3 biscuits cost 24p
Answer:
-29/20
Step-by-step explanation:
The cosecant function is the inverse of the sine function. Both sine and cosecant are odd functions, meaning csc(-x) = -csc(x) = -1/sin(x).
csc(-θ) = -1/sin(θ) = -1/(20/29) = -29/20
Perimeter of a closed figure is the sum of length of its outline. The perimeter of the consider triangular pool is:
units.
<h3>How to calculate perimeter of a triangular figure?</h3>
Perimeter of a triangle = Sum of lengths of all its 3 sides.
For the given case, we have:
Length of first side(hypotenuse) =
units
Height =
units
Base is of length 
Thus, its perimeter is calculated as:
Perimeter of a triangle = Sum of lengths of all its 3 sides.
Perimeter =
units
Perimeter =
units
Thus,
The perimeter of the consider triangular pool is:
units.

because 3 gallons are lost per minute so 3 x 10.5= 31.5
24. (2x+2)+(2x+2)+(2x+2)=(x+8)+(x+8)+(x+8)+(x+8)
6x+6=4x+32
-6 -6
6x=4x+26
-4x -4x
2x/2=26/2
