Answer:
You first draw a sketch of it
then you say half Base × height
22m×26m = 572 square metres
22m×23.6m = 519.2square metres
572 square meters × 4 = 2288 square meters
2288 square meters + 519.2 square meters =2807.2
what I think
Answer:
Number of children = 386
Number of adults = 287
Step-by-step explanation:
Let
x = number of children
y = number of adults
x + y = 673 (1)
1.75x + 2y = 1249.50 (2)
From (1)
x = 673 - y
Substitute x = 673 - y into (2)
1.75x + 2y = 1249.50
1.75(673 - y) + 2y = 1249.50
1177.75 - 1.75y + 2y = 1249.50
- 1.75y + 2y = 1249.50 - 1177.75
0.25y = 71.75
y = 71.75/0.25
y = 287
Substitute y = 287 into (1)
x + y = 673
x + 287 = 673
x = 673 - 287
x = 386
Number of children = 386
Number of adults = 287
Answer:
Sequence : ![a_n=8(\frac{1}{2})^{n-1}](https://tex.z-dn.net/?f=a_n%3D8%28%5Cfrac%7B1%7D%7B2%7D%29%5E%7Bn-1%7D)
Rate of change : -3
Step-by-step explanation:
It is given that the sequence represents by the points (1,8), (2,4), (4,1) and (5,0.5).
We know that the
represent the point (n,k). So, we have
It is clear that the above sequence is a geometric sequence because it has common ratio
.
First term :
Common ratio :
The nth term of a G.P. is
Therefore, the required sequence is
.
We need to find the average rate of change from n = 1 to n = 3.
Therefore, the average rate of change from n = 1 to n = 3 is -3.
