You could set up a ratio given that it is a 5% solution (5% of the total, not 5% of water.
5/100 = x/473 You need to find out how much is vinegar. Cross multiply
5 * 473 = 100 x Find the number on the left.
2365 = 100 x Divide by 100
2365 / 100 = x
x = 23.65 mL of vinegar.
The water is found by subtraction
473 - 23.65 = 449.35 mL of water.
Answer:
35%/5 = 7 b=7 7 + 35x7= 966 / 21 = 46
Step-by-step explanation:
Answer: the value of the account after 6 years is $101559.96
Step-by-step explanation:
If $64,000 is invested in an IRA account, then
Principal = $64,000
So P = 64,000
The rate at which $64000 was compounded is 8%
So r = 8/100 = 0.08
If it is compounded once in a year, this means that it is compounded annually (and not semi annually, quarterly or others). So
n = 1
We want to determine the value of the account after 6 years, this means
time, t = 6
Applying the compound interest formula,
A = P(1 + r/n)^nt
A = amount after n number of years
A = 64000( 1 + 0.08/1)^1×6
A = 64000(1.08)^6
A= 64000×1.58687432294
A= 101559.956668416
Approximately $101559.96 to 2 decimal places
Answer:
14) 21.136505024965 m
15) 43.076759215619 km
Step-by-step explanation:
14)
let h be the height of the lighthouse:
tan(41.3) = 18.7/h
Then
h = 18.7÷tan(41.5)
= 21.136505024965 m
………………………………………
15)
90-71.4 =18.6
Let s be the distance that the plane flew
towards the south:
tan(90 - 71.4) = s/128
Then
tan(18.6) = s/128
Then
s = tan(18.6)×128
= 43.076759215619 km
A=p (1-r)^t
A future value?
P present value 28000
R rate of depreciation 0.0725
T time 5 years
A=28,000×(1−0.0725)^(5)
A=19,218.9 round 19219
