Answer:
Arithmetic sequence
Step-by-step explanation:
A sequence is described as an arithmetic sequence when there is a common difference between the numbers
A sequence is a geometric sequence when there is a common ratio between the numbers
12,10,8
10-12= -2
8-10= -2
10/12= 0.83
8/10= 0.8
Hence the sequence is an arithmetic sequence with a common difference of -2
Answer:
volume of a hemisphere ≈ 36369.5 in³
Step-by-step explanation:
To find the formula for calculating the volume of a hemisphere, we will follow the steps below:
write the formula for calculating the volume of a hemisphere.
volume of a hemisphere = volume of a sphere ÷2
=
πr³ ÷ 2
=
πr³
where r is the radius
from the question given, diameter = 51.8 inches
but diameter = 2r , this implies that r =
hence r =
= 25.9 inches
π is a constant and is ≈ 3.14
we can now proceed to insert the values into the formula
volume of a hemisphere =
πr³
=
× 3.14 ×25.9³
=
× 3.14×17373.979
≈36369.5 in³ to the nearest tenth cubic inch.
volume of a hemisphere ≈ 36369.5 in³
Answer:
The reduced dimensions are:
Width = 12 cm
Length = 7.2 cm
Step-by-step explanation:
Original dimensions of Image:
Width = 20 cm
Length = 12 cm
Fran reduced the dimensions using a scale factor of 0.6
We need yo find dimensions of reduction.
We would multiply the original dimensions by 0.6 to find the new dimensions.
So, Width = 20 * 0.6 = 12
length = 12 * 0.6 = 7.2
So, the reduced dimensions are:
Width = 12 cm
Length = 7.2 cm
