100-10=90

450=90% of original find 100%
divide by 9
50=10%
times 10
500=100%
origianl price=$500 (this is the hack way that only works with nice numbers)

Answer: Original Price=$450


Step-by-step explanation:

Price post discount=$450

Discount=10%

Let the original price be x

Given x - 10% of x=450

x-\frac{10}{100}\times x

\frac{100x-10x}{100}=450

\frac{90x}{100}=450

x=\frac{100\times450}{90}

On solving

x=500$

The original price =500$

So how you do scientific notation is, however many places you move the decimal point to the left is the number that you put in the power. For example, Mercury's mass is 330,000,000,000,000,000,000,000. You move the decimal point 23 places to the left to get 3.3 x 10^23. ( ^ means power. The little number that is next to the 10)

Now according to the question, the mass of Jupiter is 5.8 x 10^3 multiplied by 3.3 x 10^23 (5,800 x 330,000,000,000,000,000,000,000).

The answer to part A is,
1,941,000,000,000,000,000,000,000,000

Then, 3.2 x 10^2(X)=5.8 x 10^3 x 3.3 x 10^23

I don't know if you know how to do algebra, but this is very simple to solve. All you do is divide bolth sides of the equation by 3.2 x 10^2 leaving X (Earths mass) on the left.

For the right side need to divide 320 by 1,941,000,000,000,000,000,000,000,000. This will be the answer to part B

Hopefully this was helpful enough for you to show your work. Good luck : )

4. A loan made on March 12 is due September 10 of the following year. Find the exact time for the loan in a non-leap year and a
saul85 [17]

Answer:

182 days

Step-by-step explanation:

Given:

Date on which loan is made = March 12

Due date of the loan = September 10

Now,

The months in between March and September and the number of days in the particular months are

Month                          Number of days

April                               30

May                                31

June                               30

July                                 31

August                            31

------------------------------------------

Total number of days =  153

also,

Number of days left in March after 12 are (31 - 12 ) = 19 days

and,

Number of days in September before the due date = 10 days

Hence, the total time for loan = 19 + 153 + 10 = 182 days

since the included months does not have the month of February. Therefore,

the time for both leap year and non-leap year will remain same.
