When you are subtracting over zeroes, you may need to carry over. This being said, you may need to take some from a previous number and put it into a zero, and continue carrying over until you can do what you needed to do. If you don't know the place value of the zero in mind, you will not end up completing this correctly.
Answer:
a = 40 degrees
Step-by-step explanation:
the inscribed angle of 200 degree arc is 100 degrees.
the sum of all the interior angles of a triangle is 180 degrees so:
angle a = 180 - 100 - 40 = 40 degrees
Answer:
A. 4.5 ft
B. 4 ft
C. 1 ft
Step-by-step explanation:
If you pretend that h is replacing y and d is replacing x and you would graph the equation, then you would get a parabola that opens down.
You would need to find the vertex of the parabola. The ordered pairs would be (d, h) instead of the normal (x, y).
A. The maximum height will be the h value of the vertex
B. Let h = 0 and solve the equation for d. That will give you distance from the stump that the frog landed.
C. The distance from the log at the maximum height is the d value of the vertex
So, that is what is needed to be done.
Without me going thru all the work, the vertex is (1, 4.5) and the solutions to the equation when h = 0 are 4, -2 (discard -2 since a distance cannot be negative)
So the answer to A is 4.5 ft.
The answer to B is 4ft.
The answer to C is 1 ft.
Now, can you find the vertex on your own and can you solve the equation when h = 0? I hope so. OK?
Complete question :
A swimming pool is the shape of a right rectangular prism. If the pool is 12 3/4 yards long, 5 2/3 yards wide, and 9 yards deep, what is the volume of the swimming pool
Answer:
650 1/4 yd³
Step-by-step explanation:
Volume of a rectangle prism :
V = Length * width * height
V = 12 3/4 * 5 2/3 * 9
V = 51/4 * 17/3 * 9/1
V = (51*17*9) / (4*3*1)
V = 7803 / 12
V = 650 3/12
Volume of swimming pool = 650 1/4 yd³
