Answer:
$ 6.30
Step-by-step explanation:
A = P + I where
P (principal) = $ 6.00
I (interest) = $ 0.30
A = P(1 + r/n)nt
Answer:
20
Step-by-step explanation:
32/8 = 4
4 x 5 = 20

The original number is 7 i think.
10(x^2) = 70x
10x^2 - 70x = 0
x^2 -7x =0
Δ= b^2 -4ac
where c doesnt exist=0
Δ= 49
-b ± √Δ /2a
7 ± √49 /2
7±7/2
x is either 14/2= 7
or 1/2, which doesnt work.
Lets see:
10(7^2) = 70•7
10•49 = 490
and that is right.
i hope my logic is correct.
Answer:
Probability that there will be a seat available for every passenger who shows up is 50/50 or 49/50
Step-by-step explanation:
Since it is known that 5percent of people who make reservations would not show up.
Therefore 5% of 52 sold ticket is
5/100 x 52 = 2.6
That is 2 or 3 people who make reservations would not show up.
Which means 52 - 2 or 52 - 3 people would show up
50 or 49 people would show up
Since the flight can hold just 50 people
The probability that everyone that shows up would have a seat is therefore =
50/ 50 or 49/50
The proportion would be 1/3 and x/9. Cross multiplication creates 3x=9. Divide both sided by three, and there are 3 trombones in the orchestra.
