Answer:

see below

Step-by-step explanation:

The volume of a cylinder is given by

V = pi r^2 h

We can find the radius from the diameter

r = d/2 = 34/2 = 17

V = (3.14) (17)^2 * 27

V =24501.42 m^3

The surface of a cone is found by

SA = pi r^2 + pi r  l where l is the slant height

We can find the radius from the diameter

r = 8/2 = 4

SA =(3.14) * 4^2 + 3.14 * 4*7

      =50.24+87.92

        138.16 in^2

The lateral surface area of a pyramid is found by taking the area of the sides

LSA = 4 * the area of a triangle

          we multiply by 4 since there are 4 sides

        = 4 * 1/2 b*h  where b is the base of the triangle and h is the height of the triangle.  (in this case it would be the slant height)

           = 2 * 8 *22

          =352 m^2

I NEED HELP PLEASE!<br><br> If you can help me with this you amazing!<br><br> Thank you

Answer:

a=-3

Step-by-step explanation:

we have

a-2=\frac{3+6a}{3}

Solve for a

That means ----> Isolate the variable a

Factor 3 in the numerator right side

a-2=\frac{3(1+2a)}{3}

Simplify right side

a-2=1+2a

subtract a both sides

a-2-a=1+2a-a

-2=1+a

subtract 1 both sides

-2-1=1+a-1

-3=a

Rewrite

a=-3

Find the sum of a finite arithmetic sequence from n = 1 to n = 10, using the expression 3n − 8.
maw [93]

Answer:

The answer is 85

Step-by-step explanation:

The equation used to find the sum of an arithmetic series is: (n/2) * (a1 + an).

n in this case is 10 (the number of numbers in the series)

an is 22 (plug in 10 to the expression 3n-8)

and a1 is -5 (plug in 1 to the expression 3n-8)

so when you plug everything in to the final equation, you get

(10/2) * (-5 + 22)

5 * 17

85

Answer:

x=8

Step-by-step explanation:

When trying to figure this out, you may see that x might be 8. Since the angels are all 120 degrees and equal up to 360 degrees (full size,) x will equal 8.

A salesperson's commission rate is 4%. What is the commission from the sale of $32,000 worth of furnaces? Use pencil and paper.
Delvig [45]

Answer:

Step-by-step explanation:

commission from sale of $32,000 = $32,000 x 4% = $1,280

Suppose sales would double, comission would be doubled too.

Assume sales be S and commission be C

C = S * 4% (they have a linear positive relation)

if S double to 2S, new commission = (2S)*4% = 2*(S*4%) = 2 (old commission)
