Answer:
[tex]q = 34[/tex] when [tex]p = 2[/tex].
Step-by-step explanation:
Variables [tex]p[/tex] and [tex]q[/tex] ([tex]p \ne 0[/tex], [tex]q \ne 0[/tex]) are inversely proportional to one another if one variable- for example, [tex]p[/tex]- is proportional to the reciprocoal of the other variable- [tex](1/q)[/tex].
In other words, if [tex]p[/tex] and [tex]q[/tex] ([tex]p \ne 0[/tex], [tex]q \ne 0[/tex]) are inversely proportional to one another, there would exist a constant [tex]k[/tex] ([tex]k \ne 0[/tex]) such that:
[tex]\displaystyle p = k\times \left(\frac{1}{q}\right)[/tex].
The value of [tex]k[/tex] is constant and is independent of [tex]p[/tex] and [tex]q[/tex]. Given that [tex]p = 17[/tex] when [tex]q = 4[/tex], rearrange the equation above to find the value of [tex]k\![/tex]:
[tex]k = p\, q = 68[/tex].
Rewrite the equation again to find [tex]q[/tex] in terms of [tex]k[/tex] (which doesn't change) and [tex]p[/tex] (which might change):
[tex]\begin{aligned}q &= \frac{k}{p}\end{aligned}[/tex].
Since [tex]k = 68[/tex], given that [tex]p = 2[/tex], the value of [tex]q[/tex] would be:
[tex]\begin{aligned}q &= \frac{k}{p} \\ &= \frac{68}{2} = 34\end{aligned}[/tex].

how to find area of triangle
Answer:
[tex]\displaystyle A =\frac{B*H}{2}[/tex]
Step-by-step explanation:
To find the area of a triangle, we can use the formula of:
[tex]\displaystyle A =\frac{B*H}{2}[/tex]
This formula comes from the area of a rectangle, because a triangle is half a rectangle.
How to find the area of a triangle?
❒ Explanation -:Triangle :
A polygon which has three sides is called a triangle.
Formula :
Assume a rectangle ABCD and let the height be h and base be b.
If we draw a diagonal from one vertex, it will break the rectangle into two congruent or equal triangles. The area of each triangle is half the area of the rectangle.
The area of the triangle ABC is [tex]\dfrac{1}{2}[/tex] × base × height.
[tex] \star \small\boxed{ \rm{ Area \: of \: a \: triangle = \dfrac{1}{2} × Base × Height}} [/tex]
This formula comes from the area of a rectangle. A triangle is half as big as the rectangle that surrounds it, that is why the area of a triangle is one-half base times height.

i need the equation and it solved
Answer:
Option ASpeed of plane is 240 km/h, speed of wind is 50 km/hStep-by-step explanation:
With the tail wind the total speed is the sum of the speeds of plane and wind.
When into wind the total speed is the difference of speeds of plane and wind.
The first equation is
(r + w)*6 = 1740The second equation is
(r - w)*3 = 570Simplify both equations and solve the system
r + w = 1740/6 ⇒ r + w = 290r - w = 570/3 ⇒ r - w = 190Solve by elimination, add up the equations
r + w + r - w = 290 + 1902r = 480r = 240Find the value of w
240 + w = 290w = 290 - 240w = 50The length of a rectangle is 2 centimeters less than five times the width of a rectangle. The area of the rectangle is 16 square centimeters. Find the length and width of the rectangle.

A valuable watch has an original price of $x. It is sold for $5304 after its original price has been increased by 2% and then by 4%. Find x.
SHOW YOUR WORKING.
Answer:
$5416.67
Step-by-step explanation:
If A valuable watch has an original price. It is sold for $5304 after its original price has been increased by 2% and then by 4%. The original price of watch is 5096.
What is Percentage?percentage, a relative value indicating hundredth parts of any quantity. One percent (symbolized 1%) is a hundredth part
let the original price be x.
The selling price of watch is $5304 .
2% of $5304 is 2/100×5304=0.02×5304
=106.08
Now let us remove the 2% from the selling price of the watch.
$5304 - 106.8 =5197.2
4% of $5197.2 is 4/100×5197.2=0.04×5197.2
=207.888
So Selling price of watch minus percentage in increase is the original price
5304-207.888=5096.1
Hence if a valuable watch has an original price. It is sold for $5304 after its original price has been increased by 2% and then by 4%. The original price of watch is 5096.

∠1 and ∠2 are linear pair. If m∠1 = 3x + 4 and m∠2 = 2x – 9, find x.
Answer:
37
Step-by-step explanation:
Linear pairs are supplementary (adds up to 180)
m∠1 + m∠2 = 180
3x + 4 + 2x - 9 = 180
5x - 5 = 180
5x = 185

Answer:
60
Step-by-step explanation:
You have the proper formula. You just need to swap some things around so we aren't solving for C. C is always the hypotenuse, the diagonal line opposite the right triangle. A and B can be either side unless specified.
1. The side we're solving for can either be called a or b. Let's call it A.
2. Now, switch around the theorem to solve for a: [tex]C^2-B^2=A^2\\[/tex]
3. Plug in what we know: [tex]8^2-2^2=a^2[/tex]
4. It simplifies down to [tex]60=a^2[/tex]
5. The "[tex]a^2[/tex] " means to square the a. We need to undo that to get a by itself. The opposite of squared is the square root
6. This leaves us to take the square root of both sides, which isolates a.
7. [tex]\sqrt{60}[/tex] is the answer. It's asking for it in the square root so we don't need to simplify it.

a sphere has a volume of 179.6 cubic cm which value is closest to the radius of this sphere in cm
The volume of the sphere is the amount of space in it, and the value closest to the radius is 3.5 cm
How to determine the radius of the sphere?The volume is given as:
V = 179.6
The volume is calculated using:
V = 4/3πr³
So, we have:
4/3πr³ = 179.6
Multiply both sides by 3/4
πr³ = 134/7
Divide both sides by π
r³ = 42.88
Take the cube root of both sides
r = 3.5
Hence, the value closest to the radius is 3.5 cm

The common difference is equal to 5.
A factory makes circular rugs with a radius of 3.5 feet. How much braid do they need to go all the way around the outside of the rug? Use 3.14 for pi
I believe that the answer is 21.48
The factory would need approximately a circumference of 21.98 feet of the braid to go all the way around the outside of the circular rug.
We have,
The formula for the circumference (C) of a circle is:
C = 2πr
where r is the radius of the circle and π is a mathematical constant approximately equal to 3.14.
In this case, the radius of the rug is 3.5 feet, so we can calculate the circumference as:
C = 2 × 3.14 × 3.5 = 21.98 feet
Therefore,
The factory would need approximately a circumference of 21.98 feet of the braid to go all the way around the outside of the circular rug.
