The figure below represents a rectangular prism net. The rectangles labeled B represent both bases of the prism. What is the difference between the lateral and total surface area of the prism? (Hint: What are the only rectangles you are finding the area of?)
A : 156in
B : 128in
C : 30in
D: 48in
Answers
The total surface area and lateral area have a difference of 48 square inches. (Correct choice: D)
How to difference lateral area and total surface area in a right prism
In this problem we find a right prism with a rectangular base, of which we must determine its lateral area and its total surface area, both in cubic inches.
Lateral area is the sum of all faces A and C (four rectangles), whereas total surface is the sum of lateral area and all faces B (two rectangles). Area formula for rectangles is shown below:
A = w · l
Where:
w - Width, in inches.l - Length, in inches.A - Area, in square inches.Now we proceed to determine the lateral area and the total surface area of the prism:
Lateral area
A' = 2 · (3 in) · (5 in) + 2 · (8 in) · (5 in)
A' = 30 in² + 80 in²
A' = 110 in²
Total surface area
A = A' + 2 · (8 in) · (3 in)
A = 110 in² + 48 in²
A = 158 in²
And the difference between total surface area and lateral area is equal to 48 in².

By polynomial equation, 7i , −7i this we get 1, y = x² + 49 .
What is polynomial equation?The x-axis and the graph's intersection points, or the places where y = 0, are known as the roots.
The roots of y equal 0
By figuring out what x is when x ( 7 I ) = y and y = 0 we can find the root at x = 7 i.
x 7 I is the factor.
By determining the value of x at the point where x ( 7 I ) = y and y = 0, the root at x = 7 I was discovered.
x + 7 I is the factor.
One equation can be created by combining all the variables.
y = ( x − 7 i ) ( x + 7 i)
To make the equation y = (x 7 I (x + 7 I easier to understand, multiply all the elements.
Use the FOIL Method to extend (x 7 I ) (x + 7 I
Put the distributive property to use.
y = x ( x + 7 i ) − 7 i ( x + 7 i )
Put the distributive property to use.
y = x ⋅ x + x ( 7 i ) − 7 i ( x + 7 i )
Put the distributive property to use.
y = x ⋅ x + x ( 7 i ) − 7 i x − 7 i ( 7 i )

a rancher who wishes to fence off a rectangular area finds that the fencing in the east-west direction will require extra reinforcement due to strong prevailing winds. fencing in the east-west direction will therefore cost per (linear) yard, as opposed to a cost of per yard for fencing in the north-south direction. given that the rancher wants to spend on fencing, express the area of the rectangle as a function of its width .
Answers
The dimension of the largest possible rectangular area that can be fenced for $4800 is 300 yard × 150 yard. The area, A of the rectangle as a function of its width, w is A = 300w - 1.5w².
Let the width of the rectangular area be "w" and its length be "l".
The cost of the east-west direction fencing is
2w * 12 = 24w
and the cost of the north-south direction fencing is
2l * 8 = 16l
Since the rancher wants to spend exactly $4800 on fencing, we can write an equation to represent the cost:
24w + 16l = 4800
Divide by 8
3w + 2l = 600
Therefore, l = 300 - 1.5w
The area of the rectangle is given by "lw", so
A = lw
Substituting the value of "l" from the first equation into this second equation:
A = (300 - 1.5w)w
A = 300w - 1.5w²
Thus, the area of the rectangle is a function of its width and can be expressed as Area = 300w - 1.5w².
To find value of w with maximum area, dA/ dw = 0
300 - 3w = 0
w = 100
Therefore, l = 300 - 1.5*100
l = 150

two socks are drawn from a drawer which contains one red sock, three blue socks, two black socks, and two green socks. once a sock it is not replaced. determine the probability.
1. p(a black sock and then a green sock)
2. p(two blue socks)
3. p(a green sock and then a red sock)
4.p(two green socks)
Answers
Answer:
p(a black sock and then a green sock)
The probability of drawing a black sock first is 2/8=1/4, and then the probability of drawing a green sock next is 2/7=2/14 since we have one less sock left. So the overall probability is (1/4) * (2/14) = 1/7
p(two blue socks)
The probability of drawing a blue sock first is 3/8, and then the probability of drawing another blue sock next is 2/7 since we have one less sock left. So the overall probability is (3/8) * (2/7) = 6/56 = 3/28
p(a green sock and then a red sock)
The probability of drawing a green sock first is 2/8, and then the probability of drawing a red sock next is 1/7 since we have one less sock left. So the overall probability is (2/8) * (1/7) = 2/56 = 1/28
4.p(two green socks)
The probability of drawing a green sock first is 2/8, and then the probability of drawing another green sock next is 1/7 since we have one less sock left. So the overall probability is (2/8) * (1/7) = 2/56 = 1/28
Note that these are the theoretical probabilities, and in reality, drawing a sock and not replacing it will change the number of socks left, so the probability of the next draw will change accordingly.

A triangular prism is attached to a rectangular prism as shown below.If W= 6 1/5th inches, x= 5 inches, y= 20 inches, and z=8 3/4th inches, what is the surface area of the figure
Answers
Answer: To find the surface area of the figure, we need to add up the areas of all the individual faces. The triangular prism has three rectangular faces and three triangular faces, and the rectangular prism has six rectangular faces.
The triangular prism:
The area of one of the rectangular faces is (x * z)/2 = (5 * 8.75)/2 = 21.875 inches^2
The area of one of the triangular faces is (x * W)/2 = (5 * 6.2)/2 = 15.5 inches^2
The rectangular prism:
The area of one of the rectangular faces is x * y = 5 * 20 = 100 inches^2
So, the total surface area of the figure is
(3 * 21.875) + (3 * 15.5) + (6 * 100) = 65.625 + 46.5 + 600 = 712.125 inches^2
So the surface area of the figure is 712.125 inches^2

Answers
The exact length (in inches) of the arc of a circle formed by given angle (in radians) and radius is 5.233 inches.
The radius of a circle and the central angle determine the length of an arc. We are aware that given an angle of 360 degrees, the arc length corresponds to the circumference. Thus, the arc length is determined by multiplying the radius by the Centre angle (in radians).
Arc length = radius x angle(in radians)
Radius = 2 inches
Angle = 5pi/6 radians
Arc length = 2 x (5pi/6)
= 5.233
Hence, the arc length is 5.233 inches.

What is sum of interior angles?A polygon's interior angle is the angle created between its two adjacent sides. Alternately, we may state that the internal angle of a polygon refers to the angle measured at the interior portion of a polygon.
For figure 2 the two lines are parallel to each other, and the line that meets the parallel line at points at M and L are from two equal lines.
Hence, the angle suspended by both are equal, that is:
∠L = ∠M
∠L = 23 degrees.
Now, the ∠K and ∠J are created by two parallel lines; hence they are equal:
∠K = ∠J = x
The sum of interior angles of a quadrilateral is 360, so:
∠L + ∠M + ∠J + ∠K = 360
23 + 23 + x + x = 360
46 + 2x = 360
2x = 360 - 46
x = 157
Hence, the measure of angle K and L is 157 and 23 respectively.
For the second figure, the angle K and L are created by equal length of segments.
∠K = ∠L = x
The sum of interior angles of a quadrilateral is 360, so:
∠L + ∠M + ∠J + ∠K = 360
x + 90 + 130 + x = 360
2x + 220 = 360
2x= 360 - 220
x = 70

Answers
The cost of one belt is $53 and the cost of one wallet is $ 73.
What is the cost of each item?The first step is to set up a system of equation using the information in the question:
20w + 14b = 2202 equation 1
20w + 83b = 5859 equation 2
Where:
b= number of belts sold
w = number of wallets sold
In order to determine the value of b, take the following steps:
Subtract equation 2 from equation 1 :
69b = 3657
Divide both sides of the equation by 69
b = 3657 / 69
b = 53
Substitute for b in equation 1:
20w + 14(53) = 2202
20w + 742 = 2202

helpp pls! find the value of each variable in the parallelogram.
Answers
The value of each variable in the parallelogram is h = 9 and g = 59.
What is a parallelogram?A parallelogram is a geometric object with sides that are parallel to one another in two dimensions. It is a form of polygon with four sides (sometimes known as a quadrilateral) in which each parallel pair of sides have the same length. A parallelogram has neighboring angles that add up to 180 degrees. Angles on either side are equal.
We know that the opposite sides of a parallelogram and the opposite angles of a parallelogram are equal.
Using the above statement, we can write:
16 - h = 7
16 - 7 = h
h = 9
g + 4 = 63
g = 63 - 4
g = 59
Hence, the value of each variable in the parallelogram is h = 9 and g = 59.

please convert 1/6 to a decimal probability and round to 2 decimal places students often get exam questions wrong, since they convert to a whole number. you can only do this if you include the ____ %.
Answers
You can only convert 1/6 to a decimal probability and round to 2 decimal places if you include the percentage sign (%) at the end.
When converting fractions to decimal probabilities, it is important to include the percentage sign (%) at the end. This is because when converting a fraction to a decimal, the result is not a whole number, but a decimal probability. For example, 1/6 can be written as a decimal probability of 0.17, but it is usually written as 0.17% to indicate the probability of an event occurring. The percentage sign is essential for students to understand that the decimal is a probability, rather than an incorrect answer. Percentage sign also allows the decimal to be rounded to two decimal places, giving a more precise answer. Without the percentage sign, the decimal will appear to be a whole number, which is not the correct answer.
