Answer:

The atomic weight (or atomic mass) of Vanadium is 50.9415 which means that a "mole" of Vanadium atoms (6.02 x 10^23 atoms) will have a mass of 50.9415 grams. So, 214.1 grams of Vanadium would have

(214.1 / 50.9415) * (6.02 x 10^23) = 2.530 x 10^24 atoms

Number of rides marine can go on ?

saul85 [17]

Answer:

Check step by step explanation

Step-by-step explanation:

a) Let x represent the amount of rides she takes, the 6 and 2.5 represent the amount of money required to enter

A(x) = 1.5x + 6

B(x) = 2x + 2.5

b) You can find this by making the 2 equations equal to each other and solving for x

1.5x + 6 = 2x + 2.5

3.5 = .5x

7 = x

7 rides make them equal cost

c) Plug in 5 for each of the equations and find out which one is cheaper

A(5) = 1.5 * 5 + 6

A(5) = $13.50

B(5) = 2 * 5 + 2.5

B(5) = $12.50

Carnival B is cheaper

Which number sentence is true?

Alexxx [7]

Answer:

The answer is B

Step-by-step explanation:

Because A is incorrect because the -8.9 is in absolute value which mean it will be an 8.9 which is greater than 5.6

C is Incorrect because - 5.6 is not greater than the absolute value of -8.9 which is 8.9, as you can see is greater than -5.6

D is incorrect because the absolute value of 5.6 is still 5.6 and the absolute value of - 8.9 is 8.9 which is greater that 5.6

<h2>B is correct because the absolute value of -5.6 is 5.6 which makes it less than the absolute value of -8.9 because the absolute value is 8.9 which is greater than 5.6 .</h2>
