Answer:

x = 14.5

Step-by-step explanation:

The diagonals of a rhombus are at right angle to each other, then

∠ BOA = 90° , so

6x + 3 = 90 ( subtract 3 from both sides )

6x = 87 ( divide both sides by 6 )

x = 14.5

What is the sum of measurements of the interior angles of a 12-gon?​
Olin [163]

Answer:

1800

Step-by-step explanation:

Given in the question a polygon of 12 sides

Formula to calculate sum of interior angles of 12-gon is

<h3> (n – 2)180</h3>

where n is the number of sides

which in this case = 12

plug values in the formula above

(12 - 2)180

12*180 - 180(2)

2160 - 360

1800

Sum of measurements of the interior angles of a 12sided polygon is 1800

You are graphing y &lt; 2x + 1. What type of line do you use and where do you shade?
bazaltina [42]
Since there isn't a line under the < sign, this means that we used a dotted or dashed line. The dotted or dashed line indicates that we do NOT include the boundary as part of the solution set. 

Since y is isolated and we have a less than sign, this means we shade below the dashed/dotted boundary line. Specifically, the boundary line is the graph of y = 2x+1. This boundary line goes through (0,1) and (1,3). Again, points on this boundary line are NOT part of the solution set. 

So in summary we have:
A dashed or dotted boundary line
The shaded region is below the dashed/dotted boundary line.

Carlos and Mike work part time as salespeople for an electronics store. Carlos earns $7.25 per hour plus a $10 bonus. Mike earns
galina1969 [7]

Carlos and Mike earn same amount for 10 hours of part time work

<em><u>Solution:</u></em>

Let "x" be the number of hours worked by Carlos and mike

Given that,

<em><u>Carlos earns $7.25 per hour plus a $10 bonus</u></em>

Thus, total amount earned by Carlos for "x" hours is given by:

total earned = 7.25(number of hours) + $ 10

total earned = 7.25x + 10 ----- eqn 1

<em><u>Mike earns $7.75 per hour plus a $5 bonus</u></em>

Thus, total amount earned by Mike for "x" hours is given by:

total earned = 7.75(number of hours) + $ 5

total earned = 7.75x + 5 ------- eqn 2

To find number of hours, they earn same amount, equate eqn 1 and eqn 2

7.25x + 10 = 7.75x + 5

7.75x - 7.25x = 10 - 5

0.5x = 5

x = 10

Thus for 10 hours, they earn the same amount
