Answer:

Step-by-step explanation:
If we draw a right triangle, it would have legs 6 and 2.
Answer:
9 inches.
Step-by-step explanation:
The formula for the volume of a rectangular prism is base x height. So if the volume is 378, and the base is 42, you would use the equation 378/42 to find the height. 378/42 is 9. Therefore, the height is 9 inches.
Answer:
See below in bold.
Step-by-step explanation:
It looks like the third term should be -36.
The sequence is geometric.
The common ratio is -54/-81 = -36/-54 = -24/-36 = 2/3 .
The sum of the first 5 terms is
(-81) * (1 - (2/3)^5) / (1 - 2/3)
= -81 * 211/243 * 3
= -211.
20^2-12^2=x^2
400-144=x^2
256=x^2
x=16
<em>h ≈ 0.25 cm</em>
- <em>Step-by-step explanation:</em>
<em>Hi there !</em>
- <u><em>density formula</em></u>
<em>d = m/V</em>
<em>V = l×w×h</em>
<em>replace</em>
<em>2.17 = 438/(40×20)×h</em>
<em>2.17 = 438/800×h</em>
<em>2.17×800×h = 438</em>
<em>1736h = 438</em>
<em>h = 438/1736</em>
<em>h ≈ 0,25 cm</em>
<em>Good luck !</em>
