What is the area of a desktop that is 2 1/2 feet by 5 feet?
Elden [556K]

The area of the desktop is 12. 5 feet square

<h3>How to determine the area</h3>

The formula for area of a rectangle;

Area = length × width

Length = 2. 5 feet

Width = 5 feet

Area = 2. 5 × 5

Area = 12. 5 feet square

Thus, the area of the desktop is 12. 5 feet square

How do you evaluate logarithms? Explain using an example or mathematical evidence to support your answer.
kenny6666 [7]

Answer: Explanation below.

Step-by-step explanation:

First of all you need to know how to convert a logarithm into an exponential expression. The property is:

log_Bx=n

This is the same as: B^n=x

Example 1:

log_99=

We are trying to find what to raise 9 to, in order to get a result of 9.

9^x=9

When you have same bases, you equal exponents.

x=1

Therefore; log_99=1

Example 2:

log_232=

2^x=32

In this case, we have to make sure both sides have the same base. 32 can have a base of 2 if expressed as: 2^5 which is 2*2*2*2*2

Rewriting this example we have;

2^x=2^5

Since we have the same base, we equal exponents.

x=5

Therefore; log_232=5

Example 3:

log_3729=

3^x=729

729 can have a base of 3 if expressed as: 3^6

3^x=3^6

x=6

Write a real world problem that involves classifying a quadrilateral. Then solve the problem
Sever21 [200]
We have a lot of encounters where we are forced to apply our knowledge in geometry, plane figures and especially quadrilaterals. First, we need to know the types of quadrilaterals, it differences, and the corresponding equations. One real world problem is when we are asked to make a kite for our younger sibling and he or she specified the dimensions.

What is the best classification for -24?
lara31 [8.8K]

Answer: Integer

Step-by-step explanation: I would classify -24 as an integer for the best classification. Although -24 is a rational number, we tend to think of negative numbers as integers. Although -24 would be a rational number too, there are many rational numbers in the negatives that have decimals other than 0 so the best classification for it would be an integer.
