the volume of the pot.
solution:bolume of a triangular prism= BH
area of a triangle= 1 / 2 × base × height
B = 1 / 2 × b × h
b = 3 units
h = 5 units
B = 1 / 2 × 3 × 5

Answer: C) [tex]f^{-1}(x)=3-7x[/tex]
Step-by-step explanation:
When solving for an inverse of a function replace f(x) with x and replace the original x with y.

Now solve for y

At school, Akihiro draws a model of the flag of Japan in the coordinate plane.
What is the perimeter of the flag Akihiro draws?
The perimeter of the flag Akihiro draws is the sum of the flag's side lengths
The perimeter of the flag Akihiro draws is 20 units
How to determine the perimeter of the flag?From the coordinate plane, the side lengths of the flag are:
6 units, 4 units, 6 units and 4 units
Add up the side lengths, to determine the perimeter (P)
P = 6 units + 4 units + 6 units + 4 units
Evaluate the sum
P = 20 units
Hence, the perimeter of the flag Akihiro draws is 20 units

Determine the coordinate of the point where
y=3x+6 crosses the x-axis.
Answer:
(- 2, 0 )
Step-by-step explanation:
to find where the line crosses the x- axis, let y = 0 in the equation and solve for x.
0 = 3x + 6 ( subtract 6 from both sides )
- 6 = 3x ( divide both sides by 3 )
- 2 = x
the line crosses the x- axis at (- 2, 0 )
Instead of y write 0:
0=3x+6
Now all we have to do is solve for x :0=3x+6
Subtract 6 on both sides :
-6 = 3x
Switch the order :
3x = -6
Divide by 3 on both sides :
x = -2
Now that we know the x coordinate of the point, we should find the y coordinate, which is always equal to 0.
Coordinates of the point ↓(-2, 0)

How are samples classified?Samples may be classified as:
Convenient: Drawn from a conveniently available pool.Random: All the options into a hat and drawn some of them.Systematic: Every kth element is taken. Cluster: Divides population into groups, called clusters, and each element in the cluster is surveyed.Stratified: Also divides the population into groups. Then, a equal proportion of each group is surveyed.In this problem, he wants a systematic sampling, hence he should choose every kth word, which means that the answer is between options a and b.
He will choose 500 words out of 100,000, hence the value of k is given by:
k = 100000/500 = 200.

The graph of polygon FGHI has coordinates F(2. – 1), G(5,2), H(8, 3), and I(6, 0). Graph the image of FGHI
after a reflection across the line y = -1.
Part A
Graph the line of reflection
Part B
Graph FGHI and its reflection across the line y = -1
Reflecting the polygon FGHI across the line involves flipping the line across the line y = -1
How to reflect the polygon?The coordinates are given as:
F(2, – 1), G(5,2), H(8, 3), and I(6, 0)
The line of reflection is given as:
y = -1
To reflect the line, we apply the following rule of reflection

A scale model of a large, three-dimensional “real world” object uses a scale of 0.5 in. = 50 ft.
Fred was only able to measure the model using metric units. He measured the length of the model as 372.5 mm.
Fred knows that 1 inch = 2.54 cm and that 1 cm = 10 mm.
What is the approximate length of the actual “real world” object?
A.
244.3 ft
B.
122.2 ft
C.
2,932 ft
D.
1,467 ft
The approximate length of the actual object is 1465 ft, which is closest to option D.
What is a scale factor?The ratio of the scale of an original thing to a new object that is a representation of it but of a different size is known as a scale factor (bigger or smaller).
First, let's convert the length of the model from millimeters to inches:
372.5 mm = 372.5/10 cm = 37.25/2.54 in ≈ 14.65 in
Next, we can use the scale of the model to find the length of the actual object in feet:
0.5 in. = 50 ft.
So, 1 in. = 100 ft.
Therefore, the length of the actual object in feet is:
14.65 in x (100 ft/in) = 1465 ft
Therefore, the closest length is 1467 feet.

The vertices of a rectangle are E(−1, 1), F(−1, 3), G(−5, 3), and H(−5, 1). Find the coordinates of the figure after reflecting in the x-axis, and then translating 3 units right.
The resulting points of the rectangle after applying rigid transformations are E'(x, y) = (2, -1), F(x, y) = (2, -3), G(x, y) = (-2, -3), H(x, y) = (-2, -1).
How to apply rigid transformations on geometrical loci
Rigid transformations are transformations in which Euclidean distances are conserved in every point of the geometrical locus. Reflections and translations are sound examples of rigid transformations.
Based on all the information given in the statement, we must apply the following vectorial formula to each vertex of the rectangle EFGH:
(x', y') = (x + 3, -y) (1)
If we know that E(x, y) = (-1, 1), F(x, y) = (-1, 3), G(x, y) = (-5, 3) and H(x, y) = (-5, 1), then the new coordinates are calculated below:

find the equation of a straight line which is parallel to the line with equation 5x+7y=14 and passes through a point (-2,-3)
Answer:
[tex]7y=-5x-11[/tex]
Step-by-step explanation:
Since it says the lines are parallel both of their gradients will be same.
so gradient of line 1 = [tex]y=\frac{14-5x}{7}[/tex] = [tex]y=\frac{14}{7}-\frac{5x}{7}[/tex]= [tex]-\frac{5}{7}[/tex]
so equation of line 2 = [tex]y-y_{1}=m(x-x_{1} )[/tex]
= [tex]y-(-3)_{}=\frac{-5}{7} (x-(-2)_{} )[/tex]
= [tex]y +3=-\frac{5}{7}x+\frac{10}{7}[/tex]
= [tex]y =-\frac{5x+10}{7}-3[/tex]
= [tex]7y=-5x-11[/tex]
Step-by-step explanation:
basically a line equation typically looks like
y = ax + b
with a being the slope, and b bent the y-intercept (y value when x = 0).
5x + 7y = 14
7y = -5x + 14
y = -5/7 x + 14/7 = -5/7 x + 2
so, wie know the slope of the original line : -5/7 .
any line parallel to it must have the same slope.
our desired line looks like
y = -5/7 x + b
to get b we use the provided point (-2, -3).
-3 = -5/7 × -2 + b = 10/7 + b
-21/7 = 10/7 + b
-31/7 = b
and the full equation is
y = -5/7 x - 31/7
7y = -5x - 31
5x + 7y = -31

What is addition?Addition is one of the four basic operations of arithmetic, The addition of two whole numbers results in the total amount or sum of those values combined.
Addition is the process of finding the total, or sum, by combining two or more numbers.
An example of addition is: 5 + 11 + 3 = 19.
Given that, Roy bought a 25 pound bag and a 10 pound bag of pet food we need to find that how many pounds of pet food did he buy
Since, we are required to find what amount of pet food did Roy bought from the market, here we will simply add both the amounts to get the total amount.
Total food = 25 pound bag + 10 pound bag

What is 7/8 - 1/4 in simplest form?
Answer: 5/8
Step-by-step explanation:
You could convert 1/4 to 2/8 because the numbers you're subtracting have a common factor of 2. After subtracting 2/8 from 7/8, you're left with 5/8.
Answer:
7/8 - 1/4 = 5/8
Step-by-step explanation:
The equation is 7/8 - 1/4 = ?
So you need to have a common denominator for both fractions in order to subtract the two.
In order to make 7/8 and 1/4 have a common denominator, multiply 1/4 by 2. Then it becomes 2/8.
Now you can subtract the two fractions because they both have a common denominator.

Order: abc 1500 mg. stock: abc 2.2 g/3 ml. how many ml(s) will you give? (round the answer to the nearest tenth)
The amount of ml required for the 1500mg order is 2.1ml
Conversion of grams to milligramConversion factors are used to convert units from one form to another.
Using the conversion factor
2.2g = 2200mg
x = 1500mg
Find the ratio of the expressions
2.2/x = 2200/1500
2200x = 2.2 * 1500
2200x = 3300
X = 3300/2200
x = 1.5grams
Since the dosage is 2.2 g/3 ml, then for 1.5grams
