1) A
2)D
3)D
4) Dunno
Here's the reason why I chose the answers as well.
1) When you have a debit card you are spending your OWN money. Therefor it's taken from the money if you have in your bank account.
2)Credit Cards are usually used when you don't have the cash at hand but have to pay it back.
3)The lower the credit score the worst it is.
C. is not a function since all the F9x) numbers are identical
In the balanced reaction
2 Fe + O₂ → 2 FeO
2 moles of iron (Fe) react with 1 mole of molecular oxygen (O₂) to produce 2 moles of iron oxide (FeO). The ratio of Fe to FeO is 1-to-1, so if one starts with 42.4 mol of Fe, one will end up with the same amount of FeO, 42.4 mol.
Look up the molar mass of Fe and O:
• Fe = 55.845 g/mol
• O = 15.999 g/mol
Then the molar mass of FeO is approximately 71.835 g/mol, and so the mass of 42.4 mol of FeO is
(42.4 mol) × (71.835 g/mol) ≈ 3050 g
Answer:
9
Step-by-step explanation:
The table is given below
We can see that the table represents a linear function since by checking its slope.
Using:
- Points (-2,15) and (1,6)
- Points (1,6) and (2,3)
Therefore, the values represent a linear function.
A linear equation is of the form y=mx+b
Therefore:
y=-3x+b
Using the points (7,-12)
Therefore, the y-intercept of the function, represented by the table of values is 9.
I believe the answer is 34.
Explanation:
I used the equation a^2 + b^2 = c^2
10 = a
24 = b
Plug it in.
10^2 + 24^2 = c^2
Get rid of the ^2
10 + 24 = 34
