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

Step-by-step explanation:
A. Rate of change (or slope) is $50
The initial tutoring fee starts out at $1200 in 2005
How do you know? Each year the cost goes up $50
2005 = $1200
2006 = $1250
2007 = $1300
2008 = $1350
B. y=50x+b
If there are 27 students in the class and they have to form as many groups of 4 as possible, you can calculate this using the following step:
27 / 4 = 6.75 = 6 3/4
Result: 27 students can form 6 groups of 4 students and 3 students have to form their own group.
Answer:
hypotenuse is 34
Step-by-step explanation:
a²+b²=c²
16²+30²=c²
256+900=1156
√1156 =34
hypotenuse =34
Let's solve the equation step-by-step
Step 1) Simplify both sides of the equation
3+ j/11 = 2
1/11j+3=2
Step 2) Subtract 3 from both sides
1/11j + 3 - 3 = 2 - 3
1/11j = -1
Step 3) Multiply both sides by 11
11 x (1/11j) = (11) x (-1)
j = -11
Answer is.. J = -11
