Theoretical probablity=desiredoutcomes/totalpossibleoutcomes
desired=number of white marbles=20
total possible=red+blue+white=30+50+20=100
so theoretical probablity=20/100=2/10=0.2=20%
26 by 9
Area = L*W
Area = 26 * 9
Area = 234 square feet but there are 2 such walls
Area = 234 * 2
Area = 468 square feet total for these walls.
18 by 9
Area = L*W
Area = 18 * 9
Area = 162 square feet
Total area = 468 + 162 = 630 square feet.
1 gallon covers 250 square feet
x gallon covers 630 square feet
1/x = 250/630
250 x = 1 * 630
x = 630 / 250
x = 2.52 gallons. It is best that she buy 3 gallons of paint.
Answer:
1/52
Step-by-step explanation:
Answer:
1. I, II,
Step-by-step explanation:
<em>I. Diagonals are perpendicular bisectors of each other </em>
Yes, because 4 sides are congruent so it makes the two diagonals perpendicular bisectors
<em>II. Diagonals bisect the angles from which they are drawn </em>
Yes, That is the property of the diagonal!
<em> III. Diagonals form four congruent isosceles right triangles. </em>
No, only two pairs of right triangles are congruent and sometime the side of each pair are different to each other.
Hence, we choose I and II
