Answer:
3.28 feet
Step-by-step explanation:
One meter equals to 3.28 feet.
The question isn't exactly clear what Gema wants to use her wire for, because "wrap one meter" isn't correct.
You wrap something around something else... and you can't wrap something around a meter. You can wrap around a square meter by doing the perimeter... but then you'd need more than meter to do the perimeter of a square meter (the perimeter can be around 4 meters).
So, assuming she has a length of 1 meter to cover, she would need 3.28 feet.
Answer: 40
-----------------------------------------------------------------------------
Notice how WI = 12 is one-third of IL = 36
So AM is going to be one-third of ML = 30 making AM = 10
AL = AM+ML = 10+30 = 40
AL = 40
Or a more formal way to do it is to use ratios
AL/ML = WL/IL
AL/ML = (WI+IL)/IL
AL/30 = (12+36)/36
AL/30 = 48/36
36*AL = 30*48
36*AL = 1440
AL = 1440/36
AL = 40
Either way we get the same answer
Answer:
B. 28
Step-by-step explanation:
Since (4x + 10) and 122 degrees are angles that are across from each other (vertical angles), they equal each other.
4x + 10 = 122
-10 -10
4x = 112
/4 /4
x = 28
The answer is the first one, (2)
Answer:
D.
Step-by-step explanation:
To tell whether the domains can include 0, all you need to do is find where x = 0, and whether the y-value is real.
h(x) = sqrt(2x^2 + 5x - 3)
= sqrt(0^2 + 5 * 0 - 3)
= sqrt(-3)
Since this includes the square root of a negative number, h(0) is an imaginary number. That means that we can eliminate choices A and B.
If you look at the graph of w(x), when x = 0, there is a real value for the y-value on the graph. But, if you think about it, if you have 0 workers, there is no way that you can still be producing wrenches. So, the domain cannot contain 0.
Your answer will be D.
Hope this helps!!
