A² + b² = c²
~~~~~~~~
a² + 3² = 4²
a² + 9 = 16
a² = 7
a² = 2.6 ft
Try this solution:
rule: Distance=speed * time, where Distance=10216 (mi); t=8 (h) and speed=slower_jet + faster_jet (mi/h);
note, that faster_jet=slower_jet+65 (mi/h). Using these:
(slower_jet+65)*8=10216;
slower_jet=(10216-520)/16;
slower_jet=606 (mi/h);
faster_jet=606+65=671 (mi/h).
answer: <u>606 & 671</u>
The answer is A sheila because she buying
Time taken for the amount deposited to grow to $5000 will be found as follows:
A=P(1+r/100*n)^nt
where:
A=amount
P=principle
r=rate
n=number of terms
t=time
thus plugging in our values we have:
5000=3587.39=(1+4.2/200)^2t
solving for t we have:
1.393771=1.021^2t
2t=ln1.393771/ln1.021
2t=16.111
t=8.055685 years~8 years
X = 3
6x + 4 = 22
6x = 18 (subtract 4 from both sides)
x = 3 (divide 6 from both sides)
