Figure WXYZ is a rectangle with a semicircle added to its base.What is the perimeter of figure WXYZ? Use 3.14 to approximate pi.

Answers

Figure WXYZ is a rectangle that has a semicircle added to its base. The rectangle has a length of sixteen inches and a width of seven inches. The semicircle has a diameter equal to the length of the rectangle.

Given:
Rectangle: Length = 16 inches ; width = 7 inches
Semicirle added to its base, the length of the rectangle. Only one length.

We need to get the circumference of the semi circle and add the length and 2 widths of the rectangle.

Circumference of a circle = 2πr ⇒ 2 * 3.14 * 8 inches = 50.24
Circumference of a semicircle = 50.24/2 = 25.12 inches
Widths of the rectangle = 2 * 7 inches = 14 inches

Perimeter of the figure = 25.12 in + 14 in + 16 in = 55.12 inches.

45° I think because 45° is half of 90° and no polygon interior angle is less than 90°

Harry and Terry are each told to calculate 8−(2 5). Harry gets the correct answer. Terry ignores the parentheses and calculates 8−2 5. If Harry's answer is H and Terry's answer is T, what is H−T?GIVE U MANY POINTS!!!!!!!!!!

Answers

I'm pretty sure the space is a "+".

so the question was 8-(2+5) which is eual to (first the bracket) 8-7, which is 1

 H=1

if you ignore the bracket you have 8-2+5, which is (first the left side) 6+5, which is 11

T=11

and H-T=1-11=-10!

Is 31.010 greater or less than 31.01

Answers

31.010 is equal to 31.01. This is because 31.010 and 31.01 is the same thing. 31.010 is just adding a zero at d end and 31.01 has no zero but it is the same thing as 31.010.

So, 31.010 = 31.01

Hope I helped ya!! 
They are equal, you just can add 0's to the last digits of number and it's still the same.
