Answer:
b = 1.52
Step-by-step explanation:
Length of diagonals of a parallelogram =
and 
If the given parallelogram is a rectangle,
Length of the diagonals will be equal in measure,
Therefore, 
245b - 365 = 
245b - 365 = 
5(245b - 365) = 4(3b + 6)
1225b - 1825 = 12b + 24
1225b - 12b = 24 + 1825
1213b = 1849
b = 
b = 1.52
The shortcut is the hypotenuse of a right triangle with legs 6 and 8, so 6²+8²=c²
36+64=c
100=c²
c=10.
so he traveled 6+8+10=24km
Start with the first sentence, and the definition of the area of a rectangle:
l * w = 36
Rewrite the equation to get
l = 36 / w
or
w = 36 / l
Either one shows the inverse relationship between w and l.
Assuming the last part wants you to write an equation for an x-y graph, the equation would be
y = 36 / x
100% of Kerion's paper squares are:
(100% / 100%) = 1
Half of the squares of your paper are colored blue:
(1) / (2) = 1/2
Of the blue squares, 1/3 of them will also have stripes:
(1/2) * (1/3) = 1/6
answer
A fraction of (1/6) squares will be blue with strips
