If it’s easy then why not do it yourself?
It goes largest exponent first, then go down until there’s no variable or exponent.
Answer is:

Step-by-step explanation:
3 3/4=15/4 3 1/4=13/4 turn the mixed fractions into improper fractions
(15/4)(3)(13/4)=36.5625ft³ this is the volume of the shipping box
(1/4)(1/4)(1/4)=1/64ft³ this is the volume of the fish food box
36.5625/(1/64) divide it to find out how much fish boxes can fit
36.5625×64 flip the fraction and multiply
2340
Answer:
The value of y given the values of x and z in the question is -734.85
Step-by-step explanation:
This is a joint variation question.
First, we are made to know that y varies jointly as x and z.
The equation for this can be written as;
y = k * x * z
Where k is the constant of proportionality.
Let’s calculate k first.
117 = k * (-3) * (-11)
33k = 117
K = 117/33 = 3.55
Now, we proceed to get what y is when x = -9 and z = 23
Let’s plug these values into the initial equation written.
y = k * x * z
We use the value of k calculated above;
y = 3.55 * (-9) * (23) = -734.85
