There are 3.76 x 10 to the power of 22 atoms in 1 gram of oxygen. How many atoms are there in 600 grams of oxygen? Write your an

tatiyna

Answer:

2.256 x 10 to the power of 25

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 =

$= 6*10^2 * 3.76 * 10^{22}\\=6*3.76 * 10^2*10^{22}\\=22.56 * 10^{24}\\=2.256 * 10 * 10^{24}\\=2.256 * 10^{25}$

So, the answer in scientific notation as A.BCD x 10 to the power of E

Will be 2.256 x 10 to the power of 25

-32>-5+9z Solve for x.

Darya [45]

Answer:

I do not know how it wants the answer, but it is -4.1 repeating.

I am guessing you meant solve for z too? If there are multiple choice I can help choose the right one.

Step-by-step explanation:

-32>5+9z

subtract 5 from both sides

-37>+9z

then divide 9 from both sides

-4.1111 repeating > z

Answer:

Midpoint is (0, -4)

Step-by-step explanation:

x-coordinate of midpoint = (-7 + 7)/2 = 0/2 = 0

y-coordinate of midpoint = (3 - 11)/2 = -8/2 = -4

Midpoint is (0, -4)

A manufacturer of skis offered chain discounts of 10/5/4 to many of its customers. Joe Jones ordered skis that had a total list

kati45 [8]

First,
149,500 * .10 = 14,950
149,500 - 14,950 = 134,550

then,
134,550 * .05 = 6727.50
134,550 - 6727 = 127,822.55
127,822.50 * .04 = 5112.90

trade discount = 14950 + 6727.50 + 5112.90
26790.40

hope this help
