Answer:

\frac{3x^3z^5}{5y} ( \frac{20y^3}{x^2z^6})

Step-by-step explanation:

When given the following equation,

\frac{3x^3z^5}{5y} ÷ \frac{x^2z^6}{20y^3}

The first step is to convert the equation into a form that can be solved, in essence dividing any number by a fraction is the same as multiplying that number by the reciprocal of the fraction. The reciprocal of a fraction is when one switches the position of the numerator and denominator, the numerator is the number on top of the fraction, and the denominator is the number underneath the fraction.

\frac{3x^3z^5}{5y} ÷ \frac{x^2z^6}{20y^3}

\frac{3x^3z^5}{5y} * \frac{20y^3}{x^2z^6}

Simplify, reduce the numbers that are found in common between the numerator and denominator,

\frac{3x^3z^5}{5y} * \frac{20y^3}{x^2z^6}

\frac{3x^3z^5*20y^3}{5y*x^2z^6}\\\\=\frac{3x*4y^2}{z}\\\\=\frac{12y^2x}{z}

Answer:

Time taken by the un powered raft to cover this distance is T = 192.12 hr

Step-by-step explanation:

Let speed of boat = u

Speed of current = v

Let distance between A & B = 100 km

Time taken in downstream = 32 hours

u + v = 3.125 ------ (1)

Time taken in upstream = 48 hours

u - v = 2.084 ------- (2)

By solving equation (1) & (2)

u = 2.6045

v = 0.5205

Now the time taken by the un powered raft to cover this distance

Because un powered raft travel with the speed of the current.

T = 192.12 hr

Therefore the  time taken by the un powered raft to cover this distance is

T = 192.12 hr

Help me please this is very important
uranmaximum [27]
I think it would just be 13 because T to U is 11 and U to V is 2 so if you want to find T to V you would add them together

Hope this helps in any way :))
