1 answer:
Alekssandra [29.7K]2 years ago
4 0

Answer:

84cm^2

Step-By-Step Explanation:

Two triangles' area: 4×3÷2x2 = 12cm^2

The widest rectangle's area: 5×6 = 30cm^2

The rectangle facing the left's area: 4×6 = 24cm^2

The rectangle facing the ground's area: 3×6 = 18cm^2

Total Surface Area: 12+30+24+18 = 84cm^2

A rectangle has a width of 8 centimeters and an area of 160 square centimeters a similar rectangle has an area of 250 square cen
Bezzdna [24]
I'm a bit confused and there is not a lot of information given to this.

From what I know, the dimensions of the larger rectangle can be found from length x width = 250 square centimetres.

Any multiplication problem that equals 250 could work out for length x width.

12. Building codes regulate the steepness of stairs. Homes must have steps that are at least 13 inches wide for each 8 inches
AfilCa [17]

Answer:

Slope tells you about the steepness of a line. It can is the ration of vertical change to horizontal change and you can solve this by using the slope formula:

a. So in your case, starting from the bottom, the slope is:

If you want to use coordinates, you can think of the first point (bottom of the stairs} would be at the point of origin (0,0). The next point would be at the top of the first stair 13 inches wide (horizontal or x) and 8 inches high (vertical or y)

So the coordinates of the two points would be:

(0,0) and (13, 8)

Using the formula we would have:

b. Looking at the answer above, you can see that the slope with increase if the vertical change is greater, so if you increase the height of the stairs, the stair would be steeper. The opposite is true if you would increase the width.

However, if you proportionally increase the width and the height, then the slope will remain the same.
