16/20. We reduce that and get 4/5.
After this it's much simpler to chage it.
100 dividied by 5 is 20. (20,40,60,80,100)
So the 4th number (4/100)
is 80. 80%.
20% she didn't and 80% she did :) (100-80)
Answer:
270 ft^2
Step-by-step explanation:
find the area of each side
top: 13x7=91
triangle shaped sides(both together): 12x5=60
tiny vertical side: 7x5=35
bottom: 12x7=84
add them all together to get the total surface area is 270ft^2
Hope this helps! :)
Answer:
the first oe
Step-by-step explanation:
Answers:
The second term is 2
The fifth term is 23
The ninth term is 51
-----------------------------------------------------------
Explanation:
To find the second term, replace every n with 2 and use PEMDAS to simplify
a(n) = -5+(n-1)(7)
a(2) = -5+(2-1)(7)
a(2) = -5+(1)(7)
a(2) = -5+7
a(2) = 2
The second term is 2
Similarly, plug in n = 5 to get the fifth term
a(n) = -5+(n-1)(7)
a(5) = -5+(5-1)(7)
a(5) = -5+(4)(7)
a(5) = -5+28
a(5) = 23
The fifth term is 23
Finally, replace every n with 9 to find the ninth term
a(n) = -5+(n-1)(7)
a(9) = -5+(9-1)(7)
a(9) = -5+(8)(7)
a(9) = -5+56
a(9) = 51
The ninth term is 51
Answer: 7.63
9 percent of 7 is 0.63
7+0.63= 7.63
