3 0

Answer:

a. x = 9

b. x = 3.6

Step-by-step explanation:

a. By Basic proportionality theorem:

AB/BD = AC/CE

4/4 = x/9

1 = x/9

9 = x

x = 9

b.

In \: \triangle ABC \: \& \: \triangle EDF\\\angle B \cong \angle D....(given) \\\angle C \cong \angle F.....(given) \\\therefore \triangle ABC \: \sim \: \triangle EDF.. (AA\: POSTULATE) \\\therefore \frac{AB}{ED} = \frac{BC}{DF} ...(csst) \\\therefore \frac{2}{5} = \frac{x}{9}\\\therefore x = \frac{2\times 9}{5} \\\therefore x = \frac{18}{5} \\\huge \red{\boxed {\therefore x = 3.6}} \\

A rectangular prism of volume 3200 mm has a rectangular base of 10 mm and width 8 mm. Find the height h of the prism
Orlov [11]

Answer:

40 mm

Step-by-step explanation:

The rectangular prism of a rectangular box. The volume is given by the formula:

<u>Volume of Rectangular Prism</u> = length * width * height

Given Volume = 3200

Length = 10

Width = 8

We need to find height. So we plug in the given information and find the height, in mm. Shown below:

Volume = Length * Width * Height

3200 = 10 * 8 * Height

3200 = 80 * Height

Height = 3200/80

Height = 40 mm

The height (h) = 40 mm
