Given:
The equation that represents the relation between degrees Fahrenheit, F, and degrees Celsius, C.
[tex]F=\dfrac{9}{5}C+32[/tex]
To find:
Whether it is a proportional relationship or not.
Solution:
If y is proportional to x, then
[tex]y\propto x[/tex]
[tex]y=kx[/tex]
where, k is constant of proportionality.
It means, the proportional relationship is in the form of [tex]y=kx[/tex] and (0,0) satisfy it.
We have,
[tex]F=\dfrac{9}{5}C+32[/tex]
Put C=0 and F=0.
[tex]0=\dfrac{9}{5}(0)+32[/tex]
[tex]0=0+32[/tex]
[tex]0=32[/tex]
This statement is not true because [tex]0\neq 32[/tex].
Since, (0,0) did not satisfy the equation [tex]F=\dfrac{9}{5}C+32[/tex], therefore, the given equation is not a proportional relationship.

ANSWER: FG = 69
FG = FK + KG
KG = 1/2(FK)
FK = 46
RULE: When it comes to centroids, the longer section of the line is always 2/3 of the entire line (+ the shorter section of the line is always 1/3). This means that the shorter section of the line is HALF of the longer section of the line.
FG = FK + KG
FG = 46 + 46/2
FG = 46 + 23
FG = 69
CHECK:
FK = 2/3(FG)
46 = 2*69/3
46 = 138/3
46 = 46 ✔️
or
KG = 1/3(FG)
1/2(FK) = 1/3(FG)
46/2 = 69/3
23 = 23 ✔️
Can somebody help please :)
Answers
Answer:
the answer would be b
Step-by-step explanation:
You need to get the x alone, so you have to subtract 10 from both sides. The step after that would be to divide 2 from both sides.
Hope this helps! :)
Answer: 2x = -25.
Reason: Since this is an equation, you need to get x by itself. (Unless Slope Intercept form) So, you subtract 10, and add it to the other side, and you get 2x = -25. I hope this helps, and stay safe! :)

Answer:
B) -31
A) ellipse
Step-by-step explanation:
In the form ...
Ax² +Bxy +Cy² +Dx +Ey +F = 0
The discriminant is ...
B² -4AC
The interpretation is ...
< 0 ⇒ ellipse, possibly a circle= 0 ⇒ parabola> 0 ⇒ hyperbola
Any of the figures may be degenerate.

Here, the discriminant is ...
5² -4(-2)(-7) = -31
The equation represents an ellipse.
Which list shows the numbers in order from least value to greatest value
Answers
The answer is H
Explanation: what I did was change all of the numbers into decimal form so that we can compare them easier, -2 1/2= -2.5, -2.47 stays the same, -2/5 becomes positive .4 because the entire fraction is negative, you can look at it like -2/-5 and a negative divided by a negative is a positive, And then 5 stays a 5, And 21/4 equals 5.25 therefore your answer is H
Oh and by the way if you don’t know how to turn a fraction into a decimal you simply divide the top number by the bottom number for example 1/2 you take 1 and divide it by 2 which gives you .5 or 12/13 = .923076 hope this makes sense and that this helped
in the right ABC with C=90,A=75 and AB=12cm. Find the area of ABC
Answers
Answer:
18 cm^2
Step-by-step explanation:
The legs of a right triangle are the base and height of the triangle.
Since C is a right angle, AB is the hypotenuse.
AC and BC are the legs and the base and height.
sin 75 = BC/12
BC = 12 sin 75
cos 75 = AC/12
AC = 12 cos 75
area = bh/2 = (12 sin 75)(12 cos 75)/2
area = 18 cm^2
A math class has 14 female students. Out of 24 total students, what is the probability what is the probability of randomly selecting a male student? **Reduce/Simplify**
Answers
Answer:
[tex] \frac{5}{12} [/tex]
Step-by-step explanation:
[tex]P(male \: student) \\ = \frac{number \: of \: male \: students}{total \: number \: of \: students} \\ = \frac{24 - 14}{24} \\ = \frac{10}{24} \\ = \frac{5}{12} [/tex]
Alternatively,
P(male student)
= P(not female)
= 1 -P(female)
[tex] = 1 - \frac{14}{24} \\ = 1 - \frac{7}{12} \\ = \frac{5}{12} [/tex]
☆P(event) is the probability of an event happening. The probability of an event not happening is 1 - probability of the event happening.

Answer:
37°
Step-by-step explanation:
ΔOPQ extended trough Q to R
m∠PQR = (7x-19)° -is an exterior angle to the triangle
m∠OPQ = (2x-3)° -angle inside the triangle
m∠QOP = (x+16)° -angle inside the triangle
m∠PQR = ?
m∠PQR = m∠OPQ + m∠QOP
7x-19 = 2x-3 +x+16
7x -2x-x = 16-3+19
4x = 32
x=32/4=8
m∠PQR = 7x-19 = 7*8-19 =56 -19= 37°

x=10
Step-by-step explanation:
First square root 36 cm^2
Then you square both 8 and 6
Then you square root the sum of the two numbers.
This is called Pythagorean Theorem, which can be shown as a^2 + b^2 = c^2
x=10cm. you will have to use the pythagorean theorem in order to find the hypotenuse of that triangle. 6^2•8^2=100. square root of 100=10. x=10
Choose the best score on a quiz. 24 points out of 42 24 points out of 42 75 points out of 135 75 points out of 135 150 points out of 250 150 points out of 250 75 points out of 150
Answers
Answer:
150/250
Step-by-step explanation:
24/42, 75/135, 150/250, and 75/150 I believe is what you're asking. We know 75/135 is better than 75/150 so 75/150 is out of the equation. If we multiple 75/135 by 2 we get 150/270 which is more than 150/250, so 75/135 is out of the equation. Now to compare 24/42 and 150/250 we can divide their fractions, if we divide 24/42 we get 0.57, so 57%. If we did 150/250 we get 0.6 or 60%. So 150/250 is the best score.
Answer: 150 out of 250
Step-by-step explanation:
24 out of 42 is 57.14
75 points out of 135 is 55.56
150 out of 250 is 60%
75 out of 150 is 50%
A hummingbird lives in a nest that is 9 meters high in a tree. The hummingbird flies 9.4 meters to get from its nest to a flower on the ground. How far is the flower from the base of the tree?
Answers
Answer: Distance of flower from the base of the tree = 0.4 meters
Step-by-step explanation:
Given: A hummingbird lives in a nest that is 9 meters high in a tree. The hummingbird flies 9.4 meters to get from its nest to a flower on the ground.
Distance of flower from the base of the tree = 9.4 meters - 9 meters
= 0.4 meters
Hence, Distance of flower from the base of the tree = 0.4 meters

Chris is saving money to buy a new bike that costs $189. He has saved $99 so far. He plans on saving $10 each week. In how many weeks will Chris have enough money to buy the new bike?
Answers
Answer:
he will have the money in 9 weeks
99+10+10+10+10+10+10+10+10+10=189
Answer: It'll take Chris 9 weeks to have enough money to buy the new bike. w = 9
Step-by-step explanation:
Hey there! If you have any questions please feel free to ask them in the comments.
We can write down the formula for this problem as:
$189 = $99 + $10w
$189 is the total amount of money Chris needs, and $99 is the amount of money Chris already has. $10w would be $10 per week in which Chris will have enough money to buy the new bike.
Steps: Solve for W
$189 - $99 = $99 - $99 + $10w
$90 = 0 + $10w
$90 = $10w
[tex]\frac{90}{10}[/tex] = [tex]\frac{10w}{10}[/tex]
[tex]\frac{90}{10}[/tex] = w
9 = w
Answer: w = 9
