Find the 8th term.

Answer:

Olive's age = 32

Lisbeth's age = 8

Step-by-step explanation:

Declaration

Let Eisbeths present age = x

Let Olive's age = y

Equations

(x - 2) = 1/5 (y - 2)

x + 4 = 1/3(Y + 4)

Solution

1st equation

(x - 2) = 1/5 (y - 2)                 Multiply both sides by 5

5(x - 2) = y - 2                       Remove the brackets

5x - 10 = y - 2                       Add 10 to both sides

5x -10+10 = y - 2+10            Combine

5x = y + 8                            Subtract 8 from both sides

5x - 8 = y + 8 - 8                 Combine

5x - 8 = y

2nd Equation

x + 4 = 1/3(y + 4)                 Multiply both sides by 3

3(x + 4) = y + 4                   Remove the brackets

3x + 12 = y + 4                     Subtract 3 from both sides

3x + 12 - 4 = y + 4 - 4          Combine

3x + 8 = y

Note Since y is the same in both equations, the left side of each can be thought of as equal to each other.

3x + 8  = 5x - 8                    Add 8  to both sides

3x + 8 + 8 = 5x - 8 + 8        Combine

3x + 16 = 5x                         Subtract 3x from both sides

3x - 3x + 16 = 5x - 3x           Combine

16 = 2x                                  Divide by 2

16/2 = 2x/2

8  = x

y = 3x + 8

y = 32

Answer:

-2 3/8

Step-by-step explanation:

since point A is left of 0, it means it is a negative value.

so, the positive answer options are automatically out.

then we see that point A is 2 full units and a little bit left of 0.

that means it has to be lower than -2 but higher than -3.

-22/7 = -3 1/7

so, that is too low.

-3 7/8 is too low.

so, that leaves -2 3/8 (confirmed also by the fact that A is a little bit higher than half between -2 and -3, which is the case for -2 3/8).

Using the permutation formula, it is found that the probability that the CDs end up in alphabetical order is:

[tex]p = \frac{1}{8,204,716,800}[/tex]

For this problem, the order in which the CDs are chosen is important, hence the permutation formula is used to solve this question.

The number of possible permutations of x elements from a set of n elements is given by:

[tex]P_{(n,x)} = \frac{n!}{(n-x)!}[/tex]

8 CDs are chosen from a set of 21, hence the number of ways they can be chosen is:

[tex]P_{(21,8)} = \frac{21!}{13!} = 8204716800[/tex]

Only one arrangement is in alphabetical order, hence the probability is:

Answer:

x = 25, y = 10

Step-by-step explanation:

I'll add a drawing of my own so that it's easier for me to explain, and for you to understand.  

Since line BC and line DE are parallel and line AE is being shared, angle ACB and angle CED will be the same. So the square will also be 3y.

Since line AB and line CD are parallel and line AE is being shared, angle CAB and angle ECD will be the same. So the heart will be 2x.

Now that we figured out two unknown angles, we can see that the two triangles share two angles with the same value. Since angles in a triangle add up to 180 (Added angles in every triangle are the same), the triangle shape (I drew) will be 4x.

We have a few clues to find the value of x and y.

1) 2x + 4x + 3y = 180 (all angles in a triangle add up to 180)

2) 3y + 2x = 180 - 100 (If you look near point C, we can see that 3y + 100 + 2x equals a flat line. A flat line equals 180)

We can use substitution. 3y + 2x can be replaced with 80.

So our new equation will be: 4x = 100

x = 25.

Now we can replace x with 25 in our second clue.

3y + 2(25) = 80

3y + 50 = 80

3y = 30

y = 10.

We can conclude that x = 25, and y = 10

Answer:

x = 25 and y = 10

Step-by-step explanation:

The arrows on the line segments mean the lines are parallel.

Therefore, the diagram shows two similar triangles, which means their interior angles are the same size.  (Refer to the attached diagram).

Interior angles of a triangle sum to 180°:

⇒ 2x + 4x + 3y = 180

⇒ 6x + 3y = 180

⇒ 3(2x + y) = 180

⇒ 2x + y = 60

⇒ 2x = 60 - y

Angles on a straight line sum to 180°:

⇒ 3y + 100 + 2x = 180

⇒ 2x + 3y = 80

⇒ 2x = 80 - 3y

Substitute the first equation into the second equation, and solve for y:

⇒ 60 - y = 80 - 3y

⇒ 60 + 2y = 80

⇒ 2y = 20

⇒ y = 10

Substitute the found value of y into one of the equations and solve for x:

⇒ 2x = 60 - 10

⇒ 2x = 50

⇒ x = 25

Therefore, x = 25 and y = 10.

The company should focus attention on 17515 people.

The term percentage means a denominator of 100. We can proceed to find the people to which the company must reach as follows;

The percentage that is over the age of 65, and immunocompromised =  27%

so;

27/100 × 50,000 = 13500 people

50,000 - 13500 = 36,500

Now;

11% of this number are under 65 and immunocompromised so;

11/100 ×  36,500 = 4015 people

Total number that the company should reach = 13500 + 4015  = 17515 people

Emil starts the day with 16 liters of lemonade if he is left with 4 liters by the end of the day. Computed using the fractional values given.

Let the initial quantity of lemonade with Emil be x liters.

Quantity sold by Emil in the morning = Half of his lemonade = (1/2)x liters, that is half fraction of x.

Quantity left with Emil = x - x/2 = x/2 liters, that is half fraction of x.

Quantity sold by Emil at lunchtime = Quarter of what was left = (1/4)(x/2) liters = x/8 liters, that is the one-eight fraction of x.

Quantity left with Emil = x/2 - x/8 = 3x/8 liters, that is the three-eight fraction of x.

Quantity sold by Emil in the afternoon = One-third of what was left = (1/3)(3x/8) liters = x/8 liters, that is the one-eight fraction of x.

Quantity left with Emil = 3x/8 - x/8 = x/4 liters, that is the quarter fraction of x.

Now, we are said that Emil closes for the day with 4 liters remaining.

Therefore, x/4 = 4, or, x = 4*4 = 16 liters.

Therefore, Emil started the day with 16 liters of lemonade.

Answer:

D(t)=60+23*sin(2*pi*t/24)+26*cos(2*pi*t/24)

Step-by-step explanation:

The temperature at any time t can be represented as:

D(t)=A+B*sin(2*pi*t/T)+C*cos(2*pi*t/T)

where A is the average temperature, B is the amplitude of the sine wave, C is the amplitude of the cosine wave, and T is the period.

In this case, we are given that the average temperature is 60, the high temperature is 73, and the low temperature is 47. We can therefore calculate that the amplitude of the sine wave is 23 and the amplitude of the cosine wave is 26. The period is 24 hours. Therefore, the equation for the temperature in terms of time is:

D(t)=60+23*sin(2*pi*t/24)+26*cos(2*pi*t/24)

Answer:

Step-by-step explanation:

x + 120 = 180

25 + x + y = 180

flipping the first equation 180 - 120 = 60 so x is 60.

so plug in 60 into the second equation

25 + 60 + y =180 --> 85 + y =180 flip equation 180 - 85 = 95

so y is 95

a. The unit rate is 9 d per t

b. Find the graph in the attachment

To graph the line, we need to find its gradient or unit rate

Since t has an increase of 0.20 units in t corresponds to an increase of 1.8 units in d.

The gradient or unit rate of change is m = change in d/change in t

= Δd/Δt

Since

So, substituting the values of the variables into the equation, we have

m = Δd/Δt

= + 1.8 units/+ 0.2 units

= 9 d per t

So, the unit rate is 9 d per t

To graph the function, we need to know the equation of the graph.

So, the equation of a graph in gradient form is

m = (y - y')/(x - x') where (x', y') = (0, 0) since the graphs both start at the origin

Since m = 9, we have

m = (y - y')/(x - x')

9 = (y - 0)/(x - 0)

9 = y/x

y = 9x

So, the equation of the line is y = 9x

For systems A and B we have:

1) Change the first equation in A by a multiple of itself. (the multiple is 1/3).

2) Yes, the systems are equivalent.

Here we have the systems of equations:

A:

-3x + 12y = 15

7x - 10y = -2

B:

-x + 4y = 5

7x - 10y = -2

Notice that the second equation is the same in both systems, so we only need to work with the first ones.

If we take the first equation in system A:

-3x + 12y = 15

If we divide both sides by 3, we get:

-x + 4y = 5

Which is the first equation of B.

So we just need to replace the first equation in system A by a multiple of itself to get system B.

Because of that, we conclude that both systems are equivalent (because are made of the same equations) which means that both systems have the same solutions.
