Answer:
h = 110.24 m
Step-by-step explanation:
It is given that,
A rock is thrown up from the ground at a velocity of 84 feet per second. The formula 
gives the rock's height in feet after t second.
We need to find the maximum height of the rock. For maximum height put 
So,
Put t = 2.62 s in the equation of height. So,
So, the maximum height of the rock is 110.24 m.
Answer: There are 4 tubes of paint she purchased.
Step-by-step explanation:
Since we have given that
Amount spend on tubes of paint and brushes for an art project = $16
Cost of each tube of paint = $3
Cost of each brush = $0.50
Let the price of tube of paint be 'x'.
Let the price of brush be '2x'.
So, According to question, it becomes,
Hence, there are 4 tubes of paint she purchased.

Step-by-step explanation:
Hi there!
Assuming a perfect square: we know there are 4 sides in a square, and all of them have equal length. This means that every side of the square is 6 cm, and with 4 sides, that would make an overall length / perimeter of 6 + 6 + 6 + 6, or 6*4, which would equal 24 cm. This means that our wire must be 24 cm long.
Now, for the rectangle. We know with rectangles that they also have 4 sides, and in pairs of 2 in terms of length (2 of the sides have the same length, and the other two have the same length). This means we know there are 2 sides that are 9 cm, which would mean 18 cm in total. This is the total amount of wire taken up by the length, but we are looking for the width. Thus, we can see how much wire is leftover not taken up by the length by subtracting 18 from 24:
24-18=6
Now, we see that the two sides that make up the width are 6 cm long. As those two sides are equal length, we can divide 6 cm into two equal parts to see the width.
6/2 = 3 cm.
Thus, the width of the rectangle is 3 cm.
Hope this helps!
