In a water molecule<span>, the </span>oxygen<span> atom and </span>hydrogen<span> atoms share electrons in covalent bonds, but the sharing isn't equal. ... The unequal sharing of electrons gives the </span>water molecule<span> a little bit of a negative charge near its </span>oxygen<span> atom and a slight positive charge near its </span>hydrogen<span> atoms.</span>
Answer:
I'm fairly positive the answer is 90 degrees.
<span>here we can use Pythogoras' theorem.
in right angled triangles the square of the hypotenuse is equal to the sum of the squares of the other 2 sides.
hypotenuse is 19 cm. One side is 13 cm and we need to find the length of the third side.
19</span>²<span> = 13</span>²<span> + X</span>²<span>
X - length of the third side
361 = 169 + X</span>²<span>
X</span>²<span> = 361 - 169
X</span>²<span> = 192
X = 13.85 the length of third side rounded off to the nearest tenth is 13.9 cm</span>
Answer:
x = -12.5
Step-by-step explanation:
Solve : -2x - 10 =15
-2x - 10 = 15
-2x = 15 + 10
-2x = 25
x = -25/2
x = -12.5
Answer:
2
Step-by-step explanation:
this is because the inequality sign says greater than OR equal too, this would make the line solid, and since it's greater, all the values above that line would be included in the inequality
