Javier works in a photo lab and needs to make a reduced copy of a photograph that is 8 inches long. The customer wants the copy

to have a length of 4.5 inches. Each time he presses the reduce button on the copier, the copy is reduced by 12%. Javier and his boss had an argument, because Javier claimed that pressing the button 5 times would be enough to fulfill the customer's request. His boss said that pressing the button 5 times would result in a length less than the desired 4.5 inches. Which of the following conclusions can be made?

To find the percentage that the customer wants reduced, we use this equation:
8n = 4.5
n = 4.5/8
n = 0.5626
Because javier believes that reducing 12% 5 times would work, he is assuming that:
56.26 - 60 = 0
This is not the case.
Javier's boss is correct.

Pythagorean theorem, I'm trying to fix my grade for school so I get my phone back
Harrizon [31]

If you would illustrate the problem, you will be able to formulate a triangle with the measurement of the hypotenuse (distance between the two shops) to be missing. Using the Pythagorean Theorem, the formula to compute for the hypotenuse is:

c = √a^2 + b^2

c = √(20)^2 + (13.5)^2

c = √400 + 182.25

c = √582.25

c = 24.13 km

Therefore, the distance between the two shops is approximately 24.13 km.

How do I answer this question
soldi70 [24.7K]

The answer is C. 2.

This is because the part that is inside of the parentheses is equal to 4. Multiplying the fractions in the numerator is equal to 4^\frac{3}{2}.

\frac{4^\frac{3}{2}}{4^\frac{1}{2}}=4., using the exponential rule 3/2-1/2=2/2 or 1. 4^1=4.

Now, we reduced the fraction, so all that is left is (4)^\frac{1}{2}. This is equal to 2.

So your answer is 2.

I hope this helps :)

The liters in the tank when it is filled to a height of 3.70 is  5,580 liters

The liters that needs to be added to 100% capacity is 480 liters

<h3>What is the volume?</h3>

A right circular cone is a three dimensional object has a flat circular base that tapers to a vertex. The volume of a right circular cone is the amount of space in the right circular cone.

Volume of a cone = 1/3(πr²h)

Where:

  • π = pi = 3.14
  • r = radius
  • h = height

Volume of the right circular cone when its filled to a height of 3.70 = 1/3 x 3.14 x 3.70 x 1.20² = 5.58 m³

5.58 x 1000 = 5,580 liters

Volume of the right circular cone when it is full =  1/3 x 3.14 x 4 x 1.20² = 6.03  m³

6.03 x 1000 = 6030 liters

Liters that needs to be added to 100% capacity =  6030 liters - 5,580 liters  = 480 liters
