The volume is equal to l*w*h, and we know that the base is 4 1/2 in^2, so divide 18/4 1/2, and you’ll get 4. The height of the juice box is 4 inches.
Let's see what's the domain and range for the given function ~
![\qquad \tt \dashrightarrow \:domain \in [ -5 , 4 ]](https://tex.z-dn.net/?f=%5Cqquad%20%5Ctt%20%5Cdashrightarrow%20%5C%3Adomain%20%5Cin%20%5B%20-5%20%2C%204%20%5D%20)
or
Because domain = all values of x between its maximum (4) and minimum (-5) value [ including them ]
![\qquad \tt \dashrightarrow \:range \in[ -4 , 9 ]](https://tex.z-dn.net/?f=%5Cqquad%20%5Ctt%20%5Cdashrightarrow%20%5C%3Arange%20%5Cin%5B%20-4%20%2C%209%20%5D)
or
Because range = all values of y between its maximum (9) and minimum (-4) value [ including them ]
If the speed of the stream is x
Time is given by d/r , where r is the rate and d is the distance;
Rate for upstream = (15-x) mph and that of down stream is (15 +x) mph
The time taken will be the same;
Thus; 2/(15-x) = 4/(15+x)
cross multiplying;
30 +2x = 60 -4x
6x = 30
x =5
Therefore the rate of the river is 5 mph
27 salads because if you out it in a proportion of 12/20=x/45 x= 27
the second question would be $7.40 because $29.60/4 is $7.40
Answer:
x=1
Step-by-step explanation
:−5x=−2x−3
Step 1: Add 2x to both sides.
−5x+2x=−2x−3+2x
−3x=−3
Step 2: Divide both sides by -3.
−3x
−3
=
−3
−3
x=1
