Answer:
95 square inches
Step-by-step explanation:
Start by finding the surface area of the four triangles. 7x5=35 35÷2=17.5. 17.5x4=70. Then take the surface area of the square, 25, and add it to the surface area of the triangle. 70+25=95.

Step-by-step explanation:
The general for for the equation of a circle is
Where a is the x coordinate of the centre, b is the y coordinate of the centre and r is the radius.
In your case, a=0, b=0, r=9
Substituting these values into the general form gives the answer.

Step-by-step explanation:
we have
0.888...
This is a <u>repeating decimal</u> (Is a decimal that has a digit, or a block of digits, that repeat over and over and over again without ever ending)
Convert to fraction number
Let
x=0.888...
10x=8.888...
Subtract 0.888... from 8.888... to remove the decimal
10x-x=8.888...-0.888...
9x=8
Solve for x
x=8/9
therefore
Mike fraction is incorrect
because 4/5=0.8
0.8 is a <u>terminating decimal </u>(It's a decimal with a finite number of digits)
Mike's mistake was considering the number as a terminating decimal instead of a repeating decimal
Beth is correct
because
If you divide 8/9
the result is 0.8888888...
