Answer:
5in x 10in
Step-by-step explanation:
Solution:
1. You have to assume that the ring will land on the board and as a result, just focus on one rectangle of the board since they are all the same size.
2. For the ring to land entirely inside the rectangle, the center of the ring needs to be 1.5 inches inside the border (radius is 1.5 inches), so the "winning rectangle" will have dimensions:
L = (x - 2(1.5)) = x - 3
w = (2x - 2(1.5)) = 2x-3.
3. Now, we will set up and solve our geometric probability equation. The winning rectangle's area of (x-3)*(2x-3) divided by the total rectangle's area of x*(2x) = 28%
(2x-3)*(x-3)/(2x^2) = .28
2x^2 - 9x + 9 = .56x^2
1.44x^2 - 9x + 9 = 0
4 . Now you can plug that in the quadratic formula and get the solutions x = 1.25 or 5. However, it cannot by 1.25 because that is too small of a dimension for the the circle with diameter of 3 to fit in, the answers has to be 5.
5. As a result, the dimensions of the rectangles are 5in x 10in.
Answer: 210
Step-by-step explanation:
55×12=660-500=160+50(down payment)=210
Answer:
120°
I just used a protractor tool lol. I looked it up afterwards as well and 120° is correct.
It’s c I just google the answer and did the test it’s c
Area of rectangle: 7 x 10 = 70 in2
Area of semicircle: (r^2*π)/2 = 3.5^2 * π /2 = 6.125*<span>π
</span>
=> Total area = 70 + 6.125*<span>π = 70 + approx 19.24 = approx. 89.24 in2</span>
------------------------------------------------------------------------------------------------------
The closest number here is 89 in2, so the answer is 89 in2.
