What can you conclude about the population density from table provided
vaieri [72.5K]

The population density of an area is the number of people living in per unit area. The most populated region is Region A.

<h3>What is Population Density?</h3>

The population density of an area is the number of people living in per unit area. It is given by the formula,

\text{Population Density}=\dfrac{\text{Population of the area}}{\text{Total area}}

The population density of the different regions is as follows,

Region A = 20,178 person /521 km² = 38.729 person/km²

Region B = 1,200 person /451 km² = 2.66 person/km²

Region C = 13,475person /395 km² = 34.114 person/km²

Region D = 6,980 person /426 km² = 16.385 person/km²

Hence, The most populated region is Region A.

Ahmad just bought a used sailboat with two sails that need replacing. How much sail fabric will Ahmad need if he replaces sail A
ValentinkaMS [17]

Answer:

sail a = 81ft²

sail b base = 12ft

Step-by-step explanation:

question 5:

the measurements for sail A are 18ft(height) and 9ft (base)

the formula to find the the area of a triangle is (b · h) 1/2

(9 · 18) 1/2 = (162) 1/2 = 81

so ahmad will need 81ft² of fabric for sail a

question 6:

we know that the formula to find the area of a triangle is  (b · h) 1/2 = a, since we know the height and the area of the triangle we plug them into the equation to find the measurement of the base.  

(b · 18) 1/2 = 108

\frac{(b . 18) 1/2}{1/2} = 108/ 1/2

(b · 18) = 216

18b  = 216

18b/18 = 216/18

b= 12

check your work:

(12 · 18) 1/2 = 108

(216) 1/2 = 108

108 = 108  true!

the base measurement for sail b is 12ft

hope this helps and have a great day!!
