This composite figure is made of three identical cylinders that are connected together

Radius:3 Height:8

Answers

The surface are of a cylinder is

SA = 2πr2 + 2πrh

where:
r = radius
h = height

This formula comes from adding the areas of the surfaces of the cylinder. It has two flat circular faces and a rounded face.

If we cut the cylinder from the circular face symmetrically, the surface area for one piece will be

SA = 2[(πr2)/2] + (2πr/2)h + 2rh

We will have 2-half flat circular faces, a flat rectangular surface, and half of the rounded surface.

Simplify the SA formula.

SA = πr2 + πrh + 2rh
SA = r(πr + πh + 2h)

Substitute the values into this formula.

SA = 3(3π + 8π + (2*8))
SA = 3(11π + 16)
SA = 33π + 48
SA = 151.67 cm2

Since we have 2 pieces, multiply this result by 2.

2(151.67 cm2) = 303.34 cm2.

The total area is 303.34 cm2.

Which ordered pair would form a proportional relationship with the point graphed below?

Answers

Answer:

-10, 20 because -20, 40 divided by 2 = -10, 20

The ordered pair that would form a proportional relationship with the point (-20, 40) is given as follows:

(15, -30).

What is a proportional relationship?

A proportional relationship is a relationship in which a constant ratio between the output variable and the input variable exists.

The equation that defines the proportional relationship is a linear function with slope k and intercept zero presented as follows:

y = kx.

The slope k is the constant of proportionality, representing the increase or decrease in the output variable y when the constant variable x is increased by one.

The constant for this problem is given as follows:

k = 40/-20

k = -2.

Hence the equation is:

y = -2x.

When x = 15, the numeric value of the equation is given as follows:

y = -2(15)

y = -30.

Hence the point is:

(15, -30).

Solve for x
3/5 (x − 7/10)= −3 1/4
Enter your answer as a mixed number in simplest form.

Answers

Answer:

x = 11(13/14)

Step-by-step explanation:

3/5(x – 7/10) = -31/4

open the bracket:

3/5 * x – 7/10 = -31/4

3/5 * –7x/10 = -31/4

3/5 + 31/4 = 7x/10

(12+155)/20 = 7x/10

167/20 = 7x/10

cross multiply:

140x = 1670

x =1670/140

x = 11(130/140)

x = 11(13/14)

The value of x is 1/5.

What is Equation?

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides. LHS = RHS is a common mathematical formula.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given:

3/5 (x − 7/10)= −3 1/4

Now, Solving for x

3/5 ( x- 7/10 )= 13/4

x- 7/10 = -13/4 x 5/3

x- 7/10 = -65 /12

x= -65/12 + 7/10

x= 24/ 120

x= 1/5

hence, the value of x is 1/5.

The cost of having photos taken includes a sitting fee and $12 for each portrait. The cost of 3, 6, and 9 photos respectively is $51, $87, and $123. What is the sitting fee? Use units in your answer and round answer to the hundredths place, for example $2.35
plz help

Answers

Answer:

The sitting fee is 15 dollars

Step-by-step explanation:

1 - 12 x 3 = 36

2 - 51 - 36 = 15

3 - 12 x 6 = 72

4 - 87 - 72 = 15

Answer:

$15.00

Step-by-step explanation:

cost of photos = sitting fee + $12 per photo

Let the number of photos = x

Let the sitting fee = s

cost of photos = s + 12x

cost of 3 photos = $51

s + 12(3) = 51

s + 36 = 51

s = 15
