DaniilM [7]3 years ago

Answer:

<h2>9<n<17.</h2>

Step-by-step explanation:

9 less than a number <em>n</em> is less than 17. This verbal expression can be represented as a mathematical expression.

First, we observe that it says "9 less than", this is expressed like 9<, but less than who? it says "less than <em>n"</em>, so it would be 9<n.

In second place, the expression continues, <em>n </em>is less than 17, which is expressed like n<17.

At last, we unite both parts, and we have:

9<n<17.

a regular hexagonal nut of side 1 cm and length 3 cm with a central hole of diameter 1 cm. 3 cm 1 cm 1 cm. Calculate the volume
Bogdan [553]

Answer:

  5.44 cm³

Step-by-step explanation:

The volume of the hexagonal nut can be found by multiplying the area of the end face by the length of the nut. The end face area is the difference between the area of the hexagon and the area of the hole.

The area of a hexagon with side length s is given by ...

  A = (3/2)√3·s²

For s=1 cm, the area is ...

  A = (3/2)√3(1 cm)² = (3/2)√3 cm²

__

The area of a circle is given by ...

  A = πr²

The radius of a circle with diameter 1 cm is 0.5 cm. Then the area of the hole is ...

  A = π(0.5 cm)² = 0.25π cm²

__

The volume is the face area multiplied by the length, so is ...

  V = Bh = ((3/2)√3 -0.25π)(3) . . . . . cm³

  V = (9/2)√3 -0.75π cm³ ≈ 5.44 cm³

The volume of the metal is about 5.44 cm³.

What is log3 ( x+5)=2?
Naddik [55]

(3) is the base of the new equation

(x + 5) is the answer of the new equation

(2) is the exponent on base (3)

;The new equation after simplifying is...,

; 3^2 = x + 5

; 9 = x + 5

; x = 9 - 5

;Hence...x = 4
