The two triangles are similar.
40/x = 32/4
x = 5
Answer:
x = 
Step-by-step explanation:
The segment from the vertex to the base is a perpendicular bisector.
Using Pythagoras' identity on the right triangle on the left.
x² = 2² + 3² = 4 + 9 = 13 ( take the square root of both sides )
x =

Answer:
Option B - 2
Step-by-step explanation:
We have given, the length of a spring when it’s at rest is measured to be 0.56 centimeter.
We have to find, how many significant figures are there in this measurement?
Solution :
The rules to get the significant figure are
- Non-zero digits are always significant.
- Any zeros between two significant digits are significant.
- A final zero or trailing zeros in the decimal portion ONLY are significant.
The given measurement is 0.56 cm.
It has two trailing zeros in the decimal i.e. 5 and 6.
There are only two significant figures.
Therefore, Option B is correct.
Answer:
A
Step-by-step explanation:
Let's assume the first pool to have dimensions 3.0 by 2.0
The second pool being 2.1 times the first will have dimensions 6.3 * 4.2
The area of the first pool is 6.0 and that of the second is 26.46
making the area of the second pool 4.41 times that of the first.
