Which table of ordered pairs represents a proportional relationship?
Whoever answers correctly and first-will be marked brainiest :)

If the cylinders are made out of wood that costs $11.07 per cubic foot, the cost of the cylinder will be $782.10

The volume of a cylinder is expressed as:
V = πr²h

h is the height = 40ft

r is the radius  = 1.5/2 = 0.75ft

Substitute:

V = π(0.75)²(40)
V = 3.14 * (0.75)²(40)

V = 70.65 cubic foot

If the cylinders are made out of wood that costs $11.07 per cubic foot, the cost of the cylinder will be 11.07 * 70.65 = $782.10

Answer:

  6 feet

Step-by-step explanation:

The circumference is given by ...

  C = 2πr

Since we travel that distance in 3 seconds, our speed is ...

  2πr/3 = 12.56 . . . . . . feet per second

  6.28/3r = 12.56 . . . . using 3.14 for π

  r = 12.56(3/6.28) = 6

The radius of the merry-go-round is 6 feet.

The change in the current price of the bond when the market interest rates increase from 5% to 5.5% is a fall in the price of the bond.

The attractiveness of bonds occurs when the interest rates fall.  This fall drives up demand for bonds with fixed interest rates and the increasing demand causes bond prices to rise.

This implies that when interest rates rise, investors do not prefer the lower fixed interest rate paid by a bond.  The reduced demand for bonds results in their declining prices.

Thus, when interest rates rise, bond prices fall and when interest rates fall, bond prices rise.

The probability model shows the distribution of people of age 20 to 39 years

The value of the probability P(A) is 0.631

From the question, the notation P(A) represents the probability that a person is either 20-24 years old or is married

From the table, we have the following parameters:

The probability, P(A) is then calculated as:

P(A) = P(20-24) + P(Married) - P(20-24 and Married)

Substitute known values

P(A) = 0.26 + 0.398 - 0.027

Evaluate the expression

P(A) = 0.631

Hence, the value of the probability P(A) is 0.631

Answer:

[-8, infinity)

Step-by-step explanation:

Interval notation uses (, [, ], ) where the parentheses are exclusive and the brackets are inclusive. That means, we have:

[-8, infinity)

The reason we don't use the square bracket for infinity is because you can never include infinity in your set

Answer:

{x,y} = {1,1}

Step-by-step explanation:

[2]    6y = -14x + 20

 [2]    y = -7x/3 + 10/3

// Plug this in for variable  y  in equation [1]

  [1]    -10x - 6•(-7x/3+10/3) = -16

  [1]    4x = 4

// Solve equation [1] for the variable  x

  [1]    4x = 4

  [1]    x = 1

// By now we know this much :

   x = 1

   y = -7x/3+10/3

// Use the  x  value to solve for  y

   y = -(7/3)(1)+10/3 = 1

Solution :

{x,y} = {1,1}

Answer:

The dependent variable is distance, the equation is y = 33x, and the dragonfly will travel 792 miles

Step-by-step explanation:

ordered pairs:  (0, 0)  (2, 66)  (4, 132)  (6, 198)

slope of linear equation = change in y ÷ change in x

⇒ slope = (132 - 66) ÷ (4 - 2) = 33

Therefore, equation of the line: y = 33x

When x = 24, y = 33 × 24 = 792 miles

Distance is dependent on time, therefore distance is the dependent variable and time is the independent variable.

Answer:

94a - 32b - 72c + 560

Step-by-step explanation:

First get the product of 6(3a + 12b - 4c) = 18a + 72b - 24c.

Second get the sum of 14a + 70 and 5b - 12c = 14a + 5b - 12c + 70 then multiply by 8 and the product is 112a + 40b - 96c + 560. Subtract the first product from the 2nd product to get the final answer

Answer:

  x + 2.6 = 10.4

  x = 7.8

Step-by-step explanation:

If 2.6 liters are added to x liters with the result that 10.4 liters then exist, the model is ...

  2.6 +x = 10.4 . . . . . . . 2.6 added to x gives 10.4

The commutative property of addition lets you rewrite this to ...

  x +2.6 = 10.4

__

Subtracting 2.6 from both sides of the equation gives its solution:

  x +2.6 -2.6 = 10.4 -2.6

  x = 7.8

Answer:

x+47+85+54=180°

x+186°=180

x=-6

Substitute the value of x in x+47

-6+47=41°

Your answer is 41°
