I need a minimal of 3 paragraphs explain how the problem was solved and if it’s correct, please help!
That is a question about spatial geometry.
In our problem, we have to calculate lateral surface area of a triangular prism. Let's see how to solve this.
A triangular prism has 5 faces: 3 equals rectangles and 2 equals triangles. If we can find a way to calculate those areas, we can solve the problem.
The first thing that we should note is that we know the dimensions of the rectangular faces. The dimesions of the rectangular are 5cm and 8cm. To calculate the are of a rectangle, we multiplicate the dimensios of it. Therefore, each rectangle (in our problem) has [tex]5 \times 8 = 40cm^2[/tex] of area. There are 3 rectangles, so, the sum of the 3 rectangular area is [tex]40 + 40 + 40 = 120cm^2[/tex].
Now, we need to know the area of the triangular areas. To calculate the area of a triangle, we need to know the value of the base and the value of the height.
In the image, we know the value of the base, but we do not know the value of the height. To calculate the height, we can use the Pythagorean Theorem because we have a right triangle. (Please find attached the document.)
The Pythagorean theorem says that:
[tex]\boxed{a^2 = b^2 + c^2}[/tex]
a is the hypotenuse and b and c are cathetus.
In this right triangle, the value of the hypotenuse is 5cm and the value of one cathetus is the half of 6cm (that is 3cm). Let's replace the values in the expression:
[tex]a^2=b^2+c^2\\5^2= 3^2 +c^2\\25 = 9 + c^2\\c^2 = 25 - 9\\c^2 = 16\\c = \sqrt{16} \\c = 4cm[/tex]
Now, we know the bases and the height of the triangular areas. To calculate the area of a triangle, we multiply the base and the height and we divided the result by 2. See the expression:
[tex]\boxed{A_t=\frac{b\times h} {2}}[/tex]
b is the base and h is the height. Let's replace the values in the expression:
[tex]A_t = \frac{b\times h}{2} \\A_t = \frac{6\times4}{2} \\A_t = \frac{24}{2} \\A_t = 12cm^2[/tex]
So, each triangular area has 12cm² of area. Therefore, the sum of the triangular areas is [tex]12 + 12 = 24cm^2[/tex].
Finally, we know that the sum of the rectangular area is 120cm², and the sum of the triangular area is 24cm², so, the lateral surface area is [tex]120 + 24 = 144cm^2[/tex].
In other words, they didn't choose the correct answer because the correct answer is J) 144 cm².
I hope I've helped. :D

Answer:
7+5+12+2+9+2+3=40mn
Answer:
4mn - 6
Step-by-step explanation:
expressions => (-7mn) + 5, 9mn - 8, -2mn - 3
In addition, we get..... (-7mn + 9mn - 2mn) + (-3 - 8 + 5)
4mn + (-6)
=> 4mn - 6

A rectangular swimming
pool has a perimeter of
150 meters. The length of
the pool is twice the width
of the pool. What is the
length of the pool?
Answer:
77
Step-by-step explanation:
perimeter=150
lets name the length x
length=x
width=x-2
2[x±x-2]=150
2x±2x-4=150
4x=154
154÷4=77
x=77
The length of the pool is 50 meters and this can be determined by using the formula of the perimeter.
Given :
A rectangular swimming pool has a perimeter of 150 meters. The length of the pool is twice the width of the pool.The following steps can be used in order to determine the length of the pool:
Step 1 - The formula of the perimeter of the rectangle is given by:
P = 2(l + w)
where l is the length of the rectangle and w is the width of the rectangle.
Step 2 - According to the given data, the length of the pool is twice the width of the pool that is:
l = 2w --- (1)
Step 3 - Now, substitute the known terms in the formula of the perimeter.
150 = 2(3w)
150 = 6w
w = 25 meters
Step 4 - Now, substitute the value of w in the equation (1).
l = 2(25)
l = 50 meters.

find the volume of metal required to make a closed box of thickness 1 cm with external measurements 12 cm × 7 cm × 10
Answer:
The volume of the metal is:
[tex]V_{t}=548\: cm^{3}[/tex]
Step-by-step explanation:
First, let's find the volume of the front face of the square:
[tex]V_{1}=12*7*1=84\: cm^{3}[/tex]
The back face is the same, so we have:
[tex]V_{2}=84\: cm^{3}[/tex]
The volume of the side faces will be:
[tex]V_{3}=7*10*1=70\: cm^{3}[/tex]
[tex]V_{4}=70\: cm^{3}[/tex]
And finally, the volume of the top and bottom side faces of the box will be:
[tex]V_{5}=12*10*1=120\: cm^{3}[/tex]
[tex]V_{6}=120\: cm^{3}[/tex]
The total volume of the metal will be:
[tex]V_{t}=V_{1}+V_{2}+V_{3}+V_{4}+V_{5}+V_{6}[/tex]
[tex]V_{t}=2(84)+2(70)+2(120)[/tex]
[tex]V_{t}=548\: cm^{3}[/tex]

I NEED HELP ASAP!! I'LL GIVE BRAINLIEST TO THE CORRECT ANSWER!!!
Answer:
because this is a parallelogram
=> b - 10 + b + 10 = 180
<=> 2b = 180
=> b = 90
with b = 90 => b - 10 = 80
b + 10 = 100
we also have:
d = b + 10 => d = 100
c = b - 10 => c = 80

The coordinates of triangle QRS are Q(-2, 4), R14,0) and S(6,2). The figure was dilated and the new coordinates are Q(-3, 6), R'(6,0) and S'(9,3). What is the scale factor? What is the algebraic rule?
Answer:
Scale factor is 3/2
Step-by-step explanation:
Just take any coordinate of any point that was scaled and that had a non-zero initial value. Let’s take the x axis of Q. There’s [tex]x_Q = -2 \land x_{Q'} = -3[/tex].
So, the scaling factor has to be [tex]\frac{x_{Q'}}{x_Q} = \frac{-3}{-2} = \frac{3}{2}[/tex]. You can confirm that [tex]\frac{x_{Q'}}{x_Q} = \frac{y_{Q'}}{y_Q} = \frac{x_{R'}}{x_R} = \frac{x_{S'}}{x_S} = \frac{y_{S'}}{y_S}[/tex]. (I omitted [tex]\frac{y_{R'}}{y_R}[/tex] because of zero values)
The algebraic rule for getting the point [tex]P'(x_{P'}, y_{P'})[/tex] in the dilated space from any given point [tex]P(x_P, y_P)[/tex] is [tex]\left \{ {{x_{P'} = \frac{3}{2}x_P} \atop {y_{P'} = \frac{3}{2}y_P}} \right.[/tex]

Which tree diagram shows all the possible outcomes that Marissa can get
when she spins the arrow twice?
Explanation:
In this answer choice, we effectively have two columns. In the first column is simply R and B, with R over B. This represents spinning either red (R) or blue (B).
Depending on the outcome, you branch the same outcomes from that.
So if you spin R, then you'll have R and B branch off that. Same idea applies to blue as well.
Something like choice D doesn't work because we have R show up twice at the very bottom.
The tree diagram shows all the possible outcomes that Marissa can get
when she spins the arrow twice is choice D.

Answer:
B. 3x and 8x
Step-by-step explanation:
if you look closely at this expression you'll notice that each polynomial is almost all different except for 3x and 8x because they share the same unknown variable. you couldn't choose 8 because that is just a whole number and all the other numbers contain a variable. and you couldn't choose 3y because y only affects the 3 in this expression whereas x affects 3x and 8x therefore the right answer is 3x and 8x which are the like terms.

A quadratic function has a vertex of (0,7) and passes through the point (2, 3). Which of
the following is the equation of the graph of the quadratic function?
Answer:
Y = -2X + 7
Step-by-step explanation:
Y = a(x-h)^2 + k
From (h,k) h = 0 k = 7 x = 2 y = 3
3 = a(2-0) + 7
3 = 2a - 0 + 7
Collect like terms
2a = 3 - 7
2a = -4
Divide both sides by 2
2a/2 = -4/2
a = -2
y = a(x-h) + k
y = -2(x-0) + 7
y = -2x + 0 + 7
y = -2x + 7 or
y + 2x - 7 = 0
