Answer:
25 milliliters
Step-by-step explanation:
Given:
volume of sample = 100 ml
Syrup present in sample = 6.55 g per 20 mL
Therefore in 100 mL, amount of syrup present = 
or
amount of syrup present in 100 mL sample = 32.75 grams
Now,
Specific gravity of the syrup = 1.31
also,
Specific gravity of the syrup = 
or
1.31 = 
or
Density of syrup = 1.31 g/mL
also,
Density = 
therefore,
1.31 = 
or
Volume of syrup in the sample = 
or
Volume of syrup in the sample = 25 milliliters
99=3/8g+2+12g+2
-4 -2 -2
95=3/8g+12g
95=12(3/8)g
(Divide both sides by 12(3/8))
2.96875=x
Or 3
Answer: the value of the car after 7 years is $11220
Step-by-step explanation:
The formula for determining depreciation is expressed as
A = P(1 - r)^t
Where
A represents the final value of the car after t years.
P represents the present value of the car.
r represents the rate of depreciation
t represents the number of years.
From the information given
P = 35000
r = 15% = 15/100 = 0.15
t = 7 years
Therefore,
A = 35000(1 - 0.15)^7
A = 35000(0.85)^7
A = 11220.198
Rounding up yo the nearest dollar, it becomes $11220
A lot of numbers and it really depends
