Answer:
7.1 cm
Step-by-step explanation:
Let s represent the side length of the square. The Pythagorean theorem tells you the relationship to the diagonal length is ...
(10 cm)² = s² +s² . . . . the sum of the squares of the legs is the square of the hypotenuse
100 cm² = 2s² . . . . . . simplify
50 cm² = s² . . . . . . . . divide by 2
√(50) cm = s ≈ 7.1 cm . . . . . take the square root
The length of a side of the square to the nearest tenth is 7.1 cm.
Let's start with 14, shall we? Alright, so we know that positive and negative numbers are both on opposite sides of zero- negatives on the left, positives on the right. We see that we have a positive and negative. That lets us know that we have these two values on opposite sides. As for one, we see that it's (going to assume it's negative, as that's what it looks like. If not, do the same thing on the other side.) 5/8, we can only do fourths here, it seems, because there are four intervals between the numbers. Here's where the beauty of equivalent fractions comes in. 5/8 actually equals 2.5/4 if you divide the top and bottom by 2. Now it should be easy to graph it. A little after 1, and then in between 2 and three. Hope this helps.
Answer:
The answer is A
Step-by-step explanation:
Answer: { x | 5 < x ≤ 100 } OR { x ∈ ℝ | 5 < x ≤ 100 }
Step-by-step explanation:
{ x | 5 < x ≤ 100 }
This means:
"The set of all x's, such that x is greater than 5 and less than or equal to 100"
Another acceptable way to write this is
{ x ∈ ℝ | 5 < x ≤ 100 }
"x ∈ ℝ" simply means x is an element of all real numbers
