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

Answer:
Step-by-step explanation:
Each package holds 24 so you would use the equation n = 24p
which means the number of lightbulbs = 24 times the number of packages
so 1 package = 24
3 packages = 72
10 packages = 240

A. 17/12
B. 1 & 12/5
C. 15/12
D. 17/3
Answer:
A) 17/12
Step-by-step explanation:

Answer:
A 17/12
Step-by-step explanation:
because 4 and 1/4 is equal to 17/4 and you need to divide that by 3 which can also be written as
17/4 × 1/3 = 17/12

Please help me explain as well. AD is 48. I will give brainliest.
Answer:
The area of the rectangle is 48
Step-by-step explanation:
We know that AE is 6 and ED is 8, since it forms a triangle, use the Pythagorean theorem to find AD, which is one side of the rectangle.
The Pythagorean theorem says that a^2 + b^2 = c^2.
a is AE, b is ED, and c is AD, so 6^2 + 8^2 = c^2, 36 + 64 = c^2, 100 = c^2, 10 = c, so AD is 10
The area of the triangle is half of AE times ED, so 1/2(6)(8) = 1/2(48) = 24, the area of the triangle is 24.
Since the area of a triangle is 1/2 of the base times the height, we can figure out the height:
A = 1/2bh, 24 = 1/2(10)h, 24 = 5h, 4.8 = h, so the height of the triangle (and rectangle) is 4.8.
The height of the triangle is also the height of the rectangle:
The area of the rectangle is 4.8*10 = 48

A worker can load 4 pallets in 30 minutes. At that rate, how many pallets can he load in 4 hours?
Answer:
32
Step-by-step explanation:
1 hour = 60 minutes
Thus, 30 minutes if half an hour.
The worker can load 4 pallets every 30 minutes.
30*2=60
4*2=8
So the worker can load 8 pallets every 60 minutes, or every hour.
8*4=32
So, a worker can load 32 pallets in 4 hours.
BONUS: The worker can load 1 pallet every 7.5 minute
