Answer: 5.4 x 10^8 on Khan Academy
The scientific notation of the expression is,
⇒ 5.4 × 10⁸
What is Scientific notation?Scientific notation is a way of writing a very large or very small numbers. For example; 230,000,000 can be written in scientific notation as 2.3 x 10⁸.
Given that;
The expression is,
⇒ 1.4 x 10⁹ - 8.6 x 10⁸
Now, Simplify the expression as;
⇒ 1.4 x 10⁹ - 8.6 x 10⁸
⇒ 14 x 10⁸ - 8.6 x 10⁸
⇒ (14 - 8.6) × 10⁸
⇒ 5.4 × 10⁸

The area of a triangle is related to the base and height of the triangle by the formula a = bh/2. Rewrite this equation with b solved in terms of a and h.
Answer: b = 2a/h
Step-by-step explanation:
a = bh/2
multiply each side by 2
2a = bh
divide each side by h
2a/h = b
Answer:
b = 2a/h
The area of a triangle is related to the base and height of the triangle by the formula a = bh/2
The price of a Honda Civic is $26,750. You can finance this by paying $3500 down and $455 per month for 60 months. Determine the total finance charge. A. $3500 B. 3750 C. $4050 D. $5200
Answer:
Step-by-step explanation:
455 per month for 60 months = 60 * 455 = 27,300
Plus amount of down payment = 27,300 + 3,500 = 30,800
Finance charge = 30,800-26,750 = 4,050

The density of oxygen is 0.001332 gram per cubic meter. Represent 0.001332 in scientific notation.
Answer:
1.332 × 10-3
Step-by-step explanation:
you move the decimal point to the right until there's only one digit on the left side of it. the exponent is 3 because that's the number of places you moved the decimal point, and it's negative because you moved it to the right. if you move the decimal to the left it is positive, to the right is negative :)
By basic calculation We can represent 0.001332 in scientific notation as [tex]1.332\times 10^{-3}[/tex]
What is scientific notation?Scientific notation is a way of expressing numbers big numbers in short form with approximate values.
Given number is 0.001332
we can write 0.001332 as
1332/1000000
or we can write it as
1.332/1000
and now we can write it in Scientific notation form as
[tex]\frac{1.332}{10^3}\\\\1.332\times 10^{-3}[/tex]
By basic calculation We can represent 0.001332 in scientific notation as [tex]1.332\times 10^{-3}[/tex]

20 POINTS! The following graph shows the amount of money Jonah earns when he babysits for the family who lives next door. Based on the graph, which of the following statements are true? Select ALL that apply.
When Jonah babysits one hour, he earns $7.50.
The equation e = 4 h can be used to describe this situation.
Jonah earns $20 to babysit for 5 hours.
The number of hours Jonah works depends on how much he earns.
Answer:
The equation e = 4 h can be used to describe this situation.
Jonah earns $20 to babysit for 5 hours.
Step-by-step explanation:
When Jonah babysits one hour, he earns $7.50.
looking at the graph we see at 1 hour he earns 4 dollars false
The equation e = 4 h can be used to describe this situation.
The slope is 4 so y = 4x e = 4h would also work true
Jonah earns $20 to babysit for 5 hours.
Using our equation from above
e = 4*5 = 20 true
The number of hours Jonah works depends on how much he earns.
This would be false
The dependent variable is on the y axis. The amount he earns depends on how much he works
