Answer:

√2 is irrational

Step-by-step explanation:

√2 is irrational because you cannot write it as a fraction of rational numbers. Some good approximations of √2, however, are 99/70, 577/408, and 665857/470832.

Answer:

y = 2x

Step-by-step explanation:

Use y = mx + b to write an equation. The y-intercept is zero. This is where the line crosses the y -axis, kind of the "starting point" So in the equation the b is a zero.

You can grab a couple points from the line to do a calculation for slope. BUT, you can actually SEE the slope on this line and save yourself the calculation. Starting from zero, see that you go UP 2 and OVER 1 to get to the next point. UP2OVER1 gets you to the next point and the next point. UP2OVER1 is the slope 2/1, which is 2, which is the m in the equation.

y = 2/1 x + 0

y = 2x + 0

y = 2x

**in case you have to show a calc for slope. Grab two points and do y-y, put that on top and then x-x and put that on the bottom.**

Answer:

C. 6cm and 7 cm

Step-by-step explanation:

The volume of a cube is calculated by finding the third power of a side length which is basically multiplying the value by itself three times (a^3 = a*a*a)

Let a represent the side length

a^3 = 250.047 cm^3 (approximately 250) we can try each option one by one to find the nearest result:

A)

the third power of 4 is 64 and the third power of 5 is 125 so this is not the answer we are looking for

B)

The third power of 5 is 125 and the third power of 6 is 216 so this is also not the answer we are looking for

C)

the third power of 6 is = 216 and the third power of 7 is 343

now 250 is between these values so this is the answer we are lookign for

Answer:

68

Step-by-step explanation:

The shape is 5 sides polygon.

Sum of interior angles of a 5 sided polygon = 540,

7x + 4 + 8x + 3 + 4x + 8 + 10x - 4 + 6x + 4 = 540

7x + 8x + 4x + 10x + 6x + 4 + 3 + 8 + 4 - 4 = 540

35x + 4 + 3 + 8 = 540

35x + 15 = 540

35x = 540 - 15

35x = 525

Divide 35 on both sides,

x = 525 / 35

x = 15

Angle R = 4x + 18

Substitute the value of x,

Angle R = 4 ( 15 ) + 8

             = 60 + 8

Angle R = 68

Answer:

1.2

Step-by-step explanation:

9.2 + 8d = 73.2

d = 8

then first term is   9.2 - d = 1.2

The first term of an arithmetic sequence is 1.2 with a common difference of 8.

It is defined as the systematic way of representing the data that follows a certain rule of arithmetic.

We have:

Tenth term of an arithmetic sequence = 73.2  or

a+(10-1)d = 73.2 ....(1)

Second term of an arithmetic sequence = 9.2 or

a+(2-1)d = 9.2 .....(2)

Where a is the first term and d is a common difference.

Solving equations (1) and (2)

From the equation (2) put the value of d in the equation (1), we get:

a+9(9.2-a) = 73.2

a+82.8 - 9a = 73.2

-8a = -9.6

a = 1.2

Thus, the first term of an arithmetic sequence is 1.2 with a common difference 8.

Answer:

$7,350.00

Step-by-step explanation:

To find out the total amount of money, you need to know the total amount of tickets sold.

So, find out what 20% of 350 is for the second hour and add it to the 350 from the first hour

350 x 0.20 = 70

350 + 70 = 420 total tickets

now you multiply 420 by the amount of money per ticket in order to know the price for all the tickets in both hours

420 x 17.50 = 7,350 dollars total

Answer:

10 9/64

Step-by-step explanation:

To answer this, multiply '1 3/8 miles' by '7 3/8.'  

The improper fraction form of '1 3/8' is 11/8, and that of 7 3/8 is 59/8.

Multiplying 11/8 by 59/8, we get 649/64, or (as a mixed number) 10 9/64

Answer:

Asymptotic discontinuities at [tex]x = (-2)[/tex] and [tex]x = 4[/tex].

Step-by-step explanation:

A linear function has an asymptotic discontinuity at [tex]x = a[/tex] if [tex](x - a)[/tex] is a factor of the denominator after simplification.

The numerator of this function, [tex](x - 1)[/tex], is linear in [tex]x[/tex].

The denominator of this function, [tex](x^{2} - 2\, x - 8)[/tex], is quadratic in [tex]x[/tex]. Using the quadratic formula or otherwise, factor the denominator into binominals:

[tex]\begin{aligned}y &= \frac{(x - 1)}{x^{2} - 2\, x - 8} \\ &= \frac{(x - 1)}{(x - 4)\, (x + 2)}\end{aligned}[/tex].

Simplify the function by liminating binomials that are in both the numerator and the denominator.

Notice that in the simplified expression, binomial factors of the denominator are [tex](x - 4)[/tex] and [tex](x + 2)[/tex] (which is equivalent to [tex](x - (-2))[/tex].) Therefore, the points of discontinuity of this function would be [tex]x = 4[/tex] and [tex]x = (-2)[/tex].

Answer:

x + y = 9

Step-by-step explanation:

Line is passing through the points (9, 0) and (0, 9)

-> y - intercept (b) = 9

& slope (m) = (9 - 0)/(0 - 9) = 9/(-9) = -1

Equation of line in slope-intercept form is given as:

y = mx + b

Plugging in the values of m and b in the above equation, we find:

y = (-1)x + 9

-> y = -x + 9

-> x + y = 9

This is the required equation of the line

[Note: there are several other points through which line is passing and those points can also be selected for finding the required equation]

The cost of 1 purse will be £14.

And, The cost of 1 watch will be £13.

What is an expression?

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

Given that;

The cost of 1 purse and 1 watch is £27.

The cost of 2 purses and 1 watch is £41.

Now,

Let the cost of 1 purse = x

And, The cost of watch = y

So, We can formulate;

⇒ x + y = £27    ......(i)

And, The cost of 2 purses and 1 watch is £41.

So, We can formulate;

⇒ 2x + y = £41          ..........(ii)

Subtract (i) from (ii), we get;

⇒ 2x + y - x - y = 41 - 27

⇒ x = £14

And, From equation (i), we get;

⇒ x + y = £27

⇒ £14 + y = £27

⇒ y = £27 - £14

⇒ y = £13

Thus, The cost of 1 purse will be £14.

And, The cost of 1 watch will be £13.

Here is how you solve for x:

9x - 43/ 3x + 29

1: First, you add like terms. In this case, it is 9x and 3x. 9x + 3x= 12x

2: Then, you have -43 and 29 left. -43 + 29= -14 because you do 43 - 29 and keep the sign of the larger number.

3: Lastly, we have a one-step equation left to solve: 12x-14. So, now we do this:

- divide both sides by 12.

- -14/12= 1.67

x= -1.67
