The Roster form of { 8,12,16 } is {X;X=4k ,k ∈ (2,34)}

Roster form:

A set's roster notation is a straightforward mathematical representation of the set. The elements (or members) of a set are listed in a row inside the curly brackets in the roster form. If the set contains more than one element, each pair of elements is separated by a comma symbol. Because the enumeration is done one by one, the roster form is also known as the enumeration notation.

Given a set in a set builder form i.e.{ 8,12,16 } and asked to convert into Roster form

Roster form of { 8,12,16 } ={X;X=4k, k ∈ (2,34)}

Therefore,The Roster form of { 8,12,16 } is {X;X=4k, k∈ (2,34)}

Which equation can be used to find the surface area of the cylinder?

sergij07 [2.7K]

Answer:

S = 2π(36) + 2π(6)(8)

S = 2(3.14)(36) + 2(3.14)(6)(8)

Step-by-step explanation:

The surface area of a cylinder is the sum of the area of the base and the lateral area. A cylinder has 2 circular base .

Surface area = 2πr² + 2πrh

surface area = 2πr(r + h)

where

r = radius

h = height

surface area = 2πr(r + h)

r = 6 cm

h = 8 cm

The equation to find the surface area is represented below.

Surface area = 2πr² + 2πrh

S = 2π (6²) + 2π (6)(8)

S = 2π(36) + 2π (6)(8)

Assuming π is given as 3.14 the equation will be as follows

S = 2(3.14)(36) + 2(3.14)(6)(8)

A single carton of juice costs $4.20. A special offer pack of 3 cartons costs $9.45. Ali bought a special offer pack instead of

fgiga [73]

1 cartons of juice = $4.20

3 single cartons = 4.20 * 3 = $12.60

1 pack = $9.45

He saved 12.60 - 9.45 = $3.15

So, he saved $3.15, compared to the total ($12.60)

To calculate the percentage, we will do a proportion:

3.15 (money saved) : 12.60 (total of 3 single cartons) = x (how much percentage) : 100 (total)

3.15 : 12.6 = x : 100

To calculate x, we will moltiplicate the ends (where we have known numbers) than divide all per 12.6

x = (3.15 * 100) / 12.60 = 315 / 12.6 = 25

So the percentage saving is 25%

Answer:

simple, it's (4,4) because the (-4,-4) is on the left side then on the right side, we know the x axis is positive right? so then you know that the bottom of the y axis is negative and the x axis is first in the coordinate and so the first one is positive now.

Refer the diagram at the right. identify each angle pair as adjacent, vertical, or neither 7-12

Oxana [17]

Adjacent angles are angles that are side by side (right next to each other). They share a side. #7 and 11 are pairs of adjacent angles.

Vertical angles are angles that are directly across from each other. They are the same angle. #8 and 9 are vertical angles.

#10 and 12 do not fit either of these descriptions so they are neither.

dr. glock had an average balance of $400 on her credit card account for one year. She paid 1.75% interest per month. how much

Mariana [72]

x = interest paid altogether

400 + 400(0.175) = x

The 400 comes from the average balance. 400(0.175) comes from the interest she has to pay each month. 1.75% as a decimal is 0.175. It's multiplied since she pays 1.75% of the average balance.
