7 men build a house in 300 days. How many men will it take if they work at the same tempo, buil the house in 70 days?

Chan receives a bonus from his job. He pays 30% in taxes, gives 30% to charity, and uses another 15% to pay off an old debt. He

Answer:

Chan's Bonus amount was $2400.

Step-by-step explanation:

Let the Total amount receive from bonus be 'x'.

Given:

Chan pays 30% in taxes;

So we can say;

Amount paid in taxes will be equal to 30% of total amount receive

framing in equation form we get;

Amount paid in taxes = $\frac{30}{100}x=0.3x = 0.3x$

Now Given:

Chan pays 30% in Charity;

So we can say;

Amount paid in charity will be equal to 30% of total amount receive.

framing in equation form we get;

Amount paid in Charity = $\frac{30}{100}x=0.3x$

Also Given:

Chan pays 30% in old debts;

So we can say;

Amount paid in Old debts will be equal 30% of total amount receive

framing in equation form we get;

Amount paid in Old debts = $\frac{15}{100}x=0.15x$

Money left with him = $600

Now we can say that Total Amount Receive in bonus will be equal to Amount paid in taxes plus Amount paid in charity plus Amount paid in old debts plus amount left.

framing in equation form we get;

$x=0.3x+0.3x+0.15x+600\\\\x= 0.75x +600\\\\x-0.75x=600\\\\0.25x=600\\\\x=\frac{600}{0.25} = \$2400$

Hence Chan's Bonus amount was $2400.

How do you evaluate logarithms? Explain using an example or mathematical evidence to support your answer.

kenny6666 [7]

Answer: Explanation below.

Step-by-step explanation:

First of all you need to know how to convert a logarithm into an exponential expression. The property is:

$log_Bx=n$

This is the same as: $B^n=x$

Example 1:

$log_99=$

We are trying to find what to raise 9 to, in order to get a result of 9.

$9^x=9$

When you have same bases, you equal exponents.

$x=1$

Therefore; $log_99=1$

Example 2:

$log_232=$

$2^x=32$

In this case, we have to make sure both sides have the same base. 32 can have a base of 2 if expressed as: $2^5$ which is 2*2*2*2*2

Rewriting this example we have;

$2^x=2^5$

Since we have the same base, we equal exponents.

$x=5$

Therefore; $log_232=5$

Example 3:

$log_3729=$

$3^x=729$

729 can have a base of 3 if expressed as: $3^6$

$3^x=3^6$

$x=6$

Answer:

Therefore, we conclude that the probability is P=0.3456.

Step-by-step explanation:

We know that there is a 0.60 probability that a random student at UMSL has watched Game of Gnomes. We calaculate the probability that 3 of 4 students watched Game of Gnomes.

$p=0.6\\q=1-0.6=0.4\\$
