Answer:
a right triangle
is equal to
Step-by-step explanation:
Pythagorean's theorem is a²+b²=c² with c being the longest sides. If it is true then it is a right triangle.
<u>18²</u> + <u>24²</u> = <u>30²</u>
324+576=900
This is true so the triangle is a right triangle
I don't understand cuz it only goes to 10
8.2 grams = 1 mol
Na ________
22.99 grams
First multiply the value of 8.2 to 1. Then divide by the value of 22.99 to determine the number of moles of sodium present in the 8.2 gram sample.
Then use the following equation to solve for sodium atoms.
Number of moles of Na • Avogadro Number = Number of sodium atoms.
0.3566782 • (6.02 X 10^23). = 2.1472 X 10 ^ 23. Or 2.15 X 10 ^ 23.
The answer is the second option - 2.15 X 10 ^ 23.
Answer:
-55
Step-by-step explanation:
2nd term=> -1 + -2 × (2 - 1)
3rd term=> -1 + -2 × (3 - 1)
:
28th term=> -1 + -2 × (28 - 1)
=> -1 - 54 = -55
Divide by -2 for all of the numbers
64/-32=-2
-32/ 2= -16
-16/2= -8
-8/-2= 4
4/-2= -2
Answer : 4 ,-2
