Given the sizes of the angles as<br> specified in the picture, how large is<br> angle 1?
Dvinal [7]
100 because opposite angles are equal. The angles in the triangle above add up to 80 so the last angle must equal 100. Since angle 1 is directly opposite to that angle, it also equals 100.

Given the equation 6x + 18 = 72: Part A: Write a short word problem about a purchase made to illustrate the equation. (6 points)
bulgar [2K]

Considering the linear function 6x + 18 = 72, it is found that:

A. The problem is: You made a number of services for $6, plus a base pay of $18, and earned $72. How many services you made?

B. The solution is: x = 9.

C. In the context of this problem, the solution means that you made 9 services.

<h3>What is a linear function?</h3>

The general format of a linear function is presented as follows:

y = mx + b.

In which the coefficients are:

  • m is the slope, representing  the variable amount, that is, by how much y changes when x is increased by one.
  • b is the y-intercept, which is the fixed amount.

In this problem, the equation is:

6x + 18 = 72.

From the given equation, considering the slope of 6 and the intercept of 18, the problem can be presented as follows:

You made a number of services for $6, plus a base pay of $18, and earned $72. How many services you made?

The solution is found isolating the variable x, as follows:

6x = 72 - 18

6x = 54

x = 54/6

x = 9.

The solution x = 9 represents the number of services that you made, in the context of this problem.

To borrow​ money, you pawn your guitar. Based on the value of the​ guitar, the pawnbroker loans you ​$960. One month​ later, you
Diano4ka-milaya [45]

The money was paid at an annual interest of 261.42%

Explanation:

  • The initial amount of the guitar when it was loaned was $960. After a month the guitar cost $1,170. This means that in one month the price went from $960 to $1,170.                                                                               Increase in cost = Difference between two costs = $1,170 - $960 = $210.
  • To convert this into a percent we divide the difference in value by the original price and multiply the answer with 100 to convert it into a percentage.                                                                                                      % increase in cost = difference between two costs / original cost                                                                                           % increase in cost = ($210 / $960) * 100 = 0.21785 * 100 = 21.785%
  • This 21.875% was the monthly interest that was paid. To convert it into annual interest rate we multiply it with the 12 months.
  • Annual interest rate = monthly interest rate * 12 = 21.785% * 12 = 261.42%. This means if the guitar was loaned for a year, you would have to pay $3469.44.
