Answer: option D. 0.785
Explanation:
1) the probability will be equal to the area of the shaded region divided by the area of the rectangle:
area of the shaded region
probability = -------------------------------------
area of the rectangle
2) call r the radius of the circles (all are equal)
area of one circle = π (r^2)
area of the four circles = 4π(r^2) = area of the shaded region
3) area of the rectangle
length of the rectangle: 2r
height of the rectangle: 8r
area of the rectgangle = (2r)(8r) = 16 r^2
4) probability = 4π(r^2) /[(16)(r^2)] = π / 4
use π = 3.1416
probability = 3.1416 / 4 = 0.785
And you do not need to use the diameter given. The answer does not depend on this number.
The answer is $73
Explanation:
since you are buying five shirts for nine dollars each you would need to do 5x9 which equals 45. Now you need to do 12x2 since you bought two pairs of pants for twelve dollars each. 12x2 equals 24. Now you need to add 24 and 45 to see what your price is. 24+45=69. Now add on four dollars for shipping and handling and you will have $73 dollars. Hope this helps!
11: To add 3/8 and 2/5 you need to find the least common denominator (in this case 40), and change both fractions by multiplying to get the least common denominator and add them together
2/8 = 10/40
2/5 = 16/40
16/40 + 10/40 = 26/40 = 13/20
12 a: 5/6 = 45/54
4/9 = 24/54
45/54 - 24/54 =21/54
b: 7/10 = 56/80
3/8 = 30/80
56/80 = 30/80 = 26/80 = 13/40
SAS (Side-Angle-Side): If two pairs of sides of two triangles are equal in length, and the included angles are equal in measurement, then the triangles are congruent. SSS (Side-Side-Side): If three pairs of sides of two triangles are equal in length, then the triangles are congruent.
We tripple something and get 10 more than something.
Put the x-es on the left and non x-es to the right,
Divide both sides by 2,
Et Viòla.
Hope this helps :)
