A two way table is a table in which both each column and row meet up to add up to a certain number. It could be used to find out the total number of people which like or dislike something.

(An example is shown in the attached file).

The inverse of a function is n(a) = (a+30)/3 option (A) is correct by using the concept of the inverse of a function.

<h3>What is a function?</h3>

It is defined as a special type of relationship, and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.

We have a function:

a(n) = 3n - 30

To find make subject n and solve

a(n) + 30 = 3n

$\rm n = \dfrac{a(n) + 30}{3}$

Plug n = n(a) and a(n) = a

$\rm n(a) = \dfrac{a + 30}{3}$

Thus, the inverse of a function is n(a) = (a+30)/3 option (A) is correct by using the concept of the inverse of a function.

Describe the possible lengths of the third side of a triangle given that the lengths of the other two sides are 5 and 12 units l

FrozenT [24]

Answer:

7<x<17

Step-by-step explanation:

a+b>x

5+12>x

17>x

5+x>12

x>7

12+x>5

x>-7 (ignore then since it is negative and you would use the one that makes the range smaller which is the one above)

How do i solve a quadratic equation like this

Ostrovityanka [42]

Answer:

Option D. {–7, 7}

Step-by-step explanation:

3n^2 = 147

First, divide both side 3

n^2 = 147/3

n^2 = 49

Next, rearrange the variables to one side of the equation as shown below:

n^2 — 49 = 0

n^2 — 7^2 = 0

The above is now difference of two squares. This can be solve by doing the following:

(n — 7)(n + 7) = 0

n — 7 = 0 or n + 7 = 0

n = 7 or n = —7

The volume of a cube is 36 cm3. What is the surface area of the cube, rounded to the nearest tenth of a cm2

alekssr [168]

Answer:

65.4 cm²

Step-by-step explanation:

The volume of a cuboid is calculated by multiplying the length, base, and height together. Since a cube has equal sides, the formula for the volume of a cuboid can be simplified as shown below.

Volume of cube

= side ×side ×side

= side³

Given that the volume is 36 cm³, let's find the length of each side.

side³= 36

Cube root both sides:

side= $\sqrt[3]{36}$

Total surface area of a cube is the sum of the surface areas of its 6 identical square faces.

Area of a square

= side ×side

= side²

Surface area of 1 face= $(\sqrt[3]{36})^2$

Total surface area

= $6(\sqrt[3]{36} )^2$

= 65.416 (5 s.f.)

= 65.4 cm² (nearest tenth)
