M = 4
Because the base of log is 10
10,000 is 10*4, and we know that log 10,000 =4, so M=4

Tap A can fill 4 pails in 55 seconds.
rewona [7]

Answer:

Below in bold.

Step-by-step explanation:

Work in times to fill 1 pail:-

tap A takes 55/4 seconds

tap B takes 50/3 seconds

Let time to fill one pail be x when filling together, then:

3/50 + 4/55 = 1/x

165x + 200x = 55*50

x = 2750 /(365) = 7.5342 seconds

To fill 16 pails it takes 7.5342* 16

= 120.55 seconds

= 2 minutes 1 second to the nearest second..

Help me answer the question j
Marianna [84]

The value of the expression is 252

Step-by-step explanation:

The expression that we have to evaluate in this problem is

7x^2y

And we have toe valuate it for

x = 3

y = 4

In order to evaluate the expression, let's substitute the values of x and y into it:

7x^2y=7\cdot (3)^2\cdot (4)

First, we calculate the square of 3, which is:

3^2 = 3\cdot 3 = 9

Substituting into the expression,

7\cdot 3^2 \cdot 4 = 7\cdot 9 \cdot 4

Now we multiply everything and we get:

7\cdot 9 \cdot 4 = 252
