Answer:
72-63=9
9/72=13%
13% IS .13 SO TENTH IS .1
I AM NOT SURE ABOUT THE TENTH
Step-by-step explanation:
1a) so for this problem, I took what they gave you, 637.5 and divided it by .75 and got 850
so .75 * 850 = the gallons, so just take the number of hours and multiply it by 850 to get your gallons
0.25 x 850 = 212.5
1.5 x 850 = 1,275
2.5 x 850 = 2,125
1b) the unit rate is 850
1c) 5.5 x 850 = 4,675 gallons
1d) So 850 gallons can be filled in an hour, you only need 100 gallons
850/100 = 17/2 (simplified)
17 gallons/hour 60 minutes
------------------------- x ---------------------
2 gallons 1 hour
the gallons cancel out and the hours cancel out which leaves us with:
17 x 60 = 1,020 / 2 = 510
510 minutes
2) I don't know how to do two sorry
Answer:
C. 40-4x-12x^2
Step-by-step explanation:
very simple
? – (20 – 4x – 5x2) = 20 – 7x2, so ? = 20 – 7x2 + (20 – 4x – 5x2)
? = 20 – 7x2 + (20 – 4x – 5x2)=20-7x²+20-4x-5x²=40-12x²-4x
Answer:
True
Step-by-step explanation:
It is still a traditional bank. The online option is there for your convenience, but doesn't make the bank all online. Hope this helped!
The annual returns will be calculated as follows:
a] Here we use the formula:
A=p(1+r/100)^n
A=future amount
p=principle
r=returns
n=time
We are given:
A=500, p=400, t=1
Plugging the values in the formula we obtain:
500=400(1+r)^1
simplifying and solving for r:
1.25=1+r
thus
r=1.25-1
r=0.25~25%
b] Using the formula above:
A=p(1+r/100)^n
A=2500+100=2600, p=2000, n=1 year
plugging the values in the equation we obtain:
2600=2000(1+r)^1
simplifying and solving for r we obtain:
2600/2000=1+r
1.3=1+r
hence
r=1.3-1
r=0.3~30%
