What are fractions?

Every number of equal parts is represented by a fraction, which also represents a portion of a whole. A single object or a collection of objects might be whole. A fraction is a component or section taken from a whole, which can be any number, a certain amount, or an object. The fractional bar is a horizontal bar that divides the numerator and denominator of every fraction into these two halves. The number of parts into which the whole has been divided is shown by the denominator. How many sections of the fraction are displayed or chosen is shown in the numerator.

Given,

 The amount of rice the restaurant had when they opened = 13 lbs

The amount of rice that was cooked and served = 3 1/12lbs

We are asked to find the amount of rice left.

This can be found by subtracting the amount of rice served from the total amount of rice.

Note that the amount of rice served is in fractions.

So we use fraction subtraction to solve this.

Then,

amount of rice left = 13 - 3 1/12

3 1/12 is a mixed fraction.

We should convert it into an improper fraction.

3 1/12 = (3*12 + 1 ) /12 = 37/12

Now solving,

amount of rice left = 13 - 3 1/12 = 13 - 37/12

Taking LCM to make a common denominator.

LCM = 12

amount of rice left = 13 - 37/12 = (13*12 - 37)/12 = 119/12 = 9 11/12 lbs.

Therefore after finding the difference, we found that the amount of rice left after lunch, written in mixed fraction form, is 9 11/12 lbs.

Answer:

Step-by-step explanation:

If two bakers can make 30 loaves in 1 hour, then we can use proportionality to find how many hours it would take for 3, 5, 6, and 15 bakers to make 30 loaves.

Let h be the number of hours needed for a given number of bakers to make 30 loaves. Then we have:

2 bakers can make 30 loaves in 1 hour, so 1 baker can make 15 loaves in 1 hour.

Therefore:

3 bakers can make 45 loaves in h hours, so 45/3 = 15 loaves can be made in 1 hour. Thus, 3 bakers can make 30 loaves in 2 hours.

5 bakers can make 75 loaves in h hours, so 75/5 = 15 loaves can be made in 1 hour. Thus, 5 bakers can make 30 loaves in 2 hours.

6 bakers can make 90 loaves in h hours, so 90/6 = 15 loaves can be made in 1 hour. Thus, 6 bakers can make 30 loaves in 2 hours.

15 bakers can make 225 loaves in h hours, so 225/15 = 15 loaves can be made in 1 hour. Thus, 15 bakers can make 30 loaves in 2 hours.

Therefore, regardless of the number of bakers, it would take 2 hours to make 30 loaves of bread.

What is expression ?

An expression is a combination of numbers, symbols, and operators that represents a mathematical quantity or relationship. It can contain variables, constants, and mathematical operations such as addition, subtraction, multiplication, and division. Expressions can be simple or complex and can be evaluated or simplified to a single value or another expression. Examples of expressions include 2x + 3, 4y - 7, (x + 5) / 2, and √(x² + y²).

We can solve the equation as follows:

|7x+4|/8 = 3

|7x+4| = 3*8

|7x+4| = 24

Now we have two cases to consider:

Case 1: 7x+4 is positive

|7x+4| = 7x+4

7x+4 = 24

7x = 20

x = 20/7

Case 2: 7x+4 is negative

|7x+4| = -(7x+4)

-7x-4 = 24

-7x = 28

x = -4

Therefore, the solutions are x = -4 and x = 20/7. However, we need to check if they satisfy the original equation:

For x = -4:

|7(-4)+4|/8 = 3

|-24|/8 = 3

3 = 3 (satisfied)

For x = 20/7:

|7(20/7)+4|/8 = 3

|24+4|/8 = 3

28/8 = 3.5 ≠ 3 (not satisfied)

So the only solution that satisfies the original equation is x = -4.

Therefore, the answer of the given expression  is -4.

Answer:

Step-by-step explanation:

This problem involves a binomial distribution where the probability of success (passing on the first attempt) is 0.65, and the probability of failure (not passing on the first attempt) is 0.35. We want to find the probability that less than 3 out of 5 people pass on their first attempt.

We can use the binomial probability formula to calculate this:

P(X < 3) = P(X = 0) + P(X = 1) + P(X = 2)

Where X is the number of people who pass on their first attempt.

P(X = 0) = (5 choose 0) * 0.65^0 * 0.35^5 = 0.0024

P(X = 1) = (5 choose 1) * 0.65^1 * 0.35^4 = 0.0289

P(X = 2) = (5 choose 2) * 0.65^2 * 0.35^3 = 0.1323

So,

P(X < 3) = 0.0024 + 0.0289 + 0.1323 = 0.1636

Therefore, the probability that less than 3 out of 5 people pass their driver's tests on the first attempt is approximately 0.164, rounded to three decimal places.

Sure! Tidal energy is a type of renewable energy that is harnessed from the movement of ocean tides. There are different approaches to harnessing tidal energy, but the three options given in the question are:

I. Floating platform with turbines: This approach involves anchoring a floating platform in the tidal zone, where the rise and fall of the tides can be used to turn turbines and generate electricity. The turbines are connected to generators, which convert the mechanical energy of the turning turbines into electrical energy. This approach is commonly used in commercial tidal energy projects, such as the MeyGen tidal energy project in Scotland.

II. Floating ship with turning pendulum: This approach, also known as the "pendulor" or "pendulum" system, involves a floating ship or barge that is anchored in the tidal zone. The ship is designed to swing back and forth with the movement of the tides, and this movement is used to turn a pendulum, which in turn drives a generator. The idea behind this approach is that the ship's movement can be used to generate more energy than just the up-and-down motion of a floating platform with turbines. However, this approach is still in the experimental phase and has not yet been deployed on a commercial scale.

III. Having water spin turbines attached to fence: This approach involves installing turbines directly in the flow of tidal currents. The turbines are attached to a fence-like structure, which guides the flow of water and increases the speed of the current as it passes through the turbines. The spinning turbines generate electricity, which is then sent to a generator and converted into usable power. This approach is also known as "barrage" or "fence" technology, and it has been used in a few commercial tidal energy projects, such as the La Rance tidal power plant in France.

So, to answer the question, the correct answer is "I and III" since both involve using turbines to generate electricity from the movement of ocean tides.

Floating platform with turbines and Having water spin turbines attached to fence best  describes an approach used to harness tidal energy.

Energy is the capacity to do work

The approach used to harness tidal energy is described by option I and III.

I. Floating platform with turbines - This involves placing turbines on floating platforms that are anchored to the seabed.

As the tide comes in and out, the water flows through the turbines, generating electricity.

III. Having water spin turbines attached to fence - This involves building a fence-like structure across a tidal inlet.

As the tide comes in and out, the water flows through the fence and spins turbines, generating electricity.

Option II, floating ship with turning pendulum, does not describe an approach used to harness tidal energy.

Therefore, floating platform with turbines and having water spin turbines attached to fence best  describes an approach used to harness tidal energy.

The domain of a function is all the possible input values for which the function is defined.

Function is a block of code that performs a specific task. It is a reusable piece of code that can be called from other parts of the code, reducing the amount of code that needs to be written and making the code easier to read and maintain. Functions can take in parameters and return values, allowing for increased flexibility and reusability. Functions can also be used to break up large programs into smaller, more manageable pieces.

In this case, the reasonable domain for the function f(x) = 4x³-50x²+150x would be all real numbers. This is because the function is a polynomial, which is continuous, meaning that it is defined for all real numbers.

The input of the function is a width, and the output is a volume. Therefore, the domain of the function should include all reasonable widths that could produce a volume. This means that the domain should include all positive real numbers, as any negative value would produce a negative volume, which is not reasonable. Thus, the reasonable domain for the function f(x) = 4x³-50x²+150x is all positive real numbers.

The length of the rope swing is approximately 98.9 feet (rounded to the nearest tenth of a foot).

Algebraic expressions are used to represent mathematical relationships and formulas, and can be used to solve equations and manipulate equations in order to isolate variables or solve for unknown quantities. They are used extensively in algebra, calculus, and other branches of mathematics.

We are given that the time for one swing is given by the formula:

t = 2√(L/32.2)

where L is the length of the rope swing in feet, and 32.2 is the acceleration due to gravity in feet per second squared.

We are also given that one swing takes 3.5 seconds, so we can write:

3.5 = 2√(L/32.2)

Squaring both sides, we get:

12.25 = 4(L/32.2)

Multiplying both sides by 32.2/4, we get:

L = 32.2 × 12.25/4

L ≈ 98.9 feet

Therefore, the length of the rope swing is approximately 98.9 feet (rounded to the nearest tenth of a foot).
