If the value of a commodity decreases at a monthly rate of 0.8%, by 9.6 percentage it decreases in a year.

It's the ratio of two integers stated as a fraction of a hundred parts. It is a metric for comparing two sets of data, and it is expressed as a percentage using the percent symbol.

It is given that, the value of a commodity decreases at a monthly rate of 0.8%,

We have to find by what percentage the rate decreases in a year.

If there are 12 months in a year, the rate decrease in a year obtained as,

=0.8 × 12

=9.6 %

Thus, if the value of a commodity decreases at a monthly rate of 0.8%, by 9.6 percentage it decreases in a year.

In a year, the value of commodity decreases by 9.6%, at the monthly rate of 8%.

Ratio basically compares quantities, that means it show value of one quantity with respect to other quantity.

If a and b are two values, their ratio will be a:b,

Given that,

Monthly decrease rate of change in commodity = 0.8 %,

To find the percentage decrease in year,

Use ratio property,

In 1 month, commodity decreases 0.8%

In 12 months commodity decreases = 12 x 0.8 = 9.6 %

Answer:

Step-by-step explanation:

10% of 20 is equal to 2. To calculate 10% of a number, we can multiply the number by 10% expressed as a decimal, which is 0.1. For example, 10% of 20 is equal to 20 * 0.1 = 2.

Alternatively, we can calculate 10% of a number by dividing the number by 100 and then multiplying the result by 10. For example, 10% of 20 is equal to (20 / 100) * 10 = 2.

The required solutions of percentages are below as :

100% of 60 kg = 60 kg, 20% of 60 kg = 12 kg, and 40% of 60 kg = 24 kg.

The percentage is defined as a ratio expressed as a fraction of 100.

The double number line shows that Henrik has a mass of 60kg.

According to the given question, the required solution would be as:

100% of 60 kg

⇒ (100/100) x 60

⇒ 1 x 60

⇒ 60

So, 100% of 60 kg = 60 kg

20% of 60 kg

20%  is expressed as 20/100 in fractional form

⇒ (20/100) x 60

20/100 is expressed as 0.20 in decimal form

⇒ 0.20 x 60

Apply the multiplication operation, and we get

⇒ 12

So, 20% of 60 kg = 12 kg

40% of 60 kg

⇒ (40/100) x 60

⇒ 0.40 x 60

⇒ 24

So, 40% of 60 kg = 24 kg.

Thus, the required solutions are 100% of 60 kg = 60 kg, 20% of 60 kg = 12 kg, and 40% of 60 kg = 24 kg.

The number of acres owned for which the average intake is 2200 calories per day is 2 acres obtained by the algebraic expression that relates the acres of land and the calories per day.

It is given that, the number of calories consumed daily by a person owing x acres of land is given by the algebraic expression,

C(x) = 270 ln(x+1) + 1900

The average intake of calories consumed per day is given by C(x) = 2200

Here x is the number of acres of land. Then, the required number of acres of land is

C(x) = 270 ln(x+1) + 1900

⇒ 2200 = 270 ln(x+1) + 1900

⇒ 270 ln(x+1) = 2200 - 1900

⇒ 270 ln(x+1) = 300

⇒ ln(x+1) = 300/270 = 10/9

Applying base 'e' on both sides, we get

⇒ (x+1) = [tex]e^\frac{10}{9}[/tex]

⇒ x+1 = 3.0377

⇒ x = 3.0377 - 1 = 2.0377

When rounding the final answer to the nearest tenths, we get x = 2 acres.

When rounding the final answer to the nearest thousand, we get x = 2.038 acres.

Thus, for an average intake of 2200 calories per day, the number of acres of land owned is approximately 2 acres.

What is a quadratic function?

A quadratic function is a polynomial function with one or more variables in which the highest exponent of the variable is two.

Solution:

Given :

a = 2 , vertex = (5, -18)

f(x) = a(x-h)² + K

f(x) = 2(x - 5)² - 18

f(x) = 2(x² -10x + 25) -18

f(x) = 2x² - 20x +50 - 18

f(x) = x² - 10x +16

∴ x² -10x + 16 = 0

x² - 8x - 2x + 16 = 0

x(x-8) -2(x-8) = 0

The quadratic function has 2 solutions which is x = 2 and x = 8.

A quadratic function is a polynomial function with one or more variables in which the highest exponent of the variable is two. A polynomial of degree two in one or more variables in mathematics is known as a quadratic polynomial. Any polynomial function that is defined by a quadratic polynomial is said to be quadratic.

The terms "quadratic polynomial" and "quadratic function" were almost interchangeable before the 20th century because it was difficult to tell a polynomial from its corresponding polynomial function. This is still true in many elementary courses where "quadratic" is frequently used to refer to both terms.

Solution:

Given :

     a = 2 , vertex = (5, -18)

f(x) = a(x-h)² + K

f(x) = 2(x - 5)² - 18

f(x) = 2(x² -10x + 25) -18

f(x) = 2x² - 20x +50 - 18

f(x) = x² - 10x +16

∴ x² -10x + 16 = 0

x² - 8x - 2x + 16 = 0

The values of x in the first, second, third and fourth triangles are 4 units, 70°, 76° and 80° respectively

To solve this problem, we need some angle geometry knowledge:

For the first triangle:

x = 4 (All sides in a rhombus are identical)

For the second triangle:

The missing side is also equal to x (base of isosceles triangles)

x + x + 40 = 180 (sum of angles in triangle)

2x+40 = 180

2x = 180-40

2x = 140

x = 70°

For the third triangle:

x = 76° (base of isosceles triangles are equal)

For the fourth triangle:

Check the image attached for labeling

m = 180-110 = 70° (angle on a straight line)

y = 70° (base of isosceles triangles are equal)

z = 180-70-70 = 40°

t = 90-40 = 50°

L = 50° (base of isosceles triangles are equal)
