Answer:
30%
Step-by-step explanation:
We know if we put the number of records in the end ÷ the number of records previously, we can get the percentage change.
13/10 = 1.3
1.3 - 1 (Because we want to find the increase, not the amount of percentage this is to that)
0.3 = 3/10 = 30%

Answer:
Step-by-step explanation:
1/9 < 1/√n < 1/7
9 > √n > 7

n = 50, 51, 52, ..., 80
n has 31 possible values
Answer:
=
Step-by-step explanation:
AS we can see in the figure that a beam or a rod is balanced by a square on right side
while on the left side we have a smaller square and a triangle
Suppose the values written inside it are the weights of the shapes which are making it stable
So
Total on RHS = Total on LHS
Now Total on RHS = Value of bigger square
=
Total on LHS = Value of smaller sqaure + Value of triangle
=
Now we know to make this image a balanced one as shown n the figure
Total on RHS = Total on LHS
putting values gives us
=
which is the required equation
