Answer:
Solution
To solve the problem first we have simplify the improper fraction.
⇒ 33/4 ÷ 4 pounds.
= (4 × 3 + 3) /4 ÷ 4 pounds.
= 15/4 ÷ 4 pounds.
= 15/4 × 1/4 pounds.
= 15/16 pounds.
Now we know that, 1 pound = 16 ounces.
Therefore, 15/16 pounds .
= 15/16 × 16 ounces.
= 15/1
= 15
= 15 ounces.
Answer: 15 ounces.
X in less than or equal to 4.5. it is this because 32 is the least number of miles per gallon. 144/32=4.5.
Answer:
B. -19/25
Step-by-step explanation:
You are looking for an answer that is greater than -4/5 (which is equal to -0.80) but less than -3/4 (which is equal to -0.75). So, you can easily convert the fractions to decimals by dividing.
-33/50 = -0.66, which is greater than -0.75, so it can be eliminated.
-19/25 = -0.76, which fits our parameters, so it is the answer.
-19/20 = -0.95, which is less than -0.80, so it can be eliminated.
-7/10 = -0.70, which is greater than -0.75, so it can be eliminated.
Answer:



Step-by-step explanation:
Given




Required
The dimension that minimizes the cost
The volume is:

This gives:

Substitute 


Make H the subject


The surface area is:
Area = Area of Bottom + Area of Sides
So, we have:

The cost is:



Substitute:
and 



To minimize the cost, we differentiate

Then set to 0


Rewrite as:

Divide both sides by W

Rewrite as:

Solve for 


Take cube roots

Recall that:







Hence, the dimension that minimizes the cost is:
