There are some numbers.

We have to choose the real and integers number.

Now,

Since, The integers are the number that is positive, negative and zero.

Hence,

1. The number 23 is a real number and it is also a integer.

And,

2. √9 = √3 x 3

        = 3

Thus, The number √9 = 3 is a real number and it is also a integer.

Answer:

86

Step-by-step explanation:

The pattern follows this rule:

Every time, the difference between current term and the succeeding term is 0.5 more than that of the current term and preceding term.

The difference between the current term and the preceding term is:

89.5 - 92.5 = 3

Hence, the next term of the sequence should be 3.5 less than the current term.

Hence, the next term is 89.5 - 3.5 = 86.

The riddle compares a lame elephant to the act of adding 19 and 4, where the answer lies in the wordplay of 'one-legged' (1+9+4) and 'too-free' (sounding like 23).

The question "Why is a lame elephant like adding 19 and 4?" appears to be a playful riddle rather than a straightforward math problem.

The answer to this riddle plays on the similarity in sound between the words 'lame' and the number '1' when saying 'one-legged' or '1-legged', as well as the sum of the numbers 19 and 4 being 23, which can sound like 'two' and 'three' or 'too-free' when spoken quickly.

To conclude, a lame elephant is like adding 19 and 4 because it is 'one legged' or could be jokingly considered 'too-free' to walk as it would if it weren't lame.

There are 27 skylights total.

The total number of skylights all together is 27.

To find the total number of skylights, we need to multiply the number of rows by the number of skylights in each row. In this case, there are 3 rows and 9 skylights in each row. So, we can calculate the total number of skylights as 3 x 9 = 27.

Sales tax paid by Donte = [tex]\frac{5.6}{100} (5)[/tex]

= 0.28

Sales tax paid by Trista = [tex]\frac{7}{100} (5)[/tex]

The extra tax paid by Trista = 0.35 - 0.28 = 0.07.

Hence, Trista paid $0.07 more than Donte.

Answer:  The required length and breadth of the rug are 46 yards and 189 yards respectively.

Step-by-step explanation:  Given that a rectangular rug has a perimeter of 470 yards. The width of the rug is 5 yards more than four times the length.

We are to find the length and width of the rug.

Let l represents the length of the rug. Then, the width of the rug will be

[tex]w=4l+5.[/tex]

According to the given information, we have

[tex]470=2l+2w\\\\\Rightarrow 470=2l+2(4l+5)\\\\\Rightarrow 470=2l+8l+10\\\\\Rightarrow 10l=460\\\\\Rightarrow l=\dfrac{460}{10}\\\\\Rightarrow l=46.[/tex]

So, the width is given by

[tex]w=4\times46+5=184+5=189.[/tex]

Thus, the required length and breadth of the rug are 46 yards and 189 yards respectively.

5 . x ÷ 7 = 10 or less

5 . 14 = 70 ÷ 7 = 10

The unknown number, when multiplied by five and divided by seven, has to result in a value of 10 or less. To find this number, we solve the inequality 5x / 7 <= 10 and find that x must be less than or equal to 14.

The question is asking for a number that, when multiplied by five and then divided by seven, yields a result of 10 or less. Let's denote the unknown number as x. We can put this into a mathematical inequality:

5x / 7 <= 10

To solve for x, we first multiply both sides by 7 to cancel the denominator on the left side:

5x <= 70

Then, we divide both sides by 5 to isolate x:

x <= 14

Therefore, the number must be less than or equal to 14.

I this it is true but don’t quote me on it

Answer:

q = 0

Step-by-step explanation:

Solving the given Equation for q : 3 + q + 9 = 12 we get Option (b) q = 6

In the given equation, 3 + q + 9 = 12, we need to solve for q. To do this, we first combine the constants on the left side of the equation: 3 + 9 = 12. This simplifies to 12 = 12. Now, our equation becomes q + 12 = 12.

Next, we want to isolate q on one side of the equation. To do this, we can subtract 12 from both sides: q + 12 - 12 = 12 - 12. This simplifies to q = 0.

However, we must be cautious. While q = 0 satisfies the original equation of 3 + q + 9 = 12, it does not satisfy the intermediate equation q + 12 = 12. In fact, any value of q will satisfy the intermediate equation since adding 0 to any number does not change its value.

Let's verify the other answer choices:

(a) q = 0: As we just discussed, q = 0 satisfies the intermediate equation but not the original equation.

(c) q = 18: If we substitute q = 18 into the original equation, we get 3 + 18 + 9 = 30, which is not equal to 12.

(d) q = 24: If we substitute q = 24 into the original equation, we get 3 + 24 + 9 = 36, which is not equal to 12.

Therefore, the correct answer is (b) q = 6, as q = 6 satisfies both the intermediate equation (6 + 12 = 12) and the original equation (3 + 6 + 9 = 12).

In summary, the correct value of q that satisfies the given equation is 6.

THE SQUARE PERIMETER X IS TWO THIRDS OF THE SQUARE PERIMETER Y. THE PERIMETER OF THE SQUARE Y IS TWO THIRDS OF THE PERIMETER OF THE SQUARE Z. THE AREA OF THE SQUARE X IS 16 CM2 WHAT IS THE AREA OF THE SQUARE Z?

Let

Px--------> the perimeter of square x

Py--------> the perimeter of square y

Pz--------> the perimeter of square z

Ax--------> the area of square x

Az--------> the area of square z

Step 1

Find the length side of the square x

we know that

[tex]Px=\frac{2}{3} Py[/tex] -------> equation A

[tex]Py=\frac{2}{3} Pz[/tex] -------> equation B

[tex]Ax=16\ cm^{2}[/tex]

[tex]Ax=x^{2}[/tex]

so

[tex]x^{2}=16[/tex]

[tex]x=4\ cm[/tex]

Step 2

Find the perimeter of square x

[tex]Px=4x[/tex]

substitute the value of x in the formula

[tex]Px=4*4=16\ cm[/tex]

Step 3

Find the perimeter of square y

use the equation A

[tex]Px=\frac{2}{3} Py[/tex]

solve for Py

[tex]Py=\frac{3}{2} Px[/tex]

substitute the value of Px

[tex]Py=\frac{3}{2}16=24\ cm[/tex]

Step 4

Find the perimeter of square z

use the equation B

[tex]Py=\frac{2}{3} Pz[/tex]

solve for Pz

[tex]Pz=\frac{3}{2} Py[/tex]

substitute the value of Py

[tex]Pz=\frac{3}{2} 24=36\ cm[/tex]

Step 5

Find the area of square z

we know that

the area of the square z is equal to

[tex]Az=z^{2}[/tex]

Find the length side of square z

[tex]Pz=4z[/tex]

[tex]Pz=36\ cm[/tex]

so

[tex]4z=36[/tex]

[tex]z=9\ cm[/tex]

substitute the value of z in the area's formula

[tex]Az=9^{2}=81\ cm^{2}[/tex]

therefore

the answer is

the area of the square z is [tex]81\ cm^{2}[/tex]

Answer:

The distance from Cleveland to Cincinnati on the second map is 8 cm.

Step-by-step explanation:

The distance from Cleveland to Cincinnati is 40 cm on the first map and the scale on the first map is 1 cm to 10 km.

So, the actual distance from Cleveland to Cincinnati [tex]=(40*10) km = 400 km[/tex]

Suppose, the distance from Cleveland to Cincinnati on the second map is  [tex]d[/tex] cm.

Given that, the scale on the second map is 1 cm to 50 km. So, the equation will be........

[tex]\frac{d}{400}=\frac{1}{50}\\ \\ 50d=400\\ \\ d=\frac{400}{50}=8[/tex]

So, the distance from Cleveland to Cincinnati on the second map is 8 cm.

The distance from Cleveland to Cincinnati on the second map can be found to be 8 cm.

To find the actual distance from Cleveland to Cincinnati, you would multiply the map distance by the scale:

= 40 cm * 10 km/cm

= 400 km

So, the actual distance from Cleveland to Cincinnati is 400 km.

Now, on the second map, the scale is 1 cm to 50 km.

To find the distance from Cleveland to Cincinnati on the second map, you would divide the actual distance by the scale of the second map:

= 400 km / 50 km/cm

= 8 cm

So, the distance from Cleveland to Cincinnati on the second map would be 8 cm.
