Well, first they're assuming that the m<ABC = 90

The value of m<ABC is not given, so they aren't allowed to make up values based on the way the picture looks.

It is given that BD bisects <ABC, which means it splits the angle evenly..

Giving this equation: (x-5) = (2x-6)

Solving for x

-5 + 6 = 2x - x

1 = x

Bond [772]

Answer:

b. is $34 per ounce

Step-by-step explanation:

If the production cost were less, a competitor would drive the price down. If the production cost were more, the supplier would go out of business.

Since we're at equilibrium, the production cost must be equal to $34 per ounce.

A plan of a garden is shown below.

siniylev [52]

The length and width of the conservatory are both 4.5 meters

<h3>How to determine the length and the width?</h3>

From the figure, we have the following highlights:

Length = 3 units
Width = 3 units

A unit = 1.5 meters

So, we have:

Width = Length = 3 * 1.5 meters

Width = Length = 4.5 meters

Hence, the length and width of the conservatory are both 4.5 meters

What is the volume of the sphere that has a diameter of 3? use 3.14 for pie

aev [14]

Hey ! there

Answer:

113.04 unit cube

Step-by-step explanation:

In this question we are provided with a sphere having radius 3 units and value of π is 3.14 . And we're asked to find the volume of sphere .

For finding volume of sphere , we need to know its formula . So ,

$\qquad \qquad \: \underline{\boxed{ \frak{Volume_{(Sphere)} = \dfrac{4}{3} \pi r {}^{3} }}}$

Where ,

π refers to 3.14

r refers to radius of sphere

Solution : -

Now , we are substituting value of π and radius in the formula ,

$\quad \longrightarrow \qquad \: \dfrac{4}{3} \times 3.14 \times (3) {}^{3}$

Simplifying it ,

$\quad \longrightarrow \qquad \: \dfrac{4}{3} \times 3.14 \times 3 \times 3 \times 3$

Cancelling 3 with 3 :

$\quad \longrightarrow \qquad \: \dfrac{4}{ \cancel{3}} \times 3.14 \times 3 \times 3 \times \cancel{3}$

We get ,

$\quad \longrightarrow \qquad \:4 \times 3.14 \times 9$

Multiplying 4 and 3.14 :

$\quad \longrightarrow \qquad \:12.56 \times 9$

Multiplying 12.56 and 9 :

$\quad \longrightarrow \qquad \: \pink{\underline{\boxed{\frak{113.04 \: unit \: cube}}}} \quad \bigstar$

Henceforth , volume of sphere having radius 3 units is 113 .04 units cube .
