Answer:
420
Step-by-step explanation:
The number of students in the school is unknown, so we'll call it x.
55% of the number of students are girls.
There are 321 girls.
55% of x = 231
0.55x = 231
x = 231/0.55
x = 420
Answer: 420
So you know 1 gallon equals 16 cups
So you multiply 16 times 3 equals 48

Answer:
<h3>The increase of amplitude would increase distance between the maximum and minimun point of the wave.</h3>
Step-by-step explanation:
We can defined the amplitude of a wave as the height of it, because it's the distance from the maxium point to the minimum point. In other words, it's the longest vertical displacement along the wave.
Additionally, amplitude represents power, when we apply waves to real phenomenons like the sound. So, greater grade of amplitude would represent louder sounds.
Therefore, the increase of amplitude would increase distance between the maximum and minimun point of the wave.
Answer:
Being a triangle is more like being a quadrilateral than it is like being a rectangle or a square. ... Children need to know that you can have lots of different side lengths and angles in a triangle, but if it's a square then all of the sides have to have the same length, and all of the angles have to be right angles.
