Answer:
70cm
Step-by-step explanation:
,
Since, both of the tank posses the same quantity of water then there volume is the same thing
For rectangular base
Volume= (Lenght × breadth × hheight)
If we substitute values
Lenght= 80 cm
Breadth= 70 cm
height= 45 cm
Volume= 80cm × 70cm × 45cm
Volume= 252000cm^3
For square base
Volume= (side)^2 × height
side =60cm.
But volume of square base= volume of
rectangular base
252000cm^3= 60^2 × height
Height= (252000cm^3)/(60^2 )
Height= 70 cm
Hence, the second tank is 70 cm deep
The solutions for ‘x’ are 2 and -5
<u>Step-by-step explanation:</u>
Given equation:
Since the base on both sides as ‘12’ are the same, we can write it as
Often, the value of x is easiest to solve by by factoring a square factor, setting each factor to zero, and then isolating each factor. Whereas sometimes the equation is too awkward or doesn't matter at all, or you just don't feel like factoring.
<u>The Quadratic Formula:</u> For , the values of x which are the solutions of the equation are given by:
Where, a = 1, b = 3 and c = -10
So, the solutions for ‘x’ are
The solutions for ‘x’ are 2 and -5
They can be expressed as fractions
they have positive values and can be expressed as terminating decimals.
