Answer:
<u>The scale factor is 1.25 and this represents an enlargement.</u>
Step-by-step explanation:
As shown at the figure
The side length of the first hexagon = 5
The side length of the second hexagon = 6.25
So, the scale factor = 6.25/5 = 1.25
and the second hexagon is larger than the first hexagon.
So,
<u>The scale factor is 1.25 and this represents an enlargement.</u>

Answer: $142.80</h3>
==========================================================
Explanation:
To get this answer, we double the 71.40 to get 142.80
You can think of it like an equation and we multiply both sides by 2
4 jeans = 71.40 dollars
2*(4 jeans) = 2*(71.40 dollars)
8 jeans = 142.80 dollars
------------
Or you could solve it like this
(4 jeans)/(71.40 dollars) = (8 jeans)/(x dollars)
4/71.40 = 8/x
4x = 71.40*8
4x = 571.2
x = 571.2/4
x = 142.80
------------
Yet another way to solve is to first find the unit rate
4 jeans cost 71.40, so that must mean 1 pair of jeans cost 71.40/4 = 17.85 dollars. This is the unit rate since "unit" means "one". It's the price per pair of jeans.
Multiply that by 8 to find out how much 8 pairs will cost, and we get 17.85*8 = 142.80
Answer:
Methods including water divining, astrology, numerology, fortune telling, interpretation of dreams, and many other forms of divination, have been used for millennia to attempt to predict the future.
Step-by-step explanation:
hope it helps : )
Subtract 16 to both sides to the equation becomes -2x^2 + 7x + 5 = 0.
To solve this equation, we can make use of the quadratic formula. The quadratic formula solves equations of the form ax^2 + bx + c = 0
x = [ -b ± √(b^2 - 4ac) ] / (2a)
x = [ -7 ± √(7^2 - 4(-2)(5)) ] / ( 2(-2) )
x = [ -7 ± √(49 - (-40) ) ] / ( -4 )
x = [ -7 ± √(89) ] / ( -4)
x = [ -7 ± sqrt(89) ] / ( -4 )
x = 7/4 ± -sqrt(89)/4
The answers are 7/4 + sqrt(89)/4 and 7/4 - sqrt(89)/4.
