Answer:

<h2>12.95 or in fraction form 259/20</h2>

Step-by-step explanation:

Do you want to know how to write the decimal number 12.95 as a fraction?

Here we will show you step-by-step how to convert 12.95 so you can write it as a fraction.

You can take any number, such as 12.95, and write a 1 as the denominator to make it a fraction and keep the same value, like this:

12.95 / 1

To get rid of the decimal point in the numerator, we count the numbers after the decimal in 12.95, and multiply the numerator and denominator by 10 if it is 1 number, 100 if it is 2 numbers, 1000 if it is 3 numbers, and so on.

Therefore, in this case we multiply the numerator and denominator by 100 to get the following fraction:

1295 / 100

Then, we need to divide the numerator and denominator by the greatest common divisor (GCD) to simplify the fraction.

The GCD of 1295 and 100 is 5. When we divide the numerator and denominator by 5, we get the following:

259 / 20

Therefore, 12.95 as a fraction is as follows:

259 / 20

Rod and Reel, Inc. manufactures and sells fishing rods. The company uses the equation P = 25r – 12,500 to estimate its profit P

stiks02 [169]

P=25r-12500
p=125000 and r=?

125000=25r-12500
+12500 +12500
25r= 137500
r=137500/25
r= 5,500

Therefore the answer is B) 5,500

A student has a 30% chance of receiving chocolate ice cream for dessert at lunch. A statistics class designs a simulation to app

Nadusha1986 [10]

The count of the sections the class should label as "Chocolate Ice Cream" is 3.

<h3>How to calculate the probability of an event?</h3>

Suppose that there are finite elementary events in the sample space of the considered experiment, and all are equally likely.

Then, suppose we want to find the probability of an event E.

Then, its probability is given as

$P(E) = \dfrac{\text{Number of favorable cases}}{\text{Number of total cases}} = \dfrac{n(E)}{n(S)}$

where favorable cases are those elementary events who belong to E, and total cases are the size of the sample space.

For the considered case, it is given that:

Probability of an student getting Chocolate Ice Cream for dessert at lunch = 30% = 0.3

The count of the sections the class should label as "Chocolate Ice Cream" should be such that spinner getting "Chocolate Ice Cream" as option should have the probability as 0.3

Let the count of the sections the class should label as "Chocolate Ice Cream" be $x$

Then, as there are in total 10 sections in the spinner, and all sections are assumingly equally probable, thus, if the event E is:

E = event of getting "Chocolate Ice Cream" in the spinner ,

then as n(E) = $x$ (as there are $x$ sections with label "Chocolate Ice Cream")

and n(S) = total count of sections (size of sample space) = 10

Thus, we get probability of event E as:

$P(E) = \dfrac{n(E)}{n(S)} = \dfrac{x}{10}$

This needs to be equal to 0.3, thus,

$0.3 = \dfrac{x}{10}\\x = 3$

Thus, the count of the sections the class should label as "Chocolate Ice Cream" is 3.

A ceramic tile is in the shape of a triangle. The angle measurements of this triangle are 30 degrees, 60 degrees, and 90 degrees

adell [148]

Ratio of 30-60-90 triangles in terms of side lengths is 1- $\sqrt{3} 
$ -2

So, the side across the 30-degree angle is 6.25.
Thus, the side across the 90-degree angle (hypotenuse) is 12.5.

Tina has 1/2 of a pan of cornbread left from a dinner party. She eats 1/2 of the leftover part the next night. How much of the w

likoan [24]

Answer:

Tina ate 3/4 of the whole pan of cornbread.

Step-by-step explanation:

Let the amount of cornbread in the initial pan be <em>x.</em>

<em />

After the dinner party, Tina has 1/2 of x left; That is 1/2x

If she eats 1/2 of the leftover, that will be 1/2 of 1/2x that is eaten. This will be 1/4x that is eaten.

To find the potion of the whole pan that Tina ate, we will add the potion she ate during the party to the portion of the leftover she ate the next night.

That will be 1/2x + 1/4x =3/4x

Therefore, Tina ate 3/4 of the whole pan of cornbread.
