The answer is D.
This is because all of the equations are equivalent to __ x 9, because you have to solve the brackets (which are all the same) first.
Answer: 1/3
Explanation: don’t know how to explain
Answer:
Step-by-step explanation:
When dividing fractions, you just need to remember that all you need to do is get the inverse of the divisor and multipy.
So for the problem
5 = divident
3/4 = divisor
So we get the inverse of 3/4 which is 4/3 and then multiply.
Look above to see the process.
Answer:
Period =
The ferris wheel will complete one round in 40 seconds.
Step-by-step explanation:
We are given the function representing the height of the wheel by,
where t = time in minutes.
Now, we know that if a function f(x) has period P, then a×f(bx+c)+d will have the period .
Since, the function has period , thus the function h will have period i.e. .
Therefore, the period of this function is .
Now, since the period is minutes i.e 40 seconds.
Hence, we get that the ferris wheel will complete one round in 40 seconds.
12p + 7 > 139
subtract 7 from both sides
12 p > 132
divide both sides by 12
p > 11
