<h3>Simplifying an Expression </h3>

From the question, we are to write the given expression in its lowest terms

The given expression is

ab/b2

That is,

\frac{ab}{b^{2} }

This can be expressed as

\frac{a \times b}{b \times b}

=\frac{a}{b}

Hence, the given expression written in lowest terms is a/b

A circle has a central angle measuring startfraction 7 pi over 6 endfraction radians that intersects an arc of length 18 cm. wha
mash [69]

The radius of this circle is (B) 4.9 cm.

<h3>To find the radius of the circle:</h3>

To solve this problem, we need to, first of all, convert the angle from radians to degrees.

data;

  • length of an arc = 18cm
  • angle = 7/6π rads
  • π= 3.14

\frac{7\pi }{6rads} =210^{0}

Length of an Arc:

The formula for the length of an arc is given:

l_{arc} = θ/360 × 2\pi r

Let's substitute the values and solve:

18=\frac{210}{360} *2\pi r\\18=3.663r\\r=\frac{18}{3.663} \\r=4.9cm

From the calculations above, the radius of this circle is 4.9cm.

Therefore, the radius of this circle is (B) 4.9 cm.

To the nearest square meter, what is the curved surface area of the half pipe if it’s 7 m long?
cupoosta [38]

Answer:

  55 m²

Step-by-step explanation:

The arc length of a half-circle is πr, so the area of the curved surface is ...

  A = πrl = π(2.5 m)(7 m) = 17.5π m² ≈ 55 m²

How do you solve this? [question in attachment]

\large\blue\textsf{\textbf{\underline{\underline{Answer and How to Solve:-}}}}

In order to find the perimeter of a shape, we should add all of its sides.

Since a triangle has only 3 sides, we add 3 sides together, like so:-

      ⇒ 9x-7+12x-13+3x+8

Combine like terms:-

    ➪ 9x+12x+3x-7-13-8

Which simplifies to

     ➪9x+15x-7-21

On further simplification,

➪24x-28

So we conclude that the perimeter of the triangle is 24x-28 units.

<h3 /><h3>Good luck.</h3>
