A musician on tour exchanges American dollars for British pounds. The equation y = 1.25 x models the relationship between pounds ( x ) and dollars ( y ). Positive numbers represent bank deposits, and negative numbers represent bank withdrawals.

The weight of the plane if it is carrying gallons of fuel is 2336 pounds, under the condition of when carrying 10 gallons, and 45 gallons he airplane weighs 2056  and 2252 pounds.
We can utilize the two given points to create two linear equations

y = mx + b
2056 = 10m + b
2252 = 45m + b

We can find m and b by subtracting the first equation from the second equation:

(45m + b) - (10m + b) = 2252 - 2056
35m = 196
m = 5.6

For finding b by substituting m into one of the original equations:

2056 = 10(5.6) + b
b = 2000

The equation is

y = 5.6x + 2000

To evaluate  how much the airplane weighs when carrying 60 gallons of fuel,  now lets substitute x into the equation

y = 5.6(60) + 2000
y = 336 + 2000
y = 2336

When carrying 10 gallons of fuel, the airplane weighs 2056 pounds. When carrying 45 gallons of fuel, it weighs 2252 pounds. How much does the airplane weigh if it is carrying 60 gallons of fuel?

Answer:

Step-by-step explanation:

I think it’s b

Part A

According to the equation, the values of a is a = 2009 + f(a) and b is b = 800 + f(b).

Part B

Approximately it takes 8 years from 2009 for the population of wild tigers in Nepal to reach 800.

To find these values, we need to set the equation for the population of wild tigers equal to 800 and solve for x. The equation becomes 800 = 121(2)ˣ.

Taking the logarithm of both sides, we get

=> log(800) = log(121) + x log(2).

Solving for x, we get

=> x = (log(800) - log(121))/log(2).

Moving on to the second part of the problem, we are asked to determine approximately how many years from 2009 it will take for the population of wild tigers in Nepal to reach 800. Using the equation we derived in Part A, we can plug in values of a and use trial and error to find the answer. However, this can be time-consuming.

Instead, we can use a calculator to get an approximate answer. Plugging in the values for log(800) and log(121) into the equation we derived in Part A, we get x = 7.75.

Therefore, it will take approximately 8 years from 2009 for the population of wild tigers in Nepal to reach 800.

the probability of rolling two 3's is 1/36.Since we are rolling two number cubes, the sample space contains 6x6 = 36 equally likely outcomes, one for each possible pair of numbers that can be rolled.

what is probability  ?

Probability is a measure of the likelihood of an event occurring. It is a number between 0 and 1, where 0 represents an impossible event and 1 represents a certain event. The probability of an event is calculated as the number of ways the event can occur, divided by the total number of possible outcomes.

In the given question,

Since we are rolling two number cubes, the sample space contains 6x6 = 36 equally likely outcomes, one for each possible pair of numbers that can be rolled.

To find the probability of rolling two 3's, we need to count the number of outcomes that result in two 3's, and divide by the total number of possible outcomes.

From the diagram, we can see that there is only one outcome that results in two 3's, namely the outcome where the first cube shows a 3 and the second cube shows a 3. Therefore, the number of favorable outcomes is 1.

The probability of rolling two 3's is therefore:

P(rolling two 3's) = favorable outcomes / total outcomes = 1/36

So the probability of rolling two 3's is 1/36.

the area of the rhombus is approximately 74.60 square units.

How to solve the question?

To find the area of a rhombus using decomposition, we first need to draw its diagonal lines. Let's label the points where the diagonals intersect as points A and B.

Now we can decompose the rhombus into two congruent triangles, ABC and ABD, where AB is the diagonal and AD and BD are half of the diagonals.

We can find the length of AD and BD using the Pythagorean theorem. Since x=4 units and y=6 units, we have:

AD²= (x/2)² + h²

AD² = (4/2)²+ 5²

AD²= 4² + 5²

AD² = 41

AD = sqrt(41)

Similarly, we can find the length of BD:

BD²= (y/2)² + h²

BD²= (6/2)² + 5²

BD²= 3²+ 5²

BD²= 34

BD = √(34)

Now we can find the area of each triangle:

Area of ABC = (AB * BD) / 2

Area of ABC = (2 * √(41) * √(34)) / 2

Area of ABC = √(1394)

Since the rhombus is made up of two congruent triangles, its total area is twice the area of one triangle:

Area of rhombus = 2 * Area of ABC

Area of rhombus = 2 * √(1394)

Area of rhombus ≈ 74.60 square units

Therefore, the area of the rhombus is approximately 74.60 square units.

the value of f(6) is -972.To understand why f(6) is equal to -972, we can think of the recursive formula as a process that generates a sequence of numbers. Starting with f(1) = 4, we can apply the formula repeatedly to generate the sequence:

4, -12, 36, -108, 324, -972, ...

How to solve the question?

We can use the recursive formula given to find the value of f(6). Let's start by calculating f(2):

f(2) = -3f(1) = -3(4) = -12

Next, we can calculate f(3) using the same formula:

f(3) = -3f(2) = -3(-12) = 36

We can continue this process for f(4) and f(5):

f(4) = -3f(3) = -3(36) = -108

f(5) = -3f(4) = -3(-108) = 324

Finally, we can use the formula to find f(6):

f(6) = -3f(5) = -3(324) = -972

Therefore, the value of f(6) is -972.

To understand why f(6) is equal to -972, we can think of the recursive formula as a process that generates a sequence of numbers. Starting with f(1) = 4, we can apply the formula repeatedly to generate the sequence:

4, -12, 36, -108, 324, -972, ...

Each term in the sequence is obtained by multiplying the previous term by -3. We can see that the sequence alternates between positive and negative values, with the magnitude of each term growing rapidly. By the time we reach f(6), the magnitude has grown to 972, and the negative sign indicates that the term is negative. Thus, f(6) is equal to -972.

Rounding to the nearest cent, the cost of the utility pole is $2,061.33 with a diameter of 1. 5 ft and a height of 45 ft.

To calculate the cost of a utility pole, we first need to find its volume, which is the product of its height and the cross-sectional area of its base. Since the pole is in the form of a right cylinder, the cross-sectional area of its base is a circle with radius equal to half the diameter, which is 0.75 ft. Therefore, the cross-sectional area is:

Area = πr^2 = π(0.75)^2 = 1.767 ft^2

The volume of the pole is then:

Volume = Area x Height = 1.767 x 45 = 79.515 ft^3

Answer: the height of the hockey puck is approximately 0.835 inches.

Step-by-step explanation: The formula for determining the volume of a cylinder is as follows:

The formula for the volume (V) of a cylinder can be expressed mathematically as V = πr2h, where r represents the radius of the cylinder's base and h represents the height of the cylinder. This formula is derived from the concept that the volume of a cylinder can be calculated by multiplying the area of its base (which is represented by the term πr2) by its height (h).

The present study utilizes the conventional nomenclature in which V denotes the volume, r represents the radius, and h stands for the height.

As the diameter of the hockey puck is measured to be 3 inches, it follows that the radius is equivalently calculated as 1.5 inches, or precisely half of the diameter.

It is established that the hockey puck has a volume of 7.1 cubic inches; accordingly, by substituting these known values into the relevant formula and performing the appropriate calculations, the measurement of h may be ascertained.

The expression 7.1 = π(1.5)^2h can be reformulated in a more academic manner. It can be said that the equation represents the mathematical relationship between the volume of a cylinder and its dimensions, wherein the value of 7.1 denotes the volume of the cylinder, whereas π, 1.5, and h refer to the mathematical constants of pi, radius, and height, respectively. Thus, the formula can be expressed as V = πr^2h, where V represents the volume of the cylinder, r denotes the radius, and h denotes the height.

As such, it can be represented by the following expression: 2.25πh = 7.1

Dividing each side by 2.25π is a logical mathematical operation utilized to simplify an equation or expression.

The aforementioned equation may be expressed in an academic tone as follows: The value of h is equivalent to the quotient obtained from dividing 7.1 by 2.25 times the mathematical constant π.

Step-by-step explanation:

Billy is in a pickle. He has a credit card debt of $3500 with a 16% annual interest rate, and he wants to pay it off in a year. He also wants to ask his boss for a raise, but he doesn't know how much to ask for. Luckily, he has a friend who is good at math and can help him out.

The friend tells Billy that we need to use the formula for the monthly payment of a credit card debt, which is:

P = (r / 12) * B / (1 - (1 + r / 12)^(-n))

where P is the monthly payment, r is the annual interest rate, B is the current balance, and n is the number of months to pay off the debt.

Using this formula, the friend calculates how much Billy is currently paying and how much he would need to pay to clear his debt in 12 months. The friend also finds the difference between these two payments, which is the amount of extra income Billy would need from his raise.

The friend shows Billy the calculations and says:

"Here you go, Billy. You are currently paying $280.42 per month to pay off your debt in 15 months. If you want to pay it off in 12 months, you would need to pay $331.79 per month. That means you would need an additional monthly income of $51.37 from your raise. The closest answer choice to this amount is a. $58.57, so this is the best option."

Step-by-step explanation:

Given angles 5 and 8 where line c crosses line a, you want to know what type they are.

Where two lines cross, four angles are formed. They all share the vertex point where the lines intersect. If they share a side (and no interior space), they are adjacent angles that form a linear pair. As such, they are supplementary.

In the given figure the supplementary angle pairs where line c crosses line a are ...

  (5, 6), (6, 8), (7, 8), (5, 7)

If the angles do not share a side, but are formed from opposite rays, they are "vertical angles" and are congruent.

The vertical angle pairs there are ...

  (5, 8), (6, 7)

Angles 5 and 8 are vertical angles, choice C.

__

Additional comment

Angle pairs (1, 8) and (2, 7) are "alternate exterior angles." Angle pairs (3, 6) and (4, 5) are "alternate interior angles."

Assuming lines b and c are parallel, considering also angles where line b crosses line a, there are additional supplementary pairs of angles:

  (1, 2), (2, 4), (3, 4), (1, 3), (1, 6), (1, 7), (2, 5), (2, 8), (3, 5), (3, 8), (4, 6), (4, 7)

When parallel lines are crossed by a transversal, all of the acute angles are congruent, all of the obtuse angles are congruent, and the acute angles are supplementary to the obtuse angles. The angles are referred to by different names (and different theorems), depending on where they are in relation to the transversal and the parallel lines.
