Answer:
-5
Step-by-step explanation:
Geometric sequences have common ratios.
You can see if a sequence is geometric by computing:
.
If you get the same result per consecutive pair, then there is a common ratio and the sequence is geometric.
Let's see:
So if this equations holds (if all 3 fractions equal the same thing), then is geometric and we have also have computed the common ratio.
The first fraction results in -250/50=-5.
The second fraction results in 50/-10=-5.
The third fraction results in -10/2=-5.
All three fractions are equal and so the equation holds so it is geometric and the common ratio is -5.
<u><em>Answer:</em></u>
Exact volume = 294π in³
Approximate volume = 923.6 in³
<u><em>Explanation:</em></u>
<u>The volume of a cylinder can be calculated using the following rule:</u>
volume = πr²h
where r is the radius and h is the height of the cylinder
<u>In the given cylinder:</u>
radius = r = 7 in
height = h = 6 in
<u>Substitute with the givens in the formula to get the volume:</u>
Volume of cylinder = πr²h = π(7)²(6) = 294π in³ ≈ 923.6 in³ to the nearest tenth
Hope this helps :)
Answer:
37.625 square yards or 37⅝ square yards
Step-by-step explanation:
Area of the triangle = ½*base*height
Where,
base = 10¾ yd = 10.75 yds
height = 7 yds
Substitute the value of each variable into the equation:
Area = ½*10.75*7
Area = 37.625 square yards or 37⅝ square yards
Answer:
-9
Step-by-step explanation:
the first number
hope it is well understood
N(20/100)(20/100)=20
n(1/5)(1/5)=20
n/25=20
n=500
