Answer:
12 hours
Step-by-step explanation:
First to solve this problem, let's look at what we are dealing with here. It says that Ali made $126 for 9 hours of work.
Let's set that up into a fraction so it's easier to look at.
money/time = 126/9
Now that we have that set up let's look at our other piece of information.
It asks for how many hours would Ali have to work in order to make $168 so let's figure that out.
In order to find out the number of hours, let's first find our unit rate which can be simply found by dividing our given money/time.
126/9 = 14.
This means that for every 1 hour, there will be 14 dollars earned.
Now that we know that, let's look for how many hours it take to earn $168.
In order to do that simply see how many times 14 goes into 168 (division) and that way you can see how many hours it will take to earn $168.
168/14 = 12 hours.
Answer:
C
Step-by-step explanation:
The FOIL method is a handy way to remember how to multiply two binomials.
It stands for "First, Outer, Inner, Last" and works as
- multiplying the First terms,
- multiplying the Outer terms,
- multiplying the Inner terms,
- multiplying the Last terms,
- finding the sum of all products.
In your case it looks like
![(x^2-2)(5x+1)=x^2\cdot 5x+x^2\cdot 1+(-2)\cdot 5x+(-2)\cdot 1.](https://tex.z-dn.net/?f=%28x%5E2-2%29%285x%2B1%29%3Dx%5E2%5Ccdot%205x%2Bx%5E2%5Ccdot%201%2B%28-2%29%5Ccdot%205x%2B%28-2%29%5Ccdot%201.)
For this specific problem, the statement “every chord is a diameter” is
false. The correct answer between all the choices given is the third
choice or letter C. I am hoping that this answer has satisfied your query and
it will be able to help you in your endeavor, and if you would like, feel free
