Basically, the unit rate is 1.99/18 or 0.110.
If we round 1.99 to 2.00, we instead get 0.111~
Answer:
a = =36
Step-by-step explanation:
a + 6 = -30
make a on its own
a = -30 - 6
a = =36
Answer:
Step-by-step explanation:
According to the question, the correct graph is D.
It's not A because, the ball is thrown after some pause and the ball doesn't roll on the roof, falls immediately.
It's not B or C because the ball goes up after reaching the roof but should fall down.
Answer:
Current monthly payment on their existing mortgage would be $1158.66
Step-by-step explanation:
Total cash value = $160,000
Down payment = 10% of 160,000
Down Payment = $16,000
Balance amount = 160,000 - 16,000 = $144,000
Monthly payment formula:
where,
PV is present value of home, PV=$144,000
r is rate per period , 
n is number of period, n=30x12 = 360
Monthly payment would be same for 30 years.
Thus, Current monthly payment on their existing mortgage would be $1158.66
Answer:
10 hours
Step-by-step explanation:
(150/x) + 1.5 + (450/(x+15)) = 600/x
Multiply through by x(x + 15):
150(x + 15) + 1.5x(x + 15) + 450x = 600(x + 15)
150x + 2250 + 1.5x^2 + 22.5x + 450x = 600x + 9000
150x + 2250 + 1.5x^2 + 22.5x + 450x - 600x - 9000 = 0
1.5x^2 + 22.5x - 6750 = 0
x = (-22.5 +/- sqrt(22.5^2 - 4(1.5)(-6750))) / (2*1.5)
x = (-22.5 +/- sqrt(506.25 + 40500)) / 3
x = (-22.5 +/- sqrt(41006.25)) / 3
x = (-22.5 +/- 202.5) / 3
x = 180/3 or -225/3
x = 60 or -75
But a negative number doesn't make sense, so therefore x = 60, so the journey took 600/60 = 10 hours.
