Answer:

W = 20 (woman's age)

M = 60 (man's age)

Step-by-step explanation:

M = Man's age

W = Woman's age

M + 20 = 2(W + 20)

Sub for M

3W + 20 = 2W + 40

W = 20 (woman's age now)

M = 60 (man's age now)

(-2, 11) &amp; (5,6)<br> What is the slope of the equation between these two points?
ololo11 [35]

Answer:

m =\dfrac{-5}{7}

Step-by-step explanation:

<u>Given </u><u>:</u><u>-</u><u> </u>

  • Two points (-2,11) and (5,6) .

And we need to find out the slope of the equation between the two points. The slope of the line passing through two points , is given by ,

\implies Slope (m) =\dfrac{ y_2-y_1}{x_2-x_1}

  • Here the two points are (-2,11) and (5,6) .So put on the respective values ,

\implies Slope (m) =\dfrac{ 11 - 6}{-2-5}\\\\\implies Slope = \dfrac{5}{-7} \\\\\implies Slope = \dfrac{-5}{7}

<u>Hence</u><u> the</u><u> </u><u>slope</u><u> of</u><u> the</u><u> line</u><u> is</u><u> </u><u>-</u><u>5</u><u>/</u><u>7</u><u> </u><u>.</u>

On a map the perimeter of the is 0.251 meters. The actual perimeters of the park is 1,000 times as large. What is the actual per
raketka [301]

The actual perimeter of the park is \boxed{\bf251{\text{ meters}}}.

Further explanation:

Given:

The perimeter of the park is on a map 0.251{\text{ meters}}. The measured perimeter of the park is 1000 times as large.  

Calculation:

The distance of the closed figure is called as the perimeter.

The perimeter of the attached Figure 1 can be calculated as,

\begin{aligned}{\text{Perimeter}}&=a+a+b+b\\&=2\left({a+b}\right)\\\end{aligned}

Here, x,y{\text{ and }}z is the length of the shape.

From place value chart, 10 tens is equal to 1 hundreds.

Tenths are one place after the decimal and hundredths are two places after the decimal.

Two tenths can be written in the form of decimal as follows:

\dfrac{2}{{10}}=0.2

Five hundredths can be written in the form of decimal as follows:

\dfrac{5}{{100}}=0.05

One thousandths can be written in the form of decimal as follows:

\dfrac{1}{{1000}}=0.001

Therefore, the number 0.251 can be written as,

\begin{aligned}0.251&=\frac{2}{{10}}+\frac{5}{{100}}+\frac{1}{{1000}}\\&=0.2+0.05+0.001\\&=0.251\\\end{aligned}

On the map the perimeter of the park is 0.251{\text{ meters}}.

Let {\text{P}} be the actual perimeter of the park.

The actual perimeter of the park can be calculated as follows,

\begin{aligned}{\text{P}}&=0.251\times1000\\&=251{\text{ meters}}\\\end{aligned}

Thus, the actual perimeter of the park is \boxed{\bf251{\text{ meters}}}.

Show that the sum of the first 2n natural numbers is n(2n+1)
Leokris [45]

Answer:

This sum is the sum of an arithmetic sequence.  There is a formula for the sum of an arithmetic sequence which can be looked up or derived by a variety of means.

A nice approach for this sequence is the following.  Notice  that the sum of first and last number in the sequence is the same as the sum of the second and second last, and also the same as the sum of the third and third last, and so on.

There are n of these pairs.  So the desired sum is n x (first number + last number).   But the first number is 1 and the last on is 2n.   Thus the desired sum is n(1 + 2n).

Hope this helps!!
