the square is the only quadrilateral that has only all the same sides with the equal lengths and angles
In the expression <span>2a x 3b x 4c,
2, 3 and 4 are the coefficients and a, b and c are the variables.
When such a multiplications is given, multiply the coefficients together and the variables together.
So the product of coefficients = 2</span>×3×4 = 24
the product of variables = a×b×c = abc
Finally multiply the product of coefficients and product of variables.
Final product = 24×abc = 24abc
So <u>24abc</u> is the answer.
Answer:
6 and 2/5
Step-by-step explanation:
6 2/5 ÷ 1/1 keep cange flip
32/5× 1/1
32/5
32÷5
=6/25
This question is the application of differential eqns in order to derive a model for the temperature dependence with time. Actually, a general equation has already been derived for this type of cases. This equation is known as the Newton's Law of Cooling. The equation is
(T - Ts) / (To -Ts) = e^(-kt)
where T is the the temperature at any time t
Ts is the surrounding temperature
To is the initial temperature
k is the constant
t is the time
several assumptions have been made to arrive at this form, i suggest you trace the derivation of the general formula.
First we need to look for k using the initial conditions that is @t = 1.5 min, T = 50 F
substituting we get a k = 0.2703
therefore @ t = 1 min, T = 55.79 F
@ T = 15 F the time required is 9.193 min.
