What is the height of this cone?
Answers
Answer:
height is = 3/2 ft
Step-by-step explanation:
a cones volume can be represented by 1/3(h)(pi)(r^2)
we must go backwards to find this question out
if the diameter is 2/3 then the radius is 1/3
then you must square that
that is 1/3 * 1/3 which is 1/9
1/9(1/3)(pi)(h) is 1/18(pi)
we can remove pi from both sides and multiply the 1/9 and the 1/3
1/27(h) = 1/18
we must find the lcm or least common multiple to figure this out
the lcm is 54
1/27 is essentially 2/54 and 1/18 is 3/54
2/54(h) = 3/54
we can multiply each side by 54
2h = 3
divide 2 on both sides
h is 3/2

Answers
Answer
D.25x2 – 36
Explanation
A. x² – 16x + 64
product = 64
sum = -16
factors: -8 and -8
x² – 16x + 64 = x² - 8x - 8x + 64
= x(x - 8) - 8(x - 8)
= (x - 8)(x-8) = (x-8)² ⇒ Not a difference of squares
B.x² + 4 = (x² + 2²) ⇒ Not a difference of squares
C.9x² – x – 36
product = - 324
sum = -1
Factors: none
9x² – x – 36 ⇒ Has no perfect roots.
D.25x² – 36
25x² – 36 = (5x)² - 6² ⇒ This is the difference of squares.
Answer D
25x²-36=(5x)²-6²

Answer:
The equation is:
Where x is the amount of points needed to tie the record
Step-by-step explanation:
In order to write the equation, we must have to understand the paragraph to find the known facts, the information that we want to find (unknown data) and the relation between them
Known facts:
- Player scored points: 56
- Team record points: 72
Unknown data:
- How many more points the player needs to tie the record?
This unknown data is named as x (the variable to find)
In order to find the relation between known facts and unknown data, we analyze the paragraph:
According to the text, x is the amount of point that the player have to add to his current score (56) to tie the team record (72).
This analysis can be summarized in this sentence: "x plus 56 points must be equal to76 points"
Finally the equation is:
the reason that i think its wrong is that you have nothing after the equils exept for the answer
