Answer:
The ratio that is correct is 5/24.
The error that leads to the incorrect ratio is working with the different units of length.
Step-by-step explanation:
Here is the complete question:
A covered bridge is 8 yards long. In a painting for sale at a gallery, the bridge is 5 feet long. A customer wants to know the ratio of the length of the bridge in the painting to the actual length of the bridge. One salesperson says the ratio in simplest form is 5/8 Another salesperson says the ratio in simplest form is 5/24 Which ratio is correct? What error leads to the incorrect ratio?
Step-by-step explanation:
From the question,
A covered bridge is 8 yards long and in a painting at the gallery, the bridge is 5 feet long.
To determine the ratio of the length of the bridge in the painting to the actual length of the bridge,
First, we will convert both lengths to the same unit and then divide the length of the bridge in the painting by the actual length of the bridge.
Convert 8 yards to feet
1 yard = 3 feet
∴ 8 yards = (8 × 3) feet = 24 feet
The actual length of the bridge is 24 feet
The length of the bridge in the painting is 5 feet
Hence, the ratio of the length of the bridge in the painting to the actual length of the bridge is 5 feet ÷ 24 feet = 5/24
Hence, the ratio that is correct is 5/24.
The error that leads to the incorrect ratio is working with the different units of length (that is, not converting both length to the same unit before determining the ratio).

Answer:
Positive; Negative
Step-by-step explanation:
That is what mine showed for the same question and answer options.
As x approaches positive infinity, m(x) approaches positive infinity.
As x approaches negative Infinity, m(x) approaches negative Infinity.
The function f(x) = x^3 has been transformed m(x) = 1/3x^3+ 6. Than the blank space to be field.
Range of the function is the output value of the function.
Here, f(x) = x^3 transformed to m(x) = 1/3x^3+ 6,
The range of the transformed function is given by for its Domain x = (-∞,∞) is (-∞, ∞).
Thus, the range of the of m(x) for x =(-∞, ∞) is (-∞, ∞).

Which recursive formula can be used to determine the total amount of money earned in any year based on the amount earned in the previous year?
f(n + 1) = f(n) + 5
f(n + 1) = 5f(n)
f(n + 1) = 1.05f(n)
f(n + 1) = 0.05f(n)
Answer:
f(n + 1) = 1.05f(n)
Step-by-step explanation:
The total amount of money earned in any year based on the amount earned in the previous year is f(n+1) = 1.05f(n).
What is annual interest rate?The interest rate is the amount a lender charges a borrower and is a percentage of the principal—the amount loaned.
What is principal?Principal is the money that you originally agreed to pay back. Interest is the cost of borrowing the principal.
According to the question,
The annual interest rate is 5%
So, suppose the amount earned in the previous year is f(n).
The total amount of money earned in any year based on the amount earned in the previous year is
f(n+1) = f(n) + 5%f(n) (principal + interest)
f(n+1) = 1.05f(n)
Hence, the total amount of money earned in any year based on the amount earned in the previous year is f(n+1) = 1.05f(n).

Are the two triangles similar? If so, state the reason and the similarity statement. (See attached image)
A. Yes; AA; ΔLFT ∼ ΔORT
B. The triangles are not similar.
C. Impossible to Determine
D. Yes; SSS; ΔLFT ∼ ΔORT
Answer: They are not similar
Step-by-step explanation: Only way is AAA and AAA doesn’t prove triangles congruent or similar
Option (C) impossible to determine is the correct answer.
What is triangle similarity?Two triangles are said to be similar, if corresponding sides of the two triangles has same ratio or the corresponding angles of the two triangles are equal.
For the given situation,
The diagram has two triangles but the length of the sides and the angles of the triangles are not provided. So we cannot find the similarity between these two triangles.
Hence we can conclude that option (C) impossible to determine is the correct answer.

determine if the equation y=2/7x represents a direct variation
Answer:
Represents a direct variation
Step-by-step explanation:
y = 2/7x
To find x-intercept/zero, substitute
y = 0
0 = 2/7x
Multiply both sides of the equation by 7/2
0 = x
Swap the sides of the equation
x = 0
Solution
x = 0
This is a direct variation because when x = 0. Y has to = 0 as well and it is so that makes this equation a direct variation.
direct variation - mathematical relationship between two variables that can be expressed by an equation in which one variable is equal to a constant times the other

∆ABC is translated 2 units down and 1 unit to the left. Then it is rotated 90° clockwise about the origin to form ∆A′B′C′. The coordinates of vertex A′ of ∆A′B′C′ are . The coordinates of vertex B′ of ∆A′B′C′ are . The coordinates of vertex C′ of ∆A′B′C′ are .
Answer:
A'(-2, 1), B'(1, 0), C'(-1, 0)
Step-by-step explanation:
Transformation is the movement of a point from its initial location to a new location. Types of transformation are rotation, reflection, dilation and translation.
If a point X(x, y) is translated a units right and b units down, the new location is X'(x + a, y + b) whereas if a point X(x, y) is translated a units left and b units up, the new location is X'(x - a, y - b).
If a point X(x, y) is rotated 90° clockwise about the origin, the new location is X'(y, -x)
From the image attached, ∆ABC is at A(0, 0), B(1,3) C(1, 1)
If ∆ABC is translated 2 units down and 1 unit to the left (x - 1, y - 2), the vertices would be A*(-1, -2), B*(0, 1), C*(0, -1)
If it is then rotated 90° clockwise about the origin, the new location is A'(-2, 1), B'(1, 0), C'(-1, 0)
Answer:
The coordinates of vertex A′ of ∆A′B′C′ are (-2, 1) .
The coordinates of vertex B′ of ∆A′B′C′ are (1, 0) .
The coordinates of vertex C′ of ∆A′B′C′ are (-1, 0) .

A pet store was selling 2 lizards for
$14.48. If they ended up selling 6
lizards, how much money would they
have earned?
Answer:
43.44
Step-by-step explanation:
If they are selling 2 lizards for 14.48 you would divide
14.48 by two which is 7.24.
This means the lizards are 7.24 each.
7.24x6 is 43.44
Answer:
$43.44
Step-by-step explanation:
If two lizards are worth $14.48, then you just need two multiply the cost by three.
What is the solution to the linear equation?
4b + 6 = 2 – b + 4
Answer:
b = 0
Step-by-step explanation:
Subtract 6 from both sides:
4b = 2 - b - 2
Subtract 2 from two, and get 0.
4b = -b
this means that the only possible case where the equation is satisfied is when b = 0, because -0 is 0, and 4x0 is still 0.
