The perimeter of a rectangular pool is 72 meters. If the length of the pool is twice its breadth. Its length is_________.
1 answer:
Answer:
Length = 18 meters
Step-by-step explanation:
Let the length of the rectangular pool = l meters
And breadth of the pool = w meters
Perimeter of the rectangular pool = 2(l + 2w)
Since, perimeter of the rectangular pool is 72 meters.
2(l + 2w) = 72
l + 2w = 36 --------(1)
If length of the pool is twice of its breadth,
l = 2w
w = -------(2)
By substituting the value of 'w' from equation (2) to equation (1),
2l = 36
l = 18 meters

Answer:
Figure 2 and 3
Step-by-step explanation:
This question is incomplete, please find the figures in the attachment.
Number of cans of beans bought by Emery = 3
Total weight of cans = 2.4 pounds
weight of each can = = 0.8 pounds
If x be the number of cans and y represents the total weight then the model for this situation will be
y = 0.8x
Figure 1 :
From this graph weight of each can = pounds
so this graph is not the correct choice.
Figure 2:
From this graph weight of each can = = 0.8 pounds
So this graph is the correct choice.
Figure 3 :
From the given table, weight of each can = pounds
So the table shows the relationship.
Figure 4 :
From the given table, weight of each can = = 1.25 pounds
so this table is not the correct choice.
Therefore, figure 2 and 3 is illustrate the relationship.
