Answer:
Step-by-step explanation:
The arithmetic series is
From the given series the general term of the series is
When , we substitute into the general formula to get:
When k=2, we get:
When k=3, we substitute to get:
When k=4, we substitute to get:
When k=5, we get:
A is the correct answer
(to find diagonal of a square , you can get help from Pythagorean Theorem)

Answer:
143cm
Step-by-step explanation:
Area=2(l+b)
Substitute the values for the variables.
66=2(l+22/5)
66=2xl+2x<u>22</u>
5
66=2l+<u>44</u>
5
Cross multiply
66x5=2l+44
330=2l+44
Collect like terms
-2l = 44-330
-2l = -286
<u>-2l </u>=<u> </u><u>-286</u>
-2 -2
l=143
The missing length is 143m.
Answer:
4/25
Step-by-step explanation:
8/10 = 4/5
2/10 = 1/5
We can multiply these 2 events because they do not depend on each other.
1/5* 4/5 = 4/25
