Answer

diameter=18 cm

radius=18/2=9cm

Area of circle= pi r^2

 = 3.142*(9)^2

 =254.502 cm^2

Area of square= (l)^2

 =(18)^2

 =324 cm^2

Total shaded area= 324-254.502

 =69.498 cm^2

Hope it helps

Area of Ohio ≈ 45,000 square miles

The population density of Ohio is 261.33 people / square miles

<h3>Population Density </h3>

From the question, we are to determine the population density of Ohio

Using the internet,

Population of Ohio = 11,760,000

Area of Ohio = 44,825 square miles

Area of Ohio ≈ 45,000 square miles

Population density is given by the formula,

Population density = Number of people / Land area

Thus,

Population density of Ohio = 11760000/45000

Population density of Ohio = 261.33 people / square miles

Hence, the population density of Ohio is 261.33 people / square miles

(-3j²k³)²(2j²k)³ = When a power is raised to a power the exponents have to be multiplied.

= (-3²j⁽²*²⁾k⁽³*²⁾)(2³j⁽²*³⁾k³) = We can take out the constants

= (9)(8)(j⁴k⁶)(j⁶k³) = We can group the same variables

= 72(j⁴j⁶)(k⁶k³) = When multiplying two powers that have the same base, you have to add the exponents.

= 72 j⁽⁴⁺⁶⁾k⁽⁶⁺³⁾ = 72j¹⁰k⁹

Answer = 72j¹⁰k⁹

Hope this helps!

In order for the mode to be 6, there must be more of them than any other number. In order for the mean to be 3.5, most of the distribution must lie at 3 or below to balance the large number of 6s. For the median to be 3, there must be as many scores at or above 3 as at or below 3. Thus, we choose to have most of the distribution with values 1, 2, 3 and only enough 6s to make that be the mode.

The Country Buffet restaurant has tables that seat 6 people and booths that can seat 4 people. The restaurant has 38 seating uni

Alina [70]

Answer:

There are 20 booths and (38 - 20), or 18, tables

Step-by-step explanation:

Represent the number of tables with t and the number of booths with b.

We need to find the values of t and b.

(6 people/table)(t) + (4 people/booth)b = 188 (units are "people")

t + b = 38 (units are "seating units")

Solving the second equation for t, we get 38 - b = t.

Substitute 38 - b for t in the first equation:

(6 people/table)(38 - b) + (4 people/booth)b = 188

Then solve for b: 6(38) - 6b + 4b = 188, or:

228 - 2b = 188, or 2b = 228 - 188, or 2b = 40. Thus, b = 20 (booths)

There are 20 booths and (38 - 20), or 18, tables.
