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)
Answer:
4/9
Step-by-step explanation:
Given rate is 1/3 acre per 3/4 hours.
To calculate the rate per hour, we have to divide total acres by the fraction of hour
=> 
=> 
=> 4/9
Answer:
First operation is Parathenses or Grouping. In this case, you need to use distrubtion to go past this operation
Step-by-step explanation:
Answer:
1.
$.33
$3
2.
all the answers can be found when the rate is known which is
grapes are sold at $3 per pound
Step-by-step explanation:
$6 ÷ 2 pounds = $3 per 1 pound
this means 1 pound of grapes is $3
next row
1 ÷ 3 = $.33
3rd row
1 multiplied by 3 = $3
2.
all the answers can be found when the rate is known which is
grapes are sold at $3 per pound
Using the distance formula:
Distance = √((x2-x1)^2 + (y2-y1)^2)
Distance = √((5-2)^2 + (-8 - -4)^2
Distance = √(3^2 + -4^2)
Distance = √(9 +16)
Distance = √25
Distance = 5
