prohojiy [21]

Answer:

The length of each side of the polyhedron, s is 4.142 or

= 10(\sqrt{2}-1)

Step-by-step explanation:

If we take the distance of the length of the side of the cube where Donatello make the cut to the corner of the cube as x we get the side of length each polyhedron as

\sqrt{x^2 + x^2} = \sqrt{2x^2} =x\sqrt{2}

x·√2 because we have an hy

Therefore, the original cube had sides of length

10 = 2·x + x·√2

Solving for x we get

x = \frac{10}{\sqrt{2}+2 }

Therefore the length of s is x·√2 which gives

s = x\sqrt{2}  = \frac{10}{\sqrt{2}+2 }\sqrt{2} = 10\sqrt{2} -10 = 10(\sqrt{2}-1) = 4.142

The length of each side of the polyhedron, s = 4.142.

Julio places gray chairs and blue chairs in each row the ratio of gray to blue chairs in each row 7-3 how many gray chairs and b
g100num [7]

Answer:

56 gray chairs

24 blue chairs

Step-by-step explanation:

ratio of gray to blue chairs in each row

Gray : blue = 7 : 3

Gray chairs = 7

Blue chairs = 3

Total ratio = 7 + 3

= 10

how many gray chairs and blue chairs will julio use if he sets up a total of 80 chairs

Number of gray chairs = 7/10 × 80

= 0.07 × 80

= 56 gray chairs

Number of blue chairs = 3/10 × 80

= 0.03 × 80

= 24 blue chairs

56 gray chairs

24 blue chairs

Complete the steps to evaluate log798, given log72 ≈ 0.356. how can you rewrite log798 using the product property?
Valentin [98]

The expression  \rm log_{7} 98  using the product property is \rm log_{7} 49 + \rm log_{7} 2.

<h3>What is a logarithm?</h3>

A logarithm is the exponentiation inverse function that can be expressed by the exponent or power to which a base must be raised to yield a number.

It is given that \rm log_{7} 2 = 0.356

We can write \rm log_{7} 98 in terms of  \rm log_{7} 2

\rm log_{7} 98 = \rm log_{7} (49\times 2)

In logarithm, the product will change in addition

\rm log_{7} 98 = \rm log_{7} (49\times 2)

= \rm log_{7} 49 + \rm log_{7} 2

Hence, the expression  \rm log_{7} 98  using the product property is \rm log_{7} 49 + \rm log_{7} 2
