Answer:
No, it is not a square
Step-by-step explanation:
If one wall is 19", that would mean the wall perpendicular to this wall is also 19" (in fact all of the walls would be 19"!) If this was a square, then the diagonal we draw at 20.62" would serve as the hypotenuse of a right triangle. One wall would serve as a leg, and another wall as another leg. If this is a square, then the Pythagorean's Theorem would be satisfied when we plug in the 2 wall measures for a and b, and the diagonal for c:
We need to see if this is a true statement. If the left side equals the right side, then the 2 legs of the right triangle are the same length, and the room, then is a square.
361 + 361 = 425.1844
Is this true? Does 722 = 425.1844? Definitely not. That means that the room is not a square.

2. B
Step-by-step explanation:
<u>Question 1:</u>
We can get Avon's earnings using the equation
Where W is his earnings
HR is the regular hours (40 hours in this case)
V is overtime hours (hours over 40, 45.5 - 40 = 5.5 hours)
B is bonus (no bonus)
T is tips ( $100 tips, given)
and R is the rate (which is $5 per hour)
<em>Substituting the given info into the equation, we get:</em>
<em></em>
<em>So avon's earnings are $341.25</em>
<em>Answer choice D is right.</em>
<u>Question 2:</u>
The other employee needs to work hours @ $15 per hour to equate or surpass $428. So we can set up the equation shown below and solve for x:
Rounded to 1 decimal place, this is about 28.5 hours
Answer choice B is right.
Answer:
Step-by-step explanation:
The given expression is
First, we need to factor each denominator
So, the least common factor (LCF) is , because they are the factors that repeats.
Now, we diviide the LCF by each denominator, to then multiply it by each numerator.
Then, we factor the numerator, to do so, we need to find two numbers which product is 10 and which sum is 7.
Therefore, the expression is equivalent to
