Answer:
25/12 square feet
Step-by-step explanation:
The area of a rectangle can be found using the formula A=l*w. Here l = 5/4 and w=5/3. Substitute the values into the formulas.
A=l*w
A=(5/4)(5/3)
A=25/12 square feet
3. Is 4 2. Is x hoped this helped
Okay so here's how i think you solve it
both triangles have the same ratio, so set it as 3/4.5 (the smaller triangle) is equal to X/13.5 (the 9 added to the 4.5)
multiply 13.5/1 on both sides to get x alone
13.5 3
-------- x ------- = x x= 9
1 4.5
we know that
The radius of the hydrogen atom is 
The radius of the nucleus is
m
the ratio is equal to

that means the radius of the hydrogen atom is 44,083.33 times the radius of the nucleus
therefore
<u>the answer is</u>
the ratio is equal to 44,083.33
