Answer:

3 3/8 seconds.

Step-by-step explanation:

When it reaches the ground h = 0 so:

54t - 16t^2 = 0

16t^2 - 54t = 0

2t(8t - 27) = 0

t = 0 or t =  27/8   (we ignore the t = 0 ) so:

t =   3 3/8 seconds.

Morgan has $60 to spend on clothes. he wants to buy a pair of jeans for $25 and spend the rest on t shirts each t shirt costs $5
Mashutka [201]

Answer:

C

Step-by-step explanation:

Morgan has $60. That is his spending limit.

He buys a pair of jeans for $25.

Each T-shirt is $5

We don't know how many t-shirts he can buy, so we can represent it with a variable, x

so,

25 + 5x \leq 60\\5x \leq 60 - 25\\5x \leq 35\\x \leq \frac{35}{5} \\x\leq 7
