Aradio station is giving away 40 concert tickets. the station gives away 2 tickets every hour on the hour of hours until there are at most 4 tickets left a grand prize. if the contest runs from 11: 00 a. m to 1: 00 p. m each day, for how many days will the contest last?

About 6 days

Step-by-step explanation:

We know that 11-1 has 3 hours in it. Each hour has 2 tickets given away. we then multiply the two numbers to find the total in one day. 2(3)=6

However, it wants to know when it has 4 at most left. SO 40-4=36

We know that  6 is the total given in 1 day therefore we use that to find how many days.

Take the total tickets after subtracting 4 (36) and divide by the total given away a day (6)

36/6= 6

Meaning a total of 6 days

answer: standard form is ax^2 + bx + c = 0

step-by-step explanation:

standard form is ax^2 + bx + c = 0

(2x + 1)(x - 2) = 0

distribute to get into standard form

2x^2 - 4x + x - 2 = 0

2x^2 - 3x - 2 = 0

a = 2, b= -3, c = -2

a is your answer

step-by-step explanation:

the true ones are a b and d
