Answer: 95 feet

Step-by-step explanation:

Let the length of the horizontal run be represented by x.

Slope Grade = (Rise/Run) × 100

20 = (19/x) × 100

20 = 1900/x

20x = 1900

x = 1900/20

x = 95

Therefore, the length of the horizontal run must be 95 feet

Answer:

r=2.9cm

Step-by-step explanation:

we know the formula, mass= density*volume

as a result we can figure out the volume = mass/density

=485/8 cm^3

=60.625cm^3

here comes another formula of volume of cone = $\frac{1}{3}$ $\pi$ $r^{2}$ $h^{}$

we will use this to find the radius,

$\frac{1}{3}$ $\pi$ $r^{2}$ $h^{}$ =60.625

$\pi$ $r^{2}$ $h^{}$ =181.875

h is 70mm which we will turn to 7cm

$\pi$ $r^{2}$ *7=181.875

$r^{2}$ =8.27

r=2.875825cm

r=2.9cm

nice question. hope this helps
