<h3>
Answer: 180 inches</h3>
Work Shown:
L = 54 = length
W = 36 = width
P = 2(L+W) ... perimeter of the rectangle
P = 2(54+36)
P = 2(90)
P = 180
She needs 180 inches of ribbon.
To convert to feet, divide by 12. So 180 inches = 180/12 = 15 feet.
this is an arithmetic sequence because the difference between each number is 5
formula :
an = a1 + d(n-1)
an = -26 + (-5) (n-1)
an = -26 -5n +5
an = 5n -21 is the answer
A percent can be viewed as a fraction over 100, so in this case, we form the fraction 80/100.
However, this is not in simplest form. The largest number that goes into both of these (greatest common factor) is 20, so we should divide the numerator and denominator by 20.
When we do this, we can see that the simplest fraction to represent 80% is 4/5.
Answer:
See below
Step-by-step explanation:
A 2.5 % decrease means 97.5 % remains (.975)
population = 10800 ( .975) ^n where n = years past 2002
in 2020 n = 18
10800 (.975)^18 = 6847 people
