Answer:
<u>2.256 x 10 to the power of 25</u>
Step-by-step explanation:
There are 3.76 x 10 to the power of 22 atoms in 1 gram of oxygen
So, there are x atoms in 600 grams of oxygen
Using the ratio and proportional
So, the number of atoms = 600 * 3.76 x 10 to the power of 22 =
So, the answer in scientific notation as A.BCD x 10 to the power of E
Will be <u>2.256 x 10 to the power of 25</u>
Answer:
Option C
A = 390 
Step-by-step explanation:
The image shows a figure composed of a rectangle and a triangle.
We know that the area of a rectangle is:
Ar = length * width
Then, using the data shown in the image, we have to:
Ar = 20(15) = 300
Then, the area of a triangle is:
So:
Finally the area of the figure is:
Answer:
don't know don't know don't know don't know don't know don't know don't know
Step-by-step explanation:
don't know don't know don't know don't know don't know don't know don't know don't know
Just equate both to each other and you get:
<span>x + 1 = y = 4x + 5
Leave out the y, and you get
</span>x + 1 = 4x + 5
That was I believe your first option.
You can now work out x:
-3x = 4 => x = -4/3
Answer:
B
Step-by-step explanation:
B) because both result in the equation 8 x = 400, which simplifies to x = 50
