Well if one week is 7 days, and there are 42 days left, then 42 / 7 = 6 more weeks.

Hope this helps!

To answer this question, you will need to divide 42 by 7. There are 7 days in the week and 42 days left. Once divided, you will be left with the number 6. With that being said, there are 6 weeks left of school.

suter [353]

Answer:Amount = 10,002.21

Step-by-step explanation:4 x 5 = 20 times

2.-

Principal = 5,000

Interest rate per yr = 3%

Compounded times per yr = 4

Time in years = 5

The formula is amt = p*(1 + r/n) ^ (n*t),

thus

Amount = 5,805.92

3.-

If Time in years = 23.2

then

Amount = 10,002.56

4.-

Principal = 5,000.00

Interest rate per yr = 5.82%

Compounded times per yr = 4

Time in years = 12

Answer:

As there is one math problem over there.

Lets see the question first:

It says that "A hair dryer is rated $1200\ W$ ,if you use the dryer for $0.25\ h$ .How much electric energy do you use ?"

Final answer = Electic energy $=0.3\ kW\ h$

Step-by-step explanation:

Electrical Energy $E=Power \times time$ .

The total amount of electrical energy used depends on the total power used by the electrical device and the total time they are used for.

So we have been given the power of the hair dryer $=1200\ W =\frac{1200}{1000}=1.2\ kW$

Now the time it has been use for $=0.25\ hrs$

To calculate electric energy we will multiply both the terms.

Electric energy $=0.12 \times 0.25 =0.3\ kW\ h$

So electric energy used for the hairdryer is = $0.3\ kW\ h$
