B
Step-by-step explanation:
there will be 10 students in 4 groups
2c–8°, 3c–14°, and c+15°
solve for c
Answer:
Simplifying
c + -2 = 3c + 14
Reorder the terms:
-2 + c = 3c + 14
Reorder the terms:
-2 + c = 14 + 3c
Solving
-2 + c = 14 + 3c
Solving for variable 'c'.
Move all terms containing c to the left, all other terms to the right.
Add '-3c' to each side of the equation.
-2 + c + -3c = 14 + 3c + -3c
Combine like terms: c + -3c = -2c
-2 + -2c = 14 + 3c + -3c
Combine like terms: 3c + -3c = 0
-2 + -2c = 14 + 0
-2 + -2c = 14
Add '2' to each side of the equation.
-2 + 2 + -2c = 14 + 2
Combine like terms: -2 + 2 = 0
0 + -2c = 14 + 2
-2c = 14 + 2
Combine like terms: 14 + 2 = 16
-2c = 16
Divide each side by '-2'.
c = -8
Simplifying
c = -8

Use Quadratic equation to solve
a2 -4a - 4 = 0
Answer:
a = 2 ± 2[tex]\sqrt{2}[/tex]
Step-by-step explanation:
a = 1
b = -4
c = -4
x = (-b ± [tex]\sqrt{b^2 - 4ac}[/tex]) / 2a
x = (-(-4) ± [tex]\sqrt{(-4)^2-4(1)(-4)}[/tex]) / 2(1)
x = (4 ± [tex]\sqrt{16 +16}[/tex]) / 2
x = (4 ± 4[tex]\sqrt{2}[/tex]) / 2
x = 2 ± 2[tex]\sqrt{2}[/tex]
Your variable being solved is a so a = 2 ± 2[tex]\sqrt{2}[/tex]

how would you prefer to see your quiz score,as a fraction or as a percent? Explain. (what would you choose and why?)
For me, a percent is easier to think about. Knowing I scored 80% make sense. 80%, like 80¢ out of a dollar, makes sense and I can relate to it.
If you tell me I scored 52/65, I can't relate to that as easily, even though that's still 80%.
Anthony drives 15 km at 40 kph and return at the rate of 60kph , what is the average rate for the entire round trip
9514 1404 393
Answer:
48 kph
Step-by-step explanation:
The distance is immaterial, as long as it is the same at both speeds. The total time for some distance d is ...
t = d/40 +d/60
And the average speed is ...
2d/t = 2d/(d(1/40 +1/60) = 2/(1/40 +1/60) = 2(40)(60)/(40+60) = 4800/100 = 48
The average rate for the round trip is 48 kph.
_____
Additional comment
This value is called the harmonic mean of the two speeds. It is the reciprocal of the average of the reciprocals of the speeds.

Give a convincing argument with logical explanations that the contrapositive of a conditional is the
same as the converse of the inverse of the conditional
Answer:
see explanation. (I did this exact assignment this morning, and this is very similar to what I submitted)
Step-by-step explanation:
The contrapositive of a conditional is the same as the converse of the inverse of the conditional.
The best way to prove/support this statement is to create an example. You should start by creating a conditional; you can then form the conditional's converse, inverse, and contrapositive. Here is an example:
Conditional: If C, then D. (starting statement)
Converse: If D, then C. (conditional reversed)
Inverse: If not C, then not D. (opposite of the conditional)
Contrapositive: If not D, then not C. (reversed opposite of the conditional)
Based on the information from the example you gave, you can conclude:
The converse of the inverse: If not D, then not C. (reversed opposite of the conditional)
Because: The converse is the conditional reversed (If D, then C). The inverse of the converse, in this case, would then make it the opposite (If not D, then not C).
I have not yet received a grade on this assignment, but I know the information is correct; the amount of explanation you need to give really depends on how your teacher grades. Personally, I just submitted an example (similar to the one above) that was color-coded to help show the different parts of each statement.
I hope this helps! :)
1. What is the constant of proportionality?
2. What is the equation?
Answer:
y = 1/3a
Step-by-step explanation:
y = ka
1 = 3k
k = 1/3
Confirm constant: (4-1)/(12-3) = 3/9 = 1/3
1 = 3(1/3) + b
1 = 1 + b
b = 0
y = 1/3x or 1/3a

24⁄x = 2⁄1 solve for x, milk chocolate = 12.
milk chocolate (12) + plain chocolate (24)= 36 Total
