give your own example of irrational number explain why the number you chose is irrational

Answers

Answer 1

√38 is irrational.

38 is an integer that is not the square of an integer, so its square root is not a rational number.

Answer 2

Answer: 157.34123598...

Step-by-step explanation: To determine if the decimal 157.34123598... is rational or irrational, notice that the decimal is non-terminating. However, this decimal is also non-repeating because there is no digit of group of digits that repeat.

When we have a decimal that is both non-terminating and non-repeating, it must be an irrational number.

A newspaper writer will write an article about the mean age of voters. She will estimate by selecting a sample of voters and calculating their mean age. Which method should the writer use to select the sample?randomly select 100 people who voted in the last election

select 100 people who voted in the last election and are more than 30 years old

select 100 people who voted for the most popular candidate in the last election

randomly select 100 people who read the newspaper

Answers

She should randomly select 100 people that voted in the last election.

This will avoid bias based on age, as we would see in the second choice. It will also ensure that the people who respond are actually voters, unlike the last choice; some people that read the newspaper may not be voters at all. Additionally, some candidates are more popular among certain age groups, so to avoid bias we should not select just voters that voted for the most popular candidate.

diane places 2 drawers with the same width and height on top of each other. what is the combined volume of the 2 drawers?

Answers

The combined volume of the two shapes is 3510 cubic inches.

To find the volume of each shape, use the formula: V = LWH.

The small shape is: 16 x 15 x 6 = 1350

The large shape is: 24 x 15 x 6 = 2160

Heya Freind
_________________________________________

We have the dimensions of 2nd drawer

length , L = 15 inch

Height , H = 6 inch

Breadth , B = 16 inch

so the volume of the Drawer = LBH

= 15 × 6 × 16 inch Cube

How many pieces 3/7 of a foot each can I make out of 7/2 feet of rope?

Answers

Final answer:

To find out how many 3/7 foot pieces can be made from 7/2 feet of rope, divide the total rope length by the length of one piece, resulting in 8 whole pieces with a small amount left over.

Explanation:

The question asks how many pieces of rope, each measuring 3/7 of a foot, can be made from a total length of 7/2 feet. To find the answer, you need to divide the total length of the rope (7/2 feet) by the length of each piece (3/7 foot), which is a division problem involving fractions:

(7/2) ÷ (3/7) = (7/2) × (7/3) = 49/6.

This means you can cut the rope into 49/6 pieces. Since you can't have a fraction of a physical piece of rope, the practical answer is that you can make 8 whole pieces of rope, each 3/7 of a foot long, with a little bit of rope left over.

Final answer:

You can make 8 full pieces of rope that are each 3/7 of a foot long from 7/2 feet of rope, with a small leftover piece.

Explanation:

The question asks how many pieces of rope measuring 3/7 of a foot each can be made from 7/2 feet of rope. To find this, we divide the total length of rope by the length of one piece:

Total length of rope: 7/2 feet
Piece length: 3/7 foot

We divide 7/2 by 3/7, which is the same as multiplying 7/2 by the reciprocal

of 3/7 (which is 7/3):

(7/2) * (7/3) = 49/6

This simplifies to 8 1/6, which means you can make 8 full pieces of rope that are each 3/7 of a foot long, with a small piece leftover.

The front panel and back panel are both 30*24 = 720 square inches. The left and right panels are 24*15 = 360 square inches

Add up the front, back, left and right panel areas and we get: 720+720+360+360 = 2160

The total gray area is 2160 square inches compared to the white lid which is 450 square inches. Subtract these two values: 2160-450 = 1710

Problem 4
You have to assume something or it is unsolvable.
We will assume that the triangle is divided into 2 smaller right triangles. They will be subject to a^2 + b^2 = c^2
a = 32/2 = 16
b = h
c = 20
20^2 = 16^2 + h^2
400 = 256 + h^2 Subtract 256
400 - 256 = h^2
144 = h^2
h = sqrt(144)
h = 12

Now we can find the area.
h = 12
base = b = 32

Area = 1/2 * b * h
Area = 1/2 * 32 * 12
Area = 192 square inches.

Problem 5
Same assumption. Same method.
a^2 + b^2 = c^2
c = 25
b = 7
h = ???
h^2 + 7^2 = 25^2
h^2 + 49 = 625
h^2 = 625 - 49
h^2 = 576
h = sqrt(576)
h = 24

Area = 1/2 Base * h
base = 2*7
base = b = 14

Area = 1/2 * 14 * 24
Area = 168 <<<< answer.

Can the sides of a triangle have lengths 6.2, 0.5, and 7.8?
yes or no

Answers

No, it's not possible for the sides of a triangle to have those lengths.

According to the triangle inequality theorem, the sum of any two sides of the triangle has to be bigger than the last side. Let's test this.

[tex]6.2+7.8\ \textgreater \ 0.5[/tex]

This inequality satisfies the triangle inequality theorem.

[tex]7.8+0.5\ \textgreater \ 6.2[/tex]

This also satisfies the theorem.

[tex]6.2+0.5 \textless \ 7.8[/tex]

Uh oh. This does not satisfy the triangle inequality theorem. Thus, it is not possible for a triangle to have these side lengths.

Melanie’s bedroom walls are 45% painted. The area of her walls totals 420 square feet. What is the number of square feet of Melanie’s walls that still need to be painted?

Answers

She still needs to paint 231 square feet.
You can get that by find out what 45% of 420 is (420 x 45 = y, divide it by 100), and subtracting it from 420 (420 - 189 = 231).
Or you can go right ahead and calculate what is the remaining percentage, which is 55%, so (420 x 55 = y, divide it by 100).

The percentage of Melanie's walls that still needed to be painted is 55 % and the number of walls is 231 feet²

What is Percentage?

A percentage is a number or ratio expressed as a fraction of 100. It is often denoted using the percent sign, %

The difference between an exact value and an approximation to it is the approximation error in a data value. Either an absolute error or a relative error might be used to describe this error.

Percentage change is the difference between the measured value and the true value , as a percentage of the true value

Percentage change =( (| Measured Value - True Value |) / True Value ) x 100

Given data ,

Let the percentage of Melanie's walls that still needed to be painted be A

Now , the equation will be

The total number of walls = 420 feet²

The percentage of Melanie's walls that are painted = 45 %

So , the remaining percentage A = 100 - percentage of Melanie's walls that are painted

The percentage of Melanie's walls that still needed to be painted A = 55 %

And , the number of walls that needed to be painted = percentage of Melanie's walls that still needed to be painted A x total number of walls

On simplifying , we get

The area of walls that needed to be painted = ( 55/100 ) x 420

The area of walls that needed to be painted = 231 feet²

Hence , the area of Melanie's wall to be painted is 231 feet²

The ratio is the division of the two numbers.

For example, a/b, where a will be the numerator and b, will be the denominator.

Proportion is the relation of a variable with another. It could be direct or inverse.

The ratio is the division and the ratio can be bigger than the amount which is put on the ratio or the ratio could be smaller than the amount which is put on the ratio. It depends upon whether the numerator is big or small than the denomintor.

Given the condition in the question let's suppose the number is x then

seven-time is 7x and 5 means 7x + 5.
