Hi there,
So the problem is 2/7 ÷ 1/3
well the answer to this is 6/7
In order to solve this is to cross multiply so
2 x 3 and 7x3
which is the result of 6/7
In decimal form it is: 0.857
Hope this is correct :)
Have a great day
Answer:
172.27 in
Step-by-step explanation:
Apply the Sine Rule
Sine Rule is given as:

c = x = ?
C = 180 - (52 + 48) = 80° (sum of triangle)
b = 130 in.
B = 48°
Plug in the values

Multiply both sides by sin(80)

172.274641 = x
x = 172.27 in. (to 2 decimal places)
Answer:
8th term of geometric sequence is 312500
Step-by-step explanation:
Given :
and common ratio (r) = 5
We have to find the 8th term of the geometric sequence whose
and common ratio (r) = 5
Geometric sequence is a sequence of numbers in which next term is found by multiplying by a constant called the common ratio (r).
......(1)
where
is nth term and a is first term.
For given sequence
a can be find using
and r = 5
Substitute in (1) , we get,
Thus, 8th term of the sequence denoted as 
Substitute n= 8 in (1) , we get,

Thus 8th term of geometric sequence is 312500

Answer:
(b) 5, 17
Step-by-step explanation:
You can try the answer choices easily enough.
2 +3×8 ≠ 14
2 +3×5 = 17 . . . . this choice works (5, 17)
2 +3×2 ≠ 20
2 +3×4 ≠ 18
2 +3×10 ≠ 12
__
Or, you can solve the equation:
x + (2 +3x) = 22
4x = 20 . . . . . . . . subtract 2
x = 5 . . . . . . . . . . divide by 4
The numbers are 5 and (22 -5) = 17.
