10, 24, and 38.
A composite number is the opposite of a prime number: it can be dived by numbers other than 1 and itself.
As the ball hits the ground, its height will be equal to 0, so...
-3t² + 12t + 63 = 0
t² - 4t - 21 = 0
Using the Viet's theorem to solve the quadratic equation quicker:
t₁ + t₂ = 4
t₁t₂ = -21
t₁ = -3 - this is not possible because time can't be negative
t₂ = 7
That means, the ball is expected to hit the ground after 7 sec has passed.
The relationship between the miles and the total cost is, for every 1 mile at the cost of $.40 you will have to pay an initial fee of $1.75.
The charge for a one-mile drive is $2.15 (C=.40*1+1.75)
The charge for a 2.7 mile ride will be $2.83 (C=.40*2.7+1.75)
Answer:
Hi! You just have to take his salary as a unity (one) and substract the fractions you are given. For example; lets say you have a cake (one) and then you eat 1/8 of it. You would be left with

Firstly, do not try to revive the boat engine, it will make mud to enter the engine and clog it up. Drop the sail and try and find out where the deep water lay, so that you will not allow the boat to go that way. Determine the current tide of the water, kedge the boat and try to ease it out of the water in the direction of the tide. If all these fail, call the towing service.
