Find AD.BA13x 4D8x + 11

Answers

Answer 1

Answer:

Step-by-step explanation:

13x-4 = 8x+11

13x-4 = 8x+11

-8x       -8x

5x-4=11

+4    +4

5x=15

/5   /5

x=3

Plug it in...

13(3) -4

39-4

=35

Answer 2

The value of AD is: AD = 35.

Here, we have,

from the given figure, we get,

both the triangles are similar to each other.

so, we have,

AD = DC

i.e.

13x-4 = 8x+11

To solve the equation 13x - 4 = 8x + 11, we need to isolate the variable x on one side of the equation.

Here are the steps:

Start by moving the terms with x to one side of the equation.

We can do this by subtracting 8x from both sides:

13x - 8x - 4 = 8x - 8x + 11

Simplifying the left side:

5x - 4 = 11

Next, move the constant term (-4) to the other side by adding 4 to both sides of the equation:

5x - 4 + 4 = 11 + 4

Simplifying:

5x = 15

To isolate x, divide both sides of the equation by the coefficient of x, which is 5:

(5x)/5 = 15/5

Simplifying:

x = 3

Therefore, the solution to the equation 13x - 4 = 8x + 11 is x = 3.

so, we get, x = 3

Plug it in AD, we have,

13(3) -4

=39-4

=35

Hence, The value of AD is: AD = 35.

Which expression can you use to find the total price of 5 concert tickets




(from Iready)

Answers

Answer:

5t + 2

Step-by-step explanation:

Given that :

Total cost of ticket = t + 2

t = price of one ticket ; the constant digit, '2' is the service fee.

The service fee being a constant amount during the purchase of concert ticket will be paid per service transaction done.

To purchase 5 concert ticket, total cost will be :

Ticket price for 5 tickets plus a service fee

5 * ticket price plus a constant service fee

5 * t + 2

Ginger buys lunch at school every day. She always gets
pizza when it is available. The cafeteria has pizza about
80% of the time.
Ginger runs a simulation to model this using a random
number generator. She assigns these digits to the possible
outcomes for each day of the week:
Let 0 and 1 = no pizza available
• Let 2, 3, 4, 5, 6, 7, 8, and 9 = pizza available ​

Answers

Answer:

The estimated probability that Ginger will eat a a pizza everyday of the week is;

D. 8/10 = 80%

Step-by-step explanation:

The given parameters are;

The frequency with which Ginger buys launch = Everyday

The percentage of the time the cafeteria has pizza out = 80%

The outcome of 0 and 1 = No pizza available

The outcome of 2, 3, 4, 5, 6, 7, 8, and 9 = Pizza available

Therefore, we have the;

Group number  [tex]{}[/tex]                          Percentage of time pizza available

1                     [tex]{}[/tex]                          80%

2                     [tex]{}[/tex]                          80%

3                     [tex]{}[/tex]                          80%

4                     [tex]{}[/tex]                          80%

5                     [tex]{}[/tex]                          40%

6                     [tex]{}[/tex]                          100%

7                     [tex]{}[/tex]                          80%

8                     [tex]{}[/tex]                          100%

9                     [tex]{}[/tex]                          80%

10                     [tex]{}[/tex]                          80%

Therefore, the sum of the percentages outcome the days Ginger eats pizza = 0.8 + 0.8 + 0.8 + 0.8 + 0.4 + 1 + 0.8 + 1 + 0.8 + 0.8 = 8

The number of runs of simulation = 10 runs

The estimated probability that Ginger will eat a a pizza everyday of the week = (The sum of the percentages outcome the days Ginger eats pizza)/(The number of runs of simulation)

∴ The estimated probability that Ginger will eat a a pizza everyday of the week = 8/10

Step-by-step explanation:

There is a common difference d between consecutive terms, that is

This indicates the sequence is arithmetic with n th term

Here, [tex]A(t)[/tex] = the final amount

[tex]500=[/tex] Initial amount

b) Find all sides and angles when b= 2 and c=6

Answers

Answer:

Step-by-step explanation:

a.)

<A = 90 - 67 = 23*      A = (a^2 + 14.72^2 = 16^2) = a = 6.25

<B = 67*                      B = (sin67 = b/16) = sin67*16 = 14.73

<C = 90*                      C = 16

b.)

a = (a^2 + 2^2 = 6^2) = a = 5. 66         <A = (cosA = 2/6) = 70.53*

b = 2                                                      <B = 90-70.53 = 19.47*

What is an equation in point-slope form for the line that contains the points (-1, 4) and (11, -6)?

Answers

Answer:

The equation in point-slope form is [tex]y-4=-\frac{5}{6}(x+1)[/tex]

Step-by-step explanation:

Given points are;

(-1, 4) and (11, -6)

We will find the slope of the line through the given points.

Slope = m = [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]

m = [tex]\frac{-6-4}{11-(-1)}[/tex]

m = [tex]\frac{-10}{12}[/tex]

m = [tex]\frac{-5}{6}[/tex]

Point slope form of a line is given by;

[tex]y-y_1=m(x-x_1)[/tex]

Putting the point (-1,4) and slope in the equation

[tex]y-4=-\frac{5}{6}(x-(-1))\\y-4 =-\frac{5}{6}(x+1)[/tex]

Hence,

The equation in point-slope form is [tex]y-4=-\frac{5}{6}(x+1)[/tex]
