Answer:

8) 27.75

10) See down below. May be 1.83 OR 123.75, depending on what your problem says

Step-by-step explanation:

Problem 8)

Let's first take apart [tex]2^{3}[/tex], which will be 8. Now, let's plug that back into the equation real quick:

12 + (8 ÷ [tex]\frac{2}{3}[/tex]) + 3.75

Since dividing a fraction can also be equal to multiplying the reciprocal of that same fraction, ÷ [tex]\frac{2}{3}[/tex] can be re-written as: * [tex]\frac{3}{2}[/tex]

Let's put that into the equation now and solve:

12 + (8 * [tex]\frac{3}{2}[/tex]) + 3.75

= 12 + 12 + 3.75

= 27.75

Problem 10) (I'm unsure if the sign after 80 is ÷ or +, but I'll do equations for both)

(If the sign after 80 is ÷, check these steps on how to solve):

Same methods as problem 8. Let's first break down [tex]4^{2}[/tex], which will be 16. Then, let's set the ÷ [tex]\frac{2}{5}[/tex] to * [tex]\frac{5}{2}[/tex] and solve:

80 ÷ (16 * [tex]\frac{5}{2}[/tex]) + 3.75

= 80 ÷ (40) + 3.75

= [tex]\frac{80}{40+3.75}[/tex]

= 1.82857

(If the sign after 80 is +, check these steps):

80 + (16 * [tex]\frac{5}{2}[/tex]) + 3.75

= 123.75

If the price of gas increases by 5% again next week, will the price be 10% higher than it was

originally? Explain your reasoning.

Answers

If the price of gas increases by 5% again next week, then the price be approx 10% higher than it was originally because again shows that their is  two times increment of 5%.

Let the price of gas is x.

The price of gas is increased by 5% in a week. So after increment the price of gas = x + x × 5%

After increment the price of gas = x + 5x/100

After increment the price of gas = (100x + 5x)/100

After increment the price of gas = 105x/100

After increment the price of gas = 1.05x

The gas price again increase by 5%.

Now the price of gas after again increment = 105x/100 × 105%

The price of gas after again increment = 105x/100 × 105/100

The price of gas after again increment = 11025x/10000

The price of gas after again increment = 1.1025x

Now we find the total increment in two weeks

Percent Increment = (1.1025x - x)/x × 100

Percent Increment = 0.1025x/x × 100

Percent Increment = 0.1025 × 100

Percent Increment = 10.25%

Then we can say that approx 10% the cost of oil increased then originally.

coach mac finds a new practice court for the basketball team. if the width of the rectangular lot is 16 feet less than the length, and the perimeter is 160 feet, what are the dimensions of the new practice court?

perimeter of rectangle = 2W + 2L

first complete these equations: 160 = ?W + ? L ; W = L - ?

Answers

The dimensions of the new practice court is 45.5 feet by 29.5 feet.

The equations should be completed as 160 = 2W + 2L; W = L - 16

How to calculate the perimeter of a rectangle?

Mathematically, the perimeter of a rectangle can be calculated by using this mathematical expression;

P = 2(L + W) or P = 2L + 2W

Where:

P represents the perimeter of a rectangle.L represents the length of a rectangle.W represents the width of a rectangle.

Since the width of the rectangular lot is 16 feet less than the length, we have:

W = L - 16

Substituting the given parameters into the perimeter formula, we have;

160 = 2L + 2W

160 = 2(L - 16) + 2L

160 = 2L - 32 + 2L

160 = 4L - 32

4L = 182

L = 45.5 feet.

For the width, we have:

W = L - 16

W = 45.5 - 16

W = 29.5 feet.

what are the dimensions of a rectangular tract of land when it’s perimeter is 44 kilometers and it’s area is 120 square kilometers

Answers

Answer:

The dimensions of the rectangular tract of land with a perimeter of 44 kilometers and an area of 120 square kilometers are:

Length = 10 kilometers

Width = 12 kilometers

Explanation: To find the dimensions of a rectangular tract of land when its perimeter and area are known, you can use the formulas:

Perimeter = 2(length + width)

Area = length * width

We know that:

Perimeter = 44 kilometers

Area = 120 square kilometers

So, we can use these values to set up the following equation:

44 = 2(length + width)

And we can solve for length and width.

44 = 2(length + width)

22 = length + width

And now we know that the sum of the length and width of the rectangular tract is 22 kilometers.

Now we have to use the area formula:

Area = length * width

120 = length * width

We can use the value we have for the sum of the length and width to find either the length or the width of the rectangular tract.

For example, we can use the equation:

length = 22 - width

And substitute it into the area equation:

120 = (22 - width) * width

And then we can solve for width:

120 = 22 * width - width^2

width^2 - 22 * width + 120 = 0

We can use the quadratic formula to solve for width.

width = (22 +/- sqrt(22^2 - 4 * 1 * 120))/ 2

So,

width = (22 +/- sqrt(484 - 480))/ 2

width = (22 +/- sqrt(4))/ 2

width = (22 +/- 2)/ 2

width = (24)/ 2

width = 12

So, the width of the rectangular tract is 12 kilometers.

And we can use the equation:

length = 22 - width

to find the length

length = 22 - 12 = 10

So, the dimensions of the rectangular tract of land with a perimeter of 44 kilometers and an area of 120 square kilometers are:

Length = 10 kilometers

Width = 12 kilometers

a passenger jet took 3 hours to fly 1800 miles in the direction of the jet stream. The return trip against the jet stream took 4 hours. What was the jets speed in still air and the jet streams speed?

Answers

The speed of the jet in still air is 525miles per hour and the speed of the jet stream is 75miles per hour

What is speed ?

speed is defined as the rate of change of distance with time. It is measured in meter per second and it is a scalar quantity. It has other units like miles per hour, kilometers per hour e.t.c

The speed of the jet with jet stream = displacement /time = 1800/3 = 600 miles/hour

The speed of the jet against = distance /time = 1800 / 4 = 450 miles per hour

The speed of the jet in still air will be the average speed of the jet to and fro. = (600+450)/2

= 1050/2

= 525 miles per hour

Therefore the speed of the jet in still air = 525 miles per hour

Also, the the jet stream speed = 525- 450 = 75 miles per hour.

15 foot ladder leaning agaisnt a building touches the wall 12 feet above the ground how far from the building is the bottom of the ladder

Answers

The bottom of the ladder is 9 feet from the wall.

Using the Pythagorean Theorem, we can calculate the distance from the wall. The Pythagorean Theorem states that for a right triangle, the sum of the squares of the sides is equal to the square of the hypotenuse. In this case, the hypotenuse is 15 feet and the side adjacent to the wall is 12 feet.

The formula for the Pythagorean Theorem is a^2 + b^2 = c^2.

We can solve for the distance from the wall (a). a^2 = c^2 - b^2, so a^2 = 15^2 - 12^2, which equals a^2 = 225 - 144, so a^2 = 81. Taking the square root of both sides, a = 9 feet.

Therefore, the bottom of the ladder is 9 feet from the wall.

AdditionMultiplicationSubtractionDivision

What is a math operation?

An operation is a function in mathematics that transforms zero or more input values into a clearly defined output value. The operation's arity is determined by the number of operands.

Addition (+) is the most important of the four operations because it is the foundation of all arithmetic. It is used in everyday life for basic calculations such as adding up a grocery bill or calculating the total cost of a purchase with tax. It is also used in more advanced mathematical concepts such as algebra and calculus.

Multiplication (x) is the second most important operation because it is used to find the total number of items in a group or the total area of a shape. It is also used in more advanced mathematical concepts such as solving equations and finding derivatives.

Subtraction (-) is the third most important operation because it is used to find the difference between two numbers. It is also used in more advanced mathematical concepts such as algebra and calculus.

Division (÷) is the least important of the four operations because it is a reverse operation of multiplication, which is more important and more frequently used. It is used to find the number of times one number is contained within another or the size of a group when the total size and number of groups is known.

All four math operations are important and useful in different ways, but the order of importance is based on how frequently they are used and how foundational they are to other mathematical concepts.

What are the coordinates of the point on the directed line segment from (-9, 9) to (7, -7) that partitions the segment into a ratio of 3 to 5?

Answers

The coordinates of the point that partitions the segment is given as :  (-3, 21)

How to solve for the segment

To find the coordinates of the point on the directed line segment from (-9, 9) to (7, -7) that partitions the segment into a ratio of 3 to 5, we can use the concept of vector addition.

First, we can represent the directed line segment as a vector, with the initial point (-9, 9) being the tail, and the terminal point (7, -7) being the head. The vector representing the directed line segment is:

V = <7 - (-9), -7 - 9> = <16, -16>

To partition the segment into a ratio of 3 to 5, we can represent the partition point as a scalar multiple of the vector V:

P = (-9, 9) + (3/8)V = (-9, 9) + (3/8)(16, -16)

The scalar multiple 3/8 is used to get the partition point, it's calculated by dividing the desired ratio (3) by the sum of the ratio (3+5)

Then, we can find the x and y coordinates of the point P by applying the scalar multiple to the components of the vector:

P(x, y) = (-9, 9) + (3/8)(16, -16) = (-9, 9) + (3/8)(16, -16) = (-9 + 316/8, 9 - 3-16/8) = (-9 + 6, 9 + 12) = (-3, 21)

So the coordinates of the point on the directed line segment that partitions the segment into a ratio of 3 to 5 are (-3, 21).

Answers

The probability that there exists people who share the same birthday is 0.995.

Considering that all the 365 days are equally likely to be the birthday of a person and all the events that a person has birthday on 'y' are independent of others.

Under the said assumptions, let's say that there are n number of people in the room. If we number the people from 1 to n, then the total number of possibilities of birthdays are (365)^n.

Therefore, the possible combinations that all birthdays are different:

365 * 364 * 363 * .... * (365- n+1)

Thus, the probability that all birthdays are different is:

[tex]\frac{365* 364 * 363* .... (365- n+1)}{365^n}[/tex]

To get the probability of at least two people sharing the same birthday is,

[tex]1- \frac{365* 364 * 363* .... (365- n+1)}{365^n}[/tex]

Answers

The ratio of servings to cones is 47:4.

In mathematics, a ratio is a way of comparing two or more values. It is usually represented as a fraction, with the values being separated by a colon (:). For example, if you have 7 apples and 4 oranges, the ratio of apples to oranges would be 7:4. This can also be written as 7/4 or 1.75. Ratios can also be written as a decimal or a percentage. Ratios can be used to compare quantities, sizes, or measurements in different units.

If the ratio of servings to cups is 7:47:47:4, that means for every 7 servings, there are 47 cups.

Since the servings came in either a cup or a cone, but not both, the ratio of servings to cones is the remaining portion of servings that are not accounted for in the ratio of servings to cups.

So, it's 7 servings + 47 cups = 47 servings + 4 cups.

Simply put, probability measures how probable something is to occur. We can discuss the probabilities of various outcomes, or how likely they are, whenever we are unsure of how an event will turn out. Statistics is the study of events subject to probability. The likelihood that something will happen is known as probability. The number of possible outcomes is divided by the total number of possible outcomes to determine probability.

24 = 8h

To get h alone we will divide both sides of the equation by 8

24/8 = h

24/8 = 3

Making H = 3

What is the constant of proportionality? What does it represent?

Answers

Answer:

In Explanation

Step-by-step explanation:

The constant of proportionality is a value that relates two variables that have a proportionate relationship. It is often represented by the letter "k".

For example, if two variables x and y are directly proportional, their relationship can be represented by an equation of the form y = kx, where k is the constant of proportionality. In this equation, the value of k represents the ratio of y to x and it is constant, meaning that it does not change as the values of x or y change.

In physics, the constant of proportionality also appears in many mathematical models of natural phenomena, such as Hooke's law (F = km) which relates the force applied on an object (F) to its displacement (x) with a spring constant (k), and Ohm's law (V = IR) which relates the voltage (V) across a resistor to the current (I) flowing through it with a resistance constant (R).

The constant of proportionality can have different units of measure depending on the context and is used to make quantitative predictions about the relationship between the variables. In some cases, it can be used to determine the behaviour of a system or physical process.

Scientists deduce that most of Earths iron and nickel sunk to its core at this time in Earths history. Convection occurs in the outer core. Cool, dense matter sinks while warm, less dense matter rises. The flow of this liquid iron creates electric currents, which produce our magnetic fields. Periodically, the flow of fluid changes which results in a reversal of our magnetic field.
