9514 1404 393

Answer:

  3.0

Step-by-step explanation:

The angle, its opposite side, and the hypotenuse are given. Then the relevant trig relation is ...

  Sin = Opposite/Hypotenuse

  sin(21°) = x/8.3 . . . . . . . . . . . . . . . . . . use the given values

  x = 8.3·sin(21°) ≈ 8.3×0.3584 . . . . . . multiply by 8.3

  x ≈ 3.0

A cube of side length s sits inside a sphere of radius r so that the vertices of the cube sit on the sphere. Find the ratio r :
svlad2 [7]

Answer:

r : s is √3 : 2

Step-by-step explanation:

The given parameter are;

A cube is inscribed in a sphere

The side length of the cube = s

The radius of the sphere = r

The ratio r : e = Required

It is noted that for a cube inscribed in a sphere, we have;

The diameter of the sphere = The diagonal of the cube

The diameter of the sphere, D = 2 × The radius = 2·r

The square of the diagonal of the cube, d² = s² + s² + s² = 3·s²

∴ The diagonal of the cube, d = (√3)·s

From the relationship between the cube and the sphere in which it is inscribed, (The diameter of the sphere = The diagonal of the cube), we have;

2·r = (√3)·s

∴ r/s = (√3)/2

r : s = √3 : 2.

Shelly paid $8.84 for a pizza. This amount includes a sales tax of 4%. What was the cost of the pizza before tax?
lorasvet [3.4K]

Answer:

$8.50

Step-by-step explanation:

let the price before tax be $x

given that the sales tax rate is 4%, hence the amount she paid in taxes

= 4% of x

= (4/100)x

= 0.04x

We can now build an equation for what she paid:

Amount Paid = price before tax + amount paid in taxes

8.84 = x + 0.04x

8.84 = 1.04x   (divide both sides by 1.04 and rearranging)

x = 8.84 / 1.04

x = $8.50
