express 0.0003 in Scientific notation by counting decimal places
Answers
Answer:
When we write numbers in scientific notation, we must put the first non-zero digit ahead of the decimal. In this case, the decimal would be behind the 3. Because we moved the decimal places four times to the right, our exponent will be 4. Thus,
3.00 x 10⁻⁴
we can express 0.0003 as 3 × 10⁻⁴ in scientific notation.
To express 0.0003 in scientific notation, we count the number of decimal places from the original number until we have a single non-zero digit before the decimal point. In this case, we have four decimal places before the non-zero digit (3).
Thus, we can express 0.0003 as 3 × 10⁻⁴ in scientific notation. The negative exponent (-4) indicates that we move the decimal point four places to the left to obtain the original value.
In summary, by counting the decimal places, we can express 0.0003 as 3 × 10⁻⁴ in scientific notation.

Which ordered pair is a solution of the equation?
y = -3x-4.
Answers
Answer:
B. Only (-3,5)
Step-by-step explanation:
1. Plug in the x values from the answer choices and see if it gives you the y-value in the answer choices.
A. y=-3(-2) - 4
= 6 - 4
y = 2
The ordered pair for answer A is (-2,4) where the y-value is 4. Well, when you plugged in -2 for x you got 2, not 4. So A can't be the right answer.
B. y=-3(-3) - 4
= 9- 4
y = 5
The y-value in this ordered pair (-3,5) is indeed 5, so this answer holds true.
Therefore, the answer is B because it is the only ordered pair that has the correct solution.
Answer: Only (-3,5)

What is simple interest?Simple interest is the concept that is used in many companies such as banking, finance, automobile, and so on.
A customer has a credit card that charges 18% simple interest every year.
The customer saves by paying off a credit card debt of $5,000 at the end of 1 year instead of at the end of 3 years.
Interest for three years will be
[tex]\rm A_3 = \dfrac{PRT}{100}\\\\\\A_3= \dfrac{5000*18*3}{100}\\\\\\A_3= 2700[/tex]
Interest for one year will be
[tex]\rm A_1 = \dfrac{PRT}{100}\\\\\\A_1= \dfrac{5000*18*1}{100}\\\\\\A_1= 900[/tex]
The saved amount will be
A = A₃ - A₁
A = 2700 - 900
A = 1800
