EXPLANATION:
Required;
We are required to identify which solid can be formed from discs alone by using the pilling method.
Step-by-step explanation;
If we take several discs of the same radius and begin pilling them one on top of another, we would end up with a cylinder.
Also, if we take several discs which are of decreasing radii, then pilling them one on top of another (starting with the largest to the smallest radius), we would end up with a cone whose shape would be such that the disc with the largest radius would be at the base while the one with the smallest radius would be at the top.
Note however, that this cone would not have a vertex, because the vertex cannot be a circular disc.
Therefore,
ANSWER:
B; Cylinder
E: Cone (not including the vertex)
Evaluate the Function the answer is 34
If it was 25% off, then she paid 75% for it
75% of the original price is 170
0.75x = 170
x = 170 / 0.75
x = 226.67 <== original price
Divide 252 by 21.
21 times 12 = 252
12 is 9 units shorter than 21.
so the answer is 12 inches by 21 inches
you work backwards from the area
area = width times length
a = wl
we know w is 9 units shorter than the length
so now we have the equation 252=(l-9) times l
plug in 21 for l and then solve there is your answer.
Answer:
The required expression is (x+2).
Step-by-step explanation:
The given point is (3,6).
Here,
x-coordinate = 3
y-coordinate = 6
We need to find an algebraic expression to represent the new x-coordinate after a translation of two yards east.
If a point is shift 2 yard east it means the value of x-coordinate increases by 2 units. It means
where, x' is new x-coordinate and x is initial x-coordinate.
Put x=3 in the above equation.
Therefore, the new x-coordinate is 5.
