Answer:
11: Diameter
13: 10 cm
Step-by-step explanation:
Diameter is a straight line across a circle.
It would be 10 because if you cut 20 in half, which is the whole distance of the line, you would get 10.
Answer:
8a(5a - 4)
Step-by-step explanation:
To factor this expression, see what numbers and variables these two terms have in common. I can see that they both have the variable a, so a can be factored out.
40 and -32 also have 8 in common, because they are both cleanly divisible by 8.
Now we can factor 8a out of 40a^2 - 32a. Think of how many times 8a goes into 40a^2 and -32a.
8a(5a - 4)
4.4 is the answer cause 5.6 plus 4.4 is 10
Answer:
D. {R, G, Y, B}
Step-by-step explanation:
Number of balls = 4
red ball (R) = 1,
green ball (G) = 1,
yellow ball (Y) = 1,
blue ball (B) = 1
therefore the Pr (choosing a ball) = 1/4
but the sample space (the possibilities of either choosing any color of the balls) will be {R, G, Y, B}
20 -- 55
1/8 -- x
(1/8)*55/20=55/160≈0.34 feet
