The volume of a rectangular prism is 400 cm3 . If the length is 16 cm and the width is 5cm, what is its height? ​
tester [92]

Answer:

H = 5

Step-by-step explanation:

rectangular prism:

V = L x W x H

400 cm3 = 16 x 5 x H

400 cm3 = 80 x H

400/80 = 5

h = 5 cm

95% sure this is correct! :)

Im thinking of 2 numbers. The sum of the 2 numbers is -22. The difference of the 2 numbers is 122.
Bas_tet [7]

Answer:

The numbers are 50 & -72.

Step-by-step explanation:

Let the first number is x and the second number is y.

According to the question:-

x + y = -22        ........(1)

x - y = 122         ........(2)

By adding equation 1 & 2-

2 x = 100

x = 50

Put X =50 in equation (1)-

y = -22 -50

y = -72

Hence the numbers are (50, -72).

PLEASE HELP ME IF YOU CAN ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Reil [10]

Answer:

The maximum is at (0,4)

Step-by-step explanation:

x≥0

y≥0

x+y ≤4

2x+y ≤6

We need to plot the four inequalities.  The left side has no axis.  The max is at 4.  The minimum is at 0  for the shaded area

When we have a system of constraints, the minimum and maximum are at the vertices of the graph

There are 4 points

(0,0)

The intersection point of the 2 lines which is (2,2)

The intersection at the y axis (0,4)

The intersection at the x axis is (3,0)

Once we have these points we put them into the constraint equation

C = 30x+50y

(0,0)

C = 0+0 = 0  This would be the trivial point since nothing happens

(0,4)

C = 0+50(4) = 200

(3,0)

C = 30*3 = 90

(2,2)

C = 30(2) + 50(2) = 60+100 = 160

The maximum is at (0,4)

Evaluate the following expression using the values given.
White raven [17]
Most of the information's required for solving this question is already given. It is important to put the values correctly and then solve to find the answer.

2x2 - 2z4 + y2 - x2 + z4 = 2(-4)^2 - 2(2)^4 + (3)^2 - (-4)^2 + (2)^4
                                       = (2 * 16) - (2 * 16) + 9 - 16 + 16
                                       = 32 - 32 + 9 -16 + 16
                                       = 9
I hope the answer has actually come to your desired help. I also hope that this is the answer that you were looking for and the answer has actually come to your desired help.
