We'll let x be the shortest side since it's used in both comparisons.
x + 2x + (x+26) = 178
With that equation you should be able to simplify and get each. If you have any questions about how I got that feel free to ask.

Write the first five terms of the arithmetic sequence. a1 = 9; d = -2
asambeis [7]

Answer:

nth term = 1 1/2n -1

Step-by-step explanation:

The arithmetic sequence formula is:

a n = a 1 + ( n – 1 ) d

Where: a n

is the nth term in the sequence

a 1

is the first term in the sequence

n

is the term you are solving for

d

is the common difference for any pair of consecutive numbers in the sequence.

First Term or  

n = 1 :

This is given in the problem.

a 1  =  9

Second Term or  

n = 2 :

Substitute  

2  for  n

in the formula and substitute the values from the problem giving:

a 2 = 9 + ( ( 2 – 1 ) × -2 )

a 2 = 9 + ( 1 × -2 )

a 2 = 9 +-2

a 2 = 7

Fifth Term or  n = 5 :

Substitute      in the formula and substitute the values from the problem giving:

a 5 = 9+ ( ( 5– 1 ) × -2 )

a 5 = 9 + ( 4 × -2 )

a 2 = 9 + -8

a 2 = 1  

Using this same process you should be able to determiner the

Third Term or  n = 3

: and Fourth Term or  n = 4 :

Step-by-step explanation:

So first we set it up:

18ft is 100% of the original

and the area of the copies are 70%

Copies: x

x/70 = 18/100

70(18) = 1260

1260/100 = 12.6

x = 12.6

Answer:

Height of second Bungee jump is 150 feet.

Step-by-step explanation:

Let the height of second jump be x

Now By given details;

Height of first Bungee jump = 200 feet

Also,

first bungee jump is 50 feet higher than your second jump.

Hence,

Height of first jump = 50 + height of second jump

Substituting the values we get;

200=50+x\\x=200-50\\x= 150 ft

Hence the Height of second Bungee jump is 150 feet.
