Answer:

\frac{1}{32} of work is done on friday

Step-by-step explanation:

Let x denotes the amount

On Monday :

Work done = \frac{x}{2}

Work left : x-\frac{x}{2}=\frac{x}{2}

On Tuesday :

Work Done = \left ( \frac{1}{2} \right )\frac{x}{2}=\frac{x}{4}

Work Left = \frac{x}{2}-\frac{x}{4}=\frac{x}{4}

On Wednesday :

Work Done = \frac{1}{2}\left ( \frac{x}{4} \right )=\frac{x}{8}

Work Left = \frac{x}{4}-\frac{x}{8}=\frac{x}{8}

On Thursday :

Work Done = \left (\frac{1}{2}  \right )\frac{x}{8}=\frac{x}{16}

Work Left = \frac{x}{8}-\frac{x}{16}=\frac{x}{16}

On Friday :

Work Done = \frac{1}{2}\left ( \frac{x}{16} \right )=\frac{x}{32}

If Adam and Eve were white then how are black people made, from brown cows? Not trying to be racist UwU
Free_Kalibri [48]

Answer:

If you want me to be honest with you, I will be. The reason black people got their skin color is really because someone was born with a lot of melanin, and what caused that was basically the region and climate the people are living in. People in Africa are most likely to be darker than those who live in Northern Europe.

Express each expression as a single logarithm.​
andreev551 [17]

Answer:

1. 6

2. 23

Step-by-step explanation:

1.

logx+1 ( x^2 + 2x + 1)^3

= 3logx+1  ( x^2 + 2x + 1)

= 3 logx+1 (x + 1)^2

= 6 logx+1 (x + 1)  Now the logx+1 x+1 = 1  so

The answer is 6.

2.

log11 11^23

= 23 log11  11

As in question 1 log11 11 = 1

So the answer is 23.
