Answer:
They cost 730 all together.
Step-by-step explanation:
One the surface area of the hall is 310m^2.
so, 310 divided by 25 is 12.4, which means they need 13 tin of paint.
The cost for it is 13*10 which is 130.
For the area of the floor, it is 40*15, which is 600m^2.
Which costs 600.
So, 600+130=730.
The Sine or Sinθ in a right-angle triangle is the ratio of its perpendicular to its Hypotenuse. The distance between the kite and the ground is 57.547 feet.
<h3>What is Sine (Sinθ)?</h3>
The Sine or Sinθ in a right-angle triangle is the ratio of its perpendicular to its Hypotenuse. It is given as,
Sin(θ) = Perpendicular/Hypotenuse
where,
θ is the angle,
Perpendicular is the side of the triangle opposite to the angle θ,
The hypotenuse is the longest side of the triangle.
For the given situation, the diagram can be drawn as shown below. Therefore, the distance between the ground and the kite is AB,
Sin(46°) = AB/AC
AB = Sin(46°) × 80 feet
AB = 57.547 feets
Hence, the distance between the kite and the ground is 57.547 feet.

Answer:
Prime
Step-by-step explanation:
The roots are irrational. (If they were rational, they would be factors of 8.) As a consequence, the expression has no factoring in integers, making it prime.
