Answer:
The combined amount is $14871.21.
Step-by-step explanation:
It is given that, the total yearly income of gentry family is <em>$29742.42</em>
<em>The % charge on income for food is 20%.</em>
<em>The % charge on income for housing is 30%.</em>
The amount in dollar from % form is given by,
= 
For annual food,
= 
= $5948.484
For housing budgets,
= 
= $8922.726
Thus the combined amount is,

= $14871.21
Answer:
The height of the big cone is double the one in the small cone
h2 = 2h1
Step-by-step explanation:
Given that:
- The volume of the small cone: 5 cubic inches
- The volume of the big cone: 10 cubic inches
As we know, the volume of a cone is as following:
V = (1/3)*area of the base*height
If the base diameter are unchanged => area of the base of the two cones are unchanged and from the given information, the volume of the big cone is double the volume of the small cone. So the height of the big cone is double the one in the small cone
<=> h2 = 2h1
The answer is f(x)=x²+2x when evaluated with -3 gives you the value of 3
