Luiza delivers newspapers in her neighborhood. If you plot the points (−1, 1), (4, 1), (4, −2) and (−1, −2), you will create a r
epresentation of the route she takes, in miles. How many miles does her route cover?

The first thing to do in this case is to draw the ordered pairs in the Cartesian plane and join the points.
We have then that the resulting figure is a rectangle.
We must find the perimeter of the rectangle that is given by:
P = 2L + 2W
Where,
L: long
W: width
Restoring the values:
P = 2 * (5) + 2 * (3)
P = 16
Answer:
her route cover 16 miles.

Answer: 11.5
Step-by-step explanation:
The formula for finding area of triangle is given by :
Area = x base x height
From the question :
Area = 80.5
base = 14
height = ?
substituting into the formula , we have
80.5 = x 14 x height
80.5 = 7x height
divide through by 7 , that is
height = 80 . 5 / 7
height = 11.5
We can borrow from what we know about cylindrical coordinates to set
where . Then we can let
with .
Using proportions, it is found that 7% of the population has blue eyes without blonde hair.
10% of the population has blue eyes. These 10% are composed by:
- 75% of 4%(have blonde hair).
- x% of 96%(do not have blonde hair)
Hence, the relation according to the proportion of 10% is:
Out of the entire population:
0.0729(0.96) = 0.07
7% of the population has blue eyes without blonde hair.
