we are given with a triangle with the sides 6 ft, 21 ft, 23 ft. although it follows the rule of triangles that state that no side of the triangle exceeds the sum of the lengths of two other sides, this does not follow Pythagorean theorem: 23^2-21^2 = 88 which is not equal to 6^2 or 36. This is not a right triangle, hence. Hope this helps!

How to change a precent to a decimals

andrew11 [14]

To change a percent to a decimal, you must move the decimal point inwards two places. For example, say you have 45%. To change 45% to a decimal, move the decimal point in two places, and you will have 0.45. Once you’ve moved the decimal, don’t add the percent symbol, because it’s no longer a percent.

Please help I really need your help

Amanda [17]

Answer:

1. $1200 \ kg/m^3$

35 cm = 0.35 meters

11 dm = 1.1 meters

15 mm = 0.015 meters

Volume = 0.005775 cubic meters

Mass = 15.5925 kilograms

Step-by-step explanation:

We know

Density = Mass/Volume

Given

Mass = 90 kg

Volume = 0.075 cubic meters

The SI unit for density is kilograms per cubic meters. Our dimensions are just that, so we just need to plug in the numbers into the formula and get our answer. Shown below:

Density = $\frac{90}{0.075}=1200 \ kg/m^3$

The Density of asphalt block = $1200 \ kg/m^3$

We need to express 35cm, 11dm, and 15mm in meters

We know

100 cm = 1 meters, so

35 cm = 35/100 = 0.35 meters

We know 1 dm = 0.1 meters, so

11 dm * 0.1 = 1.1 meters

We know, 1mm = 0.001 meters, so

15 mm * 0.001 = 0.015 meters

Volume of the Slab is length * width * height, in meters, that would be:

Volume = 0.35 * 1.1 * 0.015 = 0.005775 cubic meters

THe mass would be found by the formula:

Density = Mass/Volume

2700 = Mass/0.005775

Mass = 0.005775 * 2700 = 15.5925 kilograms
