[tex]Hello[/tex] [tex]There![/tex]

  We are asked to find the value of n in the equation [tex]\bold{\displaystyle\frac{n}{8} =\frac{11}{5}}[/tex].

It's not hard, I promise! I am going to take you through a few steps, and we'll find the answer.

Are you ready? Then let's begin... :)

[tex]Procedure:[/tex]

First, we need to multiply both sides by the denominator of n/8, which is 8:

[tex]n/8*8=(11/5)*8[/tex]

On the left side of the equal sign, the 8's cancel, leaving us with n.

[tex]n=(11/5)*8[/tex]

We can write 8 as 8/1. Now we multiply 11 times 8 and 5 times 1:

[tex]n=(11*8/5*1)[/tex]

Which is the same as

[tex]n=88/5[/tex]

▲ this answer is already in it's simplest form, we can't simplify it further

I suppose it asks for how many have been sold.

So we have $50 for design fees.. then $5.25/shirt..

The total is $55.25 per shirt.

We divide $1362.50 to $55.25 and we get 24 shirts with $36 set loose.

Answer:

the answer is 7/27 cause you find the total number of tiles and total number of black tile then put it in the ratio of :

total no of black tiles/ total tiles

Answer:

The answer is 7/27

Step-by-step explanation:

For this you will be using What you want over the total of what you have. Sum all the things which gives you: 27 in total.

You want only the black ones, so add 3+4 and you get 7

What you want is the black (7) over the total amount you have (27)

so your answer is 7/27

C.) supplementary angles, complementary angles

Step-by-step explanation:

Look at the picture below.

A supplementary angle(s) has a total sum of 180°

A complimentary angle(s) has a total sum of 90°

Other angles like congruent, only refer to an angle that is exactly the same.

Therefore, C would be the correct answer.

Answer:

20%

Step-by-step explanation:

Method 1

Percentage of people who preferred red:

= 13%

Percentage of people who named a rainbow color:

= 13 % + 4% + 5% + 15% + 16% + 12%

= 65%

Percentage of people who preferred red from those who named a rainbow color:

= (13% ÷ 65%) × 100

= 20%

Method 2

Number of people who preferred red:

= 13% of 500

= 13% × 500

= 0.13 × 500

= 65

Percentage of people who named a rainbow color:

= 13 % + 4% + 5% + 15% + 16% + 12%

= 65%

Number of people who named a rainbow color:

= 65% of 500

= 65% × 500

= 0.65 × 500

= 325

Percentage of people who preferred red from those who named a rainbow color:

= (number who preferred red ÷ number named rainbow color) × 100

= (65 ÷ 325) × 100

= 20%

Pls Brainliest!

Answer:

20%

Step-by-step explanation:

The rainbow colors add up to 13 + 4 + 5 + 15 + 16 + 12 = 65 percent of the pie chart. So, 65% ∙ 500 = 325 people in the survey named a rainbow color. Of these, 13% ∙ 500 = 65 named red.

Therefore, if we consider only the 325 people who named a rainbow color, the percentage of those people who preferred red is

65/325 = 1/5 = 20%

(You may notice that the answer would still be 20% even if the total number of people in the survey were some number other than 500. This is because 13% is 20% of 65%, no matter what these are percentages of!)

Step-by-step explanation: First we multiply 3 1/1x3 1/4.

Then we simplify 93/(11x4).

Hope this helped!

The product of the fractions 3/11 and 3 1/4 is 39/44.

Here, we have,

To find the product of the fractions 3/11 and 3 1/4,

we need to convert the mixed number 3 1/4 to an improper fraction and then multiply the two fractions.

Step 1: Convert the mixed number to an improper fraction.

3 1/4 = (4 * 3 + 1) / 4 = 13/4

Step 2: Multiply the two fractions.

(3/11) * (13/4)

= (3 * 13) / (11 * 4)

= 39 / 44

So, the product of the fractions 3/11 and 3 1/4 is 39/44.

Answer:

180

Step-by-step explanation:

If supplies cost 54$ and thats 30% of the total cost, that means you would divide 54 by 3 and that would be 18. Then you would times 18 by 10 to get your final answer: 180$. The reason you would times 18 by 10 is because 18 is 10% percent of 100% and 10 times 10 is 100.

If you multiply 1.25(50) is 62.5

and 62.5 is larger than 60

so,

:• No; they weigh 62.5 ounces

Answer: D

Step-by-step explanation:

Facts

each car ways 1.25 ounces

he has 50 cars

his container can hold 60 ounces

The question: Will the container hold all the cars without going over 60 ounces?

Step 1: Find the total number of ounces for all 50 cars

1.25 x 50= 62.5

Step 2: Compare

62.5 > 60

Because 62.5 is greater than 60, all of the cars CANNOT fit.

The amount of pies in mixed numbers is 5*1/2   and  in the improper fraction is 11/2 and in decimal is 5.5 and in percentage is 5.5%

Given: Susan buys 5 and a half pies from the market.

To find the value of the pies in the following ways:

The mixed fraction is represented as a whole number and also as a fraction. It is the mixture of a whole number and a fraction. The simple way to find out the mixed fraction is, first multiply the value in the denominator by the value of the whole number in the mixed fraction. Later add the obtained number. Here is the problem the mixed fraction can be written as 5*1/2.

The improper fraction is identified when the numerator is greater than the denominator. From the given question the value of pies in the improper fraction is given by 11/2. Here 11 is greater than 2.

Next, the decimal number is represented by a whole number that is separated from the decimal point of the fractional part. In question 5 and a half is represented as 5.5, where 5 is a whole number with a decimal point and the fractional part is 0.5.

The value of the percent is obtained by dividing the total value and multiplying it by 100. So from the question, we get 5*1/2*100 is equal to 250 or 5.5%.

Answer:

Step-by-step explanation:

You can use process of elimination of this question. All we need to know is that the flat line is y = -2. No answer choice has this, so the correct option is B.

Answer:

a) 156.25 cm^2  b) 221.67 cm^2  c) 65.42 cm^2

Step-by-step explanation:

a)

We know that the formula for the area of a quadrilateral is Length x Height (A = LH).

Since the length and height of a square is the same, L = 12.5cm and H = 12.5cm.

So we incorporate our formula for the area of a square into this situation:

A = 12.5 x 12.5

A = 156.25 cm^2

b)

We know that the formula for the area of a circle is Pi x radius squared (A = πr^2).

Since we know that the diameter of the circle is 16.8cm, we will use this to find the radius.

Radius can be found by halving the diameter (r = d/2).

So we incorporate our formula for radius into this situation:

r = 16.8/2

r = 8.4cm

Now that we have our radius, we can find the area of our circle.

So we incorporate our formula for the area of a circle into this situation:

A = π(8.4)^2

A = 221.6707776 = 221.67 cm^2

c)

We can see from the diagram that the shaded portion come mainly from the circle.  So to find the area of the shaded part, we can simply subtract the area of the square, from the area of the circle (A of circle - A of square = Area of shaded part).

So we incorporate our formula for the area of the shaded part into this situation:

A = 221.67 cm^2 - 156.25 cm^2

A = 65.42 cm^2

Answer:

87.92 in^3

Step-by-step explanation:

Formula for finding the volume of a cylinder:

V=Bh

B= area of the base

h= height

Diameter=4 radius=2 The radius is half of the diameter

The base of a cylinder is a circle, so you would find the area of the circle and multiply it by the height of the cylinder.

V= (3.14*2^2)7

V= (3.14*4)7

V= 12.56(7)

V= 87.92 in^3

Answer:

The answer to this question should be b. 87.92 in^3 because the formula to find the volume of a cylinder is V=TTr^2h. and remember that the radius is half of the diameter so back to the question.

We multiplied 3.14 times 4 because remember that the radius is half of the diameter and we get 2 but remember the exponent so we need to multiplied to the second power 2 times 2 and we get 4 so when we multiplied 3.14 times 4 we get 12.56 and when we multiplied 12.56 times the height which is 7 we get 87.92 so check the choices and see if there is an answer and yes there is so b which is 87.92in^3 is hopefully the correct answer.
