Answer: Choice A</h3>
The area of square T is equal to the sum of the areas of square R and square S.
=======================================================
Explanation:
Recall that the pythagorean theorem says
a^2+b^2 = c^2
Visually this means if we had a square with side length 'a', then its area is a^2. The same goes for a square with side length b. Its area is b^2
So a^2+b^2 is the sum of those square areas. It being equal to c^2 tells us that adding the smaller square areas lead to the largest square area.
So that's why the areas of squares R and S add up to the area of square T.
--------------
An example:
Let's say...
- square R has side length 3
- square S has side length 4
- square T has side length 5
note how 3^2+4^2 = 9+16 = 25 and how 5^2 = 25. This shows 3^2+4^2 = 5^2
Answer:
128
Step-by-step explanation:
896
7 goes into 8 once
Subtract 7 from 8 and bring the one down.
8 goes into 19 twice
Subtract 14 from 19 and bring the five down.
7 goes into 56 eight times.
So your answer is 128.
Hope this helps
Answer:
The number of teacher who joined the school is 20
Step-by-step explanation:
Teacher : Students = 1 : 16
Number of teachers = 1x
Number of students = 16x
16x = 1600
x = 1600/16
x = 100
Number of teachers at the beginning = 100
Now, after some teachers (let it be y) joining the school,
Teacher : students = 3:40

The number of teacher who joined the school is 20
