10 ≥ 2(2.99) + 0.67b
10 ≥ 5.98 + 0.67b
4.02 ≥ 0.67b
6 ≥ b

The kelvin scale is the standard absolute thermodynamic temperature scale.
Therefore, this question is simply asking you to convert the degree fahrenheit into degree kelvin.
The formula used to convert between kelvin and fahrenheit is as follows:
T(K)<span> = (</span>T(°F)<span> + 459.67) × 5/9
</span>
We will substitute in this equation with T(F)=-13 and calculate T(K) as follows:
t(K) = (-13 + 459.67) x 5/9 = 248.15 K
Based on this, the previous sentence can be written using absolute value of the number as follows:
The temperature at night reached 248.15 K.
If the value of a is positive, the line slopes upwards.
This is the concept of trigonometry, to solve for the value of the other length will be given cosine rule;
c^2=a^2+b^2-2ab cos C
substituting the values in our formula we get:
c^2=12^2+18^2-2*12*18*cos 60
c^2=144+324-432 cos60
c^2=252
hence
c=sqrt252
c=15.88m
thus the fixed length will be 15.88 m
Kimmy’s balance in December will be $486.98.
Explanation:
76.23 x 5 = 381.15
The balance is $381.15 in September.
381.15 + 87.83 = 468.98
The balance In December is $486.98.
