What is the missing value in the following arithmetic sequence?

Answers

3.8 - 2 = 1.8

so
5.6 + 1.8 = 7.4

missing is 7.4

answer is C. 7.4

Answer:

Step-by-step explanation:

Alright, lets get started.

The first term is 2 and the second term is 3.8.

It means the common difference is [tex]3.8-2 = 1.8[/tex]

So, adding common difference :

First term = 2

Second term = 3.8

Third term = [tex]3.8+1.8=5.6[/tex]

Fourth term = [tex]5.6+1.8 = 7.4[/tex]

So the answer is 7.4   :   answer

12 ticket sellers, 25 cleaning persons, and 15 ushers employees will be paid $10, $7.50, 8.50 per hour for 50 hours per month what is the monthly salary

Answers

----------------------------------------------------------
Ticket Sellers
----------------------------------------------------------
1 ticket seller  = $10 x 50
1 ticket seller  = $500

12 ticket sellers = $500 x 12
12 ticket sellers = $6000

----------------------------------------------------------
Cleaning person
----------------------------------------------------------
1 cleaning person = $7.50 x 50 
1 cleaning person = $ 375

25 cleaning person = $375 x 25
25 cleaning person = $9375

----------------------------------------------------------
Ushers
----------------------------------------------------------
1 usher = $8.50 x 50
1 usher = $425

15 ushers = $425 x 15
15 ushers = $6375

----------------------------------------------------------
Total
----------------------------------------------------------
$6000 + $9375 + $6375 = $21750

A large bag of marbles contains an equal amount of red, orange, yellow, blue, and green marbles. Brody randomly selects 1 marble from the bag. Which of the following represents the probability of selecting a red, blue, yellow, or green marble
A) 0.8
B) 0.7
C) 0.9
D) 0.6

Answers

the answer will be
[tex] \frac{4}{5} = 0.8[/tex]
hope this helps

Answer:  The correct option is (A) 0.8.

Step-by-step explanation:  Given that a  large bag of marbles contains an equal amount of red, orange, yellow, blue, and green marbles. Brody randomly selects 1 marble from the bag.

We are to find the probability of selecting a red, blue, yellow or green marble.

Let n be the number of each color of marbles in the bag.

That is, the number of red, orange, yellow, blue, and green marbles, each equals n.

Let S denote the sample space of selecting a marble from the bag and A denote the event of selecting a red, blue, yellow or green marble.

Then, we have

n(S) = n + n + n + n + n = 5n,

n(A) = n + n + n + n = 4n.

Therefore, the probability of event A is given by

[tex]P(A)=\dfrac{n(A)}{n(S)}=\dfrac{4n}{5n}=\dfrac{4}{5}=0.8.[/tex]

Thus the required probability selecting a red, blue, yellow or green marble is 0.8.

Option (A) is CORRECT.

Can someone please help me solve for x and y? Thank you

Answer: 
Choice D) x*y = -10

============================================

Explanation:

Multiply both sides of the first equation by 10 to clear out the fractions (10 is the LCD)
3x/5 + y/2 = 13/10
10*(3x/5 + y/2) = 10*(13/10)
6x + 5y = 13

Multiply both sides of the second equation by 100 to get each decimal value to turn into a whole number (move the decimal point over 2 spots to the right)
0.5y + 0.04x = 2.42
50y + 4x = 242
4x + 50y = 242

So we have this new system of equations which is equivalent to the original system
6x + 5y = 13
4x + 50y = 242

Multiply both sides of the top equation by 10 so that the 5y turns into 50y
6x + 5y = 13
10*(6x + 5y) = 10*13
60x + 50y = 130

Now we have this system of equations
60x + 50y = 130
4x + 50y = 242

If we subtract straight down then we have
60x-4x = 56x
50y-50y = 0y = 0 ... notice how the y terms go away effectively
130-242 = -112

The y terms go away leaving us with this simplified equation
56x = -112
Which solves to
x = -2
when we divide both sides by 56

Now use that x value to find y
6x + 5y = 13
6(-2) + 5y = 13 ... replace x with -2
-12 + 5y = 13
-12+5y+12 = 13+12 ... adding 12 to both sides
5y = 25
5y/5 = 25/5 .... dividing both sides by 5
y = 5

In summary we have x = -2 and y = 5. Therefore, x*y = -2*5 = -10 is the answer

A sphere has a radius of 2x + 5. Which polynomial in standard form best describes the total surface area of the sphere? Use the formula S = 4pir2 for surface area of a sphere.

Answers

Start with the given formula for the surface area of a sphere.

[tex] S = 4 \pi r^2 [/tex]

Now substitute 2x + 5 in for r, the radius.
Then simplify the expression and write it in standard form.

[tex] S = 4 \pi (2x + 5)^2 [/tex]

[tex] S = 4 \pi (4x^2 + 20x + 25) [/tex]

[tex] S = 16 \pi x^2 + 80 \pi x + 100 \pi [/tex]

which are the solutions of the quadratic equation x^2=9x+6

Answers

You can use the quadratic equation to solve this once you have this set equal to zero. The answers would be roughly 9.6 and -0.6. 

The solutions of the quadratic equation [tex]\(x^2 = 9x + 6\)[/tex]are:

[tex]\[x = \frac{9 + \sqrt{105}}{2}\][/tex] and [tex]\[x = \frac{9 - \sqrt{105}}{2}\][/tex]

To find the solutions of the quadratic equation [tex]\(x^2 = 9x + 6\)[/tex], we need to rewrite it in standard quadratic form [tex]\(ax^2 + bx + c = 0\).[/tex]

Given:

[tex]\[x^2 = 9x + 6\][/tex]

Subtract [tex]\(9x\) and \(6\)[/tex] from both sides to get it in standard form:

[tex]\[x^2 - 9x - 6 = 0\][/tex]

Now, to solve this quadratic equation, we can factor it or use the quadratic formula:

The quadratic formula is:

[tex]\[x = \frac{-b \pm \sqrt{b^2-4ac}}{2a}\][/tex]

For our equation:

[tex]\[a = 1, b = -9, \text{ and } c = -6\][/tex]

Substituting these values into the quadratic formula:

[tex]\[x = \frac{-(-9) \pm \sqrt{(-9)^2-4(1)(-6)}}{2(1)}\]\[x = \frac{9 \pm \sqrt{81+24}}{2}\]\[x = \frac{9 \pm \sqrt{105}}{2}\][/tex]

So, the solutions of the quadratic equation [tex]\(x^2 = 9x + 6\)[/tex]are:

[tex]\[x = \frac{9 + \sqrt{105}}{2}\][/tex] and [tex]\[x = \frac{9 - \sqrt{105}}{2}\][/tex]

Equation 1:

Simplifying both the equations we get:

x = 4.5 and x = - 0.5

Equation 2:

If the function graphed is f(x), find f(1).
A) -4
B) -1/4

C) 0
D) 4

Answers

Answer: choice A) -4

-----------------------------------------------

Step 1) Draw a vertical line through 1 on the x axis

Step 2) Mark the point where the vertical line and the blue curve intersect (or cross each other)

Step 3) Draw a horizontal line through the point marked in step 2. Note how this horizontal line goes through -4 on the y axis. 

So the point (1,-4) is on the blue curve. This means if x = 1 is the input then y = -4 is the output. Recall that y = f(x). So f(x) = -4 is the output as well when the input is x = 1.

In short, this is why f(1) = -4
