Answer:

m∠R= 87°

Step-by-step explanation:

The angles in a polygon add up to (n-2)180

(5-2)180= 540°

You can set up an equation to add all the angles together equaling 540°.

Once you solve for x, plug that back into the formula for the angle of R(7x-11)

Are you looking to calculate whether 2/10 is greater than 11/20? One of the most common calculations you'll make in math is to compare fractions. In this really simple guide, we'll teach you how to compare and determine if 2/10 is bigger than 11/20 and walk you through the step-by-process of how the calculation is made.

As we always do in these tutorials, let's recap and remind ourselves that the number above the fraction line is called the numerator and the number below the fraction line is called the denominator.

Depending on the math problem you want to solve, there are two methods to calculate if 2/10 is larger than 11/20:

Convert the fractions to have the same denominator

Convert the fractions to a decimal number

Let's start with the first method: converting the fractions to the same denominator. First, we'll set up 2/10 and 11/20 side by side so they are easier to see:

Converting Denominator

2

10

&

11

20

Our denominators are 10 and 20. What we need to do is find the lowest common denominator of the two numbers. This is the smallest number that can be divided by both 10 and 20. In this case, the lowest common denominator is 20.

If we multiply the first denominator (10) by 2 we will get 20. If we multiply the second denominator (20) by 1 we will also get 20. We also need to multiply the numerators above the line by the same amounts so that the fraction values are correct:

2 x 2

10 x 2

11 x 1

20 x 1

This is what 2/10 and 11/20 looks like with the same denominator:

4

20

&

11

20

Now that these fractions have been converted to have the same denominator, we can clearly see by looking at the numerators that 4 is NOT greater than 11 which also means that 2/10 is NOT greater than 11/20.

Converting to Decimal

You can also compare these fractions by first converting them to decimal format. This is a lot faster than working out the lowest common denominator. All we do here is divide the numerator by the denominator for each fraction:

2/10 = 0.2

11/20 = 0.55

Now that these fractions have been converted to decimal format, we can compare the numbers to get our answer. 0.2 is NOT greater than 0.55 which also means that 2/10 is NOT greater than 11/20.

Hopefully this tutorial has helped you to understand how to compare fractions and you can use your new found skills to compare whether one fraction is greater than another or not!

Answer:

I. p = 7

II. 17 litres

Step-by-step explanation:

I. Determination of the value of p

Mean = 17.7

p =.?

Let the number of litre be L

Let the number of motorist be M

Mean = summation LM / summation M

Summation of LM = (16×11) + (17×10) + (18×p) + (19×4) + (20×8)

= 176 + 170 + 18p + 76 + 160

= 582 + 18p

summation M = 11 + 10 + P + 4 + 8

= 33 + p

Mean = summation LM / summation M

17.7 = 582 + 18p / 33 + p

Cross multiply

17.7(33 + p) = 582 + 18p

584.1 + 17.7p = 582 + 18p

Collect like terms

584.1 – 582 = 18p – 17.7p

2.1 = 0.3p

Divide both side by 0.3

p = 2.1 / 0.3

p = 7

II. Determination of the median number of litre.

Let the number of motorist be M (i.e the frequency)

summation M = 11 + 10 + P + 4 + 8

p = 7

summation M = 11 + 10 + 7 + 4 + 8

summation M = 40

The median is the middle term i.e

Median = (summation M / 2)ᵀʰ motorist

Median = (40 / 2)ᵀʰ motorist

Median = 20ᵀʰ motorist

Considering the table in the question above, the 20ᵀʰ motorist has 17 litres.

Therefore, the median number of litres is 17 litres.

A linear relationship is a connection that takes the shape of a straight line on a graph between two distinct variables - x and y. When displaying a linear connection using an equation, the value of y is derived from the value of x, indicating their relationship.

The rule is given in the question, as follows:

y is 3 less than x

For each value of x in the first column, the corresponding value of y in the second column can be calculated by subtracting 3 from x.

For example, if x is 10, then y is 3 less than x, which is 7 (10 - 3 = 7).

Similarly, if x is 8, then y is 5 (8 - 3 = 5), and if x is 6, then y is 3 (6 - 3 = 3).

The table for the given rule can be completed as follows:

X Y

A prediction based on the data is reliable, because the means of the samples are close together.

Step-by-step explanation:

Test approved

The most accurate statement is A. A prediction based on the data is reliable, because the means of the samples are close together.

Mean of a set of data is defined as the average of all the values. It gives the exact middle point of the data set.

Given three data sets.

All the samples have 10 data points.

Number of data points = 10

Mean of sample 1 = 9.1

Mean of sample 2 = 9.4

Mean of sample 3 = 8.9

We can see that the mean of the three samples is so close to each other.

So the data is reliable.

Hence the option is A.

Answer:

The artist can make six batches of orange paint and it remains one cup of yellow paint

Step-by-step explanation:

1. Let's review the information given to us to answer the question correctly:

Amount of red paint for one batch of orange paint = 1/3 of a cup

Amount of yellow paint for one batch of orange paint= 1/3 of a cup

Amount of red paint available = 2 cups

Amount of yellow paint available = 3 cups

2. How many batches of orange paint can she make?

2 cups of red paint = 6/3 = 6 batches of orange paint

3 cups of yellow paint = 9/3 = 6 batches and it remains one cup of yellow paint

The artist can make six batches of orange paint and it remains one cup of yellow paint

Answer:

Los conjuntos numéricos que se relacionan entre sí son:

Naturales, enteros y racionales.

Los números naturales son aquellos números que se pueden escribir como sumas de 1.

Los números enteros son todos los números naturales, y agregamos el número cero y los números negativos.

Los números racionales son aquellos números que se escriben como cociente de dos números enteros. Acá también podés notar que:

7 = 7/1

entonces todo número entero se puede escribir como el cociente de dos enteros, lo que implica que el conjunto de los números racionales también engloba al conjunto de los enteros.

Entonces si N es el conjunto de los números naturales, Z es el conjunto de los números enteros, y Q es el conjunto de los números racionales, tenemos que:

N ⊂ Z ⊂ Q.

Ahora por otro lado, el conjunto de los números irracionales es aquel que no se puede escribir como cociente de dos números enteros. Con esto ya podemos concluir que no existe ningún elemento compartido entre ninguno de los conjuntos anteriores y este conjunto, y esto se debe a la definición de número irracional, como no se puede construir como el cociente de números enteros, entonces no hay forma de relacionarlo con ninguno de los otros conjuntos.
