The nth number is 81 /10.
Steps:
You multiple the denominator by itself
Answer:
X is an acute angle, which means it is less than 90*, so it is probably 45*
Step-by-step explanation:
I was confused at first but then, I’m just like, I can solve this!
It is definitely a. 9>5n
Because it say 9 is more than five times a number and if you have any questions just comment an I'll try to help! :) Hope I helped!
Answer:
1.6x10^-18 gram
Step-by-step explanation:
(5.3 x 10⁻²³ gram/molecule) x (20,000 molecule)
= (5.3 x 10⁻²³ x 2 x 10⁴) gram
= (10.6 x 10⁻²³⁺⁴) gram
= (1.06 x 10⁻²³⁺⁵) gram
= 1.06 x 10⁻¹⁸ gram
We need to find the mass of 20,000 molecules of oxygen. It can be calculated using unitary method. Here, we can multiply 20,000 molecules by the mass of one oxygen molecule.
Here, 3t - 7 = 5t
5t - 3t = -7
2t = -7
t = -7/2
Then, 6t = 6(-7/2) = 3(-7) = -21
In short, Your Answer would be -21
Hope this helps!
