The delivery radius which will allow the pizza restaurant to deliver to approximately 20,000 people is 2. 5 miles

<h3>What is population density?</h3>

Population density can be defined as the number of individuals within a species in a specific geographic area.

The formula for population density is expressed as;

Population density = Number of people/Land area

Where;

  • Number of people = 20000
  • Population density = 1000

Land area = 20000/ 1000

Land area = 20 square miles

But ;

Area = πr²

Substitute the value of area in the formula

20 = 3. 142 × r²

r² = 20/ 3. 142

r² = 6. 37

r  = √6. 37

r = 2. 5 miles

Thus, the delivery radius which will allow the pizza restaurant to deliver to approximately 20,000 people is 2. 5 miles

Prove by factorization √16×81=√16×√81
Oksanka [162]

Answer:

√16×81 = 4×9 or √1296 = 36

√16×√81 = 4×9 = 36

Step-by-step explanation:

√81×16

We simplify 81 and 16 by prime factorisation (expressing a number as a product of its prime factors).

√81 = √3×3×3×3 = √9×9 = √9² = 9

√16 = √2×2×2×2 = √4×4 = √4² = 4

A researcher determines that the number of bacteria increase at a rate modeled by =25*2^x. What is the growth rate?
dolphi86 [110]

Answer:

100%

Step-by-step explanation:

An exponential equation with a growth rate can be expressed as: f(x)=A(1+r)^x where r is a positive number, and represents the growth rate.

In this case since the base of the exponent equals 2, that means r=1, since 1+1=2. This means it has a growth rate of 100%, which makes sense, since the base is 2, meaning it doubles or increases by 100% every time x increases by 1.

allowing 20% discount on the marked price of a watch the value of the watch will be Rs 6328 when a vat 13%is added ,find the fin
Ahat [919]

Step-by-step explanation:

Let the marked price of a watch be =₹x

∴ Discount price = x- 20% of x

= x - 0.2x

=0.8x

Amount of VAT = 13% of 0.8x

0.13 x 0.8x

0.104x

Now,

Selling price = 0.8x + 0.104x

              ∴6328 = 0.904x

x = 0.904 / 6328

x=0.00014285714
