10 x 2.45= 24.50. First you divide 19.60 by 8 and you get 2.45. Then you multiply 2.45 and 10.
Answer:
480
Step-by-step explanation:
30x12= 360
360+120=480
Answer:
V = 240 in ^3
SA = 2(lw+lh+wh)
SA = 236 in^2
Step-by-step explanation:
Volume = l*w*h where l=length, w= width and h =height
We know l=6, w=5 and h =8
V = 6*5*8
V = 240 in ^3
The formula for surface area of a rectangular prism is
SA = 2(lw+lh+wh) where l=length, w= width and h =height
We know l=6, w=5 and h =8
Substituting into the equation
SA = 2(6*5+6*8+5*8)
= 2 (30+48+40)
=2(118)
= 236 in ^2
Answer:
Yes.
The relation is a function because every element in the domain (the x's) is mapped to one element in the range (the y's).
Step-by-step explanation:
For a relation that is a set of points all you have to look for while igorning any duplicate points is that all of the x's are different. If there are any 2 (or more) x's that are the same, then it is not a function.
So there are no duplicate points.
For example the set {(1,5),(2,5)(1,5)} is really just {(1,5),(2,5)}.
Anyways the x's in the points are (in order from left to right):
1
-4
3
0
2
All of these are different, I did not list a value for x that was same anywhere in that list. So it is a function.
The relation is a function because there is no x that gets mapped to more than one y.
