Step-by-step explanation:

If and only if this is a right triangle, we can apply the some fimctopm to determine the length of side BD:

side BC

tan 20 degrees = ---------------

or side BC = 8 tan 20 degrees. Since tan 20 degrees = 0.364 radians,

side BC has length 8(0.364) = 2.91 units

A ticket service is selling tickets to a concert. An order of 4 tickets has a price of $63 and an order of 6 tickets has a price

Valentin [98]

Answer:

x = Number of tickets for the concert

y = Price of the order of x tickets

y = 14.5x + 5

Step-by-step explanation:

1. Let's review the information given to us to answer the question correctly:

Order of 4 tickets has a price of $63

Order of 6 tickets has a price of $92

2. Write an equation to find the price of any amount of tickets.

Let's find out the price of a ticket to understand if there's a service fee and how much is it, this way:

Price of a ticket = (Order of 6 tickets - Order of 4 tickets)/2

Price of a ticket = (92 - 63)/2

Price of a ticket = 29/2 = 14.50

If a ticket costs $ 14.50, 4 tickets will cost $ 58 and 6 tickets will cost $ 87, therefore there is a service or delivery fee of $ 5.

Order of 4 tickets - Price of 4 tickets = Service or delivery fee

Replacing, we have:

63 - 58 = 5

Order of 6 tickets - Price of 6 tickets = Service or delivery fee

Replacing, we have:

92 - 87 = 5

Now, we can write the equation to find the price of an order of any amount of tickets, this way:

x = Number of tickets for the concert

y = Price of the order of x tickets

y = 14.5x + 5

Five girls participated in

mestny [16]

Answer:

Ella ............> Maria .............> Sarah ............> Marianne .............> Julia

Explanation:

1- For the first given:

Maria finished before Sarah, but behind Ella

So, we can infer that:

Ella finished first, followed by Maria and then Sarah

Ella ............> Maria .............> Sarah

2- For the second given:

Marianne finished before Julia, but behind Sarah

So, we can infer that:

Sarah finished first, followed by Marianne and then Julia

Sarah ............> Marianne .............> Julia

3- Combining the above parts:

By combining what we got from parts 1 and 2, we can deduce that:

Ella finished first, followed by Maria, Sarah, Marianne and finally Julia

Ella ............> Maria .............> Sarah ............> Marianne .............> Julia

Hope this helps :)

Anusha is walking on a hiking trail at a rate of 3/4 miles in 1/4 hour. At this rate, how far will Anusha walk in an hour?

kherson [118]

3 miles. Using cross-multiplication, 3×4 = 12 and 4×1 = 4, so 12/4 = 3.

Which method is most efficient in solving a system of linear equations when two equations have x values with opposite coiffiecen

bulgar [2K]

Answer:

Elimination

Step-by-step explanation:

A system of equations is 2 or more equations for which the same x,y solution exists. We can solve the system in three ways: elimination, substitution, or graphing. Elimination is the best method when we have standard form equations and x values with opposite coefficients. This is so because the x variable will eliminate easily and allow us to solve for y.
