Estimate 63.730+ 32.73 by first rounding each number to the nearest whole number​
Shalnov [3]

Answer:

97

Step-by-step explanation:

Round each number to the nearest whole number (the digit directly left to the decimal point.) Note that if the digit to the right of the decimal point is 5 or greater, round up; if it is 4 or lower, round down:

63.730 rounded to the nearest one is 64.

32.73 rounded to the nearest one is 33.

Add:

64 + 33 = 97

97 is your answer.

7. Find the amount of money accumulated if you invest $10,000 at 3% interest compounded continuously for 2 years. Round your
IrinaK [193]

Answer:

$10618.37

Step-by-step explanation:

Use the formula for compound interest:

P(t) = P_0e^(rt)

You can look the formula up online to find what each variable represents.

First, our principal amount (P) is 10,000. Our interest rate (r) is 3% and our time (t) is 2. Substitute these into the equations in each variables' place. The equation will look like this:

P(t) = 10,000e^(0.03x2)

P(t) = 10,000e^(0.06)

Note that e is approximately 2.7183 .

Using your calculator, now simply find P(t).

You should get 10618.36972 as your answer. Round that to the nearest cent to get $10618.37 .

multiply the probabilities together:

1/4 x 4/11 x 1/2 = 1/22
