Answer:
See below.
Step-by-step explanation:
Squaring a number means to multiply the number by itself.
For example, 3^2 means 3 * 3.
8^2 means 8 * 8.
(-6)^2 means (-6) * (-6).
In each case above, you see that the number that is squared is multiplied by itself.
In this case, (-4.5)^2, squaring the number -4.5, means multiply the number -4.5 by the number -4.5
(-4.5)^2 = (-4.5) * (-4.5)
Now we need to actually multiply -4.5 by -4.5
When you multiply a negative number by a negative number, the result is positive, so the product of -4.5 and -4.5 is a positive number. To find that number, you multiply 4.5 by 4.5
4.5 * 4.5 = 20.25
Therefore, (-4.5)^2 = 20.25
90÷5=18 which means she makes $18 every hour.
Answer= $18
Answer:
can u be more specific so i can properly help u
Explanation:
pls explain and i will edit my answer
Here the denominators are quadratics , so we need to factorise them first
1/(x²-5x) +3/(x²+2x-35)
factorising x²-5x ,
here GCF is x, so taking x out we have
x(x-5)
factorising x²+2x-35 using AC method,
we find factors of -35 that add up to give 2
(x-5)(x+7)
Since we have x-5 common in both denominators, so lcd of the rational expression will be product of x(x-5)(x+7)
lcd is x(x-5)(x+7)
1. The problem gives the following information: <span>Ashley said she drank 1/2 pints and Claire said she drank 0.7 pints.
2. Therefore, to solve this problem you must follow the proccedure that is shown below:
3. You must sum the amount of water that Ashley and Claire drank before the practice. Then, you have:
1/2 pints=0.5 pints (Ashley)
0.7 pints (Claire)
x=0.5 pints+0.7 pints
x=1.2 pints
</span><span>
How many pints of water did Ashley and Claire drink combined?
</span><span>
The answer is: 1.2 pints or 1 1/5 pints
