Answer:
531,441·g^6·h^8
Step-by-step explanation:
The operative rule of exponents is ...
(a^b)^c = a^(b·c)
Working from the inside out, according to the order of operations, we get ...
= (9^3·g^3·h^4)^2
= 729^2·g^(3·2)·h^(4·2)
= 531,441·g^6·h^8
Answer:
Since we know that ΔPQR is a right triangle, we can also asume that:
sin R = cos P = 3/5
So the answer is (d).
* This formular can also be applied to other right triangles.
In a right triangle, sine of one acute angle will always be equal to cosine of the other acute angle.
And we can check this by actually finding cos P using the lengths of the sides, by calculating PR first:
PR = √(PQ² + RQ²) = √(12² + 16²) = 20
=> cos P = PQ/PR = 12/20 = 3/5
146.65 becuase 12.3 plus 25.75 plus 108.6 equals 146.65
Hiya. I'm going to rewrite the second equation.
By subtracting 5x by both sides, I'll be able to have y by itself:
-y=-5x+13
I'm going to then divide both sides by -1 to get:
y=5x-13.
Then, I'm going to plug that equation into the first equation
3x+2(5x-13)=39
Factor:
3x+10x-26=39
Combine like terms:
13x=65
Divide both sides by 13 to get x by itself to get x=5
Plug this back into the equation of y=5x-13
y=5(5)-13 to get y=12
Answer:
red 8/32 = 1/4
purple 14 / 32 = 7/16
yellow 6/32 = 3/16
green 4 / 32 = 1/8
Step-by-step explanation:
if you add all the crayons together you get 32
you put each number over 32 and then divide it
