Based on the calculations, the surface area of this rectangular prism is equal to 49,408 square inches.
Given the following data:
Length of this rectangular prism = 114 feet.Width of this rectangular prism = 8 inches.Height of this rectangular prism = 10 inches.What is an equation?An equation can be defined as a mathematical expression which shows that two (2) or more thing are equal.
How to calculate the surface area of a rectangular prism?Mathematically, the surface area of a rectangular prism can be calculated by using this equation or formula:
SA = 2(WH + LW + LH)
Where:
SA represents the surface area of a rectangular prism.L represents the length of a rectangular prism.W represents the width of a rectangular prism.H represents the height of a rectangular prism.Conversion:
1 feet = 12 inches
114 feet = L inches
Cross-multiplying, we have:
L = 12 × 114
L = 1,368 inches.
Substituting the given parameters into the formula, we have;
SA = 2(8 × 10 + 1,368 × 8 + 1,368 × 10)
SA = 2(80 + 10,944 + 13,680)
SA = 2(24,704)
SA = 49,408 square inches.

Triangle ABC is transformed to Triangle XYZ. If A(2, 4), B(-1, 0), and C(3, -7) are the points given... The following transformations occured: Refection over the line y=x, rotation 90° counterclockwise, and translation (x + 2, y - 5). Where will point Y be after the transformation? Y( , )'
Points of the triangle ABC after rotating counter-clockwise 90° and translation of [(x+2),(y-5)] will be a triangle XYZ which has points of XYZ, X(6,-7), Y(2,-4), and Z(-5,-8).
What are translations?Translations are of 4 types they are rotation, dilation, translation and reflection.
We know when the rotation of 90° counter-clockwise takes place we switch the coordinates (x,y) to (y,x) and make x negative which is (y,-x).
Given a triangle ABC with points A(2, 4), B(-1, 0), and C(3, -7) rotated 90° to form another triangle XYZ.
∴ Points of triangle XYZ will be X(4,-2), Y(0,1), and C(-7,-3).
Now we translate these points by [(x+2),(y-5)].
∴ Points of triangle XYZ will be X(6,-7), Y(2,-4), and Z(-5,-8).

It is possible for one person's weight to be 500% more than another person's weight.
Answer:
it's true because
4-x/3= y solve for x
Answer:
x=-3y+12
Step-by-step explanation:
[tex]4-\frac{x}{3}=y[/tex]
You can subtract y from both sides and add (x/3) to both sides to isolate the variable that you're trying to solve.
[tex]-y+4=\frac{x}{3}[/tex]
Multiply both sides by 3

What is true about the rate of change for this situation?
Choose the correct answer from the drop-down menu to complete the statement.
Elizabeth used
ounces of vinegar to make 1 batch of salad dressing. Elizabeth used blank ounces of vinegar to make 1 batch of salad dressing
Answer:
7 ounces
Step-by-step explanation:
You divide 28 by 4 which would equal to 7 ounces per batch.
Elizabeth used 7 ounces of vinegar to make 1 batch of salad dressing.
Given that Elizabeth uses 28 ounces of vinegar to make 4 batches of salad dressing.
We need to determine the rate of change for this situation.
To find the number of ounces of vinegar Elizabeth used to make 1 batch of salad dressing, we need to divide the total amount of vinegar (28 ounces) by the number of batches (4).
The rate of change for this situation is the amount of vinegar used per batch.
Let's calculate it:
Vinegar used per batch = Total vinegar used / Number of batches
Vinegar used per batch = 28 ounces / 4 batches
Vinegar used per batch = 7 ounces
So, Elizabeth used 7 ounces of vinegar to make 1 batch of salad dressing.

Find the equation of the line that is parallel to -x+2y=7 and passes through (4,3)
the equation of the line that is parallel to the line - x + 2 y = 7 is - x - y + 7 = 0.
We know that, if the lines are parallel, then their slopes are equal.
We have the line:
- x + 2 y = 7
Slope = - 1
Now, we have the point ( 4, 3)
So, the equation of the line will be:
y - y₁ = m ( x - x₁ )
Substituting the values, we get that:
y - 3 = - 1 ( x - 4 )
y - 3 = - x + 4
x + y - 3 - 4 = 0
x + y - 7 = 0
- x - y + 7 = 0
Therefore, the equation of the line that is parallel to the line - x + 2 y = 7 is - x - y + 7 = 0.

−5x+2y=−19 please help
Answer:
-9.5, -7, 5
Step-by-step explanation:
We need to make this a readable function. We will change it to slope-intercept form, y = mx + b. to do this, we must isolate the variable y.
-5x + 2y = -19
-5x + 2y + 19 = -19 + 19
-5x + 2y + 19 = 0
-5x + 2y - 2y + 19 = -2y
-5x + 19 = -2y
We are solving for positive y, so we will flip all signs in the equation.
5x + - 19 = 2y
5x/2 - 19/2 = 2y/2
2.5x - 9.5 = y
y = 2.5x - 9.5
There's our y = mx + b. We now need to solve for each ordered pair.
y = 2.5(0) - 9.5
y = -9.5
(0, -9.5)
y = 2.5(1) - 9.5
y = 2.5 - 9.5
y = -7
(1, -7)
2.5x - 9.5 = 3
2.5x - 9.5 + 9.5 = 3 + 9.5
2.5x = 12.5
2.5x/2.5 = 12.5/2.5
x = 5

The equation is also reference to volume of a cone. To solve an equation for h-term, we’ll multiply both sides by 3 first to clear all denominator:

1.2 gallons of water should be added to 1 gallon of antifreeze to make it a solution which have 45% of antifreeze.
What is percentage ?Percentage is the value per hundredth.
According to the given question we have to determine how much water should be added to 1 gallon of pure antifreeze to obtain a solution that is 45% antifreeze.
To obtain a 45% antifreeze solution we need (100-45)% = 65% water.
Let us assume that the total mix is of x gallons which contains 45% antifreeze.
∴ The total mix in gallons which contains 45% antifreeze and have 1 gallon of antifreeze is
(45/100)x =1.
0.45x = 1
x = 1/0.45
x= 2.22 gallons of total mix.
∴ Water in this mix which have 45% of antifreeze is (2.22 - 1) gallons which is = 1.22 gallons of water.

The y-intercept of the given line is -1/2
Y-Intercept means the line making an intercept on the y-axis where the value of x will be 0.
In simple terms, the Y-intercept of any line can be found by making x = 0
The equation of the line given is
20x + 20y = -10
So to find the y-intercept, let us keep x = 0
Thus, the equation becomes
20(0) + 20y = -10
0 + 20y = - 10
20y = -10
y = -10/20
y = -1/2
y = -0.5

You jump off a diving board
into a pool. You reach a maximum height of 25 feet
after traveling 1 foot horizontally, and hit the water
6 feet from the diving board. The path of your dive
can be modeled by a parabola, where y is the height
(in feet) and x is the horizontal distance traveled (in
feet). What is the height of the diving board?
Finding the equation of the parabola, it is found that the height of the diving board is of 24 feet.
What is the equation of a parabola given it’s vertex?The equation of a quadratic function, of vertex (h,k), is given by:
y = a(x - h)² + k
In which a is the leading coefficient.
From the maximum height, it is found that the vertex is at (1,25), hence:
h = 1, k = 25.
Hence:
y = a(x - 1)² + 25.
You hit the water 6 feet from the diving board, hence y(6) = 0, meaning that we use it to find a as follows:
0 = a(6 - 1)² + 25
25a = -25.
a = -1.
Hence:
y = -(x - 1)² + 25.
The height of the diving board is y(0), hence:
y = -(0 - 1)² + 25 = -1 + 25 = 24 feet.
