A number increased by 4 is the same as 19-2 times the number

Please help me find the value of x

Mandarinka [93]

Answer:

$10 \sqrt{3}$

Step-by-step explanation:

<h2>Given Question, </h2>

To find the value of x.

<h2>Solution:</h2>

According to Pythagoras Theorem-

${20}^{2} = {10}^{2} + {x}^{2}$

$= > 100 + {x}^{2} = 400$

$= > {x}^{2} = 400 - 100$

$= > {x}^{2} = 300$

$= > x = \sqrt{300}$

$= > x = 10 \sqrt{3}$

<h2>Result:</h2>

Hence, the required value of x is 

 $10\sqrt{3}$

Type a digit that makes this statement true.

Aneli [31]

Answer:

1, 3, 5, 7, or 9

Step-by-step explanation:

For 14, 213, 1__2 to be divisible by 4, the last two digits must be divisible by 4.

Using this knowledge, any odd single digit number would make the statement true.

14, 213, 112 ÷ 4 = 3, 553, 278

14, 213, 132 ÷ 4 = 3, 553, 283

14, 213, 152 ÷ 4 = 3, 553, 288

14, 213, 172 ÷ 4 = 3, 553, 293

14, 213, 192 ÷ 4 = 3, 553, 298

Hope this helped!

A scientist has discovered an organism that replicates at a rate of five per hour and lives for one week. Each replicated organi

Assoli18 [71]

At hour one, there is 1 organism. At hour two, there is five more organism. At hour three. there will be 6 x 5 = 30 more organisms, etc

This is a geometric sequence with a = 1 (i.e. number of organisms at hour one), r = 5 (number of reprications per hour).

The total number of organisms at hour seven is the sum of the first seven terms of the sequence given by a(r^n - 1)/(r - 1) = 1(5^7 - 1)/(5 - 1) = (78125 - 1)/4 = 78124/4 = 19,531

Can y’all help me with this please will give you the brainliest

polet [3.4K]

Answer and Step-by-step explanation:

A pair of segments that are perpendicular to each other are the line segments:

KI (the letter i) and MJ.

This is because we see that at the intersection T, there a right angle symbol, which means that those 4 angles at the intersection are 90 degrees. When a line meets another line, and it is perpendicular to that line, they form 90 degrees.

So, those line segments are perpendicular.
