Let us start with something we know is true.
5 > 3
That reads as 5 is greater than 3. Anyone will tell you that that is a true statement.
But what happens when you multiply this result by - 10
5 * -10 > 3 * - 10
- 50 > - 30 is that true? If you are not sure, think it terms of money. Which would you rather be
owing 50 dollars to some or owing 30 dollars to someone? Of course if you are careful with money you would likely say neither. But this is math so you have to choose.
You likely would have to say you would want to owe 30 dollars. That makes - 30 larger than - 50. So a true statement has now become a false one. Check with me if you don't understand. I'd like to know if you accept my explanation.
2 1/2 / 4 4/5
the answer is 0.2 or 1/5
hope this helps
The first thing we are going to assume for this case is that the tree and the post are located in the same place.
From that place, both cast a shadow in the same direction.
We then have two similar triangles.
Therefore, we have the following relationship:
From here, we clear the value of x.
We have then:
Rewriting:
Answer:
the tree is 30 feet tall
Answer:
The answer is 20,358,520
Step-by-step explanation:
Selecting 6 numbers from a collection of 52 numbers regardless of order involves a combination.
Note: if regards was taken into order of selection, this would be a permutation.
Hence, the different 6 number selections out of 52 is
52C6 = 52! / [6!*(52-6)!]
= 52!/(6!*46!)
= 20,358,520
Answer:
for example, if f(x)= x^2 + 3
and they gave write f(5)= 5^2 +3
=25+3=28
