A. {9,10,11,12}
9 and 10 are elements of set A but 11 and 12 aren't elements of A.
Subsets of A
{ } {1} {2} {3} {4} {5} {6} {7 } {8} { 9} {10}
{1,2} {1,3} {1,4} {1,5} {1,6} {1,7} {1,8} {1,9} {1,10} {1,2,3} {1,2,4} {1,2,5}........ you can write like this using all the elements of A
The answer is D) Seventh and eighth grade students at the school preferred an eagle mascot.
This is because both Tiger and Eagle had 40 votes, so it couldn't be A) or B), as they both had the same number of votes. It also couldn't be C) because more fifth and sixth grade students voted for tiger than eagle. It could only be D) as more seventh and eighth grade students DID actually vote for the eagle mascot rather than the tiger mascot.
The surface area of the right prism with an isosceles triangle base is 720 inches squared.
<h3>Surface area of a triangular prism</h3>
surface area = bh + l(x + y + z)
where
- b = base of triangle.
- h = height of triangle.
- l = height of the prism.
- x, y and z are the side of the triangle.
Therefore,
b = 24 inches
h = 5 inches
x = 13 inches
y = 13 inches
z = 24 inches
l = 12 inches
Surface area = 24 × 5 + 12(13 + 13 + 24)
Surface area = 120 + 12(50)
Surface area = 120 + 600
Surface area = 720 inches²
