Answer:
The radius of the circle is 
Step-by-step explanation:
we know that
The circumference of a circle is equal to
In this problem we have
substitute and solve for r
1 out if 20 you would get right
There is 5 questions 4 answers to pick from so 5 times 4 is 20
Then they said what is the probability of only getting one answer right
So the answer would be 1 out of 20 1/20
List the coordinates,
Coordinates are shown as (x,y)
If 2+2+7+7 is 16
You make those your side lengths
Coordinates are (9,7) (2,7) (2,5) (9,5)
they maybe slightly off because of the broken peice of paper
Answer:
x = 8, y = 3
Step-by-step explanation:
Equating corresponding x and y coordinates , then
- y = - x + 5 ( multiply through by - 1 )
y = x - 5 → (1)
2x - 5y = 1 → (2)
Substitute y = x - 5 into (2)
2x - 5(x - 5) = 1 ← distribute and simplify left side
2x - 5x + 25 = 1
- 3x + 25 = 1 ( subtract 25 from both sides )
- 3x = - 24 ( divide both sides by - 3 )
x = 8
Substitute x = 8 into (1) for corresponding value of y
y = 8 - 5 = 3
Use formula y2-y1 over x2 - x1
3-0/4-0
3/4 is ur answer
