The length and breadth of a rectangular playground are 110m and 90m.
(a) Ratio of length to perimeter = 11 : 40
(b) Ratio of breath to perimeter = 9 : 40
<u>Solution:
</u>
Given that length of play ground = 110 m
And breadth of playground = 90 m
Need to determine ration of (a) length to perimeter and (b) perimeter to breadth
Lets first calculate perimeter of rectangular playground
<em>Perimeter of Rectangle = 2(length + breadth ) </em>
=> Perimeter of Rectangular playground = 2(110 + 90) = 400 square meter
Now substituting values in ratio we get,
(a) Ratio of length to perimeter = 110 : 400 = 11 : 40
(b) Ratio of breath to perimeter = 90 : 400 = 9 : 40
The graph of a linear function is a line

A)f(x) = -2 line
</span>
B)f(x) = x - 2 line<span>
C)f(x) = 2x </span>line<span>
D)f(x) = x</span>² parabola
So, D)f(x) = x² <span>is not a linear function</span>
Answer:
Step-by-step Explanation:
Angle of depression is congruent to angle of elevation.
Therefore, angle of elevation of the given figure, which is opposite to x is 25°.
Adjacent length = 11 yd
Opposite length = x
Trigonometric ratio formula for finding x is shown below:
Multiply both sides by 11 to solve for x

The price of citizen tickets is $15 and the price of child tickets is $12
To equations are equivalent if and only if they have the same solution set.
Solve for both of the equations.
-2x = 10
x = -5 <-- Divide both sides by -2
-5x = 25
x = -5 <-- Divide both sides by -5
Both have the solution -5.
So, yes both are equivalent.
