What is the value of x and the length of segment DE?
1. 5/9= 9/(2x+3)
2. 10x + 15 = 9(9)
x=?
length of de=?
Answer:
[tex]x = 6.6[/tex] and [tex]DE = 16.2[/tex]
Step-by-step explanation:
The question is incomplete as the attachment to solve segment DE is missing. However, see attached for complete question.
Given
[tex]\frac{5}{9}= \frac{9}{(2x+3)}[/tex]
Required
Find x
Length of DE
To find x, we need to first simplify the given equation
[tex]\frac{5}{9}= \frac{9}{(2x+3)}[/tex]
Multiply both sides by [tex]9(2x+3)[/tex]
[tex]\frac{5}{9} * 9(2x + 3) = \frac{9}{(2x+3)} * 9(2x + 3)[/tex]
[tex]5(2x + 3) = 9(9)[/tex]
[tex]10x + 15 = 81[/tex]
Subtract 15 from both sides
[tex]10x + 15 - 15 = 81 - 15[/tex]
[tex]10x = 66[/tex]
Divide both sides by 10
[tex]\frac{10x}{10} = \frac{66}{10}[/tex]
[tex]x = \frac{66}{10}[/tex]
[tex]x = 6.6[/tex]
From the attached;
[tex]DE = 2x + 3[/tex]
Substitute 6.6 for x
[tex]DE = 2(6.6) + 3[/tex]
[tex]DE = 13.2 + 3[/tex]
[tex]DE = 16.2[/tex]
Hence [tex]x = 6.6[/tex] and [tex]DE = 16.2[/tex]
Answer: 6.6 for the first x
Length of DE is 16.2
Also these are correct!

The number of laughs (denoted by L) can be defined as a function of the number of jokes (denoted by J), the amount of knowledge about the joke material (denoted by K), and the familiarity with the jokes (denoted by F) using this formula:
Answer:
L = f(J, K, F)
L = (JK²)/F
So, as the formula appears, the appropriate units will be option A.
Unit for number of laughs = (jokes*knowledge²) / familiarity
Just like the formula suggests.
Step-by-step explanation:
Complete Question
The number of laughs (denoted by L) can be defined as a function of the number of jokes (denoted by J), the amount of knowledge about the joke material (denoted by K) and the familiarity with the jokes (denoted by F) using this formula: L = (JK²)/F
Select an appropriate unit for number of laughs:
A) (jokes*knowledge²) / familiarity
B) familiarity / (jokes*knowledge²)
C) familiarity² / (jokes*knowledge)
D) (jokes*knowledge) / familiarity²
Solution
L = f(J, K, F)
where
L = number of laughs
J = number of jokes
K = amount of knowledge about the joke material
F = familiarity with the jokes
Analysing how the dependent variable depends on each of the independent variables.
- Number of jokes
The number of laughs will increase with the number of jokes and vice versa. It can be stated that there is a direct variation between the number of laughs and number of jokes.
- Amount of knowledge about the joke material
The more one understands the joke material, the funnier the joke. In fact, the joke can be termed funnier when one understands the joke material deeply. The direct variation of number of laughs to knowledge about joke material isn't just enough, the number of laughs varying directly as the square of the knowledge of joke material seems more fitting.
- Familiarity with the joke
The more familiar one is with a joke, the less funny it is. Hence, it's an inverse relationship between number of laughs and the familiarity with the joke.
L = (JK²)/F
So, as the formula appears, the appropriate units will be
(jokes*knowledge²) / familiarity
Just like the formula suggests.
Hope this Helps!!!
The question is incomplete. Here is the complete question.
The number of laughs (denoted by L) can be defined as a function of the number of jokes (denoted by J), the amount of knowledge about the joke material (denoted by K) and the familiarity with the jokes (denoted by F) using this formula: [tex]L = \frac{J.K^{2} }{F}[/tex].
Select an appropriate unit for number of laughs:
(jokes*knowledge²) / familiarity
familiarity / (jokes*knowledge²)
familiarity² / (jokes*knowledge)
(jokes*knowledge) / familiarity²
Answer: Unit for number of laughs is (jokes*knowledge²) / familiarity
Step-by-step explanation: Number of laughs (L) is related to jokes (J), knowledge (K) and familiarity (F) according to the proportion: [tex]L = \frac{J.K^{2} }{F}[/tex]
The unit for L will be: L = (jokes.knowledge²).familiarity⁻¹
or
L = [tex]\frac{jokes*knowledge^{2} }{familiarity}[/tex]
PLEASE HELP 10 POINTS WILL GIVE BRAINLIEST: Which geometric solid is the best model for the head of a human being?
A. Cylinder
B. Cone
C. Pyramid
D. Sphere
Answer:
sphere
Step-by-step explanation:
Human heads are close to circles and sometimes are circles
Sphere is the best model for the head of a human being.
A human head definitely doesn't represent a Cone neither a Pyramid.
Now a cylinder is a solid which is circular at its edges and straight in its length which clearly does not model the human head. Now the Sphere, it does closely represent the outside figure of a human head.
Thus Sphere is the best model for a human head.
Therefore option D, sphere is the correct answer.

2. The cone has a radius of 30 mm and slant height of 34 mm. What is the height h for this cone?
Answer:
h = 16
Step-by-step explanation:
By applying the Pythagorean Theorem, the slant height is given by the formula:
[tex]\sqrt{r^2+h^2}[/tex]
34 = [tex]\sqrt{30^2 + h^2}[/tex]
[tex]34^2 = 30^2 + h^2[/tex]
[tex]1156 = 900 + h^2[/tex]
[tex]256 = h^2[/tex]
[tex]h = \sqrt{256}[/tex]
[tex]h = 16[/tex]
The diameter of a circle measures 24 mm. What is the circumference of the circle? use 3.14 for π, and do not round your answer.
Answer & Step-by-step explanation:
[tex]Circumference=d\pi[/tex]
The diameter of the circle is 24 mm. So, let's add in the diameter and find the circumference of the circle.
[tex]Circumference=(24)\pi[/tex]
We will use 3.14 for pi.
[tex]Circumference=75.36[/tex]
So, the circumference of the circle is 75.36 mm.

What is the y-intercept of the line with equation y = 3x + 2
Answer:
The y-intercept is 2.
Step-by-step explanation:
We can find the y-intercept by looking at the linear equation y = mx + b.
m = slope
b = y-intercept
====================================================
Let's find the y-intercept of this line.
You should notice that the equation is written in Slope-Intercept Form:
[tex]\bigstar{\boxed{\pmb{y=mx+b}}}[/tex]
Where
m -> slope
b -> y-intercept
In the equation y=mx+b, the y-intercept is b, and in the equation y=3x+2, 2 is the y-intercept.
=========================================================
