To solve this question we need to add 1hr 30mins onto 7:00 am:
1 hour later would be 8:00 am
30 mins later would be 8:30 am
You will get to school at 8:30 am
Hope this helps!
Answer:
144 square inches
Step-by-step explanation:
Total surface area of the rectangular prism = Sum of all the area of its sides
Since it has a square base which can be covered by 16 squares of length 1 inch each, then;
length of its base = 4 inches
So that,
i. Area of its base = 
= 
area of its base = 16 square inches
ii. Area of one of the surfaces of its sides = length x width (or base x height)
= 4 x 7
= 28 square inches
Sum of the area of its vertical sides = 4 x 28
= 112 square inches
Thus,
Total surface area of the prism = 16 + 16 + 112
= 144 square inches
X is greater than or equal to 5 and less than or equal to 10.
Now x is given, which is 9 and y = 20(9)
y = 180.
Is y > 80?
If yes then z = y+ 20.
If no then z = y - 10.
The solution we got for y is 180 and is greater than 80, so above statement is true.
z = y + 20
z = 180 + 20
z = 200
Answer: 200
Long Piece: 5x
Short Piece: x
(x) + (5x) = 72
6x = 72
x = 12
Long Piece: 5x = 5(12) = 60
Answer: 12 cm and 60 cm

Step-by-step explanation:
Question not written well
The equation of the ball is meant to be in a parabola or trajectory form.
So, h = -4.912t² + 24.5t + 1
The ball will hit the ground when the height is 0
I.e. h= 0
Therefore,
-4.912t² + 24.5t + 1 = 0
Using almighty formula,
a = -4.912 b = 24.5 c = 1
t = (-b±√b²-4ac) / 2a
t = (-24.5±√24.5²-4×-4.912 × 1) / 2 × -4.912
t = (-24.5±√600.25 + 19.648) / 9.824.
t = (-24.5 ± 24.898) / 9.824
So,
t = (-24.5 + 24.898) / 9.824
t = 0.398 / 9.824
t = 0.04seconds
Or
t = (-24.5 - 24.898) / 9.824
t = -5.03 seconds
So, we are going to discard the negative time,
t = 0.04 second is the correct time the ball will hit the ground
