Help! Central Angles and arc measures

Mathematics
1 answer:
enot [183]1 year ago
6 0

Answer:

  x = 11

Step-by-step explanation:

The sum of arcs of a semicircle is 180°. That fact can be used with the given angle relations to find the value of x.

<h3>Setup</h3>

The measure of an arc is the same as the measure of the central angle it subtends.

  DC +CG +GF = 180

The angle bisector CH ensures that angles CHD and CHG are congruent. That means arcs CD and CG are congruent, and we have ...

  DC +DC +GF = 180 . . . . . . . . . use DC for CG

  2(7x -1) +(2x +6) = 180 . . . . . . . use the given expressions

<h3>Solution</h3>

This equation can be solved for x.

  16x +4 = 180 . . . . . . . . . . . . simplify

  16x = 176 . . . . . . . . . . . . subtract 4

  x = 11 . . . . . . . . . . . . . divide by 16

klasskru [66]

Around 6 hours (exact decimal would be 5.99865). I did this by multiplying 14.85*40 (getting 594). After that, I subtracted 594 from 727.65 (getting 133.65), then multiplying 14.85 by 1.5, getting 22.28, and then, I did 133.65/22.28, getting 5.99865, which I rounded to 6.

S_A_V [24]

Answer:

The question is not complete but from the flow of thought, the question seems to be about what your choice will be between option 1 and option 2.

The correct answer is

option 2

Step-by-step explanation:

The question is asking you to choose an option that pays more after 30 days. In other to determine the more beneficial option, we will compare both options and select the one that pays more. This is done as follows:

option 1: $60,000 per day, after 30 days =

60,000 × 30 = $1,800,000

option 2 = $5,368,709.12 after 30 days

From the total amounts after 30 days of the two options listed above, option 2 is higher than option 1 by $3,568,709. Therefore, option 2 is a better choice.

Your friend finds that the correlation between shoe size and iq is r = 1. 99. what should you say about these findings?
Gennadij [26K]

An error was made, correlation values can't be greater than 1.00.

The strength of the linear association between two variables is quantified by the correlation coefficient. The correlation coefficient always takes a value between -1 and 1. The 1 represents the perfect positive correlation and -1 represents the perfect negative correlation whereas the 0 represents the no correlation between two variables.

So, if the value of the correlation coefficient between shoe size and IQ is r = +1.99 then,

Analysts in some fields do not consider a correlation significant until the value is at least 0.8. However, a correlation coefficient with an absolute value of 0.9 or greater indicates a very strong relationship. 2.
