Answer:
65/100
Step-by-step explanation:
Since it is a whole percentage it would be over 100. Since its 65%, it would be 65/100
Answer:
The second term of the sequence is T(2) = 6.
Step-by-step explanation:
Here, the first term is given as
T(1) = 2
The general Formula for nth term is given as:
T(n + 1) = 3(T(n))
Now, here the second term
for, n = 1
T(1+1) = 3 (T(1))
or, T(2) = 3 T(1)
⇒ T(2) = 3 x 2 = 6
Hence, the second term of the sequence is T(2) = 6.
Answer:
$44.19
Step-by-step explanation:
15.98-1.25=14.73
14.73*3-44.19
Answer:
Equations
Step-by-step explanation:
16:
7 · (-3) = -21
-3 · 7 = -21
-21 ÷ 7 = -3
-21 ÷ (-3) = 7
17:
-4 · (-5) = 20
-5 · (-4) = 20
20 ÷ (-4) = -5
20 ÷ (-5) = -4
18:
1.5 · (-3) = -4.5
-3 · 1.5 = -4.5
-4.5 ÷ 1.5 = -3
-4.5 ÷ (-3) = 1.5
This is 7th grade?
Hope I helped :)
We have that
[3/2,3/8,3/32,3/128,3/512]
the sum of the geometric sequence is [3/2+3/8+3/32+3/128+3/512]
=(1/512)*[256*3+64*3+16*3+4*3]
=(3/512)*[256+64+16+4]
=(3/512)*[340]
=(1020/512)
=255/128---------> 1.9922
the answer is
1.9922
another way to calculate it
<span>is through the following formula
</span>∑=ao*[(1-r<span>^n)/(1-r)]
</span>
where
ao---------> is the first term
r----------> is the common ratio<span> between terms
n----------> </span><span>is the number of terms
ao=1.5
r=1/4-----> 0.25
n=5
so
</span>∑=1.5*[(1-0.25^5)/(1-0.25)]-------------> 1.99
