Answer:
59 degrees
Step-by-step explanation:
Inscibed angles in a circle encompass TWICE their value of arc degrees
2x = 118
x = 59 degrees
30×·15=4.50
then subtract 30 by 4.50 to get 25.50
.0825×30=2.475
now add 2.475+25.50+30= 57.975 round to 57.98
Answer:
1.60 (rounded)
Step-by-step explanation:
I haven't done this in a while but you'd use the compound interest formula a=p(1+r)^n where a=8300 p=5000 r=0.075 and solve for n
Y = mx + b
First equation 1 = m(4) + b, bring everything to one side m(4) + b - 1 = 0
Second equation 7 = m(5) + b, bring everything to one side m(5) + b - 7 = 0
Set them equal to each other,
m(4) + b - 1 = m(5) + b - 7
If you bring the b over to the left hand side it becomes
m(4) + b - b - 1 = m(5) - 7
m(4) - 1 = m(5) - 7
Solve for m
6 = m
Plug m = 6 into either equation from the beginning,
m(4) + b - 1 = 0
6(4) + b - 1 = 0
24 + b - 1 = 0
b = -23
Knowing m and b we can now make an equation
y = mx + b
y = 6x -23 Final answer
<span>Find the round trip distance:
4.95 km/hr * 48 min * 1 hr/60 min = 3.96 km
1.98 km each way
d = r*t
t = d/r = 1.98/4.5
t = 0.44 hrs upstream
t = 26.4 minutes upstream</span>
