The hypotenuse of a right triangle measures 10 inches and the side opposite to <0 one of the non right angles is 5 inches long

The measure of <0 is
30
45
60
90
?

Answers

Final answer:

The measure of angle <0 in the right triangle is approximately 30 degrees.

Explanation:

To find the measure of angle <0 in the right triangle, we can use trigonometry. The side opposite to angle <0 is given as 5 inches. The hypotenuse is given as 10 inches. We can use the sine ratio to find the angle:

sin(<0) = opposite/hypotenuse

substituting the given values:

sin(<0) = 5/10 = 0.5

Now, to find the measure of angle <0, we can use the inverse sine function:

<0 = arcsin(0.5)

Using a calculator, we find that the measure of angle <0 is approximately 30 degrees.

Suppose you go shopping for a new futon bed for your apartment/home. The model you really like happens to be on sale for $1100. It's original price is $1200. What percent of the original price will you save if you purchase it? Write your answer to the nearest tenth of a percent, but in decimal form.

Answers

If a model of a bed is on sale for $1100 out of $1200, you determine the percentage off with 1100/1200, which simplifies to 11/12. 11/12 is 91.7%. We then subtract that from 100%, so we get 100-91.7, leading us to a percentage saved of 8.3%.

Final answer:

To have an inverse function, a function must be bijective, meaning it is both one-to-one (injective) and onto (surjective). An example is shown with the function f(x) = x^2 which is not injective, hence doesn't have an inverse function.

Explanation:

In mathematics, to have an inverse function, the original function, represented as f, must be both injective (one-to-one) and surjective (onto). This dual property is called being bijective. This means every element of the function's domain maps to one distinct element in the function's range (injective) and that every element in the range has a pre-image in the domain (surjective).

For example, consider the function f(x) = x^2. This function is not injective, as both f(-2) and f(2) give the same output, hence it does not have a true inverse function across all real numbers.

a boat salesperson earns a 2.5% commission on the sale of each boat Find the commision earned on a boat that sells for 18,500

Answers

100% = 1.0
2.5% = 0.025

So now we know the decimal that corresponds to 2.5%, so all we have to do is multiply the price of the boat by this value in order to find the commission earned:

18 500 x 0.025 = $462.50

Whenever you need to find the percentage OF a number (often money), you just convert that percentage to a decimal (just move the decimal to the left twice so 40% becomes 0.40, 10.5% becomes 0.105, 2% becomes 0.02, etc) and MULTIPLY that decimal by the amount/number you need to find the percentage of.

For example, find the 20% commission of a $10,000 car sale

ALGEBRA 2- Which equation has the solutions x = 1 ± √5 ?

A. x2 + 2x + 4 = 0
B. x2 – 2x + 4 = 0
C. x2 + 2x – 4 = 0
D. x2 – 2x – 4 = 0

Answers

A. But you can also read a book and not rely on this

D. x^2 - 2x - 4 = 0

You can solve this problem 2 different ways.
1. Plug in a value of x = 1 ± √5 into each of the possible equations and see if the result is 0.
or
2. Use the Quadratic formula to solve each of the equations and see which comes up with the correct answer.

For this case, I'll use the 2nd option.
A. x^2 + 2x + 4 = 0
a = 1, b = 2, c = 4
Upon attempting this, you'll quickly discover that you're going to try to get the square root of -12. Since there's no imaginary terms in the desired root, this equation can't be it.

B. x^2 – 2x + 4 = 0
Same issue here, trying to get the square root of a negative number. So this one doesn't work either.

C. x^2 + 2x – 4 = 0
Getting closer. Have (-2 ± sqrt(20)) / 2 = -1 ± √5
Still not it, but closer. At least not trying to get the square root of a negative number.

D. x^2 – 2x – 4 = 0
Since the other 3 are wrong, this must be right. But let's do the math anyway.
a = 1, b = -2, c = -4
The quadratic formula gets (2 ± sqrt(20)) / 2 = (2 ± 2√5)/2 = 1 ± √5
And it works out. So this is the answer.

C) 22,341 > 21,730
D) 22,341 < 24,687

Answers

B. 21,730 is not greater than 22,341.

Final answer:

The false statement among the given options is B) 21,730 > 22,341. The greater than, less than symbols should be accurately used to compare two numbers. The other given statements are true.

Explanation:

The false statement in the given options is B) 21,730 > 22,341. This statement is saying that 21,730 is greater than 22,341, which is false. In mathematics, '<' symbol represents 'less than' and '>' represents 'greater than'. So, the statement B) is false because 21,730 is not greater than 22,341, but less.
Comparing the following two statements A) 21,730 < 22,341 and C) 22,341 > 21,730, we can see they are actually the same statement, restated in a different manner. Both statements are saying that 21,730 is less than 22,341 which is true.
The statement D) 22,341 < 24,687 is also true because 22,341 is less than 24,687.

Final answer:

Numbers can be written in exponential form with a base of 10. For example, 100 is written as 10^2, 100,000 as 10^5, and 10,000 as 10^4.

Explanation:

To write numbers in exponential form, you need to understand the concept of exponential notation which is a way to express a number as a base raised to a power. In each of the given cases, the base is 10.

For 100, there are two zeros following the 1. This means that 100 can be written as 10 to the power of 2, or 10^2.

Similarly, for 100,000, there are five zeros following the 1. This would be written as 10 to the power 5, or 10^5.

Lastly, 10,000, has four zeros following the 1. This would be written as 10 to the power of 4, or 10^4.

Assume that lines that appear to be parallel are parallel. Find the value of x and the measure of angle y

Answers

What information have we been given here? From the diagram, we can see that (9x+1)° and (14x-34)° degrees are supplementary, meaning:

(9x+1)+(14x-34)=180

There, we have an equation we can fairly easily solve for x. What about y?

If we take a look at the line y° occupies, we can see that it shares a straight angle with our (14x-34)° term and - as implied by the right angle on the bottom line - a 90° angle.

All three of these should add up to 180°, so we have:

(14x-34) + y + 90 = 180

Another think to note is that, upon inspection, (14x-34)° and y° are complementary - they add up to 90° - and subtracting the 90 from both sides of our equation confirms that fact:

(14x-34) + y = 90

If you've solved for x prior to this, solving for y should be pretty straightforward.

Answer:

The answer would be (14x-34) + y = 90.

The larger of two numbers is one more than four times the smaller number. if the sum of the numbers is 106, find the numbers.

Answers

Call the numbers x and y. According to the first sentence, x = 4y + 1. According to the second sentence, x + y = 106. You can combine these two equations to find the values of these variables:

x + y = 106
4y + 1 + y = 106
5y = 105
y = 21

We have y, so now we can solve for x using either original equation:

x + y = 106
x + 21 = 106
x = 85

Final answer:

To solve the problem, create two equations based on the information given, then solve these equations step-by-step. After calculation, the two numbers are 21 and 85.

Explanation:

Given the problem, we can translate and create two equations which are:

The larger number is one more than four times the smaller number. We can express this as: L = 4S + 1 The sum of the numbers is 106. We can express this as: L + S = 106

Step 1: From the first equation, we know that L = 4S + 1. We can substitute this into the second equation in place of L, giving us 4S + 1 + S = 106.

Step 2: Add up, and we get 5S + 1 = 106. Subtract 1 from both sides and we get 5S = 105.

Step 3: Divide both sides by 5 to solve for S, we get S = 21.

Step 4: Substitute S = 21 into the equation L = 4S + 1, you can calculate and find L = 85.

Therefore, the two numbers are 21 and 85.
