Answer:
8.9
Step-by-step explanation:
We know that 81 = 9², so √80 will be slightly less than 9. We can get a pretty good estimate by averaging 9 with 80/9. That result is 8.94, so about 8.9.

Atomic number tells you the number of ______________ contained in the nucleus of an atom. Which is always equal to the number of _____________ in an atom.
Answers
Answer:
The atomic number is equal to the number of protons in an atom
The atomic number tells you the number of protons in one atom of an element. It also tells you the number of electrons in a neutral atom of that element. The atomic number gives the “identity “of an element as well as its location on the Periodic Table.
Step-by-step explanation:
The atomic number is the number of protons in an atom of an element. For example, krypton's atomic number is 36. This tells us that an atom of krypton has 36 protons in its nucleus.
The atomic number tells you the number of protons contained in the nucleus of an atom. Which is always equal to the number of electrons in an atom.
What is an atom?An atom is the smallest possible unit of a chemical element.
There are protons and neutrons in the nucleus of an atom, and electrons outside the nucleus.
The atomic number indicates the number of protons or the number of electrons.
Therefore, Atomic number tells you the number of protons contained in the nucleus of an atom. Which is always equal to the number of electrons in an atom.

. Bartholomew Jackson is paid $10.56 an hour to knit dog sweaters. He gets paid 1.5 times his normal wages for overtime (over 40 hours per week). If he works 55.5 hours in one week, how much money does he earn
Answers
Answer:
$667.92
Step-by-step explanation:
Use the equation (p*1.5)*o=t
the variable p is equal to his hourly pay.
the variable o is equal to hours worked overtime.
the variable t is equal to the total amount of money they will make.
As for the 1.5, this is the way overtime is always calculated, at 1.5 times the rate of your hourly wage.
Back to the question:
the variable p is replaced by his hourly pay, $10.56.
the variable o is replaced by the amount of hours he worked overtime. Now, this part is a bit trickier because the question is designed to confuse you. If his overtime only counts if he works over 40 hours a week, then you need to subtract the 40 from his total amount of hours worked. You should get 15.5 because 55.5-40=15.5. Thus, variable o=15.5.
Lastly, you have to calculate it.
Plug in the variables to get:
($10.56*1.5)*15.5= $245.52
DON'T STOP HERE!!!
Since the question asks for how much he has earned for the week, you have to add this onto his normal salary. This part is easy, just multiply the 40 hours by his pay. So,
40*$10.56= $422.40.
Finally, add the overtime ($245.52) to his normal pay ($422.40).
$422.40+$245.52= $667.92

They are the same just change positions
Answer:
qp
Step-by-step explanation:
pq = p * q
In multiplication like this, the order doesn't matter:
5 * 3 = 15

9 * 2 = 18
Thus,
pq = p * q = q * p = qp

If the measures of the angles in the following triangle were listed in increasing order, which measure would be second? (2x+24) ° (4x+43) ° (x^2+1) °
Answers
Answer:
x²+1 is the second
Step-by-step explanation:
2x+24=40°
4x+43=75°
x²+1=65°
(2x+24) + (4x +43) + (x²+1)=180
x²+6x+68=180
x1=-14
x2=8
since there's no negative angle, we'll use x=8

What is the absolute value of -10? How do you know this? please heeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeelp please
Answers
Answer:
The absolute value of -10 is -10
Step-by-step explanation:
Absolute value describes the distance of a number on the number line from 0 without considering which direction from zero the number lies. The absolute value of a number is never negative.
...
Absolute Value (For example)
|6| = 6 means the absolute value of 6 is 6.
Answer:
The absolute value of -10 is just 10.
Step-by-step explanation:
Anything that comes out of the absolute value brackets, which look like this |-10|, becomes positive.
For example the absolute value of -|-10| is -10. Why? Well, because the absolute value of the -10 inside is 10, but then you have to add the negative that is outside that bracket so the answer is -10.
If the number inside the bracket is positive, is comes out the way it is, positive.

If (x-2) is a factor of x^3+kx^2 +12x-8 then k=?
Answers
Answer:
k = - 6
Step-by-step explanation:
Since (x - 2) is a factor then x = 2 is a root
Substitute x = 2 into the polynomial and equate to zero, that is
2³ + k(2)² + 12(2) - 8 = 0
8 + 4k + 24 - 8 = 0
4k + 24 = 0 ( subtract 24 from both sides )
4k = - 24 ( divide both sides by 4 )
k = - 6
