7 copies of the sum of 8 fifths and 4

Answers

Answer 1

Answer:

Answer:

39.2

Step-by-step explanation:

We need to find the solution of 7 copies of sum of 8 fifths and 4.

Now, 8 fifths = $(8)/(5)$

Then, sum of 8 fifths and 4 = $(8)/(5)+4$ = $(28)/(5)$

Now, 7 copies of $(28)/(5)$ means that we meed to multiply $(28)/(5)$ 7 times

i.e. 7 copies = $7* (28)/(5)$

i.e. 7 copies = $(196)/(5)$

i.e. 7 copies = 39.2

Hence, 7 copies of sum of 8 fifths and 4 is 39.2

Answer 2

Answer:

39¹/₅ or 39.2

Further explanation

The Problem:

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

The Process:

Here are some early expressions that need attention.

8 fifths is $\boxed{(8)/(5)}$
the sum of 8 fifths and 4 is $\boxed{(8)/(5) + 4}$

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'.

$\boxed{\boxed{ \ 7 * \bigg((8)/(5) + 4 \bigg) \ }}$

Let us calculate the operation in parentheses at first.

$\boxed{ \ (8)/(5) + 4 \ }$

$\boxed{ \ (8)/(5) + (20)/(5) \ }$

$\boxed{ \ (28)/(5) \ }$

And now we solve the full expression.

$\boxed{ \ = 7 * \bigg((8)/(5) + 4 \bigg) \ }$

$\boxed{ \ = 7 * (28)/(5) \ }$

$\boxed{\boxed{ \ (196)/(5) \ }}$

In mixed fraction:

$\boxed{ \ (196)/(5) = \ ? \ }$

$\boxed{ \ = (195)/(5) + (1)/(5) \ }$

$\boxed{ \ = 39 + (1)/(5) \ }$

$\boxed{\boxed{ \ 39(1)/(5) \ }}$

In decimal:

$\boxed{ \ 39(1)/(5) = \ ? \ }$

$\boxed{ \ = 39(1 * 2)/(5 * 2) \ }$

$\boxed{ \ = 39(2)/(10) \ }$

$\boxed{\boxed{ \ 39.2 \ }}$

Thus, the result is $\boxed{\boxed{ \ 39(1)/(5) \ or \ 39.2 \ }}$ .

Answers

She's going to need about 30.

Estimate 34.
567 divide 18 =31.5
therefore she needs 32 shelves to stock all the earmuffs.

A cone-shaped container sits inside a larger cone. The inner cone has a height of 3 in. and a diameter of 6 in. The outer cone has the same diameter and is 15 in. tall. The extra space in the outer cone is filled with crushed ice to keep the contents of the inner cone cool.

Answers

What is the volume of the crushed ice?

volume of the cone = π r² h/3

volume of the small cone = 3.14 * (3in)² * 3in/3
volume of the small cone = 3.14 * 9in² * 1in
volume of the small cone = 28.26 in³

volume of the big cone = 3.14 * (3in)² * 15in/3
volume of the big cone = 3.14 * 9in² * 5in
volume of the big cone = 141.30 in³

volume of the crushed ice = 141.30 in³ - 28.26 in³ = 113.04 in³
