Remark
Assume all of the sheet of plywood is to be used.
Front and back = 2 * 2x *h
Top and Bottom = 2 * 2x * x
Left/Right side = 2 * x * h
Total area = 4xh + 4x^2 + 2xh
Total area = 6xh + 4x^2
Total area = 600
6xh + 4x^2 = 600
h = (600 - 4x^2)/6x
h = 100/x - 2/3 x
Volume = x * 2x * h
Volume = 2x^2 * (100/x - 2/3 x)
Volume = 200x - 4/3 x^3
I can do this without calculus (I think), but it is much easier to use it.
dV/dx = 200 - 4x^2
This is a maximum when dV/dx = 0
dV/dx = 200 - 4x^2 = 0
4x^2 = 200
x^2 = 50
x = 5√2
The measure of A is 14 degrees greater than the measure of B. The two angles are complementary. Find the measure of each angle
Answer:
[tex]A = 52[/tex], [tex]B = 38[/tex]
Step-by-step explanation:
The sum of two complementary angles is always [tex]90[/tex]°
[tex]A + B = 90[/tex]
[tex]A = B + 14[/tex]
substitute [tex]A[/tex] for [tex]B = 14[/tex]
[tex](B + 14)+ B = 90[/tex]
[tex]2B + 14 = 90[/tex]
[tex]2B = 76[/tex]
[tex]B = 38[/tex]
input this into the original equation
[tex]A + 38 = 90[/tex]
[tex]A = 52[/tex]

Find the area of the figure.
Answer:
33 sq units
Step-by-step explanation:
if you section it off into a rectangle and two triangles, the large rectangle that makes up most of the shape is 6x4 units or 24 sq units. each triangle is 3x3 units, so together they would make one 3x3 square. the 3x3 square would have an area of 9, and the answer is 24+9, or 33 sq units

What is 45 minutes before 7 o'clock
Answer: Its 6:15
Step-by-step explanation:
Its simple math. 7:00 subtract 45minutes, knowing that 60minutes is an hour and that its the 7 hour from the 6 hour. Gets you 6:15.
Yep.
The 45 minutes before 7 o'clock will be 6.15 AM/PM.
What is the time?the indefinite continued progress of existence and events in the past, present, and future regarded as a whole.
In other words, time is something which measure by motion and it is given by einstein that time depends upon motion.
For example time = distance/velocity so it means time also depends on velocity.
In the given question, we know that in
1 hour = 60 minutes
45 minutes before of 7 o'clock = 60 - 45 = 15 minutes after 6 o'clock hence 6.15 minutes will be correct answer.

Select whether each equation is a linear equation in standard form. Select Yes or No for each equation.
Answer:
yes
Step-by-step explanation:
Move 4x to the right to get y= -4x + 5. This is a linear equation because the graph of it is a straight line.
Write the equation of this line in y= mx + b form
Answer:
y=2x
Step-by-step explanation:
Slope (m): the formula for slope is y2-y1 over x2-x1 so it will be 2-(-2) over 1-(-1) and the result will be 2.
Y intercept: The Y intercept is 0 as shown in the graph

receives a shipment weighing 2y pounds. Which expression represents the weight of the
has?
Highlight
X-15-2y
O X+ 15 + 2y
O
x + 15 - 26
O
X - 15 + 2y
Answer: x - 15 + 2y
Step-by-step explanation:
A Starbucks manager has x pounds of coffee in stock and then sells 15 pounds. The amount of pounds of coffee left will be:
= x - 15
He then receives a shipment weighing 2y pounds. This means that the weight of the coffee he has will then be:
= x - 15 + 2y

Answer:
8) interior angle = 160
9) x = 20
Step-by-step explanation:
8)
18-gon has 18 sides
The formula for sum of interior angles for an 18-gon is:
(18x180)-360 = 2880 degrees
2880 degrees / 18 angles = 160 degrees
9)
exterior angles = 360 degrees
360 = (3x-2)+(x+8)+(4x+9)+(2x-1)+(3x)+(4x+6)
360 = 3x-2+x+8+4x+9+2x-1+3x+4x+6
360 = 17x+20
17x = 340
x = 20 degrees

Write the rule of the transformation
Answer:
(x + 5, y + 1)
Step-by-step explanation:
As we can see, what we have is a translation
let us pick a point
G( -5,-2)
To;
G’(0,-1)
so the shift on the x-axis is;
(0-(-5)) = 5
shift on the y-axis is;
(-1-(-2) = 1
we have a rightward shift of 5 units on the x-axis and 1 unit on the y-axis
So we have the rule as;
(x + 5, y + 1)

The area of this trapezoid is what?
Answer:
The area of this trapezoid is 8cm
Answer:
130
Step-by-step explanation:
first decompose the trapezoid into a square in the middle and 2 triangles on the left/right side, both triangles are congruent so you only find the area of one triangle, which is 9 because do 2x9 = 18/2 = 9, now let's move on to the middle square 14 x 18 = 112, then you add them all up remember there are 2 triangles,
112 + 9 + 9 = 130
