Answer:b
Step-by-step explanation: a line segment paralle to ab
Answer:
≈ 62.8
Step-by-step explanation:
Using the equal ratios of
= 
, that is
= 
= 5, thus
5 × sector = 100π ( divide both sides by 5 )
sector = 20π = 20 × 3.14 = 62.8 units²
Answer:
y = -1/3x + 8
Step-by-step explanation:
If two lines are perpendicular, the signs of the slope must be opposite and the slopes are reciprocals.
(basically if one is say -2/3, the other is 3/2. just flip it upside down)
So this slope is 3, so the new slope should be -1/3
The equation is now y = -1/3x + b
To find b, substitute (-9,5) in the equation
y = -1/3x + b
5 = -1/3(9) + b
5 = -3 + b
8 = b
So the equation is y = -1/3x + b
Probablity is (desired outcomes)/(total) possible outcomes
so the dice
1 is desired and the total poassible outcomes is 6 since 6 numbers
so probailty of rolling a 1 is 1/6
then flippin heads
desired outcome=1
total possible=2
probabilty is 1/2
so we have 1/6 and 1/2
now we mulitply them
1/6 times 1/2=1/12
the answer is A
