The meals for all 9 cost 9x5 = $45
225-45= $180 which represent the entrance fees for all 9.
We divide that to 9 and we get the entrance fee per student!
180/9 = $20 / fee per student!
Both 24 and 25 are rational. They can be turned into a fraction by putting a 1 as the denominator.
Correct option is C. The Amazon River carries more water than any other river in the world.
The Amazon River carries more water than any other river in the world. In fact, the Amazon River is responsible for about one-fifth (twenty percent) of the fresh water that flows into the world's oceans. The Amazon River is the second longest river in the world and is about 4,000 miles (6400 km) long.
The Amazon is considered the world's largest river by volume, but scientists have believed it is slightly shorter than Africa's Nile. The Brazilian scientists' 14-day expedition extended the Amazon's length by about 176 miles (284 kilometers), making it 65 miles (105 kilometers) longer than the Nile.

Answer:
40 ft
Step-by-step explanation:
The fiagram shows the right triangle (one angle is right angle).
By the Pythagorean theorem,
From the diagram,
then
Try this option:
According to property such triangle
1. area=0.5*a*b, where a and b - the sides of angle 90°.
Using this equation: 180=0.5*40*b, ⇒ b=9.
2. c²=a²+b², ⇒c=√(9²+40²)=41 - the third side of the triangle;
3. Perimeter=a+b+c=9+40+41=90 cm.
answer: 90 cm.
