4. If 4 bananas weigh 4 4/5 kilograms , how

Mathematics
1 answer:
quester [9]2 years ago
8 0

Answer:

It's the same process, change 4 4/5 to an improper fraction = 24/5 then set up a proportion

4 bananas/(24/5) kg = 3 bananas/x kg take cross products

4x = 3 (24/5) = 72/5  divide by 4 (this is the same as multiplying by 1/4)

x = 72/20, change this to a mixed number = 3 12/20 = 3 3/5 kg

What is 8x to the power 3 over 6x to the power 5
bulgar [2K]

In this question, you're simplifying the "fraction".

<em>Simplify:</em>

8x² / 6x^5

<em>First, simplify the 8 and the 6 by dividing by 2</em>

4x² / 3x^5

<em>Now simplify the exponents:</em>

The exponents is equivalent to: x² - x^5

x² - x^5 = -x²

Since it's a negative, it would stay in the bottom of the fraction, or the denominator.

4 / 3x²

Answer:

4 / 3x²

Given the pay rate and hours worked, determine the gross earnings, Federal taxes (assuming 18% of gross earnings), state taxes (
ella [17]

Answer:

Let us assume that the pay rate per hour = x

no. of hours worked = n

Gross earnings = x*n

Federal taxes = 18% of gross earnings

= 0.18(x*n)

State taxes = 4% of gross earnings

= 0.04(x*n)

Social security deduction = 7.05% of gross earnings

= 0.0705(x*n)

Total deductions = Federal taxes + State taxes +SSD

= 0.18(x*n) + 0.04(x*n) + 0.0705(x*n)

= 0.2905(x*n)

Net pay = Gross earnings - Total Deduction

Net pay = x*n - 0.2905(x*n)

Net pay = 0.7095(x*n)

Which of the following is the product of the rational expression shown below
wolverine [178]

Option C: \frac{x^{2}-9}{x^{2}-4} is the product of the rational expression.

Explanation:

The given rational expression is \frac{x+3}{x+2} \cdot \frac{x-3}{x-2}

We need to determine the product of the rational expression.

<u>Product of the rational expression:</u>

Let us multiply the rational expression to determine the product of the rational expression.

Thus, we have;

\frac{(x+3)(x-3)}{(x+2)(x-2)}

Let us use the identity (a+b)(a-b)=a^2-b^2 in the above expression.

Thus, we get;

\frac{x^{2} -3^2}{x^{2} -2^2}

Simplifying the terms, we get;

\frac{x^{2}-9}{x^{2}-4}

Thus, the product of the rational expression is \frac{x^{2}-9}{x^{2}-4}

Hence, Option C is the correct answer.
