Answer:

33.16ft

Step-by-step explanation:

Sin 56° = x / 40ft

0.829 = x / 40ft

x = 40ft * 0.829

x = 33.16ft

Ralph owns the farmer’s silo shown. The silo is a cylinder with a half-sphere as the roof. He wants to fill it up with corn for

IgorC [24]

Answer:

Half-Sphere Volume = [( π •diam³) / 6] / 2

Cylinder Volume = ¼ • π • diam² • height

Cylinder height = 19 meters

Sphere diameter = 10 meters

Cylinder portion = ¼ • π • diam² • height

Cylinder portion volume = ¼ • π • 10² • 19

Cylinder portion volume = 1,492.26

Half-Sphere Volume = [( PI * 10^3) /6 ] / 2

Half-Sphere Volume = 261.80

Total Volume = 1,492.26 + 261.80 = 1,754.06 cubic meters

corn is $1.13 per cubic meter

total cost = 1,754.06 * $1.13 = 1,982.08

Answer is C 1,981.08

What is the equation used to find the nth term of the arithmetic sequence: -9, -4 1, 6, 11...

elena-s [515]

Answer:

a^n=-9+(n-1).5

Step-by-step explanation:

Arithmetic sequence=a+(n-1)d

a=-9

n=?

d=+5

Arithmetic sequence=-9+(n-1)5

=-9+5n-5

Collect like terms

-9-5+5n

-14+5n

So the final answer is

an=-9+(n-1).5

Answer:

$F)\displaystyle \: 100\pi{ x}^{8} {y}^{2} {z}^{ 6}$

Step-by-step explanation:

we are given r and the formula

we want to find the surface area of the shpare with the given r

to do so

we need our algebra skills

substitute the value of r:

$\displaystyle \: S = 4\pi( {5x}^{4} y {z}^{ 3} {)}^{2}$

recall law of exponent

$\displaystyle \: ({x}^{m} {)}^{n} \iff \: {x}^{mn}$

to simplify:

$\displaystyle \: S = 4\pi({ {5}^{2} x}^{4 \times 2} {y}^{1 \times 2} {z}^{ 3 \times 2} )$

simplify multiplication:

$\displaystyle \: S = 4\pi({ 25x}^{8} {y}^{2} {z}^{ 6} )$

distribute:

$\displaystyle \: S = 100\pi{ x}^{8} {y}^{2} {z}^{ 6}$

hence our answer is F
