A skydiver begins by free-falling, and then uses a parachute to float the rest of the way to the ground. The relationship between the skydiver's height while free-falling (in m above the ground), t seconds after jumping, is given by h=-1.7t^2+3050. The relationship between the the skydiver's height while using the parachute (in m above the ground), t seconds after jumping, is given by h=-5t+1650. When did the skydiver pull her parachute, and how high above the ground was she when she did this?

75 tickets have been sold so far.

step-by-step explanation:

in this question it is clearly mentioned that 45 children's tickets have been sold and this number is 60% of the total tickets sold.

now let's assume the total number of tickets sold be x.

then 60% of x = 45

⇒

⇒ x(.6) = 45

by dividing with .6 on both the sides of the equation

⇒ x = 75

therefore 75 tickets have been sold so far.

he can buy 4lbs. of live bait and 1lbs of natural bait

step-by-step explanation:

x² + 11x + 18 < 0  

[-11 ± sqrt(121 - 72)]/2 = (-11 ± 7)/2  

solution: (-9, -2)

step-by-step explanation:

b because it contains 40% of the possible results from the random list.  

0,1,2,3 v 4,5,6,7,8,9  

4 integers to 6 integers  

40% success vs 60% fail
