Which number is an irrational number? A. B. C. D.

Answer:

In 2020 the population will be 6,233.

Step-by-step explanation:

Giving the following information:

Present value (PV)= 5,600

Growth rate (g)= 1.8%

Number of periods= 6 years

To calculate the population in 2020, we need to use the following formula:

FV= PV*(1 + g)^n

FV= 5,600*(1.018^6)

FV= 6,232.67 = 6,233

In 2020 the population will be 6,233.

Answer:

1/2

Step-by-step explanation:

Pick two points on the line

(0,-4) and (2,-3)

Using the slope formula

m = (y2-y1)/(x2-x1)

    = (-3 - -4)/(2 -0)

    (-3+4)/(2-0)

    1/2

Given:

The faces on a number cube are labeled 1,2,2,3,4, and 5.

The number cube is rolled 114 times.

To find:

How many times would you expect the number 2 to appear?

Solution:

We have,

Total outcomes = 1,2,2,3,4, and 5.

Number of total outcomes = 6

Favorable outcomes = 2 and 2

Number of favorable outcomes = 2

The probability of getting 2 is:

[tex]P(2)=\dfrac{\text{Number of favorable outcomes}}{\text{Number of total outcomes}}[/tex]

[tex]P(2)=\dfrac{2}{6}[/tex]

[tex]P(2)=\dfrac{1}{3}[/tex]

Now, the expected number of times when 2 to appear is:

[tex]E(x)=114\times P(2)[/tex]

[tex]E(x)=114\times \dfrac{1}{3}[/tex]

[tex]E(x)=38[/tex]

Therefore, the expected number of times is 38.

Answer:

133.33%

Step-by-step explanation:

x/y * k = 1.6x / 1.2y

k = (1.6x / 1.2y) / (x/y)

k = 1.6/1.2

k = 4/3 = 1.3333 = 133.33%

Answer:

Choice C (the third option)

Step-by-step explanation:

[tex](a+b)(a+b) = a^2+2ab+b^2[/tex]

Choice C is incorrect because it is missing the [tex]2ab[/tex]. Hope this helped!

The volume, of the cement used to make the sidewalk is 8 ft³

Volume is defined as the space occupied within the boundaries of an object in three-dimensional space. It is also known as the capacity of the object.

Given that, James is using cement to make a new sidewalk and new steps,

He will make a new rectangular sidewalk that is 8 feet long, 4 feet wide, and 0.25 foot thick.

Volume = length x width x height

Volume = 8 x 4 x 0.25 = 8 ft³

Hence, the volume, of the cement used to make the sidewalk is 8 ft³

Answer:

9

Step-by-step explanation:

A = B + 2

C = B - 3

A x C = 66

A = Andrew

C = Chris

B = Beatrice

Multiply A and c together

(B + 2) x (b - 3)

b^2 - 3b + 2b - 6

b^2 -b - 6 = 66

b^2 - b - 72 = 0

factors of -72b^2 that add up to - b are -9b + 8b

b^2 + 8b -9b - 72

b (b + 8) -9(b + 8)

b = 9 or - 8

Answer:

-5

Step-by-step explanation:

Answer:

-5

Step-by-step explanation:

The result is positive, so you know the number must be negative. What two numbers normally make 60? That would be 5 and 12, but since the 12 is negative (-12), that means the 5 must be negative (-5). So, the answer is -5.

Answer:

x = 28

y = 47

Step-by-step explanation:

40 + 5x = 180 since it forms a straight line

5x = 180-40

5x = 140

Divide by 5

5x/5 = 140/5

x =28

3y-1 = 5x  since they are alternate exterior angles

3y-1 = 140

Add 1

3y = 141

3y/3 = 141/3

y = 47

Step-by-step explanation:

7x = x² - 8

=> x² - 7x - 8 = 0

use quadratic formula:

a = 1, b = -7, c = -8

x = [tex]\frac{-(1)±\sqrt{(-7)^{2} - 4(1)(-8) } }{2(1)}[/tex] (pls ignore the "A" I don't know why it's showing up)

=> x = [tex]\frac{-1±\sqrt{49 + 32} }{2}[/tex]

=> x = [tex]\frac{-1±9 }{2}[/tex]

=> x = [tex]\frac{-1 +9}{2}[/tex] = 4 or [tex]\frac{-1-9}{2}[/tex] = -5 (the answer is only 4 since it's asking for the positive solution)
