Answer:
nth term = 
Step-by-step explanation:
Let us assume that the given sequence is a G.P.
Now, if the first term of the G.P. is a and the common ratio is r, then
Third term =
.......... (1) and
20th term =
........... (2)
Now, dividing equation (2) with equation (1) we get
⇒
⇒ r = 1.2.
Hence, from equation (1) we get
a(1.2)² = 11
⇒ a = 7.639 (Approx.)
Therefore, the general term of the sequence i.e. nth term =
(Answer)
Answer:
896 inch^3
STAY SAFE, GOD BLESS YOU :)
Step-by-step explanation:
V = l x w x h
= 19 x 2 x 7
= 266 inch^3
= 6 x 15 x 7
= 630 inch^3
Add them both
= 630 + 266
= 896 inch^3
X^2-4x=-2x+24
x^2-2x=24
x^2-2x-24=0
(x-6)(x+4)
Proof:
-6+4=-2
-6*4=-24
Final answer: (x-6)(x+4)
Answer:
6 : 5
Step-by-step explanation:
Rate = 
But Rate is also equal to number of lawns mowed in a certain amount of time.
Since ratio should always be in terms of simple whole numbers.
If 6/5 lawns are mowed in 1 hour, then,
6 lawns will be mowed in:
=
= 5 hours.
therefore, 6 laws will be mowed in 5 hours.
Ratio of lawns to hours in 6:5
