The triangle below is isosceles. Find the length of side x in simplest radical form with
a rational denominator.
x
4

Answers

Answer:

4√2

Step-by-step explanation:

as it is an isosceles 2 sides will have the same side length so 4 and 4, therefore you can use pythagoras theorem to solve for x.

do 4²+4²=32 then square root this √32 which is equal to 4√2

The two sides in the isosceles triangle will be the same thus the value of the third unequal side x will be 4√2.

What is a triangle?

A triangle is a closed, 2-dimensional shape with 3 sides, 3 angles, and 3 vertices.

In a triangle, the sum of all three angles is 180°

Triangle is a very common figure to deal with our daily life for example in our daily life to measure the height of any tower then there is a huge application of the right angle triangle.

As per the given isosceles triangle.

The angles opposite to equal sides in the isosceles triangle will be the same.

And, The two sides of the isosceles triangle will be the same.

Both perpendicular sides' length = 4

By Pythagoras theorem,

x = √(4² + 4²)

x = √32 = 4√2

Hence "The two sides in the isosceles triangle will be the same thus the value of the third unequal side x will be 4√2".

Please show working.

Answers

[tex]3x-25 =11x -5 +2x \\\\\implies 3x -25 = 13x-5\\\\\implies 13x -3x = 5-25\\\\\implies 10x = -20\\\\\implies x = -2[/tex]

Answer: x=-2.

Step by step:

3x-25=11x-5+2x

Combine like terms!

3x-25=(11x+2x)+(-5)

3x-25=13x+(-5)

3x-25=13x-5

Subtract 13x on both sides!

-10x-25=-5.


Add 25 to both sides.

-10x=20.

Divide both sides by -10.

x=-2.

There are
r red marbles and g green marbles in a bag. When one red marble is removed and one green marble added, the ratio of red to green marbles is now 2:3 .

Subsequently, 6 red marbles and 4 green marbles are added, such that the ratio of red to green marbles is now 3:4.

What is the ratio of r to g? Your ratio must be in its simplest form.

Answers

The ratio of red marbles to green marbles, [tex]r:g=5:7[/tex]

The first sentence about what happens to the bag of marbles;

"When one red marble is removed and one green marble added, the ratio of red to green marbles is now 2:3"

Leads to the fractional equation

[tex]\frac{r-1}{g+1}=\frac{2}{3}[/tex]

After rearranging, we get equation (1) [tex]3r-2g=5[/tex]

The next sentence about what happens to the bag of marbles;

"Subsequently, 6 red marbles and 4 green marbles are added, such that the ratio of red to green marbles is now 3:4"

Leads to the fractional equation

[tex]\frac{r-1+6}{g+1+4}=\frac{3}{4}\implies \frac{r+5}{g+5}=\frac{3}{4}[/tex]

Since the first change to the bag was done without replacement. After rearranging, we get equation (2) [tex]4r-3g=-5[/tex]

So we need to solve the simultaneous equations for [tex]r[/tex] and [tex]g[/tex]

[tex]3r-2g=5\\4r-3g=-5[/tex]

Which gives [tex]r=25[/tex] and [tex]g=35[/tex]

Therefore, the ratio, [tex]r:g=25:35=5:7[/tex]

Step-by-step explanation:

a. 5n = 30

n=6

b. 3n-1 = 11

3n= 11 + 1

n = 12 ÷3

n=4

Find the value of h and k.

Answers

Answer:

  h = 6, k = 6.5

Step-by-step explanation:

The segment marked h is half the length of the one marked 3h-6.

  2h = 3h -6

  6 = h . . . . . . . add 6-2h

__

The segment marked k is half the length of the one marked 2h+1.

  2k = 2(6) +1

  k = 13/2 = 6.5 . . . . divide by 2

The values of h and k are 6 and 6.5, respectively.

Which is the correct equation to find the missing side?

Answers

Answer:

( AB )² + 12 = 162

Step-by-step explanation:

By Pythagoras theorem,

( AB )² + ( BC )² = ( AC )²

( AB )² + ( 2√3 )² = ( 9√2 )²

( AB )² + 12 = 162

Step-by-step explanation:

it's a right angled triangle so to find the measures of 3rd side we use hypotenuse formula which is,

h² = a² + b²

here in the given figure we have to find base or b²

(AC)² = (CB)² + (AB)²

we know,

AC = 9√2

CB = 2√3

now,

162 = 12 + AB

THEREFORE, OPTION B is correct.

However, not all people have those abilities. Some are born without the ability to speak, see, or hear. Others lose one or all of these abilities due to illness or accident. Not being able to communicate can be a major obstacle, but people who overcome these challenges are often determined, resourceful, and dedicated to helping others. Instead, people who have to overcome these challenges are often determined, resourceful, and dedicated to helping others.A Great TeacherOne person who did not allow her disability to limit her was Helen Keller. Keller, who became blind and deaf at the age of one and a half due to illness, learned at a very young age that her life was going to be different. As a child in the late 1800s, she did not have access to the technology we have today that assists people with disabilities in their daily lives. Instead, she had a very dedicated and creative teacher who stuck with Keller throughout her life. This teacher's name was Anne Sullivan. As a result of Sullivan's dedication and Keller's own determination, she learned when many thought she could not.Learning How to CommunicateSullivan helped her learn to communicate by using the resources and abilities Keller did have. Keller could touch, taste, and smell. Sullivan taught her to associate hand movements with words. She would spell words on Keller's hand while having her touch the related object. By associating a physical object with the hand movements, Helen learned the meaning of countless words. Learning to speak was tackled in a similar way. By feeling lips as they moved, Keller learned how to use her lips to form words. Using such innovative techniques and the resources available to her opened whole new worlds for Keller's learning. Sullivan encouraged and mentored Keller, never letting her give up and always believing the best for her.An Inspiration to OthersAnother way Keller learned to communicate was through writing. As an adult, she attended Radcliffe College, which allowed her to advance her education, even though many people doubted her ability to be successful. While she was there, she wrote her autobiography, which told the world about her struggles and accomplishments. She was able to share her story through Braille, a form of writing using raised dots felt with the fingers. Throughout her entire college career, Anne Sullivan was beside her, encouraging Keller and interpreting the words she could not see and the sounds she could not hear. Helen Keller's perseverance and Anne Sullivan's dedication became an inspiration for many children and adults around the world.Helen Keller went on to be a successful author and teacher. She became a mentor to other children and adults living with disabilities. To this day, Keller is remembered for her determination, resourcefulness, and dedication that helped her to overcome obstacles and inspire others.Which details best support the claim that Keller learned to communicate successfully?
