, indicating more than six weeks required for savings to exceed spending.

A real world situation that can be modelled by this inequality 834 + 14s > 978 - 10s could be a scenario involving saving and spending money. Say you start with $834 and each week you save $14 (s represents the number of weeks). On the other hand, you have $978 and you spend $10 each week. You want to figure out how many weeks it will take for the amount you have from saving to be more than the amount left from spending.

Now, to solve the inequality: subtract 834 from both sides which gives 14s > 144 - 10s, then combine like terms to get 24s > 144. Finally, divide both sides by 24 to solve for s: s > 6. Therefore, it will take more than six weeks for the money you save to exceed what remains from your starting amount of $978 after spending $10 each week.
