Your answer is the one on the bottom left
The width is x
<span>The length is x+60 </span>
<span>so x(x+60) = 16000
</span>
<span>x^2 + 60x = 16000
</span>
<span> </span>
<span>x^2 + 60x + 900 = 900+16000
</span>
<span>(x+30)^2 = 16900
</span><span> </span>
<span>x+30 = 130
</span>
<span>x = 100
So your answer is 100. </span>
Answer:
a) 77.13
b) 179.97
Step-by-step explanation:
3x + 3x + 4x + 5x + 6x + 7x = (6 - 2) × 180
28x = 720
x = 720/28
x ≅ 25.71
3 × 25.71 = 77.13 = smallest angle
7 × 25.71 = 179.97 = largest angle
Solve using system of equations.
y=total money spent, x=amount of rides
y=12+3.5x
y=33
Solve! Set them equal to each other
12+3.5x=33
-12 -12
3.5x=21
x=6
After six rides the all day pass would be cheaper. ;)
7)alternate exterior angle or supplementary angles
8)81
