The amount paid for the computer including sales tax is 0.918p

<h3>How to determine the amount paid?</h3>

The price paid is given as:

Price = p

A 15% off means that he pays 85%.

So, we have:

Amount = 85% * p = 0.85p

A sales tax of 8% means:

Total = 0.85p * (1 + 8%)

Evaluate the product

Total = 0.918p

Hence, the amount paid is 0.918p

Mai wants to make a scale drawing of her kitchen. Her kitchen is a rectangle with length 6 m and width 2 m. She decides on a sca
BigorU [14]

Answer:

Length of scale = 15 cm

Width of scale = 5 cm

Step-by-step explanation:

Dimensions of the kitchen of Mai are given as:

Length of kitchen = 6 m

Width of kitchen = 2 m

Scale to be used = 1 to 40

To find:

The drawing with labeling and dimensions of the scale drawing.

Solution:

First of all, let us understand about the concept of scaling.

Scaling is a method to represent big structures on paper.

For this purpose, we decide a scaling factor and draw the big structures on paper by scaling down (making it small) by using a scaling factor.

Here, the scale factor used is 1 to 40.

i.e. 1 unit on scale is equivalent to 40 units on the actual kitchen.

40 units of kitchen = 1 unit of scale

1 unit of kitchen = \frac{1}{40} units of scale

6 m of kitchen = \frac{1}{40}\times 6\ m = \frac{600}{40}\ cm = 15\ cm

Length of scale = <em>15 cm</em>

40 units of kitchen = 1 unit of scale

1 unit of kitchen = \frac{1}{40} units of scale

2 m of kitchen = \frac{1}{40}\times 2\ m = \frac{200}{40}\ cm = 5\ cm

Width of scale = <em>5 cm</em>

<em></em>

Please refer to the attached image as well for representation of given scale.

Find the base of the triangle whose area is 2.4 cm² and who is height is 1.6 cm
Karo-lina-s [1.5K]

Formula of the area of triangle: (BxH)/2

So:

1.6B/2 = 2.4

Multiply both sides by 2:

1.6B = 4.8

Divide both sides by 1.6:

B = 3

a wooden box has external dimensions 40 cm by 34 cm by 30 cm. if the wood is 1 cm thick how many cm3 of wood is used in it ?​
Westkost [7]

Answer:

6752 cm³ of wood

Step-by-step explanation:

V = 40cm×34cm×30cm = 40800 cm³

v = 38cm×32cm×28cm = 34048 cm³

V - v = 40800cm³ - 34048cm³ = 6752 cm³ of wood
