Answer:
20
Step-by-step explanation:
<u>25 </u> = <u> x</u>
20 16
(25*16)/20 = 20
3 bottles
area=base x height
area=30 x 15=450 ft^2
450/180=2.5
Neither of the options are correct for the given equations.
-x+y=4...................................................1
16x+y=-3...............................................2
Subtract equation 1 and 2
-x+y- 16x -y = 4+3
⇒ -17x = 7
⇒x=
⇒x= -0.4117
so,
16×-0.4417 + y = -3
⇒y= -3+6.5872
⇒y= 3.5872
So the point of intersection is (-0.4117, 3.5872)
1a. {2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13}
1b. {5}
For part 1:
A U B is the union of all values, so {2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13}
Remember that union means to include all values.
A n B is the intersection of all values, so {5}
Remember that the intersection means "what do they have in common".
