Answer:

£13,110.49

Step-by-step explanation:

The formula for Compound interest is calculated as =

Compound Interest = Total Amount (A) - Principal (P)

Since we have already been given the principal in the question as £200,000

The next step would be to find and calculated the Total amount(A) that would be saved after 4 years using the formula below:

(A) = P( 1 + r/n) ^nt

Where A = Total amount

P = Principal which means the amount you are investing in savings

r = interest rate

n = number of times the interest is compounded( it could be daily, weekly,monthly or annually).

t = number of time periods elapsed.

From the question, for Claire's savings investment, we were given the following values:

P(Principal) = £200 000

r(interest rate) = 1.6% = 0.016

n = for Claire this is annually i.e per year = 1

t = number of time periods elapsed = 4 years

The total amount been saved after 4 years is calculated as:

A = P( 1 + r/n) ^ nt

A = £200,000( 1 + 0.016/1)¹× ⁴

A =  £200,000(1.016)⁴

A =  £213,110.48991

Approximately, A = £ 213,110.49

The total amount been saved after 4 years =  £ 213,110.49

From the question above, we were asked to calculate the total amount of interest Claire would get after 4 years. And we can do that using this formula:

Total Amount = Principal + Compound interest

Therefore, Compound Interest = Total amount - Principal

Where: Total amount = £213,110.49

Principal = £200,000

Compound interest = £213,110.49 - £200,000

Compound interest = £13,110.49

Therefore, the total amount of interest Claire will get at the end of 4 years =  £13,110.49

So sorry about the error. The error has been corrected above already. Thank you.

in 2 h, kelly laid new floor tile over 1/5 of the room. when she was joined by annette, the rest of the work was completed in 3h
jeyben [28]

Answer: Annette will take 6 hours to do the entire job alone.

Step-by-step explanation:

Given: Time taken by Kelly to do \dfrac{1}{5} of job = 2 hours

i.e. Time for complete job done alone by Kelly =5\times2=10\ hours

Rest of work = 1-\dfrac{1}{5}=\dfrac{4}{5} of the job

\dfrac{4}{5}  of the complete job done by both Kelly and Annette in 3 hours

Time would be taken by then to do entire job together = 3\times\dfrac{5}{4}=3.75\ hours

Let t be the time taken by Annette to do job alone.

Then, as per situation

\dfrac{1}{3.75}=\dfrac{1}{10}+\dfrac{1}{t}\\\\\Rightarrow\ \dfrac{1}{t}=\dfrac{1}{3.75}-\dfrac{1}{10}\\\\\Rightarrow\ \dfrac{1}{t}=\dfrac{4}{15}-\dfrac{1}{10}\\\\\Rightarrow\ \dfrac{1}{t}=\dfrac{1}{6}\\\\\Rightarrow\ t=6

hence, Annette will take 6 hours to do the entire job alone.

How many quarts of pure antifreeze must be added to 8 quarts of a 40% antifreeze solution to obtain a 60% antifreeze solution?
Vinvika [58]

Answer:

we have 8 quarts of 40% antifreeze,

according to the britain equivalent, 1 quart = 1.13L

so, we have 8 * 1.13L  = 9.04 L

out of the 9.04 L, 40% is antifreeze

amount of antifreeze = 0.4 * 9.04 = 3.616 L

moles of antifreeze present = 3.616/22.4 = 0.16 moles

moles of antifreeze in 60% solution = 0.6 * v/22.4 = 0.027 * v          

<em>(where v is the volume of final solution)</em>

molarity of initial solution = 0.16/9.04 = 0.018 M

molarity of final solution = 0.027*v/v = 0.027 M

m1*v1  = m2*v2

0.018 * 9.04 = 0.027 * v

v = 0.018 * 9.04/0.027

v = 6.026 L

amount if antifreeze in the final solution = 6.026 * 0.027 =  

0.163 Moles of antifreeze

amount in L = 0.163 * 22.4 = 3.65 L

amount in quarts  = 3.65/1.13 = 3.23 quarts
