Answer:

13

Step-by-step explanation:

As per the BODMAS, 8+6=14

14/2=7

20-7=13

Answer: The answer is 13!

Step-by-step explanation:

The first thing that you have to do is use PEMDAS, and do the things in parentheses first. This is 8+6. This equals 14. Divide 14 by 2 to get 7. The final thing to do is 20-7, and this is 13. Thus the answer is 13.

Step-by-step explanation:

Look at the figure attached which illustrates the Percentages at different regions which we will use it to solve the required questions.

8 - The Percentage of Data below the Upper Quartile = 25% + 25% + 25% = 75%

9 - The Percentage of Data located between the Lower Quartile and the Median = 25%

10 - The Percentage of the Data above the Median = 25% + 25% = 50%

Answer:

163/40

Step-by-step explanation:

multiply 4x40

then add 3

= 163

then put it over 40

163/40

Answer:

To simplify 4 3/40, we need to convert the mixed number to an improper fraction and then simplify:

4 3/40 = (4 × 40 + 3) / 40 (convert to improper fraction)

= 163 / 40

Now, we can simplify this fraction by finding the greatest common factor (GCF) of the numerator and denominator, which is 1:

163 / 40 = (163 ÷ 1) / (40 ÷ 1)

= 163 / 40

Therefore, 4 3/40 in simplest form is 163/40.

Reason:

The numerator is [tex](2.1)^5[/tex]

Raising that to the third power gives

[tex]((2.1)^5)^3 = (2.1)^{5*3} = (2.1)^{15}[/tex]

We multiply the exponents. The general rule is

[tex](a^b)^c = a^{b*c}[/tex]

Use that same rule to cube the denominator.

[tex]((0.9)^4)^3 = (0.9)^{4*3} = (0.9)^{12}[/tex]

Therefore,

[tex]\left(\frac{(2.1)^5}{(0.9)^4}\right)^3=\frac{((2.1)^5)^3}{((0.9)^4)^3}\\\\=\frac{(2.1)^{5*3}}{(0.9)^{4*3}}\\\\=\frac{(2.1)^{15}}{(0.9)^{12}}\\\\[/tex]

In short

Answer:

[tex]\text{A}=19.6 \ \text{m}^2[/tex]

Explanation:

We are given a circular circus tent

diameter = 5m

we know that

[tex]\text{radius}=\dfrac{\text{diameter}}{2}[/tex]

[tex]\text{radius}=\dfrac{\text{5}}{2}[/tex]

[tex]\text{radius}=2.5[/tex]

so, [tex]\text{r}=2.5[/tex]

now, we can use area formula

[tex]\text{A}=3.14(\text{r})^2[/tex]

now, we can plug values

[tex]\text{A}=3.14(\text{2.5})^2[/tex]

[tex]\text{A}=19.625[/tex]

so,

[tex]\text{A}=19.6 \ \text{m}^2[/tex]

Answer:

Step-by-step explanation:

The approximate area of the floor of the circus tent is 19.625 square metres.

The area to be found is that of a circle. The data given in the question is

the diameter of the circle. To calculate the area of the circle, we need to first find the radius. The radius is half of the diameter. By calculation, d/2, we get 5/2= 2.5m. The formula for finding the area of the circle is πR². By substituting the values, we get A(Area) = 3.14 (given) * 2.5 * 2.5 square metres. The area comes out to be 19.625 square metres.

Answer: 48 small shirts

108 medium shirts

84 Large shirts

Step-by-step explanation:

20% of 240 = 48

45% pf 240 = 108

45 + 20 = 65, 100 - 65 = 35

35% of 240 = 84

And 48 + 108 + 84 = 240

74% percent of the students read less than six magazines

percentage, a relative value indicating hundredth parts of any quantity.

A histogram shows the number of magazines read last month by the students in a class

The total number of students are 2+15+3

Number of students=23

Number of students read less than six magazines is 17

Now let us find 17 is what percent of 23

x/100×23=17

23x=1700

Divide both sides by 23

x=1700/23

x=73.9

x=74%

Hence, 74% percent of the students read less than six magazines

Answer:

Answer is B)

Step-by-step explanation:

Josiah's mistake is (b) He did not multiply the numerator and denominator by the correct number to equal 1,500

The proportion is given as:

Multiply both sides by 1500

Evaluate the expression on the right-hand side

Multiply 10 by 1500 on the left-hand side

Divide 15000 by 20 on the left-hand side

Rewrite the equation as:

From the question, we can see that the products are not well carried out.

Hence, Josiah's mistake is (b)

He got the  rock songs part right. He did not multiply the numerator and denominator by the correct number until 1500.

What is fraction and example?

A fraction is numerical value that is a part of a whole. It is evaluated by dividing a whole into number of parts

Types of Fractions Proper fraction,Improper fraction,Mixed fraction,Like fractions,Unlike fractions,Equivalent fractions.

The statements that are true about Josiah's solution are:

He correctly found the proportion of rock songs  by setting  the ratio (number of rock songs in the sample) / (total number of songs in the sample) = (number of rock songs in the MP3 player) / (total number of songs in the sample). sample MP3 player) and solving for x:

Start Fraction 10 over 20 EndFraction = Start Fraction x over 1500 End Fraction.

Initial fraction 10 times 30 over 20 times 30 final fraction = initial fraction x over 1500 final fraction.

300 = x.

 He didn't hit the average of the  rock songs right because the average of 4 and 6 is 5, not 300.  

He did not multiply the numerator and denominator by the correct number to 1500 because he should have multiplied both by 75 instead of 30 to get:

Initial fraction 10 times 75 over 20 times 75 final fraction = initial fraction x over 1500 final fraction. He did not have to divide 10 by 2 when he determined the ratio, because the ratio is already in its simplest form. So the real arguments are:

He got the  rock songs part right. He did not multiply the numerator and denominator by the correct number until 1500. He did not have to divide 10 by 2 to determine the ratio.
