Answer:

97.5/100

Step-by-step explanation:

To write 97.5% as a fraction in simplest form, we first convert the percentage to a decimal by dividing it by 100: 97.5% / 100 = 0.975. We can then express this decimal as a fraction by using the fact that any number can be represented as a fraction with the number as the numerator and a power of 10 as the denominator: 0.975 = 0.975/1. Finally, we simplify the fraction by dividing the numerator and denominator by the greatest common factor, which in this case is 1: 0.975/1 = 97.5/100. Therefore, 97.5% can be written as the fraction 97.5/100 in simplest form.

Answer:

39/40

Step-by-step explanation:

97.5/100

   Step 1: Write down the percent divided by 100;

   Step 2: If the percent is not a whole number, then multiply both top and bottom by 10 until you get an integer at the numerator.

   Step 3: Simplify (or reduce) the fraction if it is not in the simplest form.

(a) The depreciation for the first year is $99,732.40.  (b) If the Machine was sold at the end of the fifth year, the gain or loss is $498,662

We know that in accounting, depreciation is the loss on a fixed asset over the accounting period that benefited from it.

Using straight line method of depreciation,

Depreciation = [tex]\frac{Cost os asset-Residual value}{Estimated number of years}[/tex]

Applying the figures we have

Depreciation = [tex]\frac{637362-138700}{5}[/tex]

The value of x for the triangle is equal to 17.32.

Pythagorean theorem states that in the right angle triangle the hypotenuse square is equal to the square of the sum of the other two sides. According to this statement, the areas of the squares on the other two sides add up to the size of the square whose side is the hypotenuse.

Calculate the perpendicular side for both triangles by using the Pythagorean theorem.

H² = P² + B²

Here, H is the hypotenuse, P is perpendicular and B is the base.

For the first triangle, the perpendicular is calculated as,

P² = x² - 10²......................................................1

For the second triangle, the perpendicular will be,

P² = ( 30² - x² ) - 20²  .......................................2

Equate the equation 1 and 2 and solve,

x² - 10² = ( 30² - x² ) - 20²

x² - 100 = 900 - x² - 400

2x² = 900 - 400 + 100

The total distance ran during these days, written as a mixed number, is (38 + 3/4)mi

We know that the student ran a distance of (3 + 1/2) miles each day for 5 days, so the amount that the student ran in these 5 days is given by the product:

5*(3 + 1/2) mi = (15 + 5/2) mi

Now, on the next 5 days, the student ran a distance of (4 + 1/4) miles, so the total distance that the student ran in these days is:

5*(4 + 1/4) mi = (20 + 5/4)mi

Now to get the total distance that the student ran on the 10 days we need to add the two distances above, we will get:

(15 + 5/2) mi +  (20 + 5/4)mi

So we have a sum of mixed numbers, we can rewrite this as:

(15 + 5/2) mi +  (20 + 5/4)mi = (15 + 20)mi + (5/2 + 5/4)mi

(15 + 20)mi + (5/2 + 5/4)mi = 35mi + (10/4 + 5/4) mi

35mi + (10/4 + 5/4) mi = 35mi + 15/4mi

35mi + 15/4mi = 35mi + 12/4 mi + 3/4 mi

35mi + 12/4 mi + 3/4 mi  = (38 + 3/4)mi

Answer:

a)  A' = (2, 4)

b)  A'' = (1, -2)

Step-by-step explanation:

When reflecting a shape in a vertical line, each vertex of the shape will be the same distance from the vertical line but in the opposite direction.  

Therefore, the x-values change but the y-values remain the same.

To reflect point A in x = -1, determine the number of horizontal units the point is from x = -1.  Count the same number of units on the other side of the vertical line (remembering that the y-value remains unchanged).

The x-value of point A is x = -4.  This is 3 units to the left of x = -1.

Therefore, the x-value of point A' is 3 units to the right of x = -1.

The y-value of point A is y = 4, so the y-value of point A' is also y = 4.

Therefore, the coordinates of the point A' are:

To translate point A' by the given vector, translate the point:

The value of f(5) When a polynomial f(x) is divided by x -5 is 4

Polynomials are algebraic expressions that consist of variables and coefficients. Variables are also sometimes called indeterminates. We can perform arithmetic operations such as addition, subtraction, multiplication, and also positive integer exponents for polynomial expressions but not division by variable.

If f(x) has a remainder of 4 when divided by x - 5

Then it means that if f(x -5) = f(0)

x -5 = 0

x = 5

so if you substitute 5 into f(x) which is f(5) it will give 4

so therefore f(5) = 4

The distance for Tucker to walk is 1 mile, only then both the donors would have the same amount. This was found using linear equations.

What are linear equations?

A linear equation is one in which the variable's maximum power is consistently 1. A one-degree equation is another name for it. A linear equation with one variable has the formula Ax + B = 0, which is its standard form. x is a variable, A is a coefficient, and B is constant in this situation. A linear equation with two variables has the formula Ax + By = C as its standard form. Here, the variables are x and y, the coefficients are A and B, and the constant is C.

Since it's given that Tucker's mother will give flat $5. So let that be the RHS of the equation. Now his grandmother will give him $5 for every mile he walks.

Let that be 5x.

Now the equation would be: 5x=5

Which results in x=1.

Answer:

2.51 x 10^5

Step-by-step explanation:

Scientific notation gives you a number between 1 and 10 multiplied by a power of ten. In this case, you'll want to use the significant digits, 251, and divide or multiply by a power of ten to get a number between 1 and 10.

251,000 can become 2.51 (which is between 1 and 10) multiplied by 10 to a certain exponent. All you need to do is calculate the exponent.

2.51 x 10^(?) = 251,000

For each power of 10, the decimal moves a space. Since you want the decimal to move 5 spaces, you'll want to multiply 2.51 by 10^5.

2.51 x 10 = 25.1

2.51 x 10^2 = 251

2.51 x 10^3 = 2510

2.51 x 10^4 = 25,100

2.51 x 10^5 = 251,000

The appropriate estimate for the diameter of the speck of dust is 2 × 10⁻⁵ inches. So the answer is option A, 2 × 10⁻⁵ in.

In scientific notation, numbers are written with the base 10 much like in decimal notation. Scientific notation is the term used when a number is expressed as the product of two numbers.

Where the first number is more than or equal to one but less than ten and the second number is the power of ten expressed in exponential form.

Step - 1 Move the decimal point up to the first number that is equal to 1 but less than 10.

Step - 2 Count the number of places that the point moved.

Step - 3 Now Write the resultant number as a product with a power of 10.            

Here we have

Diameter of a speck of duct = 0.00002 inches

Convert the given decimal into a scientific notation

As we learn above

Move the decimal point up to a whole number toward the right

=> 0.00002 = 2. = 2

Count the number of zeros or places moved

=> n = 5

Now write the number as a power of 10, Now write the above whole number part as the product of 10

=> 2 × 10⁻⁵     [ ∵ The power is moved right we need to use negative ]    

Therefore,

The appropriate estimate for the diameter of the speck of dust is 2 × 10⁻⁵ inches. So the answer is option A, 2 × 10⁻⁵ in.
