is 10227 a rational number?

Answers

Answer:

Yes, 10227 is a rational number

Step-by-step explanation:

10227 is whole number, an integer, a counting number. For a number to be rational it has to be a integer, a counting number, a whole number, a fraction, and a terminating decimal. A decimal that repeats like 3.3333 is also rational because it can be predicted. Pi or 3.14 is not predictable

Rectangle ABCD is rotated 95° about point Q to create rectangle A'B'C'D'.

What is the area of rectangle A'B'C'D'?

Answers

Answer:

12

Step-by-step explanation:

Since both rectangles are of the same dimensions, simply multiply the width of the first box(2) and the length of the second box(6) together(2*6 = 12)

The area of rectangle before and after the 95° degrees rotation about point Q will be same.

What is the area of a Rectangle?

The area of a rectangle is the product of its length and width. Mathematically -

Area = length x width

Given is Rectangle ABCD is rotated 95° about point Q to create rectangle A'B'C'D'

The area of a rectangle depends on its length and width and not on its orientation. When a rectangle ABCD is rotated 95° about point Q to create rectangle A'B'C'D', in such case there will be no change in the dimensions of a rectangle. Therefore, the area of rectangle will remain same, irrespective of its orientation in plane.

Therefore, the area of rectangle before and after the 95° degrees rotation about point Q will be same.

-66 = -9n + 16n + 4
Solve these step by step pls

Answers

Answer:

n= -10

Step-by-step explanation:

-66=7n+4

-7n=4+66

-7n=70

n=70/-7

n= -10

Answer:

n = -10

Step-by-step explanation:

-66 = -9n + 16n + 4

1. I started by subtracting 4 on both sides of the equation this gives you -70 = -9n + 16n

2. I then combined the like terms 16n and -9n on the right side of the equation. We do this by subtracting 9n from 16n. Which gives you -70 = 7n

3. We then divide both sides by 7 in order to get -10 = n

This gives you your final answer of n = -10

    Hypotenuse  = 3cm

Unknown:

Adjacent and opposite sides = ?

Solution:

In this triangle, the adjacent and opposite sides are equal to one another. So,

 Let adjacent  = y

        opposite  = y

For right angle triangles as this, using the Pythagoras theorem,

           hypotenuse²  = adjacent² + opposite²

 Insert the parameters and solve;

                    3² = y² + y²

Reset
Next

Answers

Answer:

Equation A: x = -1 and y = 3

Equation B: x = 12 and y = 16

Step-by-step explanation:

In the complex numbers (a + bi) and (x + yi)

(a + bi) + (x + yi) = (a + x) + (b + y)i(a + bi) - (x + yi) = (a - x) + (b - y)i

Equation A

(x + yi) + (4 – 7i) = 3 – 4i

∴ (x + 4) + (y - 7)i = 3 - 4i

→ Compare the real parts and compare the imaginary parts

x + 4 = 3 and y - 7 = -4

∵ x + 4 = 3

→ Subtract 4 from both sides

∴ x + 4 - 4 = 3 - 4

x = -1

∵ y - 7 = -4

→ Add 7 to both sides

∴ y - 7 + 7 = -4 + 7

y = 3

Equation B

(x + yi) - (-6 + 14i) = 18 + 2i

∴ (x - -6) + (y - 14)i = 18 + 2i

→ (-)(-) = (+)

∴ (x + 6) + (y - 14)i = 18 + 2i

→ Compare the real parts and compare the imaginary parts

x + 6 = 18 and y - 14 = 2

∵ x + 6 = 18

→ Subtract 6 from both sides

∴ x + 6 - 6 = 18 - 6

x = 12

∵ y - 14 = 2

→ Add 14 to both sides

∴ y - 14 + 14 = 2 + 14

y = 16

A city taxi driver charges $2 per kilometer and has a starting fee of $9. An Uber driver charges $5 per kilometer, but has no starting fee. At which distance (in kilometers) will the price of taking an Uber be equal to the price of taking a city taxi?

Answers

Answer:

Taxi Driver: 9+2x=

Uber Driver: 5x=

So we just gotta keep multiplying until we find where they’re equal. So let’s assume that when we can get the Taxi Drivers price to have a 5 in the tens place or a 0 in the tens place. By the looks of it, they will meet at 15$ for that to happen let x=3, which would make the taxi driver’s equation 9+2(3), 9+6=15$, and the uber driver’s equation would be 5(3)=15$. X=3 or X=distance in kilometers.

What is the slope of the line that passes through the points (-8, -6) and (-18, 6) ? Write your answer in simplest form.

Answers

Answer:

y=12/10-15.6

Step-by-step explanation:

The slope of the line is [tex]-\frac{6}{5}[/tex].

To understand more, check below explanation.

Slope of line:

The slope of line passing through [tex](x_{1}, y_{1})[/tex] and [tex](x_{2}, y_{2})[/tex] is computed as,

                    [tex]m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}[/tex]

Given that , points are (-8, -6) and (-18, 6)

So that,

               [tex]Slope=\frac{6-(-6)}{-18-(-8)}\\ \\Slope=\frac{12}{-10}\\ \\Slope=-\frac{6}{5}[/tex]

if you flip three coins, the probability of getting three heads is 1/8. Interpret this probability.

Answers

Suppose you have a fair coin: this means it has a 50% chance of landing heads up and a 50% chance of landing tails up. Suppose you flip it three times and these flips are independent. So the probability that it lands heads up, then tails up, then heads up is 1/8, or 12.5%.
(Also you can use the formula for that.

The interpretation of the probability is there is a 12.5% chance of obtaining three heads when three coins are flipped

The probability is given as:

[tex]\mathbf{Pr = \frac 18}[/tex]

The above represents the probability of flipping a head three times.

Express as decimal

[tex]\mathbf{Pr = 0.125}[/tex]

Express as percentage

[tex]\mathbf{Pr = 12.5\%}[/tex]

This means that, there is a 12.5% chance of obtaining three heads when three coins are flipped
