8/10 is equivalent to 4/5. just divide both 8 and 10 by 2
Common ratio can be found by dividing the 2nd term by the first
r = 48/6
r = 8
an = a1 * r^(n-1)
n = term to find = 8
a1 = first number = 6
r = common ratio = 8
now we sub
a(8) = 6 * 8^(8-1)
a(8) = 6 * 8^7
a(8) = 6 * 2097152
a(8) = 12582912 <==
Answer:
3 in
Step-by-step explanation:
Apparently, we are to assume that the height and width are proportional:
height/width = (6 in)/(8 in) = (new height)/(4 in)
Multiplying by 4 in will tell us the new height:
new height = (4 in)(6/8) = 3 in
The reduced frame will be 3 inches tall.
First of all you need to get rid of the -27 on the left side, to do so you add 27 to both sides so it becomes:
5/8a=20
Now you can divide it by 5 to get:
1/8a=4
Now multiply it by 8 to get:
a=32
Hope this helps :)
