4 plus negative 3 is 1.

When adding negative numbers to positive ones, you should treat it as a normal subtraction, so 4-3.

4 + -3 = 1

The reason being is the three is negative and the four is positive.  So when you take a positive number and subtract it from a negative number - you get the difference of the two, the solution being one.

Circle towns limit form a perfectly circular shape that has a population of 20000 in the population density of 480 people per sq
Alex

Answer:

D =\frac{P}{\pi X^2}

And solving for the radius we got:

X = \sqrt{\frac{P}{\pi D}}

And replacing the data given we got:

X = \sqrt{\frac{480 \frac{people}{km^2}}{\pi *20000 people}}= 0.0874Km

And this value converted to meters is X = 87.40 m

Step-by-step explanation:

For this case we know the population size P = 20000 and we also know the population density D = 480 \frac{people}{km^2}

We can assume that the area is a circle. We also know that the formula for the population density is given by:

D= \frac{P}{A}

Where P represent the number of people and A the area. Since we are assuming a circle then the area is given by:

A = \pi X^2

With X the radius of the circle

And then the populationd density become:

D =\frac{P}{\pi X^2}

And solving for the radius we got:

X = \sqrt{\frac{P}{\pi D}}

And replacing the data given we got:

X = \sqrt{\frac{480 \frac{people}{km^2}}{\pi *20000 people}}= 0.0874Km

And this value converted to meters is X = 87.40 m

Parallelogram PARL is similar to parallelogram WXYZ. If AP = 25, PL = 29, and WZ = 145, find the value of c.
joja [24]

Answer:

The correct answer is 56

Step-by-step explanation:

Parallelogram PARL is similar to parallelogram WXYZ. If AP = 14, PL = 25, and WZ = 100, find the value of c.

100=25*4, so the other side must be also multiplicated by 4 ansd 14*4=56

A slow pitch softball diamond is actually a square 60 ft on a side. how far is it from home to second ​base?
krek1111 [17]
For this case we have a square whose sides are known and equal to 60 ft.
 We want to find the diagonal of the square.
 For this, we use the Pythagorean theorem.
 We have then:
 d^2 = 60^2 + 60^2&#10;&#10;d =  \sqrt{60^2 + 60^2}&#10;&#10; d =  \sqrt{3600 + 3600}&#10;&#10;d = \sqrt{2*3600}&#10;&#10;d = 60\sqrt{2}&#10;
 Answer:
 
from home to second ​base it is about:
 d = 60\sqrt{2} feet
