The Science Club went on a two-day field trip. The first day the members paid $60 for transportation
AlladinOne [14]

Answer:

day 1 total $60+$15=$75

day 2 total $95+$12=$107

total 2 days = $181

Step-by-step explanation:

Answer:

Total cost for two days for the n members of the club = 155 + 27 n

Step-by-step explanation:

Total number of persons = n

The first day the members paid $60 for transportation plus $15 per ticket to the planetarium.

Day 1 cost = 60 + 15 x n = 60 + 15 n

The second day they paid $95 for transportation plus $12 per ticket to the geology museum.

Day 2 cost = 95 + 12 x n = 95 + 12 n

Total cost = Day 1 cost + Day 2 cost

Total cost = 60 + 15 n + 95 + 12 n = 155 + 27 n

Total cost for two days for the n members of the club = 155 + 27 n

Plz this is due today help me explain the answer
Natali [406]

Answer:

177.3 feet

This is a classic find the vertex of a parabola question.

if this was a calculus class the solution would be to take the derivative and set it equal to zero... -32t+ 105 = 0

BUT i assume that you are not in a calculus class..

so we try plan "B" the  highest (or lowest) point of parabola is it's vertex

the vertex formula is [-b/2a,f(-b/2a)]

in your problem a = -16, b=105, c= 5

so the "X" (TIME) is located at -(105)/(2*-16) = 3.28

plug in 3.28 into -16(3.28)^2 + 105(3.28) + 5 = 177.27

and you will get

A case of snickers contain 20 snicker bars. Joe paid $30 for 2 cases of snickers bars. To fill the vending machines, he needs 14
Angelina_Jolie [31]

Answer:

$105

Step-by-step explanation:

$15 for one case of snicker bars. Since it's $30 for 2. He needs 140 so 140 divided by 20(which is in one case) = 7. So he needs 7 cases to have 140 snicker bars. Well, if each case itself is $15 and we need 7 cases. 7 times 15= 105. It's going to cost him $105 to fill that vending machine.
