Answer:
The correct option is B. two oxygen atoms
Step-by-step explanation:
The molecular formula for carbon dioxide is given by :
Here, the alphabet C stands for Carbon and the alphabet O stands for Oxygen.
And the prefixes of each of these words represents the number of atoms present of the corresponding element in one molecule of carbon dioxide.
So, The prefix of the first word that is C is 1
⇒ One molecule of carbon dioxide contains one atom of Carbon.
The prefix of the second word that is O is 2
⇒ One molecule of carbon dioxide contains 2 atoms of Oxygen.
Therefore, The correct option is B. two oxygen atoms
Answer:
x = 1/64
Step-by-step explanation:
2x = 1/32
Divide both sides by 2.
Simplify, and you will get 1/64.
Answer:
Hi there!
Your answer is:
The smaller integer is -6
The larger integer is -5
Step-by-step explanation:
Two consecutive integers:
x, x+1
Product= multiply
(x) × (x+1) = x^2 - 6
x^2 + x= x^2 -6
-x^2
x= -6
Plug back in
First integer (smaller):
-6
Second integer (larger):
-6+1
-5
<u>Check</u><u> </u><u>your </u><u>work</u><u>!</u>
(-6) × (-6+1)
(-6)× (-5)
30 = (-6)^2 -6
30 = 36-6
30= 30 ✓✓✓✓
That's how we determine that <em>this </em><em>is</em><em> </em><em>the</em><em> </em><em>corr</em><em>ect</em><em> </em><em>answe</em><em>r</em>
Hopefully this helps
Answer:
x = √5 + 4 , -√5 + 4
Step-by-step explanation:
3(x - 4)^2 = 15
/3 /3 (divide both sides by 3)
----------------------
(x - 4)^2 = 5
(x−4)^2⋅1/2 = ±√5 (take square root of both sides)
x - 4 = ±√5 (add 4 on both sides)
+ +4
-----------------
x = √5 + 4 , x = -√5 + 4
