Mass × gravitational energy × height
= gravitational potential energy
= joules
by interrelating the formula,
mass (unknown) × 10 × 629.9
= 2033.76
unknown = 0.32??
this is my working ^ but I'm not positive that it's 100% correct!
X= # of people who attended the movie
Numerator= # of people under 30
Denominator= total # of people
60/100 = 1200/x
Then we cross multiply
60x = 120000
x = 2,000
Final answer= 2,000 people attended the theater
Answer: i think the answer is 1 6/35
Step-by-step explanation:
Answer:
b = 30 / a
which agrees with the third expression in the list of possible options
Step-by-step explanation:
When we say that a and b vary inversely, that means that in mathematical form:
b = k / a where "k" is the so called "constant of proportionality". In order to write the function that models this inverse variation, we need to find the value of "k". We do such by using the information they provide (b = 5/2 when a = 12):
5/2 = k / 12
Then, solving for "k":
5 * 12 / 2 = k
60 / 2 = k
k = 30
Then we can now write the function that models this inverse variation:
b = k / a
b = 30 / a
