Answer: 22+(-3)
Step-by-step explanation:
Answer:
45
Step-by-step explanation:
We are assuming that the pole's shadow and buildings shadow are proportional so our ratio is
x/36=1.9/1.52
cross multiply
1.52x=68.4
simplify
x=45
Answer:
The correct answer is
Z⁶Y³/Z⁶Y⁴ = 1/Y
Step-by-step explanation:
<u>Points to remember</u>
1). xᵃ * xᵇ = xᵃ⁺ᵇ
2). xᵃ/xᵇ = xᵃ⁻ᵇ
3). x° = 1
4). x⁻ᵃ = 1/xᵃ
The given expression is Z⁶Y³/Z⁶Y⁴
<u>To find the simplification of expression</u>
Z⁶Y³/Z⁶Y⁴ = Z⁶⁻⁶ * Y³⁻⁴
= Z° * Y⁻¹ = 1 * 1/Y = 1/Y
Therefore the value of given expression Z⁶Y³/Z⁶Y⁴ is 1/Y
The answer is -12
because you just have to simplyfy it and plug in the values
<h2>HOW TO: SOLVE AN APPLICATION</h2>
Step 1. Identify what you are asked to find and choose a variable to represent it.
Step 2. Write a sentence that gives the information to find it.
Step 3. Translate the sentence into an equation.
Step 4. Solve the equation using good algebra techniques.
Step 5. Check the answer in the problem and make sure it makes sense.
Step 6. Write a complete sentence that answers the question.
Remember that whatever the application, once we write the sentence with the given information (Step 2), we can translate it to a percent equation and then solve it.
Do you pay a tax when you shop in your city or state? In many parts of the United States, sales tax is added to the purchase price of an item. See Figure 6.7. The sales tax is determined by computing a percent of the purchase price.
To find the sales tax multiply the purchase price by the sales tax rate. Remember to convert the sales tax rate from a percent to a decimal number. Once the sales tax is calculated, it is added to the purchase price. The result is the total cost—this is what the customer pays.
