Answer:
180
Step-by-step explanation:
A possible solution of the system of inequalities is 5 dimes and, 8 nickels
<h3>How to determine a possible solution?</h3>
From the question, the given parameters are:
Number of coins = Not less than 12
Worth = At most $0.95
Represent dime with x and nickels with y
So, we have the following inequalities
x + y >= 12
0.1x +0.05y <= 0.95
Next, we plot the graph of the inequalities (see attachment)
From the graph, we have a possible solution to be (5, 8)
This is so because this point is in the shaded region

Answer:
1500
Step-by-step explanation:
The average rate of change of a function on the interval [a, b] is given by ...
rate of change = (f(b) -f(a))/(b -a)
On the interval [7, 9], the average rate of change is ...
(5760 -1920)/(9 -7) = 3840/2 = 1920
On the interval [4, 6], the average rate of change is ...
(945 -105)/(6 -4) = 840/2 = 420
The rate of change on the first interval is greater by ...
1920 -420 = 1500
According to picture Jennifer’s grandmother buys = 28 kg of carrots.
Total number of grandchildren = 3.
Number of kilograms of carrots are distributed equally.
<u>In order to find the Number of kilograms of carrots are distributed, we need to divide total Kgs of carrots by total number of grandchildrens.</u>
Therefore ,
28 ÷ 3 .
On dividing 28 by 3, we get 7.
Therefore, Jennifer will get 7 kilograms of carrots.
The answer would be 6.412 × 10^4
