If the cost of 3/4 tons of wood chips is $21 then the cost per ton of wood chips is $28.

To find the cost per ton of wood chips, we need to first determine the total cost of 1 ton of wood chips. We know that the cost of 3/4 tons of wood chips is $21, so we can set up a proportion:

3/4 tons / 21 = 1 ton / x

where x is the unknown cost per ton.

To solve for x, we can cross-multiply and simplify:

3/4 tons × x = 21 × 1 ton

3/4 x = 21

x = 21 / (3/4)

x = 28

Therefore, the cost per ton of wood chips is $28.

Finding the cost per ton is a common problem encountered in many industries, particularly those that deal with bulk materials such as wood chips, sand, gravel, or other aggregates. To calculate the cost per ton, it is important to know the total cost of the material and the total weight (or volume) of the material. It's important to note that this method works for any bulk material, as long as the weight (or volume) and cost are known. This information can be used to make informed decisions about purchasing and budgeting for materials, as well as comparing costs across different suppliers.

This is a linear equation with a slope of 2 and a y-intercept of -2. There is exactly one solution for y for every value of x.

In mathematics, an equation is a statement that two expressions are equal. It usually contains one or more variables, which are unknown quantities that can take on different values. Equations are used to represent relationships between quantities, and they can be used to solve problems by finding the values of the variables that make the equation true.

An equation typically consists of two sides, separated by an equal sign. Each side can contain numbers, variables, and mathematical operations such as addition, subtraction, multiplication, division, exponents, and roots. For example, the equation:

2x + 3 = 7

contains the variable x, as well as constants 2, 3, and 7, and mathematical operations of addition and multiplication.

Equations can be solved by applying algebraic techniques to isolate the variable on one side of the equation. For example, to solve the above equation for x, we can first subtract 3 from both sides to get:

2x = 4

Then, we can divide both sides by 2 to get:

x = 2

This is the solution to the equation, which means that x must be equal to 2 in order to make the equation true.

Equations are used in many areas of mathematics, including algebra, calculus, geometry, and trigonometry. They are also used in physics, engineering, and other sciences to model physical phenomena and solve problems related to them.

To solve for y, we need to isolate y on one side of the equation.

y + 2 = 2x

Subtract 2 from both sides:

y + 2 - 2 = 2x - 2

Simplify:

y = 2x - 2

Therefore, the solution for y is y = 2x - 2.

This is a linear equation with a slope of 2 and a y-intercept of -2. There is exactly one solution for y for every value of x.

Answer: The probability that a point chosen at random is in the blue region is approximately 0.96.

Step-by-step explanation:

To find the probability that a point chosen at random is in the blue region, we need to compare the area of the blue region to the area of the entire circle.

The area of the circle is given by the formula A = πr^2, where r is the radius of the circle. Since we know the area of the circle is 314 square centimeters, we can solve for the radius:

A = πr^2

314 cm^2 = πr^2

r^2 = 100

r = 10 cm

The circle has a radius of 10 centimeters.

The square inside the circle has a side length of 2 centimeters, so its area is 2^2 = 4 square centimeters.

To find the area of the blue region, we need to subtract the area of the square from the area of the circle. Since the square is inscribed in the circle, the diameter of the circle is equal to the diagonal of the square. Using the Pythagorean theorem, we can find the diameter of the circle:

d^2 = 2s^2

d^2 = 2(2 cm)^2

d^2 = 8

d = sqrt(8) cm

The diameter of the circle is sqrt(8) centimeters.

The area of the circle is A = πr^2 = π(10 cm)^2 = 100π square centimeters.

The area of the blue region is the area of the circle minus the area of the square:

blue region = A - 4 cm^2

blue region = 100π - 4 square centimeters

The probability that a point chosen at random is in the blue region is therefore:

P(blue) = (blue region) / (total area)

P(blue) = (100π - 4) / (100π)

P(blue) ≈ 0.96

Therefore, the probability that a point chosen at random is in the blue region is approximately 0.96.

Jose invests money in an account paying a simple interest of 9% per year, he should multiply his current balance by 9% to find his total balance.

Simple Interest is a simple way for computing interest on a loan or principle amount. The notion of simple interest is used in many sectors, including banking, finance, and vehicles. The monthly interest is deducted first, followed by the principal amount, when you make a loan payment.

We have rate of interest as 9%

So, SI = PNR/100

SI = P x 1 x 9/100

SI = P x 9%.

Therefore, current balance should be multiplied by 9% .

Simple Interest (S.I.) is a way of determining the amount of interest for a given principle amount. You put that money to use for the reason you borrowed it in the first place. The money is then returned after you receive your following month's pocket money from your parents. This is how borrowing and lending operate in the real world.

Answer:3

Step-by-step explanation:

Anil borrowed the sum of money $12,300 on rate of 10% per annum, for a period of 5 years.

We can use the simple interest formula to solve this problem:

Simple Interest = (Principal x Rate x Time) / 100

Where,

Principal = 12,300

Rate = 10% per annum

Simple Interest = 18,450 - 12,300 = 6,150

Substituting the given values in the formula, we get:

6,150 = (12,300 x 10 x Time) / 100

Simplifying the equation, we get:

Time = (6,150 x 100) / (12,300 x 10)

Time = 5 years

Therefore, Anil borrowed the money for a period of 5 years. Simple interest is a type of interest calculation where the interest is calculated only on the principal amount borrowed or invested. It is calculated as a percentage of the principal amount, multiplied by the time period of the loan or investment. Simple interest does not take into account any interest earned on interest, unlike compound interest. It is a straightforward method used to determine the total amount to be repaid on a loan or the interest earned on an investment. Simple interest is commonly used in personal loans, small business loans, and short-term investments.

To find the time at which the object is again at x=0, we need to solve the equation vx(t) = 0, which gives us:

αt - βt^3 = 0

t(α - βt^2) = 0

The solutions to this equation are t = 0 (which corresponds to the initial position) and t = ±√(α/β). Since we're looking for a nonzero time, we can discard the t = 0 solution and take t = √(α/β):

t = √(α/β) = √(7.2 m/s^2 / 4.8 m/s^4) = √(1.5 s^2) = 1.22 s
