Answer:
100.5
Step-by-step explanation:
22/7*2^2*8
=22/7*4*8
=22/7*32
=100.5
Use the formula that states that the sum of the angles of an n-sided polygon is given by
S=(n−2)180
0
........(1)
Since we are given that the two angles are right angles and each of the remaining angles is 144
0
, therefore, the sum is:
S=90
0
+90
0
+(n−2)144
0
.........(2)
Therefore setting (2) equal to (1) we get
(n−2)180
0
=90
0
+90
0
+(n−2)144
0
⇒(n−2)180
0
−(n−2)144
0
=180
0
⇒(n−2)(180
0
−144
0
)=180
0
⇒(n−2)(36
0
)=180
0
⇒n−2=
36
180
⇒n−2=5
⇒n=5+2=7
Hence, the polygon has 7 sides.
So $350 X 10 =$3500
Then, you add the initial $1500,
which means he now has $5000
The difference between $5000 and $4500 is $500,
<span>And $500 is 9% of $4500, </span>
So the deal is equivalent to a yearly interest of 9%
<span>Hope this helps ! :)</span>
Answer:
3648 Freshmen students major in economics.
Step-by-step explanation:
This is done by taking the whole class (4800) and multiply it by the percentage (.76 ((converted to decimal))) to get the amount.
Answer: Cluster sampling
Step-by-step explanation:
Cluster sampling is a type of sampling method . With cluster sampling, the observer splits the population into separate groups which are called as called clusters. After dividing the whole populations into clusters he select a simple random sample of clusters from the population. The observer conducts his analysis on data from the sampled clusters.
From the given statement we can see that the automobile is doing his analysis by selecting three stores from each state (cluster) in the country and surveys all customers present in the store in a certain week.
Hence, he used cluster sampling .
