Mila [183]3 years ago
6 0

Answer:

\large\boxed{\pm\dfrac{5}{2}=\pm2.5}

Step-by-step explanation:

\sqrt{a}=b\iff b^2=a\\\\\pm\sqrt\dfrac{25}{4}}\qquad\text{use}\ \sqrt{\dfrac{a}{b}}=\dfrac{\sqrt{a}}{\sqrt{b}}\\\\=\pm\dfrac{\sqrt{25}}{\sqrt{4}}=\pm\dfrac{5}{2}=\pm2.5\\\\\text{because}\\\\\left(\dfrac{5}{2}\right)^2=\dfrac{25}{4}\ \text{and}\ \left(-\dfrac{5}{2}\right)^2=\dfrac{25}{4}

What is the degree of vertex B and G?
Marat540 [252]

Answer:

degree of vertex B = 2

degree of vertex g = 4

Step-by-step explanation:

Using given picture we need to find about what is the degree of vertex B and G.

In graph theory, we know that the degree (or valency) of a vertex of a graph is the number of edges incident to the vertex.

So we just need to count how many edges are incindent on vertex B and G.

From picture we see that number of edges incident on vertex B = 2

Hence degree of vertex B = 2

From picture we see that number of edges incident on vertex G = 4

Hence degree of vertex g = 4

Four plumbers estimated the length of the radius of a cylindrical pipe. the estimates made by the plumbers are listed. • plumb
myrzilka [38]

The correct order of the radius  \sqrt{3} /11 \ , \pi /24 ,  3/25  ,  9/100 .

What is decreasing and increasing order?

A set of data is said to be in descending order, often referred to as decreasing order, when it is arranged from highest to lowest or largest to smallest.

The same concepts apply regardless of the type of information you're working with, whether it's letters, dates, sizes of things or any other group of information like numbers or dates.

For instance, arranging a group of numbers in descending order means doing so from biggest to smallest value.

Ascending order, often known as ascending order of importance, is the exact opposite of declining order.

The order of the items is lowest to highest value. The lowest value is placed first in the order, while the highest value is placed last.

The value of \sqrt{3} = 1.732

so \sqrt{3} / 11 = 1.732/11

=1732/11000

The value of pi = 3.14

so \pi / 24  = 3.14/24

= 314/2400

Use the given equation to find the number<br><br> 1/2x-19.7=-4.1
Leokris [45]

Answer:

the number is 31.2

Step-by-step explanation:

Given that:

1/2x-19.7=-4.1

Adding 19.7 on both sides:

1/2x-19.7 + 19.7=-4.1 + 19.7

1/2x = 15.6

Multiplying both sides by 2:

x = 15.6 * 2

x = 31.2

So the number is 31.2

i hope it will help you!
