The area of a rectangular city park is 25/54 square miles. The length of the park is 5/9 mile. What is th width, in miles, of th

wolverine [178]

Answer:

0.833 miles

Step-by-step explanation:

Because you know the area, you can use the formula for area of a rectangle. Just plug in what you know and solve.

$\frac{25}{54} = \frac{30}{54}w$

30/54 is the same as 5/9.

$(\frac{25}{54})54 = (\frac{30}{54}w)54$

Multiply by its denominator.

$25=30w$

Simplify

$25/30=30w/30$

Divide by 30

$w=\frac{5}{6}$

5/6 is roughly 0.833

navik [9.2K]

Answer:

A = 31.8 cm2

Step-by-step explanation:

Yhe formula:

$A=\frac{\pi r^{2}(Central.Angle) }{360}$

$r=18/2=9cm$

central angle = (180-135)° = 45°

$A=\frac{\pi ((9)^{2}(45) }{360} = \frac{\pi (81)(45)}{360} = 10.125\pi cm^{2}$

$A=31.8cm^{2}$

Using Eulers formula, how many edges does a polyhedron with 9 faces and 14 vertices have?

qwelly [4]

<h3>By Euler's Formula </h3>

F + V = E + 2

<h2><u>Solution</u></h2>

F = 9

V = 14

E = ?

<h3>Substuting the values</h3>

⇨ 9 + 14 = E + 2

⇨ 23 = E + 2

⇨ 23 - 2 = E

⇨ 21 = E

Hence , the number of edges in polyhedron is 21.
