Answer:

Step-by-step explanation:

so I can't see the picture or what the "Shaded region " is.. but I can guess that it's the part of the  3x3 rectangle with the circle removed.. right?

if that's the case... then

3*3 = 9 cm^{2}

9 - area of circle = shaded region

area of circle = pi * r^{2}

pi * 1 cm = 3.1415  cm^{2}

9 cm^{2}  - 3.1415  cm^{2} = 5.8585 cm^{2}

5.86 cm^{2}

I don't see this as a choice of answers so maybe that's not what the shaded region is.  any way.. hope it helps

Andrews [41]

The value of 7 in 26..74 is 0.7

The value of 7 in 37.596 is 7.

1/10 the value of 7 in 26.74 is 0.07 and 0.07 ≠ 7.

So, statement c) is incorrect.

100 times the value of 7 in 26.74 is 70 and 70 ≠ 7.

So, statement d) is incorrect.

10 times the value of 7 in 26.74 is 7 and 7 = 7.

So, statement b) is correct and it correctly compares two values.

All you have to do for this is take your inches (18 7/10 or 18.7) and divide it by the number of hours (12) which makes 1.56in per hour.
