y is inversely proportional to x. when x=3,y=8. work out the value of y when x=8
Answer:
y = 3
Step-by-step explanation:
given y is inversely proportional to x then the equation relating them is
y = k/× ← k is the constant of variation
To find k use the condition y = 8 when x = 3
k = yx = 8 × 3 = 24
y = 24/× ← equation of variation
When x = 8, then
y = 24/8= 3

Answer: 20 meters
Step-by-step explanation:
Squares will have equal sides. Since the perimeter is all the sides added up together add 5+5+5+5 to get 20
Hope you have a lovely day!
Answer:
The answer is 20 meters.
Step-by-step explanation:
Since a square has 4 equal sides, and we know that one side of this square is 5 meters long, then we multiply 5 (meters) by 4 (sides).
5 × 4 = 20
The square is 20 meters long! I hope this helps! :)

K=1/2mv square root of 2
rearrange for m:
Answer: V = The square root of (2K/M)
We are starting with the formula: K = 0.5MV^2
Our first steps to isolate V would be to multiply by 2 and divide by M on both sides of the equation.
2K/M = V^2
Now, we just have to take the square root of both sides of the equation
The equation rearranged for m is [tex]m = (2K) / v^2[/tex].
This equation allows us to calculate the mass (m) when the kinetic energy (K) and the velocity (v) are known.
To rearrange the equation [tex]K = (1/2)mv^2[/tex] for m, we can follow these steps:
Step 1: Multiply both sides of the equation by 2 to remove the fraction:
[tex]2K = mv^2[/tex]
Step 2: Divide both sides of the equation by[tex]v^2[/tex] to isolate m:
[tex](2K) / v^2 = m[/tex]
Therefore, the equation rearranged for m is [tex]m = (2K) / v^2[/tex].
This equation allows us to calculate the mass (m) when the kinetic energy (K) and the velocity (v) are known.

yes or no?
Answer:
53.47

Find the arc length and area of a sector with radius r=13 inches and central angle theta =40 degrees
Answer:
The arc length and the area of the circle sector are approximately 9.076 inches and 58.992 square inches.
Step-by-step explanation:
Geometrically speaking, we determine the arc length ([tex]s[/tex]), in inches, and the area ([tex]A[/tex]), in square inches, of a circle sector by means of these formulas:
[tex]s = 2\pi\cdot \left(\frac{\theta}{360}\right)\cdot r[/tex] (1)
[tex]A = \pi \cdot \left(\frac{\theta}{360} \right)\cdot r^{2}[/tex] (2)
Where:
[tex]r[/tex] - Radius, in inches.
[tex]\theta[/tex] - Central angle, in sexagesimal degrees.
If we know that [tex]\theta = 40^{\circ}[/tex] and [tex]r = 13\,in[/tex], then the arc length and the area of the circle sector are, respectively:
[tex]s = 2\pi\cdot \left(\frac{40}{360} \right)\cdot (13\,in)[/tex]
[tex]s \approx 9.076\,in[/tex]
[tex]A = \pi \cdot \left(\frac{40}{360} \right)\cdot (13\,in)^{2}[/tex]
[tex]A = 58.992\,in^{2}[/tex]
The arc length and the area of the circle sector are approximately 9.076 inches and 58.992 square inches.

What is the height of the box?
inches
Answer:
6 inches.
Step-by-step explanation:
V = L * W * H
L = 14
W = 8
V = 672
h = ?
Solution
672 = 14 * 8 * h
672 = 112 * h
h = 672 / 112

Your business has two branch stores. The recent physical inventory reports that the merchandise value for each store is: Store A $750,000, and Store B $580,000. The merchandise book value for each store is: Store A $757,000, and Store B $600,000. What is the dollar amount of shrinkage for each store?
Answer: Store A: 7,000 Store B: 20,000
Step-by-step explanation:
The amount of shrinkage for store A is $7000 and for store B is $20000.
What is loss?"If the selling price of an item is less than the cost price, then the difference between the cost price and the selling price of an item is called the loss".
For the given situation,
The merchandise book value for store A = $757,000
The merchandise book value for store B = $600,000
Based on physical inventory reports,
The merchandise value for store A = $750,000
The merchandise value for store B = $580,000.
The amount of shrinkage determines the loss and it is calculated by taking the difference between the values.
Store A = [tex]757000-750000[/tex]
⇒ [tex]7000[/tex]
Sore B = [tex]600,000-580000[/tex]
⇒ [tex]20000[/tex]
Hence we can conclude that the amount of shrinkage for store A is $7000 and for store B is $20000.
