64 v^2 + 18 = 34 subtract 18 from both sides of the eqaution
64 v^2 = 16 divide both sides by 64
v^2 = 16/64 take sq root
v = + 4/8 or -4/8 (+- 1/2)
Michael age = x
Sarah age = x-3
Eli age = 2 (x-3)
difference between eli and sarah = 2(x-3)- (x-3) = 2x-6-x+3= x-3 when x= 12 x-3 = 9 yrs difference
Assuming a constant rate of birth across all of the days of the year
jun = 30 days
july=31 days
aug = 31 days
92 days/365.25 days/yr = .25188= 25.188% chance
I will assume you will need to get 75% of the questions correct to pass
.75 x 12 = 9 correctly answered = pass (barely)
.3 hr x 60 min/hr = 18 minutes
Assuming she assembles correctly and at the rate of 110 toys/hr
$.09/toy x 110 toys/hr x 8 hrs/day = $ 79.20/day (8 hour shift)
Typo..... Asinus found the square root of 13 x 10^-14 instead of 15 x 10^-14
Here is the graph of the equation (an easy way to visualize the range)
range is y>=-6.25
8(t+2)+3t+3=16+2
8t+16+3t+3=18
11t+19=18
11t=-1
t=-1/11
You can set this up as a simple ratio:
7280/520000 = x/650000
x= 9100 tax
