Ella has 0.5 lbs of sugar. How much water should she add to make the following concentrations? Tell Ella how much syrup she will
shusha [124]
Concentration = [ (mass of sugar)/(mass of solution) ] * 100

=> mass of solution = mass of sugar * 100 / concentration

1) concentration 20%

mass of sugar = 0.5 lbs

=> mass of solution = mass of sugar * 100 / concentration = 0.5 lbs * 100 / 20

mass of solution = 2,5 lbs

mass of water = mass of solution - mass of sugar = 2.5 lbs - 0.5 lbs = 2.0 lbs

Answer: she must add 2.0 lbs of water and will obtain 2.5 lbs of syrup

2) concentration 25%

Follow the same procedure.

mass of solution = 0.5 lbs * 100 / 25 =

mass of solution = 2.0 lbs

mass of water = 2.0 lbs - 0.5 lbs = 1.5lbs

Answer: she has to add 1.5 lbs of water and will obtain 2.0 lbs of syrup

3) Same procedure

mass of solution = mass of sugar * 100 / concentration = 0.5 lbs * 100 / 1.5

mass of solution = 33.33 lbs

mass of water = 33.33 lbs - 0.5 lbs = 32.83 lbs

Answer: she has to add 32.83 lbs of water and will obtain 32.83 lbs of syrup

12345 [234]

Answer:

The interval 52% to 58% is based on a procedure that includes the true population value 95% of the time.

Step-by-step explanation:

x% confidence interval:

A confidence interval is built from a sample, has bounds a and b, and has a confidence level of x%. It means that we are x% confident that the population mean is between a and b.

95% confidence

We are 95% sure that the interval contains the true mean/proportion, and thus, the correct option is:

The interval 52% to 58% is based on a procedure that includes the true population value 95% of the time.

In what time will the simple interest on ra640 amount to RS 192 at 15 percentage per year​
Paha777 [63]

Answer:

2 years

Step-by-step explanation:

Simple Interest formula is given as:

I = P × R × T

P = 640

I = 192

r = 15% = 0.15

Hence, to find time we use the formula

T = I/P × R

T = 192/640 × 0.15

T = 192/96

T = 2 years

Therefore, it will take 2 years .
