<span>Answer:
a million) d/154 = 14/40 4 bypass multiply: 44d = 2156 d = 40 9 2) i will apply ^ to signify exponents, because of the fact superscript numbers do no longer artwork nicely at right here. c is continuous and represents the ratio of v to d^3 the dating is, subsequently: v = cd^3 3) enable w = wages for 5 adult adult males w/5 = $fifty two.08/3 bypass multiply: 3w = $260.40 w = $86.80 4) enable x = value of a 9-minute call x/9 = $0.ninety/6 bypass multiply: 6x = $8.10 x = $a million.35 5) i'm no longer completely confident what's being asked for in this one, yet i'm vulnerable to circulate with: P/a million = V/ok or P:a million = V:ok</span>
The question clearly states that "v varies directly as
the cube of d" means that for some constant c,
v = c d^3 [where ^ specifies the 3 is an exponent]
so c = v / (d^3)
If Vicki works 19 hours per week att $17.30 per hour, then her weekly savings is
(17.30)(19) = $328.70
So, if she needs to save at least 4 000, then she it will take her (4000/328.70) which is approximately 12.17 weeks. That means she has to save for at least 13<span> weeks. </span>
