The whole circle is 360° and the unknown non-shaded area can be found by subtracting 360 - 64 - 48 (shaded areas) - 165 (known non-shaded area) which is 83°. The non-shaded area is 83° + 165°, or 248°.

To find the probability of landing on a non-shaded area, divide 248 / 360; that is equal to 0.688 repeating so the answer is B) 0.69

Novay_Z [31]

Answer:

5x+8y

Step-by-step explanation:

We can first open the brackets by using the distrubitive propety.

2(x+4y)+3x

2x+8y+3x

Now we can combine like terms.

5x+8y.

I combined the 3x and the 2x. This works because imagined I have 3 of something then I got 2 more of that something I would now have 5 of that something.

Door is 77 inches high, 35.25 inches wide and 1,75 inches thick how much paint is needed
Leviafan [203]
If you wanted to paint the entire door (even the top and bottom which people don't usually paint)

the surface area is
SA=2(LW+LH+WH)
where L=length, W=width and H=height

given
L=35.25
W=1.75
H=77

SA=2(35.25*1.75+35.25*77+1.75*77)
SA=2(61.6875+2714.25+134.75)
SA=2(2910.6875)
SA=5821.375

you need enough paint to cover 5821.375 square inches of door
