D. The true inequality is 7 < 12 < 16 < 25.
<h3>What is inequality?</h3>
Inequality is a statement of an order relationship including;
- greater than,
- greater than and equal to,
- less than, or
- less than and equal to
expressed between two numbers or algebraic expressions.
From the given options;
A. 3 > 4 < 5 < 9, this is not true since 3 is not greater than 4.
B. 17 < 20 < 4 < 5, this is not true since 20 is not less than 4.
C. 5 < 6 < 11 > 14, this is not true since, 11 is not greater than 14
D. 7 < 12 < 16 < 25, this is true, because 7 is less than 12 which is less than 16 and also less than 25
Thus, the option that contains the true statement of the inequalities is D.

The complete question is below:
A. 3 > 4 < 5 < 9,
B. 17 < 20 < 4 < 5,
C. 5 < 6 < 11 > 14,
D. 7 < 12 < 16 < 25
Answer:
45 and 47
Step-by-step explanation:
Answer:
1. 50 is 20% of 250
Step-by-step explanation:
In order to find any of these, use the equation.
Number/Out of = %
Then plug in the values
50/x = .20
Then solve by cross multiplying
50 = .20x
250 = x
Quick note: Since Riona wants to sell like 90 or 100 the answer I got was for 95.
I hope this helps you but the answer would be approximately about 83125.
Newton's Law of Cooling
Tf=Ts+(Ti-Ts)e^(-kt) where Tf is temp at time t, Ts is temp of surroundings, Ti is temp of object/fluid. So we need to find k first.
200=68+(210-68)e^(-10k)
132=142e^(-10k)
132/142=e^(-10k)
ln(132/142)=-10k
k=-ln(132/142)/10
k≈0.0073 so
T(t)=68+142e^(-0.0073t) so how long until it reaches 180°?
180=68+142e^(-0.0073t)
112=142e^(-0.0073t)
112/142=e^(-0.0073t)
ln(112/142)=-0.0073t
t= -ln(112/142)/(0.0073)
t≈32.51 minutes
