Mathematics
1 answer:
BabaBlast [244]2 years ago
7 0

Answer:

Step-by-step explanation:

Yes!

The condition needed to get a proportional answer is the y intercept must be 0. No other value can be added on. It doesn't matter that the constant of proportionality is not an integer. x and y will always differ by 10.2 as a multiplied value

Put another way, the fraction y/x will always give 10.2

Considering it's dimensions and the formula, the volume of the cuboid is of 160 cm³.

<h3>What is the volume of a rectangular prism?</h3>

The volume of a rectangular prism, such as a cuboid, is given by the <u>area of the base multiplied by the height</u>, that is:

V = Ab x h

In this problem, the base is a square of sides 4 cm, with the height of 10 cm, hence the volume is given by:

V = 4² x 10 = 160 cm³.

Find the angle of depression
stich3 [128]

Answer:

Step-by-step explanation:

From B on the ground straight up to A and then turn the corner to follow the dotted line...that is a 90 degree angle. So in order to find the angle of depression, subtract 66 from 90 to get 24 degrees. Subsequently, that is also the angle of elevation (the base angle inside the triangle) due to parallel lines and whatnot.

A kitchen is 12 ft. by 14 ft. with 10 ft. high walls. How much would it cost to put vinyl flooring in this room? $8.80 per ft
Feliz [49]

<em>Answer:</em>

<em>In my opinion the answer would be 520x.</em>

<em>Step-by-step explanation:</em>

<em>Let x be the price of wallpaper per square feet. </em>

<em>Dimensions of a kitchen are: </em>

<em>width: w = 12 ft </em>

<em>length: l = 14 ft </em>

<em>height: h = 10 ft </em>

<em> </em>

<em>If you need to put wallpaper in the room, you will put it only on the walls. There are 4 walls in the kitchen: two walls which dimensions are 12 ft and 10 ft, and two walls which dimensions are 14 ft and 10 ft. Since walls are of rectangular shape, we will use the following formula for the area of walls: </em>

<em>A = 2 * w * h + 2 * l * h </em>

<em>A = 2 * 12 * 10 + 2 * 14 * 10 </em>

<em>A = 240 + 280 </em>

<em>A = 520 ft² </em>

<em> </em>

<em>So, if 1 square foot costs x, 520 square feet will cost </em><em><u>520x</u></em>
