Answer:
Step-by-step explanation:
The sequence is arithmetic because it is going down/up by the same number each time.
It is going down by 6.
This tells us that the common difference is -6.
The first term is 30.
The following is the explicit form of an arithmetic sequence:
where 
is the first term and 
is the common difference.
So we have 
and 
.
Plugging this information into our explicit formula:
Let's check it.
The first term is :
which is what the pattern reads for the first term.
The second term is 
:
which is what the pattern reads for the second term.
The third term is 
:
which is what the pattern reads for the third term.
The fourth term is 
:
which is what the pattern reads for the fourth term.
This rule certainly does generate the terms of our sequence as we have shown above.
The explicit form with no doubt is .
A little over 2,000 steps would be 1 mile.
It really counts on the length of you stride.
Answer:
Step-by-step explanation:
<em>Rule need to remember to solve such questions</em><em>:</em>
There were 5000 mangoes in the basket, 3750 of them were good.
% mangoes
25% ---------- 1250
75% ----------- X
25x = 1250.75
25x = 93750
X = 93750/25
X = 3750 mangoes
3750+1250 = 5000
Answer:
37
Step-by-step explanation:
The cosine of an angle is the length of the adjacent side, in this case x, divided by the length of the hypotenuse, in this case 85. So you can set up the following equation:
units
