Answer:
$468.09
Step-by-step explanation:
first we must calculate the expected future value of the engine overhaul:
($390 x 10%) + ($570 x 30%) + ($750 x 50%) + ($790 x 10%) = $39 + $171 + $375 + $79 = $664
now we must determine the present value of $664 using a 6% interest rate:
PV = FV / (1 + r)⁶ = $664 / 1.06⁶ = $468.09
Answer: The y intercept.
Step-by-step explanation:
Using the form y = mx +b, m represents the slope and b is the y intercept. In the equation y = 3/4x + 2, the slope (m) = 3/4 and the y intercept (b) = 2

first brand quantity is x
2nd brand quantity is y
x+y=30
0.3x+0.55y=0.35(30) or 0.3x+0.55y=10.5
solve for x and y
multiply first equation by -0.3
-0.3x-0.3y=-9
add to 2nd equation
0.3x-0.3y=-9
<u>0.3x+0.55y=10.5 +</u>
0x+0.25y=1.5
0.25y=1.5
divide both sides by 0.25
y=6
sub back
x+y=30
x+6=30
x=24
you need 24 gallons of the first brand and 6 gallons of the 2nd brand
Answer: 705m
Explanation:
Using cosine rule:
c²= a²+b²-2abcosC
Substituting:
c²=750²+650²-2(750)(650)cos60
c=√Ans
c= 705.336799..
=705m (nearest metre)
