Answer:
Two supplementary angles = 180°
Two complementary angles = 90°
Answer:
Step-by-step explanation:
Convert the mixed number in the denominator to an improper fraction by multiplying the big number times the denominator and adding the numerator.
Leave the same denominator.
Let's do the same with the fraction in the numerator.
Our new division is;
Now, to get rid of the fraction in the denominator, multiply by the reciprocal fraction. The reciprocal is the inverted fraction.
If our fraction is the reciprocal is
This eliminates the denominator.
Now convert this fraction to a mixed number by dividing.
64/35=1
35
-------
29
-------------------------------------------
1 is the big number, 29 the numerator and 35 the denominator.
Do not forget about the negative sign in front of it.
Answer:

Step-by-step explanation:
The amount of basket balls depends on the money rasied and is therefore dependant, that leaves the money, which is completely independent.
Answer:(x^2+y^2)^2=(x^2+y^2)(x^2+y^2)
Step-by-step explanation:
We can rewrite left side into right side form
(x^2+y^2)^2=(x^2+y^2)(x^2+y^2)
we can expand it
(x^2+y^2)^2=x^4+x^2y^2+x^2y^2+y^4
(x^2+y^2)^2=x^4+y^4+2x^2y^2
we can add and subtract 2x^2y^2
(x^2+y^2)^2=x^4+y^4+2x^2y^2+2x^2y^2-2x^2y^2
(x^2+y^2)^2=x^4-2x^2y^2+y^4+2x^2y^2+2x^2y^2
(x^2+y^2)^2=x^4-2x^2y^2+y^4+4x^2y^2
(x^2+y^2)^2=x^4-2x^2y^2+y^4+(2xy)^2
(x^2+y^2)^2=(x^2-y^2)^2+(2xy)^2
Answer:
each solo act will last 5 minutes and each ensemble act will last 14 minutes
Step-by-step explanation:
In the first show, we are told that there are 12 solo acts and 3 ensemble acts.
Now since each solo act lasts x minutes, and each ensemble act lasts y minutes and the show lasts 102 minutes, thus we have;
12x + 3y = 102 - - - - eq1
In the second show which lasts 72 minutes, we are told that there will be 6 solo acts and 3 ensemble acts.
Thus,we have;
6x + 3y = 72 - - - - eq2
Now, let's find x and y by subtracting eq 2 from eq1 to give;
6x = 30
Divide both sides by 6 to give;
x = 5
Put 5 for x in eq2;
6(5) + 3y = 72
30 + 3y = 72
3y = 72 - 30
3y = 42
y = 42/3
y = 14
Thus, each solo act will last 5 minutes and each ensemble act will last 14 minutes
