this is a conversion problem

First you must understand that 1 foot = 12inches

Given a ribbon that is 5 1/2 feet long

To convert to inches, you will simply multiply 5 1/2 by 12 as shown;

= 5 1/2 * 12

convert the mixed fraction to improper fraction

= 11/2 * 12

= 11 * 12/2

= 11 * 6

= 66 inches

Hence the ribbon is 66 inches long

From the statement of the question, we know that 1 ounce and 30ccs are equivalent, we represent that with the following equation:

[tex]1\text{ounce}=30\text{ccs.}[/tex]

Now, 2 ounces is double of 1 ounce, because 1 ounce is 30 ccs, 2 ounces must be 60ccs, the double of 30ccs.

a store advertises a 20% markdown on a dishwasher that normally sells for $952. what is the price on sale

Answers

The price on sale of the dishwasher is $201.6

How to determine the price on sale?

From the question, we have the following parameters that can be used in our computation:

Mardown = 20%

Selling price = $252

The price on sale of the dishwasher is calculated using the following equation

Price on sale = Selling price * (1 - Mardown)

Substitute the known values in the above equation, so, we have the following representation

Price on sale = 252 * (1 - 20%)

Evaluate

Price on sale = 201.6

We will use the law of sines and law of cosines shown below

Therefore, in our case, finding side c.,

[tex]\begin{gathered} a=28,b=13,C=49\degree \\ \Rightarrow c=\sqrt{784+169-2*28*13cos(49\degree)} \\ \Rightarrow c\approx21.8 \end{gathered}[/tex]

If pp is inversely proportional to the square of qq, and pp is 22 when qq is 8, determine pp when qq is equal to 4.

Answers

Given that p is inversely proportional to the square of q that implies:

[tex]p\propto\frac{1}{q^2}[/tex]

Remove the sign of proportionality and put a proportionality constant k such that:

[tex]p=\frac{k}{q^2}[/tex]

Given that when q is 8 then p is 22. So,

[tex]22=\frac{k}{8^2}\Rightarrow k=22\times64=1408[/tex]

Put k = 1408 and q = 4 in the equation to find the value of p:

[tex]p=\frac{1408}{4^2}=\frac{1408}{16}=88[/tex]

Thus, the answer is 88.

Answers

To find the factors of a number we must find all the numbers that divide 24, two numbers are always easy, 1 and the number itself! But how do we find the others? We start at 1 and divide the number (here it's 24) by all the possible numbers until we reach the number we are finding the factor, it the division is an integer number, then it's a factor!

Another thing may help us! if we divide a number, for example, 24 by 2, the result is 12. Then 2 is a factor of 24 but 12 is also a factor of 24! Then when we find one factor, in fact, we have 2 factors. Now let's apply it to our problem:

As we can see, just by 3 divisors we found all the factors of 24! They are 1, 2, 3, 4, 6, 8, 12, 24

lebron walked 4 1/2 miles to library in 2 1/4 hours. he walked the return trip at the same average rate , but a different route, taking my 2 1/2 hours. How many miles did lebron walk on the return trip?

Answers

Answer:

5 miles

Explanation:

First, we need to transform the mixed number into decimal numbers using as follows:

[tex]\begin{gathered} 4\frac{1}{2}=4+\frac{1}{2}=4+0.5=4.5\text{ miles} \\ 2\frac{1}{4}=2+\frac{1}{4}=2+0.25=2.25\text{ hours} \\ 2\frac{1}{2}=2+\frac{1}{2}=2+0.5=2.5\text{ hours} \end{gathered}[/tex]

Now, the average rate was the same, so the ratio of the miles to the hours is always the same. Therefore, we can write the following equation:

[tex]\frac{\text{Miles}}{\text{Hours}}=\frac{4.5\text{ Miles}}{2.25\text{ Hours}}=\frac{x}{2.5\text{ Hours}}[/tex]

Where x is the number of miles that Lebron walked on the return trip. So, solving for x, we get:

[tex]\begin{gathered} \frac{4.5}{2.25}=\frac{x}{2.5} \\ \frac{4.5}{2.25}\times2.5=\frac{x}{2.5}\times2.5 \\ 5=x \end{gathered}[/tex]

Therefore, Lebron walked 5 miles on the return trip.

Don’t know how to solve with the -1 before the x

Answers

ANSWER and EXPLANATION

We are given a function and its inverse function:

[tex]\begin{gathered} f(x)=\frac{1}{2}x \\ f^{-1}(x)=2x \end{gathered}[/tex]

To solve the problems, we have to substitute the values of x in the brackets into the appropriate function (or inverse function).

Therefore, we have that the value of the function for x = 2:

[tex]\begin{gathered} f(2)=\frac{1}{2}\cdot2 \\ f(2)=1 \end{gathered}[/tex]

For x = 1, we have that the value of the inverse function is:

[tex]\begin{gathered} f^{-1}(1)=2(1) \\ f^{-1}(1)=2 \end{gathered}[/tex]

For x = -2, we have that the value of the inverse function is:

[tex]\begin{gathered} f^{-1}(-2)=2\cdot-2 \\ f^{-1}(-2)=-4 \end{gathered}[/tex]

For x = -4, we have that the value of the function is:

[tex]\begin{gathered} f(-4)=\frac{1}{2}\cdot-4 \\ f(-4)=-2 \end{gathered}[/tex]

For the fifth option, substitute the value of the function at x = 2 into the inverse function.

That is:

[tex]\begin{gathered} f^{-1}(f(2))=f^{-1}(1)=2\cdot1 \\ f^{-1}(f(2))=2 \end{gathered}[/tex]

For the sixth option, substitute the value of the inverse function at x = -2 into the function.

That is:

[tex]\begin{gathered} f(f^{-1}(-2))=f(-4)=\frac{1}{2}\cdot-4 \\ f(f^{-1}(-2))=-2 \end{gathered}[/tex]

To find the general form of the function:

[tex]f^{-1}(f(x))=f(f^{-1}(x))[/tex]

either substitute the function for x in the inverse function or substitute the inverse function for x in the function.

Therefore:

[tex]\begin{gathered} f^{-1}(f(x))=2(\frac{1}{2}x)) \\ f^{-1}(f(x))=x \end{gathered}[/tex]

That is the answer.

The sum of three numbers is 154. The first number is 10 more than the second. The third number is 4 times the second. What are the numbers?First number:х5?Second number:000Third number

Answers

Let's call those numbers a, b and c.

Since their sum is 154, we have:

a + b + c = 154

Also, since the first number is 10 more than the second, we have:

a = b + 10

And, since the third number is 4 times the second number, we have:

c = 4b

Now, we can use the expressions of a and c in terms of b in the first equation:

a + b + c = 154

b + 10 + b + 4b = 154

6b + 10 = 154

6b = 154 - 10

6b = 144

b = 144/6

b = 24

Then, we can use the value of b to find a and c:

a = b + 10

a = 24 + 10

a = 34

c = 4b

c = 4 * 24

c = 96

Therefore,

• First number: ,34

,

• Second number: ,24

,

• Third number: ,96

Here, we want to get the length of the ladder

The kind of triangle we have is a right triangle for which obeys the Pythagoras' theorem

According to the theorem, the square of the hypotenuse equals the sum of the squares of the two other sides

The length of the ladder marked as h is the hypotenuse

Thus, we have it that;

[tex]\begin{gathered} h^2=9^2+7^2 \\ h^2\text{ = 81 + 49} \\ h^2\text{ = 130} \\ h\text{ = }\sqrt[]{130} \\ h\text{ = 11.40 meters} \end{gathered}[/tex]

Which relation represents a function sample A or sample B

Answers

Sample A is a function because we don't have 2 values of x that are the same

Sample B is not a function, because it fails the vertical line test (x = 4 and y =1 also x=4 and y = 10) (4, 1) and (4, 10)

Hence the correct option is ; sample A
