Answer:

<h2>652 ft²</h2>

Step-by-step explanation:

Look at the picture.

It's a net of right rectangular prism.

We have three pairs of rectangles:

7ft × 8ft

7ft × 18ft

8ft × 18ft

The formula of an area of a rectangle l × w:

A = lw

Calculate the areas:

A₁ = (7)(8) = 56 ft²

A₂ = (7)(18) = 126 ft²

A₃ = (8)(18) = 144 ft²

The Surface Area :

S.A. = 2A₁ + 2A₂ + 2A₃

Substitute:

S.A. = 2(56) + 2(126) + 2(144) = 652 ft²

Fill in the gaps in this sequence: -8, -19, -30, _ , _.<br> (Geometric and arithmetic sequences)
gavmur [86]

-8, -19, -30, -49 , -60

<u>Step-by-step explanation:</u>

Here we have the following sequence :

-8, -19, -30, _ , _

  • First term of sequence is -8 .
  • Second term of sequence is -19 : -8-11 = -19
  • Third term of sequence is -30 : -19-11 = -30
  • Fourth term of sequence is : -30-11 = -49
  • Fifth term of sequence is : -49-11 = -60  

Following sequence was an AP( Arithmetic Progression ) with first term as -8 i.e. a = -8 and common difference d = -11 having general equation as : -8 -11n .

Given the expression :

(3\times{10}^3)\div3

We need to find 2/3 of the given

The value of the given expression will be :

\frac{3\times10^3}{3}=10^3

2/3 of the value of the result will be :

\frac{2}{3}\cdot10^3=\frac{2}{3}\cdot1000=\frac{2000}{3}=666\frac{2}{3}
