Answer:
20%
Step-by-step explanation:
Because 144 OUT OF the 180 seventh grade students attended, this would represent 144/180.
But since we are trying to solve how many did NOT attend the dance, you must subtract 144 from 180 which equals 36. So 36/180 did not attend the dance.
But to make it a percentage, you divide 36/180. Fraction and percentage are like buddies! That's why it is very simple to make a fraction into a percentage.
36/180 can be simplified to 1/5, which as a decimal, is 0.20.
0.20 is same as 20%, so this should be the students that did not attend the dance.
I hope this helps. If this is wrong, I truly apologize...

4. Your job as a carpenter pays $20/hour and you worked 40 hours last week. The taxes
withheld from your wages were $83 federal tax and $19 state tax. Your total check is
a. $698
b. $720
c. $810
d. $912
Answer:
698.00 (A)
Step-by-step explanation:
20.00x40=800.00
83.00+19.00=102.00
800.00-102.00=698.00
The total amount of the check will be $698. Then the correct option is A.
What is Algebra?The analysis of mathematical representations is algebra, and the handling of those symbols is logic.
Your job as a carpenter pays $20/hour and you worked 40 hours last week.
Then the amount that you earn in 40 hours will be
⇒ $20 x 40
⇒ $800
The taxes withheld from your wages were $83 federal tax and $19 state tax. Then the total amount of the check will be
⇒ $800 - $83 - $19
⇒ $800 - $102
⇒ $698
The total amount of the check will be $698. Then the correct option is A.

Which expression is equivalent to ( xy -6)2 for all values of x and y where the expression is defined?
Answer:
( x y -6)² = x² y² - 12 xy + 36
Step-by-step explanation:
Explanation:-
Given that the expression ( x y -6)²
Apply formula (a-b)² = a² -2ab + b²
( x y -6)² = (xy)² - 2 × xy× 6 + (6)²
= x² y² - 12 xy + 36
( x y -6)² = x² y² - 12 xy + 36

In the year 1984 the average American used to eat 55.7 pounds of chicken. This was 2.8 pounds more than the the year 1982 average. By what percent did chicken consumption increase from the year 1982 to the year 1984?
To solve this, we need to use the z statistic. The formula for z score is:
z = (x – u) / s
where x is sample value = less than 90, u is the sample mean = 90.6, s is the standard deviation = 17.2
z = (90 – 90.6) / 17.2
z = -0.035
From the standard distribution tables:
P (z = -0.035) = 0.4860
Therefore there is about 48.60 % chance that it will be less than 90 pounds
Answer:
I think it increased by 0.05.
Step-by-step explanation:
If you subtract 2.8 from 55.7 you'll get 52.9. So I would divide 55.9 by 52.9 and get 1.05. I then would subtract 1.0

Answer:
UT = 8
Step-by-step explanation:
From the picture, we can make the following equation...
5 + 2x - 6 = x + 6
By solving it we get
5 + 2x - 6 = x + 6
2x - 1 = x + 6
2x = x + 7
x = 7
Therefor if UT = 2x - 6, then UT is equal to...
2x - 6 = UT
2(7) - 6 = UT
14 - 6 = UT
8 = UT

7(y + 3) = 5y + 8
Answer:
-13/2
Step-by-step explanation:
7(y+3)=5y+8
7y+21=5y+8
7y-5y+21=8
2y+21=8
2y=8-21
2y=-13
y=-13/2
Answer:
y = -6.5
Step-by-step explanation:
simplify: 7y+21=5y+8
put like-terms together and simplify: 2y=-13
(like-terms: 7y-5y=8-21)
divide both sides by 2: y=-6.5
trigonometry problem
Answer: -3π/2
Step-by-step explanation:
The unit circle is tricky, but here are some things to know:
When measuring angles, you usually move in the counter-clockwise direction. If you are moving clockwise (like shown in your picture), the angle will be negative. The unit circle is typically measured in radians, not degrees- To convert from radians to degrees, multiply by 180/π
- To convert from degrees to radians, multiply by π/180
The whole unit circle measures 2π (360 degrees). This means that the positive x-axis can be referred to as 0 or 2π, the positive y-axis is referred to as π/2, the negative x-axis is referred to as π, and the negative y-axis is referred to as 3π/2.-If the angle is negative, switch the signs of the axis above.
The information above is all you need to answer the above question, but if you want/need anything else on the unit circle, just let me know.
Find the measure of this angle.
