Name one pair of parallel planes. All lines and planes that appear to be parallel are parallel.
The parallel plane is the plane that has the same in-between distance at all points on the plane so plane ABF is parallel with plane DCG so option (C) is correct.
What is the plane?The plane is a two dimension(2D) surface that has a surface area.
We can draw lines on a plane and two or more planes can intersect or parallel.
If two planes are parallel then the perpendicular distance between both planes must be the same.
The angle of inclination of two parallel planes with a single reference plane is also the same.
In the given cuboid the plane ABF is parallel with plane DCG.
So, ABF || DCG.
Hence "The parallel plane is the plane that has the same in-between distance at all points on the plane so plane ABF is parallel with plane DCG".

A skier is trying to decide whether or not to buy a season ski pass. A daily pass costs $61. A season ski pass costs $350. The skier would have to rent skis with either pass for $20 per day. How many days would the skier have to go skiing in order to make the season pass less expensive than the daily passes?
7 days would the skier have to go skiing in order to make the season pass less expensive than the daily passes.
what is Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side. It demonstrates the equality of the relationship between the expressions printed on the left and right sides. Every mathematical equation begins with L.H.S = R.H.S.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Let s be the cost of skiing per day.
So, the season pass plus ski rentals equates to daily skiing plus ski rentals
450 + 20s = 64s + 20s
450 = 64s
7.03 ≈ s
Hence, 7 days would the skier have to go skiing in order to make the season pass less expensive than the daily passes.

A box is used to hold bolts for an assembly line. When there are 40 bolts in the box, the total mass is 280 g. When there are 65 bolts in the box, the total mass is 405 g. Find the mass of the box and the mass of each bolt.
The box contains 40 bolts, each weighing 280 g. The package weighs 405 g when there are 65 bolts inside. The bolt's mass is thus 5g, while the box's mass is 80g.
What makes linear equations significant?In many practical applications in daily life, linear equations are a crucial tool in science.
They let scientists, among other things, make predictions, compute rates, and characterize connections between two variables in the physical world. In order to see trends, linear equations are often graphed.
What exactly is the idea behind solving equations?A condition on a variable is an equation when it ensures that two expressions in the variable have the same value.
The variable’s value for which the equation holds true is referred to as the equation’s solution.
Bolts are kept in a box for an assembly line. The package weighs 280 g when there are 40 bolts inside.
In the event that there are 65 bolts in the box, the total mass is 405 g. Find the mass of the bolt and box.Let ‘x’ be the mass of each bolt and ‘y’ be the mass of the box, then we have:
40x + y = 280(1)
65x + y = 405(2)
If we subtract these 2 equations that are for (2) – (1) we get:
25x = 125
X = 5
Using (1) we get
Y = 280-40x
Y = 280-40*5
Y = 80.
Hence the mass of the bolt is 5g and the mass of the box is 80g.

graph the linear function
Answer:
Step-by-step explanation:
1) First find the y-intercept point
You can find it easily by finding the number without the variable. In this case, it is -1. With this draw a point on the y-axis line down to -1.
2) Find the slope.
Next, you can find a point by substituting a number for x. So in this example, I will be subbing x for 1.
y = -3(1) - 1
y= -3 - 1
y= -4
So there will be a point at (1,-4).
3) Graphing.
After you find that you can easily draw a straight line through both points.

Identify the mistake and explain why the graph of the aggregate expenditures line does not correctly illustrate the economy's equilibrium.
Given that the 45° line is appropriately positioned in the graph, we may conclude that the aggregate expenditure line does not accurately depict the economy's equilibrium. [See attached Image]
What is the explanation for the above answer?The economy reaches equilibrium when the 45° line intersects the Aggregate Expenditure line. It is worth noting that this occurs at a real domestic output of 280, rather than 340, as indicated by the dashed lines in the graph.
It is to be noted that Aggregate spending is a measure of national income in economics. The present value of all finished products and services in the economy is described as aggregate spending. Thus, aggregate spending is the total of all expenditures made in the economy by the factors over a certain time period.

Rollaround skate rink charges $5 admission and $3 per hour for a skate rental. Spinaround skate rink charges $8 admission and $1.50 per hour for a skate rental. Write an equation to determine at what point the cost of both roller skating rinks is the same.
Answer:
2 hours
Step-by-step explanation:
Let x be the time, in hours, for which the cost of Rollaround and Spinaround are the same.
Rollaround Cost (Cr): Cr = $5 + $3x
Spinaround Cost (Cs): Cs = $8 + $1.50x
We want to find the value of x that makes Cr = Cs
Cr = Cs
$5 + $3x = $8 + $1.50x
$1.50x = $3
x = 2 hours
====
CHECK:
Cr = $5+$3(2) = $11
Cs = $8+$1.50(2) = $11
At 2 hours, both cost the same.

A laptop is selling at Digital Direct. The store has an anniversary sale, and everything is 25% off. We have to pay 13% HST on all items purchased from the store. What is the original price of the laptop if you have to pay a total of $677.15 at the cash register?
The original price of the laptop is $479.40.
Given:
Discount on the laptop = 25%
HST paid on the laptop = 13%
Total price of the laptop = $677.15
Let the original price of the laptop be $x.
Price of the laptop after 25% off = x + 25% of x
= $ (125x/100)
Total Price of the laptop after paying 13% HST
= (125x/100) + 13% of (125x/100)
= (125x/100) + (65x/400)
= $ (565x/400)
Now, it is given that the total price paid is $677.15 at the cash register.
565x/400 = 677.15
x = (677.15 × 400)/565
x = $479.40
Therefore, the original price of the laptop is $479.40.

Is y=x(1-x)-(1-x^2) a linear, quadratic, or absolute value
The y=x(1-x)-(1-x²) is a linear value that is not absolute.
Simplifying,
y=x(1-x)-(1-x²)
y=x-x²-1+x²
y=x-1
Thus, it is a linear equation with a negative value therefore it is not an absolute value.
Ax+By=C is the general form of a two-variable linear equation. When the equation is written in this manner, it is quite simple to obtain both segments (x and y).
Any polynomial that can be rewritten in the canonical form is a quadratic equation. where x represents an unknown quantity and a, b, and c represent known quantities, with a = 0.

You have 200 feet of fencing to enclose a rectangular plot that borders on a river (a long side borders the river). If you do not fence the side along the river, find the length and width of the plot that will maximize the area. What is the largest area that can be enclosed?
The maximum Area that can be enclosed will be 5000 square feet.
In the given question, it is stated that 200 feet of fencing will be done to enclose a rectangular plot with borders on a river. It has a long side on the border of a river which does not needs fencing. We need to find out the Length and Width of the plot that will maximize the area and also find out the Maximum area that can be enclosed.
It is given that the total length of the fence is 200 feet.
Let the length of the plot be l
let the width of the plot be w
=> Total Perimeter will be = l + 2w because the longer side or 1 side of length does not need fencing. Putting the perimeter as 200 we get
=> l + 2w = 200 => Equation (1)
Now, we know the Area of the plot will be l*w,
By equation (1) we get l = 200 - 2w, Putting the values in the Area:
=> Area = (200-2w) * w
=> A = 200w - 2w²
For maximum Area, the derivative of A with respect to w will be 0
=> [tex]\frac{dA}{dW} = 200 - 4w[/tex]
=> [tex]0 = 200 - 4w[/tex]
=> w = 50
Putting w = 50 in Equation (1) we get
=> l = 100
We got our Length l = 100 feet, and Width w = 50 feet. Now we will Calculate the maximum Area to enclose.
=> Area = l*w
=> A = 100*50
=> A = 5000
Hence, the Maximum area to enclose will be 5000 square feet.
