Answer:
To determine the common ratio of a geometric sequence. You just need to divide any two consecutive terms on it. You can see below that all of them have the same quotient.
1.2 / 1.5 = 0.8
0.96 / 1.2 = 0.8
0.768 / 0.96 = 0.8
.
Decimal form = 0.8
Fraction form = 4/5
.
Check:
1.5 x 0.8 = 1.2
1.5 x 4/5 = 6/5 = 1 1/5 = 1.2
Therefore, the common ratio between successive terms in the sequence? 1.5, 1.2, 0.96, 0.768 is 0.8 or 4/5.
Answer:
YESSSSS I AM APART OF THE KENMA CULT
Step-by-step explanation:
First of all move all the Xs to the left side, and the numbers to the left.
So
x/2-x = -13
Which means
X/2-x/1 = -13
Which means x/2-2x/2 = -13
So u combine to two fractions
-x/2 = -13
-x = -13 * 2
Which means x = 26 (u flip the negativity)
Answer:
20 ft
Step-by-step explanation:
Given;
Length of flagpole shadow = 30 ft
Sign post height = 4 ft
Length of sign post shadow = 6 ft
Since the two objects are close to each other (the same location)
The height and shadow length of the two objects follows the same ratio, just like similar triangles;
Using the Ratio or similar triangles Formula;
height of flagpole/flagpole shadow length = height of sign post/ sign post shadow length
Substituting the values;
h/30 = 4/6
h = 4/6 × 30 = 20 ft
Flagpole height = 20 ft
