Arrange the following and ascending and descending order first one is 1 by 12 1 by 23 1 by 5 1 by 7 1 by 50 1 by 9 1/17

Nonamiya [84]

Answer:

Ascending order is given by

1/50<1/23<1/17<1/12<1/9<1/7<1/5

Descending order is given by

1/5>1/7>1/9>1/12>1/17>1/23>1/50

Step-by-step explanation:

We are given that

1/12,1/23,1/5,1/7,1/50,1/9,1/17

We have to arrange the numbers in ascending and descending order.

LCM of 12,23,5,7,50,9,17

$23\times 5\times 12\times 7\times 50\times 17\times 9$

=73899000

$\frac{1}{12}\times \frac{6158250}{6158250}=\frac{6158250}{73899000}$

$\frac{1}{23}\times \frac{3213000}{3213000}=\frac{3213000}{73899000}$

$\frac{1}{5}\times \frac{14779800}{14779800}=\frac{14779800}{73899000}$

$\frac{1}{7}\times \frac{10557000}{10557000}=\frac{10557000}{73899000}$

$\frac{1}{50}\times \frac{1477980}{1477980}=\frac{1477980}{73899000}$

$\frac{1}{9}\times \frac{8211000}{8211000}=\frac{8211000}{73899000}$

$\frac{1}{17}\times \frac{4347000}{4347000}=\frac{4347000}{73899000}$

14779800>10557000>8211000>6158250>4347000>3213000>1477980

Therefore,

Ascending order is given by

1/50<1/23<1/17<1/12<1/9<1/7<1/5

Descending order is given by

1/5>1/7>1/9>1/12>1/17>1/23>1/50

A rectangle with a length of L and a width of W has a diagonal of 10 inches. Express the perimeter P of the rectangle as a funct

KatRina [158]

<h2>Answer:</h2>

The expression which represents the perimeter P of the rectangle as a function of L is:

$Perimeter=2(L+\sqrt{100-L^2})$

<h2>Step-by-step explanation:</h2>

The length and width of a rectangle are denoted by L and W respectively.

Also the diagonal of a rectangle is: 10 inches.

We know that the diagonal of a rectangle in terms of L and W are given by:

$10=\sqrt{L^2+W^2}$

( Since, the diagonal of a rectangle act as a hypotenuse of the right angled triangle and we use the Pythagorean Theorem )

Hence, we have:

$10^2=L^2+W^2\\\\i.e.\\\\W^2=100-L^2\\\\W=\pm \sqrt{100-L^2}$

But we know that width can't be negative. It has to be greater than 0.

Hence, we have:

$W=\sqrt{100-L^2}$

Now, we know that the Perimeter of a rectangle is given by:

$Perimeter=2(L+W)$

Here we have:

$Perimeter=2(L+\sqrt{100-L^2})$

What is the answer too X2-3X+5=0

ivolga24 [154]

What is the solution (not answer) to (not too) x^2 - 3x + 5 = 0?
This is a quadratic equation. Two possible approches to solving it are
1) quadratic formula, and
2) completing the square.

Let's use the quadratic formula:

a=1, b= -3, c = 5

Then
-(-3) plus or minus sqrt( [-3]^2 - 4(1)(5) )
x = --------------------------------------------------------
2
3 plus or minus sqrt(9-20) 3 plus or minus i*sqrt(11)
= ------------------------------------- = ------------------------------------
2

Please note: These are complex roots, due to the " i ".

Delicious77 [7]

Answer:

B. 2.75 mph

Step-by-step explanation:

If it took him 2 hours to walk 5.5 miles, 5.5 ÷ 2 = 2.75, which is what he walked in a single hour, meaning he was walking 2.75 mph
