Answer:

990, C

Step-by-step explanation:

The formula for the surface area of the bottom cushion is

A = 2wl + 2lh + 2hw (w is width, l is length, h is height)

w = 18, l = 21, h = 3

A = 2(18)(21) + 2(21)(3) + 2(3)(18)

A = 2(378) + 2(63) + 2(54)

A = 756 + 126 + 108

A = 990 (C)

Answer:

D. x < 3

Step-by-step explanation:

3x + 7 < 16

To solve, we have to isolate x.

3x + 7 < 16

Subtract 7 from both sides :

3x < 9

Divide 3 from both sides :

x < 3

Now in some cases, you could say that the inequality sign would switch, but this is only when you divide by a negative sign, so keep that in mind.

Answer:

3 3/4

Explanation:

30/8 is 3.75 which is equal to 3 3/4

or you can see that 8 goes into 30 completely 3 times and then you have 6/8 left over, which simplifies down to 3/4 because 6/2= 3 and 8/2= 4

Step-by-step explanation:

Egyptians were very well known to be very interested in Spirits and Gods.

Their whole dynasty was built on the dawn of their Gods. There were many, like the Greek and Roman Gods. One of the sun, one of the underworld....etc..

The pharaohs believed themselves to be god. (Due to their immense power)

Egyptians believed that after death there was an Afterlife. In that afterlife, there was games, other people (spirits), homes (graves). This might sound weird but in the graves especially of Pharaohs they placed beds, tables, chairs, games..etc..

The total volume of water in the pool is (6x² + 12x - 90) ft³.

Volume is a three-dimensional quantity used to calculate a solid shape's capacity. That means that the volume of a closed form determines how much three-dimensional space it can fill.

A fish tank, for example, is 3 feet long, 1 foot wide, and 2 feet tall. To calculate the volume, multiply the length by the breadth by the height, which is 3x1x2, which equals six.

Given:

The volume of water in the deep end can be represented by

= (2x² + 12x + 10) ft³

and, the volume of the water in the shallow end can be represented by (4x² −100) ft³.

The total volume of water in the pool  = ( 6x^3 + 12x^2 - 90x ) ft^3

So, The total volume of water in the pool

= volume of water in the deep + volume of the water in the shallow end

= (2x² + 12x + 10) + (4x² −100)

= 2x² + 4x² + 12x + 10 - 100

= 6x² + 12x - 90

The value of x is 17 unit.

The Pythagorean theorem, or Pythagorean theorem, illustrates the relationship between the three sides of a right-angled triangle. The square of the hypotenuse is equal to the sum of the squares of the other two sides of a triangle, according to the Pythagorean theorem.

We know,

Kyle held a balloon 8 feet off the ground.

Ava is standing 15 feet directly to the right of Kyle.

So, height = 8 ft and distance = 15 ft

Using Pythagoras theorem

x² = 8² + 15²

x² = 64+ 225

x = 17 unit

Thus, the value of x is 17 unit.

Values of the elements in the Matrix are A₂₁ = -2, A₂₂ = 0, A₂₃ = 4, A₃₃ = 5.

A collection of numbers lined up in rows and columns to form a rectangular array is called a matrix. The elements, or entries, of the matrix, are the integers. In addition to many other areas of mathematics, matrices have numerous applications in the fields of engineering, physics, economics, and statistics.

given, the sum of each row is equal to the sum of each column equals the sum of all diagonals.

Since, the sum of column C₁ = 3 + -2 + 1 = 2

the sum of Row R₁ = 3 + A₂₁ + 1 = 4 + A₂₁

Since this is equal to the sum of column C₁

thus, 4 + A₂₁ = 2

A₂₁ = -2

the sum of column C₂ = A₂₁ + A₂₂ + 4

C₂ = -2 + A₂₂ + 4

C₂ = A₂₂ + 2

Since this is equal to the sum of column C₁

2 = A₂₂ + 2

A₂₂ = 0

the sum of Row R₂ = -2 + A₂₂ + A₂₃

R₂ = -2 + 0 + A₂₃

Since this is equal to the sum of column C₁

2 = -2 + A₂₃

A₂₃ = 4

the sum of Row R₃ = -1 + 4 + A₃₃

R₃ = -3 + A₃₃

Since this is equal to the sum of column C₁

2 = -3 + A₃₃

A₃₃ = 5

therefore, the values of the matrix's elements are A₂₁ = -2, A₂₂ = 0, A₂₃ = 4, A₃₃ = 5.
