How to convert numbers or decimals to scientific notation?

In scientific notation all numbers are written in the form of m×10n (m times ten raised to the power of n), where the exponent n is an integer, and the coefficient m is any real number, called the significand or mantissa. If the number is negative then a minus sign precedes m (as in ordinary decimal notation).

The answer to this question please.
Sunny_sXe [5.5K]

Answer:

Part A) y=1,100x + 4,500

Part B) 14,400

Step-by-step explanation:

Part A)

There is a base fee of $4,500, meaning that the line begins at y=4500 (i.e. The y-intercept is [0,4500], so 'b' in y=mx+b is 4,500). There is a $1,100 hourly rate, which is proportional to the value of x, the amount of hours filmed. Therefore, 'm' in y=mx+b is $1,100.

Thus, the final equation looks like:

y= 1,100x + 4,500

Part B)

x=9

y=1,100x+4,500

y=1,100(9)+4,500

y=9,900+4,500

y=14,400

Find the total amount of money​ (maturity value) that the borrower will pay back on a loan of ​$1 comma 760 at 13 and one half %
bagirrra123 [75]

Answer:

The borrower will pay back $4,136.

Step-by-step explanation:

This is a simple interest problem.

The simple interest formula is given by:

E = P*I*t

In which E are the earnings, P is the principal(the initial amount of money), I is the interest rate(yearly, as a decimal) and t is the time.

After t years, the total amount of money is:

T = E + P.

In this question:

Loan amount of 1760, so P = 1760

Interest rate of 13 and one half, so 13.5%. This means that I = 0.135.

10 years, so t = 10

Interest on the Loan:

E = P*I*t = 1760*0.135*10 = 2376

Total amount:

T = E + P = 2376 + 1760 = 4136

The borrower will pay back $4,136.

10,000,000+10,000,000
makvit [3.9K]

Answer:

20,000,000

Step-by-step explanation:

An easy way of looking at this is just adding the non-zero digits, which in this case would be 1 and 1. After we do that, we just add the remaining amount of zeros that we did not sum:

1 + 1 = 2

Now we add 7 zeros:

20,000,000

Hope it helped,
