Graphite is made up of layers of graphene. Each layer of graphene is about 200 picometers, or 200 x 10^-12 meters thick. How many layers of graphene are there in a 1.6mm thick piece of graphite? Express your answer in scientific notation.
Answers
Answer:8x10^-8
Step-by-step explanation:I am brainlyest
Number of layers of graphene are there in a 1.6mm thick piece of graphite is,
⇒ 8 × 10⁶
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;
Graphite is made up of layers of graphene. Each layer of graphene is about 200 picometers, or 200 x 10⁻¹² meters thick.
Hence, Number of layers of graphene are there in a 1.6mm thick piece of graphite is,
⇒ 0.0016 m / 200 x 10⁻¹² m / layer
⇒ 8 × 10⁶
Thus, Number of layers of graphene are there in a 1.6mm thick piece of graphite is,
⇒ 8 × 10⁶

Maggie is buying a jacket. The expression shown represents the sales tax on the jacket price, j.
0.08j
Write an expression in terms of j to represent the total amount that Maggie spends on the jacket, including tax.
Answers
Answer: 1.08j
Step-by-step explanation: if we add 8% of something to itself, we now have 108%, right
1.08j
I’m not 100% sure tho
The expression represents the total amount that Maggie spends on the jacket, including tax is 1.08j.
What is Percentage?A percentage is a way to describe a part of a whole. such as the fraction 1/4 can be described as 0.25 which is equal to 25%.
To convert a fraction to a percentage, convert the fraction to decimal form and then multiply by 100 with the '%' symbol.
As it is given that the cost of the jacket is j, while the tax on the jacket is 0.08j. therefore, the total cost of the jacket can be written as the sum of the cost of the jacket and the tax on the jacket.
Thus, the total cost of the jacket = Cost of jacket + Tax on the jacket
= j + 0.08j
= 1.08j
Hence, the expression represents the total amount that Maggie spends on the jacket, including tax is 1.08j.

Answers
Answer: 60 miles/hour
Step-by-step explanation:
Departure time: 5:30
Arrival time: 8:30
Distance = 180 miles
Total time it took to travel = 3 hours.
Recap: Distance = (Speed) × (Time)
Plug the number into the formula:
180miles = (speed) × 3hours
Solve for speed by dividing both sides by 3 hours:
180miles/3hours = Speed
Simplify:
60 miles/hour = Speed

Step-by-step explanation:
First find the total of the entire straight line. We know that a straight line is 180 degrees.
Since we already have 2 given numbers, add them.
51+31=82
Since we already have 82 degrees, subtract it with 180.
180-82=98.
So, y = 98
