Use the Pythagorean theorem to find the length of side FD.

Answers

Answer: i think its 9 but sorry if I'm wrong I'm only in 4th grade

Step-by-step explanation:

It’s 10

In triangle ABC:
3^2+4^2= c^2
9+16=25
Square root of 25 is 5, so hypotenuse of triangle ABC is 5.

For triangle DEF, not that the given side is 8, which twice the amount of four. To find the other adjacent side of the triangle, we will multiply 3 by 2 because that is what we did with the 4. by doing this we can conclude that our other side is of the triangle is 6 Then, we have this pythagorean theorem to solve for FD:

8^2+6^2= C^2

64+36=100

C^2=100

The square root of the 100 is 10, therefore the length of side FD is 10.






A triangle has perimeter 3a+11. One side is 2a and another side is 8. What is the third side?

Answers

Answer:

1a + 3

Step-by-step explanation:

What's the perimeter of a triangle?

  ❖ The perimeter of a triangle is the distance around a triangle, or the

       sum of all its side lengths.

How does it apply here?

  ❖ In this case, we're given the perimeter of the triangle as 3a + 11. We

      also have two dimensions of the triangle: 2a and 8. Now, we need to

      find the third side. To find the third side, we subtract 2a + 8 from 3a +

      11.

Solving

[tex](3a+11)-(2a+8)[/tex] [tex]3a+11-2a-8[/tex] [tex]1a+3[/tex]

Now, let's check if 1a + 3, 2a, and 8 add up to 3a + 11.

[tex]1a + 3 + 2a + 8[/tex] [tex](1a+2a)+(3+8)[/tex] [tex]3a+11[/tex]

Therefore, the answer is 1a + 3.

Answer:

.5, 3, 8.5

Step-by-step explanation:

Divide the minutes by 2 since 6 is half of 12.Half of 1 is .5 or [tex]\frac{1}{2}[/tex]Half of 6 is 3Half of 17 is 8.5

If I am incorrect in my reasoning, please let me know so that I can plan better for my future answers. Have an amazing day.

Step-by-step explanation:

Pages is directly proportional to Minutes

P = KM

k = P/M

when P = 6, M = 12.

k = 6/12

k = 0.5

_____________________

when M = 1

P = Km

P = 0.5×1 = 0.5

P = half a page.

______________________

when M = 6

P = 0.5× 6

P = 3 pages

______________________

when M = 17

P = 0.5×17 = 8.5

P = 8 and half pages

PLEASE HELP FAST!!! Denise measured a community college and made a scale drawing. In real life, a building at the college is 122 meters long. It is 183 centimeters long in the drawing. What scale did Denise use?
3 centimeters : how many meters

Answers

183/3=61
122/61= 2
ratio is 3cm:2m

The scale that Denise used for a community college and made a scale drawing is 3 centimetres: 2 meters.

Given that;

Denise measured a community college and made a scale drawing.

Now, for the scale Denise used, set up a proportion using the measurements from the drawing and real life.

So, from the proportion:

3 centimetres (drawing): x meters (real life) = 183 centimetres (drawing): 122 meters (real life)

Using cross-multiplication, solve for x:

3 centimeters × 122 meters = 183 centimeters × x meters

366 centimeters meters = 183 centimeters x meters

Now divide both sides of the equation by 183 centimetres to isolate x:

366 centimetres meters / 183 centimetres = x meters

x = 2 meters

Therefore, the scale Denise used is 3 centimetres: 2 meters.

Hii.

First, lets divide 1/9 by 5 .

1/9 divided by 5 is 1/45

Lets multiply to find out the answer.

1/9 x 5 =5/9.

So this is not correct since it does not equal 1/45

9/1 x 5/1 is 45

This is not correct because it does not equal 1/45

1/9 x 1/5 is 1/45

This is correct because it equals 1/45

Algebra Mathematics
Question 1
Mr Brown has several models of famous people that each weigh the same. He decides to add in some new models that are of different weights to his old ones. In Room Number One, there are five old models along with a new model that weighs 240kg.
In Room Number Two, there are 3 old models along with a new model that weighs 510kg.

THE TOTAL WEIGHT OF THE MODELS IN ROOM ONE IS EXACTLY THE SAME AS THE TOTAL WEIGHT OF THE MODELS IN ROOM TWO.
What is the weight of an old model?

Answers

Answer:

135kg

Step-by-step explanation:

In room number one, there are five old models and a new model, which weights 240kg. So, it can be concluded that there are 6 models in there, and we can write it as 5x ( x = old models ) + 240 ( weight of new model ). then informed room number two, there are 3 old models and a new one, weighting 510kg. write it as 3x + 510.

the equation will be as: 5x + 240 = 3x + 510

move 3x to the front behind 5x, move +240 to the back behind 510. you will get 5x - 3x = 510 -240

which will be 2x = 270, then move 2 behind 270, means 270 divide 2, which then you will get 135kg

In room number one, there are five old models and a new model, which weights 240kg.
