Check the picture below.
now, we're making an assumption that, the two blue shaded region are equal in shape, and thus if that's so, that area above the 14 is 6 and below it is also 6, 14 + 6 + 6 = 26.
so hmm if we simply get the area of the trapezoid and subtract the area of the yellow triangle and the area of the cyan triangle, what's leftover is what we didn't subtract, namely the shaded region.

Ac and db are chords that intersect at point h. a circle is shown. chords a c and d b intersect at point h. the length of a h is 20 minus x, the length of h b is 12 minus x, the length of d h is x 4, and the length of h c is x. what is the length of line segment db? 4 units 8 units 16 units 20 units
Answers
The chords ac and db are intersecting chords, and the length of line segment db is 16 units
How to determine the length of segment db?The given parameters are:
ah = 20 - x
hb = 12 - x
dh = x + 4
hc = x
Start by calculating the value of x using the following intersection chord equation
ah * hc = dh * hb
So, we have:
(20 - x) * x = (x + 4) * (12 - x)
Solve for x
x = 4
The length of segment db is calculated using:
db = dh + hb
So, we have:
db = x + 4 + 12 - x
Substitute 4 for x
db = 4 + 4 + 12 - 4
Evaluate
db = 16
Hence, the length of line segment db is 16 units

In 2014 the population of Kenya was estimated to be 45,121,040 with a growth rate of 2.7%. Question 1 Use the exponential growth formula to write an equation that estimates the population y in terms of the time t. Enter your answer in the box. Then apply the exponential growth formula to estimate the population of Kenya in 2020. Round to the nearest whole number
Answers
Answer:
y = 45,121,040×1.027^t
Step-by-step explanation:
An exponential growth equation is generally of the form ...
value at time t = (initial value)(growth factor)^t
where the growth factor is the multiplier for a period equal to one time unit.
Here, the initial value (in 2014) is 45,121,040. The growth factor is given as 1.027 (2.7% added per year), and we can define t as the number of years after 2014. Then our equation is ...
y = 45,121,040×1.027^t . . . . where t = years after 2014

Find x and y.
Answers
(3y + 40) + (130 -2x) = 180 because the angles are supplementary
plug in x
3y + 40 + 130 - 2(65/3) = 180
so 3y = 95/3
therefore y = 95/6
x = -25
y = -13.33
Step-by-step explanation
To find x
(130 - 2x)° + 4x° = 180°
130 - 2x + 4x = 180
130 - 2x = 180
130 - 180 = 2x
x = -50 ÷ 2
x = -25 answer
To find y
(130 - 2x)° + (3y + 40)° = 180°
130 - 2x + 3y + 40 = 180
170 - 2x + 3y = 180
By putting the vaue of x in the equation
170 - 2(-25) + 3y = 180
170 + 50 + 3y = 180
3y = 180 - 170 - 50
y = -40 ÷ 3
y = -13.33 answer

Answer:
Answer would be B
Step-by-step explanation:
First, A doesnt make sense, since it isn't a ineqality.
C doesnt make sense because if 5 is subtracted form a number n, it is -2, not 2.
D doesnt work because 5 less a number (-5) is not 2, it is -2.
So B works, because the difference between n and 5 (n-5) is -2.

One week, kevin earned $492.00 at his job when he worked for 20 hours. if he is paid the same hourly wage, how much would he make the next week if he worked 3 hours?
Answers
Answer:
$73.80
Step-by-step explanation:
First we will find Kevin's hourly wage. We can do this by dividing his total pay by the number of hours he worked.
$492 / 20 hours = $24.60/hour
Now we can find how much he will make the next week.
$24.60/hour * 3 hours = $73.80.

Answers
If Rob receives $4,585.75 in annual dividends, the number of shares of Agram Imports that Rob owns is D. 441 shares.
What is a dividend?A dividend is the distribution of cash or stock that a company makes to its stockholders periodically.
Dividends are usually based on a dividend payout ratio, determined by the Board of Directors of the company.
Data and Calculations:Dowc Beverage Co. Agram Imports
Dividend per share $6.52 $5.15
Number of shares x x+ 86
Number of shares 355 (441 - 86) 441 (355 + 86)
Total dividend received $2,314.60 ($4,585.75 - $2,271.15)) $2,271.15
which is equivalent to $2,314.60 ($355 x $6.52)
Assuming total shares from Agram Imports to be 441, the total dividends will be $2,271.15 ($5.15 x 441), and, the dividend from Dowc Beverage Co. will be $2,314.60 and the number of shares will be 355 ($2,314.60/$6.52), which is 86 less than the shares in Agram Imports.
Thus, if Rob receives $4,585.75 in annual dividends, the number of shares of Agram Imports that Rob owns is D. 441 shares.
