Answer:
6.74 s
Step-by-step explanation:
y = ½ at² + vt + h
Given a = -32, v = 80, h = 188:
y = ½ (-32) t² + (80) t + (188)
y = -16t² + 80t + 188
When y = 0:
0 = -16t² + 80t + 188
0 = 4t² − 20t − 47
Solve with quadratic formula:
t = [ -(-20) ± √((-20)² − 4(4)(-47)) ] / 2(4)
t = [ 20 ± √(400 + 752) ] / 8
t = (20 ± √1152) / 8
t > 0, so:
t = (20 + √1152) / 8
t ≈ 6.74
Answer:
60,000
Step-by-step explanation:
59,000 + 1,000 = 60,000.
As for the division part, you have not provided any information on that part of the question, such as what to divided 60,000 by, so I will not be able to answer.
Hope this helped!

Step-by-step explanation:
PLATO
Answer:
85 square inches
Step-by-step explanation:
The surface area is the area of all the sides and the bottom
The area of the bottom is
A = s^2 since it is a square
A = 5^2 = 25 in^2
The sides are triangles
A = 1/2 bh where b is the base and h is the height
A = 1/2 ( 5)(6)
A = 15 in^2
We have 4 sides
The area of the 4 sides
4*15 = 60 in^2
Add the area of the side to the bottom
25+60 = 85 in^2
