Answer: A) 18

Step-by-step explanation: Let's subtract 59.87 - 42.1....

59.87 - 42.1 = 17.7

As you can see there no options representing 17.7, therefore, we have to round it up the nearest ones.

17.7 rounded to the nearest ones is 18.

I hope this helps!

No, the number of children are not proportional. In one household where there is 1 parent, there are 3 children, and in another household where there is 1 parent, there are 5 children. The numbers are not consistent, and therefore not proportional.

Find the area of a regular pentagon with apothem length of about 10.3 meters. Round to the nearest tenth if necessary.
matrenka [14]

Answer:

The area = 182.52 sq units.

Step-by-step explanation:

  1. Area of regular polygon can be found by splitting into smaller triangles.
  2. Each triangle has base as side of polygon and vertex as center of polygon.

now consider ΔOAB,

we know ∠AOB = \frac{360}{5}° =72°

<h3>     (this is due to symmetry)</h3>

as  ∠AOD = (∠AOB)/2 = 36°

Now we know AD=AB/2 =\frac{10.3}{2} =5.15 m

using trignometric relation tan(∠AOD) =\frac{AD}{OD}

⇒OD = \frac{AD}{tan(36)} = \frac{5.15}{tan(36)}

AREA OF TRIANGLE = BASE × HEIGHT /2

area of ΔOAD = \frac{1}{2} × 5.15 × \frac{5.15}{tan(36)}

     = \frac{(5.15)^2}{2tan(36)}

<u>As there are 10 such triangles like </u>ΔOAD

Total area =10×\frac{(5.15)^2}{2tan(36)}

 = 182.525447428574
