The required surface area of the rectangular prism is 461.02 square meters (m²).
What is surface area?Surface area is defined as the measure of a region or surface is called as surface area.
The surface area of a rectangular prism can be calculated by adding up the areas of all six faces. The formula for the surface area of a rectangular prism is:
Surface area = 2lw + 2lh + 2wh
where l, w, and h are the length, width, and height of the rectangular prism, respectively.
Substituting the given values, we get:
Surface area = 2(12.3m x 4.3m) + 2(12.3m x 10.7m) + 2(4.3m x 10.7m)
Simplifying the expression gives:
Surface area = 461.02m²
Therefore, the surface area of the rectangular prism is 461.02 square meters (m²).

solve x/2 +3 > 4
Answer:
x >2
Step-by-step explanation:
x/2 +3 > 4
Subtract 3 from each side
x/2 +3-3 > 4-3
x/2 >1
Multiply each side by 2
x/2*2 >1*2
x >2
Answer:
x > 2
Step-by-step explanation:
A linear inequality is given to us and we need to find the interval of x. The given inequality is
⇒ x/2 + 3 > 4
Subtract 3 to both sides,
⇒ x/2 + 3 - 3 > 4 -3
⇒ x/2 > 1
Multiply both sides by 2 ,
⇒ x > 2
Hence x can have all values more than 2 .
Instructions: Determine whether the following polygons are similar. If yes, type in the similarity statement and scale factor. If no, type 'None' in the blanks.
Similar: _____
Similarity Statement: ____ ∼ ____
Scale Factor: _____
Answer:
The polygons are not similar..
Step-by-step explanation:
We have given the two polygons which are parallelogram with the opposite sides 10.4 units, 3.74 units, 4 units and 1.7 units
For the polygons to be similar, ratios of both the polygons must be equal.
Lets check whether the two polygons are equal or not.
10.4/3.74 = 2.78
4/1.7 = 2.35
Therefore it is proved that both the polygons are not similar because both these ratios are not equal....

y equals 0.75 x plus 4
y equals 4 x plus 0.75
y equals minus 4 x plus 1
y equals 0.75 x plus 1
Answer:
y = 3/4 x + 4
y equals 0.75 x plus 4
Step-by-step explanation:
y = 3/4 x + b
1 = 3/4 (-4) + b
1 = -3 + b
b = 4
Answer:
A) y equals 0.75 x plus 4Step-by-step explanation:
Another way to solve this to use the point-slope form:
y - y₁ = m(x - x₁)Substitute the values of m, x₁, y₁ and convert this into slope-intercept form:
y - 1 = 3/4(x - (-4))y - 1 = 3/4x + 3y = 3/4x + 4y = 0.75x + 4Correct choice is A

Answer:
D.
Step-by-step explanation:
According to converse of the Pythagorean Theorem, that if the square of the third side (longest side) of a triangle equals the sum of the other two shorter sides, therefore, the triangle formed must be a right triangle.
From the side lengths given, the following satisfies the Pythagorean triple:
5² + 12² = 13².
Therefore, the procedure to use to confirm the converse of the Pythagorean Theorem would be to draw the two shortest side, 5 cm and 12 cm, so that a right angle will be between them. The side measuring 13 cm should therefore fit in to form a right triangle.

There are three separate, equal-size boxes, and inside each box there are four separate small boxes, and inside each of the small boxes there are three even smaller boxes. how many boxes are there all together?
Answer:
There are 51 boxes all together.
Step-by-step explanation:
Since there are three separate, equal-size boxes, and inside each box there are four separate small boxes, and inside each of the small boxes there are three even smaller boxes, to determine how many boxes are there all together, the following calculation must be done:
3 + 3 x 4 + 3 x 4 x 3 = X
3 + 12 + 36 = X
51 = X
Therefore, there are 51 boxes all together.

Step-by-step explanation:
How many different license plates are possible if each contains 4 letters (out of the alphabet's 26 letters) followed by 2 digits (from 0 to 9)? How many of these license plates contain no repeated letters and no repeated digits? There aredifferent possible license plates. (Simplify your answer.) There are different possible license plates if no letters or numbers are repeated. (Simplify your answer.)
Answer:
There are 45,697,600 different possible license plates. If no letters or numbers are repeated, there are 32,292,000 possible license plates.
Step-by-step explanation:
For the first question, we can repeat letters and digits.
Let [tex]\ell[/tex] represent a letter and [tex]#[/tex][tex]\#[/tex] represent a digit. The license plate format given is:
[tex]\underline{\ell}\:\:\underline{\ell}\:\:\underline{\ell}\:\:\underline{\ell}\:\:\underline{n}\:\:{\underline {n}[/tex]
For each letter, there are 26 letters to choose from (alphabet). For each digit, there are 10 numbers to choose from (0-9).
Since we're choosing 4 letters and 2 numbers, the number of possible license plates is:
[tex]26\cdot 26\cdot 26\cdot 26\cdot 10\cdot 10=\boxed{45,697,600}[/tex]
If we stipulate that no letter or digit may be repeated, then we'll still have 26 choices for the first letter, but for the second letter, we'll only have 25. Then 24, 23, and so on. Similarly, for the first digit, there will be 10 choices, then 9, 8, and so on.
Therefore, the desired answer for the second part of the question is:
[tex]26\cdot 25\cdot 24\cdot 23\cdot 10\cdot 9=\boxed{32,292,000}[/tex]
*Note that we don't need to account for rearrangements as [tex]HOCL67[/tex] and [tex]CLHO76[/tex] are considered different license plates (order matters).

Answer:
WZY=170°
XYZ=60°
Step-by-step explanation:
Straight line, so WZY=180-10=170
Angles in a quadrilateral add to 360°, so:
100+30+170=300
360-300=60
XYZ=60°
Answer:
170° and 52°
Step-by-step explanation:
∠ WZY and ∠ YZA are adjacent angles and sum to 180° , that is
∠ WZY + 10° = 180° ( subtract 10° from both sides )
∠ WZY = 170°
The sum of the angles in a quadrilateral = 360°
sum the angles and equate to 360
∠ XYZ + 170° + 38° + 100° = 360°
∠ XYZ + 308° = 360° ( subtract 308° from both sides )
∠ XYZ = 52°

If there is a die that has 12 sides, that are numbered 1 to 12, what is the probability that she will roll either a 3 or a 9
Answer:
2/12 = 1/6
Step-by-step explanation:
To find the probability of something with an equal chance of each outcome, we can apply the formula (number of favorable outcomes)/(number of total outcomes). Because there is an equal chance for each side of the die to be landed on, we can apply this.
On a 12 sided die, there are 12 sides. Two of those sides are 3 and 9. Therefore, there are two favorable outcomes (3 and 9). There are 12 sides to choose from, so there are 12 total outcomes, making the probability 2/12 = 1/6

PLEASE HELP ME ITS URGENT , WILL MARK AS BRAINLIEST!!!
Answer:
[tex]\boxed{\sf A) ( 1,0) }[/tex]
Step-by-step explanation:
A quadratic function is given to us and we need to find the x Intercept of the graph of the given function . The function is ,
[tex]\sf \implies f(x) = x^2 -2x + 1 [/tex]
For finding the x intercept , equate the given function with 0, we have ;
[tex]\sf \implies x^2 -2x + 1 = 0 [/tex]
Split the middle term ,
[tex]\sf \implies x^2-x-x+1=0[/tex]
Take out common terms ,
[tex]\sf \implies x( x -1) -1( x -1) = 0[/tex]
Take out (x - 1 )as common ,
[tex]\sf \implies (x - 1 )(x-1) = 0[/tex]
Equate with 0 ,
[tex]\sf \implies x = 1,1 [/tex]
Therefore the root of the function is 1. Hence the x Intercept is (1,0)
Hence the x Intercept is (1,0) .
Step-by-step explanation:
x² - 2x + 1 = 0
x² - (x + x) + 1 = 0
x² - x - x + 1 = 0
x(x - 1) - 1(x - 1) = 0
(x - 1)(x - 1) = 0
x = 1

Hi there!
The quadratic formula: [tex]x=\frac{-b\pm\sqrt{b^2-4ac}}{2a}[/tex] where the given quadratic is in the form [tex]ax^2+bx+c=0[/tex]
From the given equation [tex]4x^2-x-5 = 0[/tex], we can identify the values of a, b, and c:
a=4
b=-1
c=-5
Plug these values into the quadratic formula:
[tex]x=\frac{-(-1)\pm\sqrt{(-1)^2-4(4)(-5)}}{2(4)}\\x=\frac{1\pm\sqrt{81}}{8}[/tex]
[tex]x=\frac{1\pm9}{8}[/tex]
[tex]x=\frac{1+9}{8}= \frac{5}{4} \\x=\frac{1-9}{8} = -1[/tex]
Therefore, the solutions to the quadratic are 5/4 or 1.
