Answer:

320m

Step-by-step explanation

a rectangle has four sides, two pairs of identical sides. So two sides are 16. So that adds up to 32. Perimeter is all sides added together. so it has to add up to 72. 72 minus 32 is 40, so two of the sides have to be 40. Area is length times width, so 16 times 20, which is 320.

The population of Stark county this year is 7,921 people. Last year the population was 7,547 people. Find the approximate percen

Sholpan [36]

Answer:

Option (C)

Step-by-step explanation:

To determine the population we use the formula,

$P_n=P_0(1+r)^{n}$

Where $P_n$ = final population

$P_0$ = Initial population

r = percentage growth

Now we substitute these values in the formula,

$7921=7547(1+r)^1$

$\frac{7921}{7547}=(1+r)$

r = 1.0496 - 1

r = 0.0496

r = 0.05

Therefore, percentage growth of the population of Stark county is 5%.

Option (C). will be the answer.

A distance of 30 miles on a map is represented by a 2-inch line. If the map is enlarged to 3 times its size, what will be the sc

vichka [17]

Answer:

$\frac{1}{5}\frac{in}{miles}$

Step-by-step explanation:

we know that

The original scale of the map is

$\frac{2}{30}\frac{in}{miles}=\frac{1}{15}\frac{in}{miles}$

If the map is enlarged to 3 times its size

then

the new scale will be

$\frac{2*3}{30}\frac{in}{miles}=\frac{6}{30}=\frac{1}{5}\frac{in}{miles}$

seraphim [82]

Answer:

The given value is discrete variable.

Step-by-step explanation:

Discrete Variable:

Discrete Variable are those variables that can only take on a finite number of values are called "discrete variables." All qualitative variables are discrete. Some quantitative variables are discrete, such as performance rated as 1,2,3,4, or 5, or temperature rounded to the nearest degree.

A silo is in the shape of a cone. The silo is 7 meters tall, and its base has a radius of 1.5 meters. Rice costs 204$ per cubic

olganol [36]

Answer:

$3364.65

Step-by-step explanation:

The volume of the cone is given by the formula ...

V = (1/3)πr²h

Filling in the given numbers, we find the volume to be ...

V = (1/3)π(1.5 m)²(7 m) = 5.25π m³ ≈ 16.49336 m³

The cost of the rice will be the product of this volume and the price per cubic meter:

cost = (16.49336 m³)($204/m³) = $3364.65

The cost of the rice necessary to fill the volume is $3364.65.

<em>Comment on pi</em>

If you use the value 3.14 for pi, the cost comes to $3362.94. A 3-digit value of pi only gives an answer good in its first 3 digits.
