Let, the time when <span>Jan cough up to Carol = x
We know, Distance = Speed * Time.
So, Equation would be: 2x + 5*2 = 6x
2x + 10 = 6x
6x - 2x = 10
4x = 10
x = 10/4 = 2.5
Distance traveled in that time = 2.5 * 6 = 15 miles
In short, Your Answer would be: 15 miles
Hope this helps!</span>
The approximate total mass= number of atoms * weight of an atom.
The approximate total mass=3.06 10²³ atoms. (1.67 10⁻²⁴ grams/1 atom)=
=0.51102 g ≈ 0.51 g
Answer: the spproximate total mass is 0.51 grams.
Step-by-step explanation:
Given sequence is: - 3, 5, 13...
Here first term a = - 3
common difference d= 5-(-3)=13-5=8
Hence, it is in A. P.

Which is the required formula for the given sequence.
Answer:
A. 23/30
Step-by-step explanation:
2/3+1/10
Find the LCM (Least Common Multiple):
20/30+3/30 = 23/30
Answer: D
Step-by-step explanation:
Formula= 2piRh +2piR^2
2pi*7*11 + 2pi*49 = 791.68 or 792
