39¹/₅ or 39.2

<h3>Further explanation</h3>

<u>The Problem:</u>

  • 7 copies of the sum of 8 fifths and 4.
  • Write an expression to match, and then evaluate.

<u>The Process:</u>

Here are some early expressions that need attention.

  • 8 fifths is \boxed{\frac{8}{5}}
  • the sum of 8 fifths and 4 is \boxed{\frac{8}{5} + 4}

7 copies of the sum of 8 fifths and 4 mean that we have to multiply 7 with the sum of 8 fifths and 4.  The term of "the product" is synonymous with multiplication.

Let us write an expression to match for '7 copies of the sum of 8 fifths and 4'.

\boxed{\boxed{ \ 7 \times \bigg(\frac{8}{5} + 4 \bigg) \ }}

Let us calculate the operation in parentheses at first.

\boxed{ \ \frac{8}{5} + 4 \ }

\boxed{ \ \frac{8}{5} + \frac{20}{5} \ }

\boxed{ \ \frac{28}{5} \ }

And now we solve the full expression.

\boxed{ \ = 7 \times \bigg(\frac{8}{5} + 4 \bigg) \ }

\boxed{ \ = 7 \times \frac{28}{5} \ }

\boxed{\boxed{ \ \frac{196}{5} \ }}

In mixed fraction:

\boxed{ \ \frac{196}{5} = \ ? \ }

\boxed{ \ = \frac{195}{5} + \frac{1}{5} \ }

\boxed{ \ = 39 + \frac{1}{5} \ }

\boxed{\boxed{ \ 39\frac{1}{5} \ }}

In decimal:

\boxed{ \ 39\frac{1}{5} = \ ? \ }

\boxed{ \ = 39\frac{1 \times 2}{5 \times 2} \ }  

\boxed{ \ = 39\frac{2}{10} \ }  

\boxed{\boxed{ \ 39.2 \ }}

Thus, the result is \boxed{\boxed{ \ 39\frac{1}{5} \ or \ 39.2 \ }}.

Given: 
Square pyramid with lateral faces.
646 ft wide at the base.
350 ft high.

Because of the term lateral faces, we need to get the lateral area of the square pyramid.

Lateral Area = a √a² + 4 h² ; a = 646 ft ; h = 350 ft

L.A. = 646 ft √(646ft)² + 4 (350ft)²
L.A. = 646 ft √417,316 ft² + 4 (122,500 ft²)
L.A. = 646 ft √417,316 ft² + 490,000 ft²
L.A. = 646 ft √907,316 ft²
L.A. = 646 ft * 952.53 ft
L.A. = 615,334.38 ft²

Find the volume and explain please ASAP.
olya-2409 [2.1K]

Answer:

1395in^3

Step-by-step explanation:

First find the volume of the cuboid, 15in x 9in x 7in = 945in^3

Then find the volume of the rectangular pyramid using the formula V=lwh/3, the total height is 17in so subtract the height of the cuboid from the total height, giving you 10in.

V=(15in)(9in)(10in)/3 = 450in^3

450in^3 + 945in^3 = 1395in^3
