Answer:

272 square inches

Step-by-step explanation:

Given

[tex]l = 8[/tex] --- length

[tex]w = 2[/tex] --- width

[tex]h = 12[/tex] ---- height

Required

Determine the total surface area (SA)

This is calculated using:

[tex]SA = 2 * (lw + wh + lh)[/tex]

[tex]SA = 2 * (8*2+2*12+8*12)[/tex]

[tex]SA = 2 * 136[/tex]

[tex]SA = 272[/tex]

The total surface area is 272 square inches

Answer:

Permanent Magnets and Electromagnets: What are the Differences? A permanent magnet is an object made from a material that is magnetized and creates its own persistent magnetic field. ... An electromagnet is made from a coil of wire which acts as a magnet when an electric current passes through it.

Step-by-step explanation:

Electromagnets differ from regular magnets in that they require an electric current to generate a magnetic field.

Regular magnets, also known as permanent magnets, possess an inherent magnetic field due to the alignment of their atomic or molecular structure. They do not require an external power source.

On the other hand, electromagnets are made by wrapping a coil of wire around a magnetic core and passing an electric current through the wire. The electric current creates a magnetic field, and the strength of the magnetic field can be controlled by varying the current.

One key advantage of electromagnets is their ability to be turned on and off by controlling the electric current. This feature allows for a wide range of applications, such as in electric motors, generators, speakers, magnetic levitation systems, and more, where the magnetic field needs to be controlled or modulated. In contrast, regular magnets have a constant magnetic field that cannot be easily manipulated.

A) First, calculate the volume of cuboid A.

3x2x8 = 48 cm cubed

Cuboid B:

6x2xh = 48 cm cubed

Simplify:

12xh = 48 cm cubed

12x4 = 48 cm cubed

So, the height of cuboid B is 4 cm

B) Multiply the volume by 1,000:

4.5 L = 4,500 cubic cm

Answer:

In my opinion both of the lines are tangent.

Step-by-step explanation:

Because a tangent to a circle is a straight line which touches the circle at only one point. This point is called the point of tangency. The tangent to a circle is perpendicular to the radius at the point of tangency.

Volume = base area x tall

base area = π x (1.8in)²

base area = 10.179 in²

Volume = 10.179 in² x 6.7 in

Volume = 68.198 in³

the volume is 68.198 in³

Answer:

1st pic:

x = 60

y = 50

2nd pic:

y = 8

∠W = 28

∠Y = 128 degrees

∠X = 24

Step-by-step explanation:

first pic:

to find x, subtract 120 from 180 ⇒ 180 - 120 = 60

to find y, add 60 & 70 & subtract the sum from 180 ⇒ 180 - (60 + 70) = 50

2nd pic:

to find ∠Y, subtract 52 from 180:

180 - 52 = 128

to find y, use the following equation:

3y + 4y - 4 + 128 = 180

combine like terms:

7y + 124 = 180

subtract 124 from each side:

7y + 124 - 124 = 180 - 124

7y = 56

divide 7 on both sides:

[tex]\frac{7y}{7} = \frac{56}{7}[/tex]

y = 8

now we can find angles W and X

∠W = 4y - 4

we know that y = 8 so just substitute 8 for y

∠W = 4 x 8 - 4

∠W = 28

∠X = 3y

likewise, subtitute 8 for y

∠X = 3 x 8

∠W = 24

to check, add all angles and if they add up to 180, then its right:

24 + 28 + 128 = 180

180 = 180

Step-by-step explanation:

here's your solution

=> for first figure , (x + 120° ) = 180° [ linear pair]

=> x = 180° - 120°

=> x = 60°

=> now , we know sum of all angles of traingle = 180°

= >so, 60° + 70° + y = 180°

=> y= 180° - 130°

=> y = 50

now in figure second

=> 4y - 4 + 3y = 52° [ exterior angle equal to sum of two opposite interior

=> 7y - 4 = 52°

=> 7y = 52° + 4°

=> 7y = 56°

=> y = 56°/7

=> 8°

4. ≥ read '' greater than or equals to ''

5. ≤ read '' less than or equals to ''

2. 3 > 2 ( 3 is greater than 2 )

3. 2< 4  ( 2 is less than 4 )

4. 3 ≥ 2 ( 3 is greater than or equals to 2)

5. 2 ≤ 4 ( 2 is less than or equals to 4 )

One - step inequality :

Addition and Subtraction Properties of Inequality -

If a > b, then a + c > b + c

If a > b, then a − c > b − c

Multiplication and Division Properties of Inequality -

If a > b, then ac > bc, if c > 0

If a > b, then ac < bc, if c < 0

If a > b, then [tex]\frac{a}{c} > \frac{b}{c}[/tex], if c > 0

Subtract 3%, 74-2.22 = 71.78

The first and second polygons are exactly the same, the only difference is that the second is bigger! If we look right the first polygon is 4 cm and the second is triple which means that we will have to triple the area of ​​the First polygon to discover the area of ​​the second polygon!

if the first polygon is 4 cm long and the second 12 cm means that the second polygon has three times the area of ​​the first polygon!

[tex](4 cm.3=12 cm)\\A-10 cm^{2}.3=30 cm^{2}[/tex]

the second polygon has [tex]30 cm^{2}[/tex]  of area
