24/5 ÷ 6/15
= 24/5 × 15/6
= 360/30
= 12
for president, we have 12 possible options
12_
Once we’ve decided on a president we only have 11 possible people to choose from for vice president
12_11
multiplying these options together gives us:
12•11= 132
So the answer is C.132
Answer:
a, Row 1 = 30 seats
Row 2 = 32 seats
Row 3 = 34 seats
Row 4 = 36 seats
b, n + equidistant number of seats added each row (2) * number of row - 1
c, 58 seats
Step-by-step explanation:
a, Because the seats is increasing by 2 after every row after row 1
Therefore, row 2 = row 1 + 2 = 30+2 = 32 seats
Row 3 = Row 2 + 2 =32+2 =34 seats
Row 4 = Row 3 + 2 = 34 + 2 = 36 seats
b, The explicit rule for the number of seats would be:
Row 1 = n
Row 2 = n + equidistant number of seats added each row (2) * (2-1) = n + 2
Row 3 = n+ equidistant number of seats added each row (2) * (3-1) = n+ 4
Row 4 = n + equidistant number of seats added each row(2) * (4-1) = n+6
etc.....
c, The number of seats in the 15th row would be = number of seat in the first row + equidistant number of seats added each row * 15 - 1 (first row)
= 30 + 2 * 14= 30 + 28 = 58 seats
Hope this help you :3
