Answer:

C: $747

Step-by-step explanation:

To find the amount after compound interest, we use the formula:

a =  {p(1 +  \frac{n}{100} })^{t}

Where a is the result amount, p is the amount he deposited, n being the interest rate and t being the amount of years. Substitute these variables with the amounts in the question to get

7200 {(1 +  \frac{2.5}{100} })^{4}

Input that into a calculator to get $7947.45281...

Next, subtract the original amount of 7200 and you will result with

747.45281 which is 747 corrected to the nearest dollar.

A can do a piece of work in 4 hours and B can do it in 6 hours. How much time would they take working together to finish the wor
Kipish [7]

Answer:

2.4 hours

Step-by-step explanation:

Let total work = X

Rate of work done = X ÷ time

Rate of A = X/4

Rate of B = X/6

If they work together, rate is the sum of their individual rates, i.e.

X/4 + X/6

= (3X + 2X)/12 (taking LCM)

=5X/12

Rate = X/time

5X/12 = X/time

time = X÷(5X/12)

time = X × 12/(5X)

time = 2.4 hours

Shortcut:

Product of individual times/sum of individual times

= (4×6)/(4+6)

=24/10

=2.4 hours

xz_007 [3.2K]

Answer:

Transitive Property

Step-by-step explanation:

Since X is the midpoint, it bisects the points RS. If MX=XS, and RS is the same as XS, then they are the same. This also follows the Transitive propety  (if a=b and b=c, then a=c)
