The constant of proportionality of the proportional relationship between the number of wagon loads, x and the number of bales of hay Dwayne can haul, y, is given as follows:

4.

The standard definition of a proportional relationship is given as follows:

y = kx.

Hence the solution for the constant is given as follows:

k = y/x.

As the table represents a proportional relationship, the constant can be calculated from any pair, hence:

k = 20/5 = 4.

Answer:

  5 + 8 = 45

Step-by-step explanation:

We observe that the sequence of numbers on the left is arithmetic, with each value increasing by 1 from each expression to the next.

Similarly, we observe that the sequence on the right increases by an increasing amount from one number to the next. First differences are 7, 9, suggesting that each successive line in the table will differ by 2 more than the previous two lines did.

Following this pattern, we have ...

  4 + 7 = 32

  5 + 8 = 45

_____

Additional comment

Here, it seems, the symbol "+" in the expression "a+b" is intended as a stand-in for the function f(a, b). That is, we're given three expressions ...

  f(1, 4) = 5

  f(2, 5) = 12

  f(3, 6) = 21

and asked to predict the value of f(5, 8).

f may be any of a variety of functions. A couple of them are ...

  f(x, y) = x^2 +4y -12

  f(x, y) = y^2 -2x -9

or ...

  f(n, n+3) = n(n+4), which could also be written f(x, y) = x(y+1)

To find the circumference from the diameter, you need to multiply the diameter by pie (3.14)

Answer:

21.99 or just round to 22

Step-by-step explanation:

Radius is 3.5

Diameter is 7

Circumference is 21.99

Answer:

1st Circle

Radius = 3.5

Diameter = 7

Circumference = 2 × [tex]\pi[/tex] × r = 2 × 3.14 × 3.5 = 21.98

2nd Circle

Radius = 9

Diameter = 18

Circumference = 2 × [tex]\pi[/tex] × r = 2 × 3.14 × 9 = 56.52

Answer:

AB= [tex]\sqrt(5-1)^2 +(2+1)^2 = \sqrt16+9 =5[/tex]

BC= [tex]\sqrt(5-9)^2 + (2-5)^2 = \sqrt16+9=5[/tex]

AC = [tex]\sqrt(1-9)^2 + (-1-5)^2 = \sqrt64+36 = 10[/tex]

So, AC = AB + BC

Answer:

a) 0.0828 = 8.28% probability that a randomly selected student is in a high-level English class and has been bullied

b) 0.12 = 12% probability that a randomly selected student is in a music class and has been bullied

c) 0.0276 = 2.76% probability that a randomly selected student is in a music class, has been bullied, and is in a high-level English class

Step-by-step explanation:

Probabilities of independent events happening together:

The probabilities of independent events happening together is the multiplication of the probabilities of each event happening.

In this question:

0.23 probability that a student is taking a high-level English class.

0.36 probability that a student has been bullied.

1/3 = 0.3333 probability that a student is in music class.

(a) What is the probability that a randomly selected student is in a high-level English class and has been bullied?

0.23*0.36 = 0.0828

0.0828 = 8.28% probability that a randomly selected student is in a high-level English class and has been bullied

(b) What is the probability that a randomly selected student is in a music class and has been bullied?

0.36*1/3 = 0.12

0.12 = 12% probability that a randomly selected student is in a music class and has been bullied

(c) What is the probability that a randomly selected student is in a music class, has been bullied, and is in a high-level English class?

0.23*0.36*1/3 = 0.23*0.12 = 0.0276

0.0276 = 2.76% probability that a randomly selected student is in a music class, has been bullied, and is in a high-level English class

Answer: 38.8

Step-by-step explanation:

Variation factor k = 1/3

New volume when the base (area) is 8inches^2 and the height is 12inches is 32 in3

Step-by-step explanation:

As we know,  

The volume of cylinder (V) is given by πr²h  

Here  πr² = base area and h is the height of the cylinder

V ∞ πr²h

V = kπr²h  

Substituting the given values, we get  

40 = 6 x 20 x k

40 = 120k and

k   = ⁴⁰/₁₂₀

    = ¹/₃.

Volume when base area = 8in² and h = 12 inch

V = 8 x 12 x ¹/₃

V = 32in³

Step-by-step explanation:

Scale factor is 11.39 and ratio is 729:64

The scale factor is a measure for similar figures, who look the same but have different scales or measures.

volume of two similar spheres are 128m³ and 1458m³.

Scale factor= volume of sphere 1/ volume of sphere 2

= 1458/128

= 729/64

= 11.39

and the ratio = 729 : 64
