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:

5.23 =d

Step-by-step explanation:

cost = fee + daily charge*days

520 = 180+ 65d

Subtract 180

520 -180 = 180+65f-180

340 = 65d

Divide by 65

340/65 = 65d/65

5.23 =d

Answer:

Solution given:

5(x+2) = 11

dividing both side by 5

5(x+2)/5=11/5

x+2=11/5

subtracting both side by 2

x+2-2=11/5-2

x=11/5-2

x={11-2*5}/5[taking l.c m

x={11-10}/5

x=1/5

x=1/5is a required answer.

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:

A

Step-by-step explanation:

The sum of the 3 angles in a triangle = 180°

Sum the 3 angles and equate to 180

4 + 3x + 3x + 14 + 90 = 180 , simplify left side

108 + 6x = 180 ( subtract 108 from both sides )

6x = 72 ( divide both sides by 6 )

x = 12

Then

∠ A = 4 + 3x = 4 + 3(12) = 4 + 36 = 40° → A

Answer:

CD = 400. CD = − C (100) + D (500) = 400. 1 = I 5 = V 10 = X 100 = C 500 = D 1,000 = M.

Step-by-step explanation:

We are given the two functions:

[tex]f(x)=x^2+1\text{ and } g(x)=x-4[/tex]

And we want to find:

[tex](f\circ g)(10)[/tex]

This is equivalent to:

[tex]=f(g(10))[/tex]

Find g(10) first:

[tex]g(10)=(10)-4=6[/tex]

Substitute:

[tex]f(g(10))=f(6)[/tex]

Evaluate f(6):

[tex]f(6)=(6)^2+1=37[/tex]

Therefore:

[tex](f\circ g)(10)=37[/tex]

Our answer is A.

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:

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:

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

b = 9

Step-by-step explanation:

Step 1: Define

Identify

[tex]\displaystyle f(x) = \left \{ {{-1 - x, \ x \neq 2} \atop {8, \ x = 2}} \right.[/tex]

[tex]\displaystyle \lim_{x \to -0.5} f(x)[/tex]

Step 2: Solve

According to the graph, we see that when we approach x = -0.5 of the function f(x), we land on y = -0.5.

The function value at x = 2 would equal 8, but the limit as x approaches -0.5 would not approach the function value, but approach the hole in the function.

Answer:

4

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)

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
