Answer:
n= -14
Step-by-step explanation:
First, convert
into a decimal:
as a decimal is 0.5
now the equation is 0.5n+10.5=3.5
Move the constant to the right and change its sign:
0.5n=3.5-10.5
Calculate the difference:
0.5n=3.5-10.5
0.5n= -7
Divide both sides of the equation by 0.5:
0.5n÷0.5= -7÷0.5
n= -14
Hope this helps!! <3
We are given this explicit formula :

In order to find eighth term let us plug n as 8 in this formula:

subtracting 8-1 first using pemdas rule

multiplying 5 and 7

subtracting 35-6
c(8) = 29
So eighth term is 29.
8/4 should work, because the numerator's higher than the denominator.
Answer:
8835.73ft^3
Step-by-step explanation:
First:
Find area of the base circle.
Diameter is 15, so radius is 7.5
Area of the base circle is 56.25pi (use formula: A=pi(r)^2 ) (also ill convert pi into decimals only later)
next find the volume of the cylinder
height is 40 so volume = 56.25pi*40 = 2250pi
next find the volume of the dome at the top.
you know the radius is 7.5
Use volume of sphere formula below :
4
/3πr^3
=1767.15
alright now add the two bolded values
1767.15+2250pi
= 8835.73
hope this helps
