All angles add up to be 180 degrees, so:
1X+2X+3X=180
6X=180
X=30
smallest angle=30 degrees
medium angle=60
largest angle=90.
Answer: It would take 8 hours!!
Step-by-step explanation: Hope this helps!! <3
<span>so to factor the trinomal:
z^2+18z+81
In this problem 9*9=81 and 9+9=18, so insert 9 as the right hand term of one factor and 9 as the right-hand term of the other factor.
(z+9)(z+9)
Combine the two common factors of (z+9) by adding the exponents.
(z+9)^2</span>
Answer:
(-2,-1)
Step-by-step explanation:
y=2x+3
y=3x+5
so y=y
then:
2x+3=3x+5
3-5= 3x-2x
-2= X
x=-2
Answer:
8.55 inches tall
Step-by-step explanation:
equation: h = -0.75t +12. The slope is -0.75 because that's the rate of the candle burning, and the y intercept is 12 because that's how tall it is initially.
Now plug in 4.6 for t you get:
h = -0.75t + 12
h = -0.75(4.6) + 12
h = -3.45 +12
h = 8.55 inches tall
