Area of the square = 11*11 = 121
Area of the circle = pi r^2 = pi*1^2 = 3.142
Part A
P( hitting the circle = 3.142 / 121 = 0.026 which is closer to 0.
Part B.
P( hitting the white portion) = 1 - 0.026 = 0.974 which is closer to 1.
Density = Mass/Volume => Volume = Mass/Density = 12/3.1 = 3.87ml
5x+25=85
Add 25 because he already saved that amount of money
5x because 5 is the amount of money he makes a week and x= number of weeks.
And =85 because that’s the total cost
To find the amount of weeks, just solve the equation
5x+25=85
5x=60
X=12 weeks
Hope it helps
Answer: -1
Step-by-step explanation:
Given: The set of points W(4, 4), X(6, 2), Y(-8, 16) are collinear
The slope of a line passing through points (a,b) and (c,d) is given by :-

Now, the slope of line passing through W(4, 4), X(6, 2) is given by :-

Hence, the slope of line passing through W(4, 4), X(6, 2), Y(-8, 16) =-1
Answer: In problem 8, the lines are not parallel. In problem 10, the lines are parallel.
To determine if the lines are parallel. You need to check if the segments form on each side are proportion.
#8 check to see if: 2/1 = 3/1.2
If you cross multiply, you get 3 = 2.4 which is not true, so the lines are NOT parallel.
#10 check to see if: 6/5 = 9/7.5
If you cross multiply, you get 45 = 45 which is true, so the lines are parallel.
