The correct linear equation that shows the relationship between the two types of wood purchased by the contractor is option A. 45(x+3)=60x.

Let's break down the problem,

The contractor purchased 45 units of expensive wood and 60 units of cheap wood for the same total price.

Let's assume that the price of the 60 units of cheap wood is x.

According to the problem, 45 units of expensive wood cost $3.00 more per unit than 60 units of cheap wood. This means that the price of the 45 units of expensive wood is (x+3).

Now, we can set up the equation,

The total cost of 45 units of expensive wood + Total cost of 60 units of cheap wood = Total cost of wood purchased

45(x+3) + 60(x) = 105(x)

Simplifying this equation, we get:
45x + 135 + 60x = 105x
105x = 135
x = 1.29

Therefore, the price of the 60 units of cheap wood is $1.29, and the price of the 45 units of expensive wood is $4.29.

Substituting the value of x in option A, we get:
45(x+3) = 45(1.29+3) = 45(4.29) = 193.05
60x = 60(1.29) = 77.4

Total cost of wood purchased = 193.05 + 77.4 = 270.45

This confirms that option A is the correct linear equation that shows the relationship between the two types of wood purchased.

Store revenue will be maximised, if they charge 7 dollars for each movie rental.

The entire amount of money received by an organisation's operations over a predetermined period of time is the basic definition of revenue.

A company's revenue is its total revenue before any expenses are subtracted. According to the definition, revenue is the total sum of money obtained through conducting commercial activities like sales.

Let store charge x $ for each movie.

No.of rented movies per weak = 108-9x(x-z)

Total revenue = x*[108-9(x-2)]

= x*[108-9x+18]

= x*[126-9x]

= 126x-9x^2

Total revenue will be maximised when dT/dx = 0

dT/dx = 126-9*2x

= 126-18x = 0

18x = 126

x = 7$

The fraction that we need to subtract from 3/4 to get 2/3 is 1/12.

Let's use x to represent the fraction that we need to subtract from 3/4 to get 2/3.

We can set up an equation:

3/4 - x = 2/3

3/4 - x = 2/3

x = 2/3 - 3/4

To subtract these fractions, we need to find a common denominator. The least common multiple of 3 and 4 is 12, so we can rewrite the fractions with a denominator of 12:

x = (2/3) * (4/4) - (3/4) * (3/3)

x = 8/12 - 9/12

Now we can combine the fractions:

x = -1/12

Therefore, the fraction that we need to subtract from 3/4 to get 2/3 is 1/12.

In the given diagram, the area of the sector is 61.25 square units

The arc length is 17.5 units

From the question, we are to calculate the area and arc length for the given sector.

If  we need to determine the area of a sector when the angle is given in radians, we will use the formula

Area of sector = (1/2) × r²θ

Where θ is the angle subtended at the center (in radians)

and r is the radius of the circle

From the given information,

r = 7

θ = 2.5

Thus,

Area of the sector = (1/2) × 7² × 2.5

Area of the sector = 61.25 square units

To determine the arc length, we will use the fromula

L = rθ

where L is the arc length

r is the radius of the circle

and θ is the angle measured in radians

Thus,

The arc length = 7 × 2.5

The arc length = 17.5 units

Answer:

Theoretical probability is a mathematical concept that represents the likelihood of an event occurring based on mathematical reasoning or calculation. It is calculated by dividing the number of favorable outcomes by the total number of possible outcomes in a given situation. For example, the theoretical probability of flipping a coin and getting heads is 1/2, because there is one favorable outcome (heads) out of two possible outcomes (heads or tails).

Experimental probability, on the other hand, is based on actual observations or experiments. It is calculated by conducting an experiment and counting the number of times an event occurs, then dividing that by the total number of trials. For example, if you flip a coin 100 times and get heads 55 times, the experimental probability of getting heads is 55/100 or 0.55.

The main difference between theoretical and experimental probability is that theoretical probability is based on mathematical calculations and reasoning, while experimental probability is based on actual observations and experiments. Theoretical probability is used to predict the likelihood of an event occurring, while experimental probability is used to estimate the likelihood of an event occurring based on observed data.

[tex]\left(4, \sqrt{13}\right)\;\textsf{and}\;\left(4, -\sqrt{13}\right)[/tex]

Step-by-step explanation:

Let the point on the curve be (x, y).

Use the distance formula to create an equation for the distance between (8, 0) and (x, y):

[tex]\implies d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]

[tex]\implies d=\sqrt{(x-8)^2+(y-0)^2}[/tex]

[tex]\implies d=\sqrt{(x-8)^2+y^2}[/tex]

Since x² - y² = 3, then y² = x² - 3.

Substitute this into the equation so that we have an equation for d in terms of x:

[tex]\implies d=\sqrt{(x-8)^2+x^2-3}[/tex]

Simplify:

[tex]\implies d=\sqrt{x^2-16x+64+x^2-3}[/tex]

[tex]\implies d=\sqrt{2x^2-16x+61}[/tex]

[tex]\implies d^2=2x^2-16x+61[/tex]

Minimize d by taking the derivative of d with respect to x::

[tex]\implies \dfrac{\text{d}}{\text{d}x}d^2=\dfrac{\text{d}}{\text{d}x}2x^2-\dfrac{\text{d}}{\text{d}x}16x+\dfrac{\text{d}}{\text{d}x}61[/tex]

[tex]\implies 2d\dfrac{\text{d}d}{\text{d}x}=4x-16[/tex]

[tex]\implies \dfrac{\text{d}d}{\text{d}x}=\dfrac{4x-16}{2d}[/tex]

[tex]\implies \dfrac{\text{d}d}{\text{d}x}=\dfrac{2x-8}{d}[/tex]

Set it to zero and solve for x:

[tex]\implies \dfrac{2x-8}{d}=0[/tex]

[tex]\implies 2x-8=0[/tex]

[tex]\implies 2x=8[/tex]

[tex]\implies x=4[/tex]

Therefore, the value of x that minimizes d is x = 4.

To find the y-coordinate(s), substitute x = 4 into the equation of the curve:

[tex]\begin{aligned}x=4 \implies (4)^2-y^2&=3\\16-y^2&=3\\y^2&=13\\y&=\pm \sqrt{13}\end{aligned}[/tex]

Therefore, the points on the curve x² - y² = 3 that are closest to the point (8, 0) are (4, √13) and (4, -√13).

Answer:

  -3/8 -69/(64x -56)

Step-by-step explanation:

You want the result of dividing (3x+6) by (-8x+7).

The steps in polynomial long division are substantially identical to the steps in numerical long division. The quotient term at any step is the ratio of the leading terms of the dividend and divisor. The new dividend is found by subtracting the product of the quotient and divisor from the dividend.

The first quotient term is (3x)/(-8x) = -3/8.

The remainder is the difference of the dividend and the product of the quotient and divisor:

  remainder = (3x +6) -(-3/8)(-8x +7) = 3x +6 -3x +21/8 = 8 5/8 = 69/8

The degree of this remainder is less than the degree of the divisor, so the division is finished.

We often like to have the polynomials have positive leading coefficients, so we will express the result that way:

  [tex]\dfrac{3x+6}{-8x+7}=\boxed{-\dfrac{3}{8}+\dfrac{\left(\dfrac{69}{8}\right)}{-8x+7}}\\\\\\=-\dfrac{3}{8}-\dfrac{\left(\dfrac{69}{8}\right)}{8x-7}=\boxed{-\dfrac{3}{8}-\dfrac{69}{64x-56}}[/tex]

The answer is B, 6/10. This is because the probability of pulling out a number that is divisible by 2 or 3 is 6 out of 10.

Outcome is the result of an action, event or process. It is the final product or effect of an activity and is often used to measure the success or failure of something.

This can be calculated by dividing the number of events that meet the criteria by the total number of possible outcomes.

In this case, there are 6 numbers that are divisible by 2 or 3 (2,3,4,6,8,9) and 10 pieces of paper with numbers 1 to 10, so 6/10.

To express this probability in percentages, the answer would be 60%. This means that there is a 60% chance of pulling out a number that is divisible by 2 or 3.

This type of probability calculation is used in many situations, such as determining the probability of an event occurring in a game or determining the likelihood of something happening in a given sample size. It is important to understand how to calculate these probabilities in order to make informed decisions.

Numerοus οther names and abbreviatiοns are alsο used fοr them, such as sine, variance, guidance, and οthers. (csc).

Here,

The fοllοwing trigοnοmetric identities are applicable:

sin(alpha + beta) = sin(alpha)cοs(beta) + cοs(alpha)sin(beta)

tan(alpha + beta) = (tan(alpha) + tan(beta))/(1 - tan(alpha)tan(beta))

We can use the Pythagοrean identity tο get cοs(alpha) since we knοw frοm the given data that sin(alpha) = 15/17:

=> cοs(alpha) = √(1 - sin²(alpha)) = √(1 - (15/17)²) = 8/17

We may use the Pythagοrean identity tο get cοs(beta) because we alsο knοw that sin(beta) = 12/13.

=> 56/221

=> tan(alpha + beta) = (tan(alpha) + tan(beta))/(1 - tan(alpha)tan(beta))

=> (15/8 + (-12/5))/(1 - (15/8)(-12/5))

The ocean current has a bearing of S 50.3º E and a speed of 60 miles per hour.

Speed is defined as the rate of change of distance with time. It has the dimension of distance by time. Thus, the SI unit of speed is given as the combination of the basic unit of distance and the basic unit of Time. Thus, the SI unit of speed is metre per second.

We know that the SS Bigfoot is traveling on a course of N 35º W, which means its bearing with respect to due north is 35º westward. To find the ocean current's bearing and speed, we need to use the information about the captain's position after half an hour of travel.

In half an hour, the SS Bigfoot has traveled at a speed of 49 miles per hour * 0.5 hours = 24.5 miles. From the diagram, we can see that the captain's position after half an hour of travel forms a right triangle with the bay and the point where the captain started.

Let's call the point where the captain started Point A, the captain's position after half an hour Point B, and the bay Point C. We know that the distance between Point A and Point B is 24.5 miles, and the distance between Point B and Point C is 30 miles. We can use the Pythagorean theorem to find the distance between Point A and Point C:

a² + b² = c²

24.5² + 30² = c²

c ≈ 39.0 miles

So the captain is 39.0 miles from the bay after half an hour of travel.

Now we can use trigonometry to find the bearing of the ocean current. Let's call the bearing of the ocean current x. We know that:

tan x = opposite/adjacent

tan x = 30/24.5

x ≈ 50.3º

So the ocean current has a bearing of S 50.3º E.

To find the speed of the ocean current, we can use the formula:

speed = distance/time

The distance traveled by the captain is the same as the distance of the ocean current, which is 30 miles. The time it took for the captain to travel this distance is half an hour. Therefore:

speed = 30/0.5 = 60 miles per hour

So the ocean current has a speed of 60 miles per hour.

Putting it all together, the ocean current has a bearing of S 50.3º E and a speed of 60 miles per hour.
