Answer:
The correct answer is last option 78.5%
Step-by-step explanation:
Points to remember
Area of circle = πr²
Where r is the radius of circle
Area of square = a²
Where 'a' is the side length of square
<u>To find the area of circle</u>
Here r = 10 cinches
Area = πr²
= 3.14 * 10²
= 3.14 * 100 = 314
<u>To find the area of square</u>
Here a = 20 inches
Area = a²
= 20²
= 400
<u>To find the probability percentage</u>
Probability = area of circle/Area of square
= (314/400)*100
78.5 %
Answer:
3.33
Step-by-step explanation:
There were...
11cards left.
heres why.
they started with 24 cards....
so...
24+8=32
32-12=20
20-9=11
Hope i helped!!! :)
Mark me as brainliest if i helped XD
Answer:
the slope of the line in the graph is: 3
the y-intercept is: -4
the equation of the line is: y=3x-4
Step-by-step explanation:
If we find a point on the graph and count it until it reaches other solid point we get that you have to go up three and to the right by one. This solid point I looked at was (0,-4) and counted up to (-1,1). To find the slope, we have to simply count and use "rise over run". The rise is 3 for every 1 we run, making the slope 3/1 which is 3.
the y-intercept is the point on the graph that touches the y-axis on the graph. The only point on the graph that touches the y-axis is -4, making the y-intercept -4.
The equation for a graph is y=mx+b. m would be the slope and b would be the y-intercept. We know that the slope is 3 (m) and that the y-intercept is -4 (b). Putting them together, we get that the equation of the graph is y=3x-4.
