Answer:

Therefore, 448 inches² Wrapping paper is needed to wrap a present.

Step-by-step explanation:

The Present Shape as per dimensions it is CUBOID

Given:

Length = 8 inches

Width = 8 inches

Height = 10 inches

To Find:

Surface Area of Cuboid = ?

( Wrapping paper is needed to wrap a present )

Solution:

By Formula we have

$\textrm{Surface Area of Cuboid}= 2(Length\times Width +Width\times Height + Height\times Length)$

Substituting the given value in above formula we will get

$\textrm{Surface Area of Cuboid}= 2(8\times 8 + 8\times 10 + 10\times 8)\\\\\textrm{Surface Area of Cuboid}= 2(224)\\\\\textrm{Surface Area of Cuboid}= 448\ inches^{2}$

Therefore, 448 inches² Wrapping paper is needed to wrap a present .

11. What is the length of the missing side, x?

Dimas [21]

Answer:

x = 40 in

Step-by-step explanation:

the missing angle in the triangle on the left is

180° - (74 + 51)° = 180° - 125° = 55°

the missing angle in the triangle on the right is

180° - (74 + 55)° = 180° - 129° = 51°

the 2 triangles have 3 pairs of congruent angles and are therefore congruent.

Corresponding sides and angles are then congruent

consider the corresponding sides opposite 74° , that is x and 40 in , so

x = 40 in

Planet X has a mass of 8.46 x 1022 kg. Planet Y has a mass of 5,028,000,000,000,000,000,000,000 kilograms. How many times the ma

kramer

Answer:

59.4 times greater to the nearest tenth.

Step-by-step explanation:

5,028,000,000,000,000,000,000,000

= 5.028 * 10^24

So the required ratio = 5.028 * 10^24 / 8.46 * 10^22

= 0.594326 * 10^2

= 5.94326 * 10

= 59.4326.

What are the possible values of x if (4x - 5)2 = 49? Check all that apply.<br> uw we we

kogti [31]

Answer:

x = - $\frac{1}{2}$ , x = 3

Step-by-step explanation:

Given

(4x - 5)² = 49 ( take the square root of both sides )

4x - 5 = ± $\sqrt{49}$ = ± 7 ( add 5 to both sides )

4x = 5 ± 7, thus

4x = 5 - 7 = - 2 ( divide both sides by 4 )

x = $\frac{-2}{4}$ = - $\frac{1}{2}$

4x = 5 + 7 = 12 ( divide both sides by 4 )

x = 3

As a check

Substitute these values into the left side of the equation and if equal to the right side then they are the solutions.

x = - $\frac{1}{2}$

left side = (- 2 - 5)² = (- 7)² = 49 = right side ⇒ solution

x = 3

left side = (12 - 5)² = 7² = 49 = right side ⇒ solution

Tcecarenko [31]

Answer:

12.1x+t

Step-by-step explanation:

since we do not get a specific amount we must add 4.8 and 7.3 and substitute the amount the driver earns per mile with x and use t as a variable if they charge something like $5 just to get in before driving
