A plane has fees for 420 passengers 15% of the seats are empty how many passengers are on the plane

serious [3.7K]

Answer:

357 passengers

Step-by-step explanation:

$\frac{x}{420}=\frac{85}{100}$ (The $\frac{85}{100}$ is 85% of the 100% people because 15% is missing)

When you cross-simplify you get: $\frac{x}{21}=\frac{85}{5}$ which is $\frac{x}{21}=17$

Finally, multiply 17 by 21 to get x.

Therefore, x=357

A certain building has a triangular shaped face to link up of the sides of the triangular base or 145 feet 257 feet in 290 feet

attashe74 [19]

Answer:

18617.66 ft^2

Step-by-step explanation:

sides of triangular base

a= 145ft ,

b = 257ft ,

c = 290ft

<u>calculate the area of the base </u>

The base is a scalene triangle hence the area is calculated as follows

s = ( a + b + c ) / 2

= ( 145 + 257 + 290 ) / 2 = 346

Area of triangle = $\sqrt{s(s-a)(s-b)(s-c)} = \sqrt{346(201)(89)(56)}$

= 18617.66 ft^2
