A local high school is raffle off a college scholarship to the students in its junior class, If a girl has a 0.55 chance of winning the scholarship and 154 of the juniors are girls, how many of the juniors are boys? (Assume that every junior has an equal chance to win.)

126

Step-by-step explanation:

55% of student population is girls

if there are 154 girls then
0.55x = 154, where x represents school population

x=280

assuming the school only has boys and girls, anyone that's not a girl must be a boy, so

boys = 280 - 154 = 126.

if the school is not only boys and girls,

there will be 126 or less boys

3 1/3 x 2 3/5 = 8 2/3

step-by-step explanation:

just multiply the first number by the second number to get your answer.

false

step-by-step explanation:

false.   two legs of the trapezoid would be congruent, but the other two would not.   were all the legs congruent, then we'd have a square; were the 2 shorter sides congruent and the 2 longer sides also congruent, we'd have a rectangle.
