How more feet is the outer perimeter of the walkway than the perimeter of the pool is 48 ft
Since 6ft is the width of walkaway
Hence:
Let increase in width be 12
Let increase in length be 12
Now let determine How many
more feet is the outer perimeter of the walkway than the perimeter of the pool
Outer perimeter Number of feets = 2×(12+12)
Outer perimeter Number of feets = 2×24
Outer perimeter Number of feets = 48 ft
Inconclusion How more feet is the outer perimeter of the walkway than the perimeter of the pool is 48 ft

The perimeter of a rectangle is given by the formula,

We substitute,
and

into the above formula to obtain the expression,


We now group the x and y terms on the Left Hand Side of the equation to get.


We now divide through by 2 to get,

Therefore the width of the rectangle is

The number of participants with laptop is 115 and without laptop is 161
<u>Step-by-step explanation:</u>
Total number of participants= 276
Participants with laptop = (5/12) 276
= 115
Participants without laptop= 276 - 115
= 161
Answer: the tuition in 2020 is $502300
Step-by-step explanation:
The annual tuition at a specific college was $20,500 in 2000, and $45,4120 in 2018. Let us assume that the rate of increase is linear. Therefore, the fees in increasing in an arithmetic progression.
The formula for determining the nth term of an arithmetic sequence is expressed as
Tn = a + (n - 1)d
Where
a represents the first term of the sequence.
d represents the common difference.
n represents the number of terms in the sequence.
From the information given,
a = $20500
The fee in 2018 is the 19th term of the sequence. Therefore,
T19 = $45,4120
n = 19
Therefore,
454120 = 20500 + (19 - 1) d
454120 - 20500 = 19d
18d = 433620
d = 24090
Therefore, an
equation that can be used to find the tuition y for x years after 2000 is
y = 20500 + 24090(x - 1)
Therefore, at 2020,
n = 21
y = 20500 + 24090(21 - 1)
y = 20500 + 481800
y = $502300
