On the first day of June, there were about 17.71 h of daylight in a city. Five months later, there were about 5.30 h of daylig

Andru [333]

Answer:

Percentage increases and decreases, are found by setting the problem up proportionally.

You are trying to find what percentage of 17.37 is 8.30 first.

so What %/100 = 8.30/17.37

Now define a variable:

Let x = What%

x/100 = 8.30/17.37

17.37x = 830

x = 830/17.37

x ≈ 47.78

8.30 is approximately 47.78% of 17.37, so the percentage decrease is 100% - 47.78% = 52.22%

The percentage decrease is approximately 52.22%

Find the distance between the pair of points A(-1,8) and B(-8,4)

MAXImum [283]

Answer:

$\sqrt{65}$

Step-by-step explanation:

Solve using the distance formula:

$d = \sqrt{(x2 - x1)^2+(y2 - y1)^2}$

Input the corresponding numbers into the formula

$d = \sqrt{(-8 - (-1))^2+(4-8)^2}$

Solve

$d = \sqrt{49+16}\\ d =\sqrt{65}$

If 1/2 is subtracted from four times the reciprocal of a number, the result is 0. Find the number.

Maurinko [17]

Answer:

The Number is 8.

Step-by-step explanation:

Let the number be x.

Given:

1/2 is subtracted from four times the reciprocal of a number, the result is 0.

Hence the equation will become like;

$4\times \frac{1}{x} - \frac{1}{2}=0$

Now Solving the equation we get.

$\frac{4}{x} -\frac{1}{2}=0\\\\\frac{4}{x} = \frac{1}{2}\\\\x= 4\times 2\\x=8$

Now the we can see the number is 8, when 1/2 is subtracted from 4 times the reciprocal of number means 4/8 which becomes 1/2 and hence when 1/2 is subtracted from 1/2 it equals to 0.

Hence the number is 8.
