The question is incomplete. The complete question is :

A map of the Orchid Hill Neighborhood is shown. The population of Orchid Hill Neighborhood is 360 people. The length of each block is the same and the length of 20 blocks is 1 mile.

a). What is the area in square miles of Orchard Hill?

b). What is the population density of the Orchard Hill Neighborhood, given as a number of people per square mile?

Solution :

It is given that :

The total population of Orchid Hill Neighborhood is = 360

The length of 20 blocks = 1 mile

So, 20 blocks = 1 mile

∴ $1 \text{ block} = \frac{1}{20} \text{ mile}$

= 0.05 mile

So the length of the neighborhood is = 4 x 0.05

= 0.20 mile

The width of the neighborhood is = 3 x 0.05

= 0.15 mile

a). Therefore, the area of the Orchid Hill Neighborhood in square miles is

A = length x width

= 0.20 x 0.15

= 0.03 square miles

b). Population density is defined as the number of people living in an unit area.

i.e. $\frac{360}{0.03}$

= 12,000 people per square mile

Answer from: Quest

no, the equation would be invalid since they are both not equal.

step-by-step explanation:

here you got

4y-6+4y 2-9

first, you would simplify the equation on the form.

4y-6+4y 2-9

then, move all the terms that contains a y to the left and all the other terms to the right.

+4y-4y+-9-6

finally, you will simplify the left and the right side of the equation.

y=-3

Okay so for every triangle has three angles that always add up to 180 degrees. and to tell the difference between whether they are secure, right or obtuse is that acute: has one angle that is less than 90 degrees. right triangle means there is at least one angle that is exactly 90 degrees. and an obtuse angle has an angle that is bigger than 180 degrees. i’ll do #13 as an example: 13. 40 and 50 so if every triangle has 180 degrees 40+50= 90 degrees then180-90= 90 degrees so the third angle is 90 degrees and because this triangle has a 90 degree angle it means it is a right triangle

Kayla wants to find the width, ab, of a river. she walks along the edge of the river 65 ft and marks point c. then she walks 25 ft further and marks point d. she turns 90° and walks until her location, point a, and point c are collinear. she marks point e at this location, as shown. (a) can kayla conclude that δ and δ are similar? why or why not? (b) suppose de = 15 ft. what can kayla conclude about the width of the river?
