The first step to solve this problem is to compute first for
the area of the bigger rectangle:
A = LW
A = 12m (10m)
A = 120 m^2
Next step is to find the area of the smaller rectangle:
A = LW
A = 7m (2m)
A = 14 m^2
The last step is to deduct the area of the smaller rectangle
to the area of the larger rectangle:
Area of larger rectangle – Area of the smaller rectangle =
Area of the shaded region
120 m^2 – 14 m^2 = 106 m^2
Therefore, the area of the shaded region is 106 square
meters.
Answer:
136112 
Step-by-step explanation:
since the outer circle is 25cm wider on one side, the radius of outer circle is 25 cm wider. (imagine rotating the green line to match with the pink line, you'll see the outer circle radius more clearly)
r of inside circle = 148.4/2 = 74.2
r of outside circle = 74.2 +25 = 99.2
the shaded region = A of outer circle - A of inner circle
=3.14(99.2)^2 - 3.14(74.2)^2
area of a circle is 
, I plugged in known values above^.
= 30899.6096 - 17287.7096 = 13611.9 (I definitely recommend a calculator)
rounded to nearest whole number = 13612
The domain for exponential functions will be all real numbers. Then the correct option is C.
<h3>What are domain and range?</h3>
The domain means all the possible values of x and the range means all the possible values of y.
The exponential function is given as,
Let a be the initial value and x be the power of the exponent function and b be the increasing factor. The exponent is given as
y = a(b)ˣ + c
Where c is the addition constant.
The domain for exponential functions will be all real numbers.
And the range of the exponential functions will depend upon the equation.
Then the correct option is C.
More about the domain and range link is given below.

Answer:
68%
Step-by-step explanation:
We observe that the mean of the sample is (61+71)/2 = 66 mph which means the standard deviation of the sample is 5 because 66-5=61 and 66+5=71. The Empirical Rule states that for data observed in a normal distribution, 68% of data will fall within one standard deviation of the mean. Therefore, approximately 68% of vehicles travel between 61 miles per hour and 71 miles per hour.
