16. 72236.03
17. 2.87
18. 2.36
19. 9.29
20. 1.65
The exponential growth formula is as follows
$y=a(1+r)^{x}$ :
a is initial value
($27,225 17. gallon of gas, $1.08 18. dozen eggs, $0.89 19. movie admission, $3.50 20. mcdonalds hamburger, $0.62)
r is rate of increase (0.05)
x is time (2008-1988 = 20 years)
to solve plug in values for each one.
 $y=27225(1+0.05)^{20} = 72236.03$

$1.08(1+0.05)^{20} = 2.87$

$.89(1+0.05)^{20} = 2.36$

$3.50(1+0.05)^{20} = 9.29$

$.62(1+0.05)^{20} = 1.65$

sp2606 [1]

Sum measure interior angle = (n-2)180 ; n is the no.of sides

=(3-2)180

= 180°

53+59+x = 180

111+x = 180

x = 180-111

x = 69°

Angle B is 69°

Yolanda wants to complete the 50-mile biathlon in 5 hours. she gets her jogging rate up 6 miles/hour and her biking rate up to 1

melamori03 [73]

Let x be the number of hours she jogs, and y be the number of hours she bikes.
The total time would then be x + y = 5
The total distance (based on the given speeds) would be 6x + 12y = 50
Multiply the first equation by 6 to get 6x + 6y = 30
Subtract this from the second equation to get 6y = 20
y = 10/3 or 3 1/3
Substitute this value back into the first equation to get x = 5/3 or 1 2/3
Therefore, Yolanda will have to jog 1 2/3 hours and bike 3 1/3 hours.
