Tickets to a school production cost $5 for a student ticket and $10 for an adult ticket. A total of 67 tickets were purchased at a cost of $440.Which value could replace c in the table?

A. 67
B. 440
C. 67 – a
D. 440 – a

Answers

Keywords:

System of equations, variables, cost, tickets, adults, children.

For this case we must solve a system of equations with two variables represented by the tickets of students and adults of a school production.

We define the variables according to the given table:

a: Number of tickets sold to adults
c: Amount of tickets sold to children.

We then have the following system of equations:

$a + c = 67\n10a + 5c = 440$

From the first equation, we clear the value of the variable c:

$c = 67-a$

Answer:

The value that could replace c in the table is:

$c = 67-a$

Option C

Answer:

C= 67-A

Answer:

(A) 44.7°

Step-by-step explanation:

Use the law of cosines:

$cos A=(b^2+c^2-a^2)/(2bc)$
$cos A=(25^2+31^2-22^2)/(2*25*31)=0.711$
m∠A = arccos(0.711) ≈ 44.7°

Using law of cosines

$\n \sf\longmapsto cosA=(b^2+c^2-a^2)/(2bc)$

$\n \sf\longmapsto cosA=(25^2+31^2-32^2)/(2(25)(31))$

$\n \sf\longmapsto cosA=(625+961-484)/(1550)$

$\n \sf\longmapsto cosA=(1102)/(1550)$

$\n \sf\longmapsto cosA=0.7109$

$\n \sf\longmapsto A=cos^(-1)(0.7109)$

$\n \sf\longmapsto A=44.7°$

a chess player played 20 games total. if he won 2 of the games, what is the ratio of games he lost to games he won?

Answers

$20-2=18\n\sf\nSo,~ he~ lost~ 18~ games.\n\ngames~ lost:games~ won\n\nThe~ ratio ~is \n18:2\n\nWhich~ can~ be~ simplified ~to\n9:1$

1. Find the ratio of the Chess player in where he played a total of 20 games and won 2 of the games.
Ratio is considered as the quantitative relationship between to numbers that show the value of both sides.
Now, in the chess game, there are 20 games in all and he won 2 games. To get the ratio of his lose and win, simply subtract 2 from 20
=> 20 -2 = 18
thus, the ratio of the chess game is
=> 18 : 2
=> 18 is the lose
=> 2 is the win.

The table shows the population of a small town over time. The function P = 10,550(1.1)x models the population x years after the year 2000. The function P = 10,550(1.1)x models the population x years after the year 2000. For which year would this model most likely be sufficient to make a prediction of the population? 1950 2005 2025 2050

Answers

Answer:
2005 would be the most sufficient date to use this model for.

Explanation:
The model is using a short amount of time as its basis, we would not want to go too far into the future.
It would likely be less and less accurate the later we go. We also can't use 1950 because the function looks for years after 2000.

Answer:

the answer is B
