Answer:
The area of the shaded region is 5.86\ cm^{2}
Step-by-step explanation:
The area of the shaded region is equal to the area of the rectangle minus the area of the circle
The rectangle is a square
so
A=b^{2} -\pi r^{2}
we have
b=3\ cm
r=1\ cm
assume
\pi =3.14
substitute the values
A=3^{2} -(3.14)(1)^{2}
A=5.86\ cm^{2}
The awnser is 4 1/6
i did this by multiplying 5/6 times 5
3A^2 dA/dt + 3B^2 dB/dt = 0
If A=2, then 8+B^3=9, B=1
12 dA/dt + 9 = 0
dA/dt = -3/4
Answer:
40 miles
Step-by-step explanation:
Let's set <em>x</em> to the number of miles driven, and <em>t</em> to the number of hours it took to drive.
We know that 40<em>t</em> is equal to <em>x</em>.
We also know that 40<em>t</em> is equal to 30(<em>t</em> + 1/3).
Solve for t:
40t = 30(t+1/3)
40t = 30t + 10
Subtract 30t from both sides:
10t = 10
Divide 10 from both sides:
t = 1
40t = 40 x 1 = 40 miles
