A dog takes 3 steps to walk the same distance for which a cat takes 4 steps. Suppose 1 step of the dog covers 1 foot. How many feet would the cat cover in taking 12 steps
According to unitary method, cat takes 12 steps to cover 9 feet.
How do you translate distance in steps?Measure your stride length or assume that it is 2.2 feet for women and 2.5 feet for men to determine it. Add the stride length to the number of steps, for example, 2.2 feet multiplied by 1,000 feet equals 2,200 feet. The answer is 2,200 ft / 5,280 0.42 mi when expressed in miles.
Given, it takes a dog three steps to cover the same distance as a cat four steps.
4 steps of a cat = 3 steps of a dog
12 cat steps equal (3/4)*12 to 9 dog steps.
Additionally, a dog's step covers one foot.
The dog moves nine feet in nine steps.
So a cat takes 12 steps to cover 9 feet.

How many glass squares will each student get? A. Write an expression that can be used to find the number of glass squares each student will receive. B. Complete the given division problem to find the number of squares each student will receive. C. How many whole glass squares will each student receive? 1,240 glass squares D. A remainder is the amount left over when an amount cannot be divided equally. What does the remainder mean in this context? 121)1240 30 R
Answer: A. To find the number of glass squares each student will receive, we need to divide the total number of squares by the number of students.
We can write this as:
x = number of glass squares per student
x = 1240 / 121
B. To find the number of squares each student will receive, we need to solve for x by dividing 1240 by 121.
1240 ÷ 121 = 10.246753246753247
C. Each student will get 10 whole glass squares.
D. The remainder in this context is the number of glass squares that cannot be distributed evenly among the students. In this case, the remainder is 30. It means that there will be 30 glass squares left over after each student has received 10 squares. It's like remainder in division where after dividing 1240 by 121 the quotient is 10 and the remainder is 30.

Find the value of p and q for which the system of equations represent coincident lines:
2x + 3y = 7
(p + q + 1)x + (p + 2q + 2)y = 4(p + q) +1
Answer: The value of p and q for which the system of equations represent coincident lines is p = 2 and q = 1.
Step-by-step explanation: To represent coincident lines, the two lines must be proportional. Therefore, the slope of the second line must be equal to the slope of the first line.
The slope of the first line is 3/2. The slope of the second line is p + 2q + 2/p + q + 1. Therefore, we set these two equal:
3/2 = p + 2q + 2/p + q + 1.
Cross multiplying, we get:
3(p + q + 1) = 2(p + 2q + 2).
Simplifying, we get:
3p + 3q + 3 = 2p + 4q + 4.
Combining like terms, we get:
p - q = 1.
Therefore, the value of p and q for which the system of equations represents coincident lines is p = 2 and q = 1.

A 20-gallon bathtub is to be filled with water that is exactly 100°F. The hot water supply is 175°F and the cold water supply is 20°F. When mixed, the temperature will be a weighted average based on the amount of each water source in the mix. How much of each should be used to fill the tub as specified?
320/31 gallons of hot water and 300/31 gallons of cold water are needed.
Here we are required to fill a 20-gallon bathtub and the water should be precisely 100° F.
It is given that hot water has a temperature of 175° F and cold water has a temperature of 20° F.
Let the amount of hot water used be x gallons.
Let the amount of cold water used be y gallons.
Since the bathtub has a capacity of 20 gallons,
x + y = 20 [1]
or, y = 20 - x [2]
The temperature after the water is mixed will be a weighted average of the temperature and amt of water used.
Hence we get,
(175x + 20y) / (x + y) = 100
from equation [1] we get
175x + 20y = 2000 [3]
from equations [2] and [3] we get
155x - 400 = 2000
or, x = 1600/155 = 320/31 [4]
Similarly,
y = 20 - 320/31
= 300/31
Hence 320/31 gallons of hot water and 300/31 gallons of cold water are needed.

Which of the following is the quotient of the rational expressions shown
below?
X/3x-1 divide x-2/2x
Answer: To divide two rational expressions, you need to first find the least common denominator (LCD) of the two expressions. The LCD is the least common multiple of the two denominators.
In this case, the rational expressions are x/(3x-1) and (x-2)/(2x). The LCD of these two expressions is (3x-1)(2x), which can be factored as 6x(x-1).
To divide the two rational expressions, you need to express each expression as a fraction with the LCD as the denominator.
The first expression, x/(3x-1), can be rewritten as (x * (2x))/(3x-1 * (2x)) = (2x^2)/(6x^2-2x).
The second expression, (x-2)/(2x), can be rewritten as ((x-2) * (3x-1))/(2x * (3x-1)) = (3x^2-3x+2)/(6x^2-2x).
To divide these two expressions, you can divide the numerators and the denominators separately:
(2x^2)/(6x^2-2x) ÷ (3x^2-3x+2)/(6x^2-2x)
= (2x^2) ÷ (3x^2-3x+2)
= (2/3)x^2 ÷ (x^2-x+2/3)
Therefore, the quotient of the rational expressions x/(3x-1) and (x-2)/(2x) is (2/3)

How do you write a compound statement in symbolic form?
A compound statement is a statement that combines two or more simpler statements using logical connectives such as "and", "or", "not", "if-then", "if and only if", etc. To write a compound statement in symbolic form, you can use logical symbols to represent the different parts of the statement.
"∧" (and) is used to connect two statements, meaning that both statements must be true for the compound statement to be true. For example, "P ∧ Q" is read as "P and Q" and represents the statement "P and Q are true."
"∨" (or) is used to connect two statements, meaning that at least one of the statements must be true for the compound statement to be true. For example, "P ∨ Q" is read as "P or Q" and represents the statement "P or Q is true."
"¬" (not) is used to negate a statement, meaning that the statement is false if the original statement is true and vice versa. For example, "¬P" is read as "not P" and represents the statement "P is false."
"→" (if-then) is used to connect two statements, meaning that if the first statement is true, then the second statement must also be true. For example, "P → Q" is read as "if P then Q" and represents the statement "if P is true, then Q is also true."
"↔" (if and only if) is used to connect two statements, meaning that the two statements are either both true or both false. For example, "P ↔ Q" is read as "P if and only if Q" and represents the statement "P is true if and only if Q is true."
For example, the compound statement "If it is raining, then I will bring an umbrella, but if it's not raining, I will wear sunglasses" can be written in symbolic form as:
(R → U) ∧ (¬R → S)
Where "R" represents the statement "it is raining", "U" represents the statement "I will bring an umbrella" and "S" represents the statement "I will wear sunglasses".

What are some rules for the transformation of functions?Suppose we have a function f(x).
f(x) ± d = Vertical upshift/downshift by d units (x, y ±d).
f(x ± c) = Horizontal left/right shift by c units (x - + c, y).
(a)f(x) = Vertical stretch for a > 0, vertical shrink a < 0. (x, ay).
f(bx) = Horizonatal compression b > 0, horizontal stretch for b < 0. (bx , y).
f(-x) = Reflection over the y-axis, (-x, y).
-f(x) = Reflection over x-axis, (x, -y).
Given, A function f(x) is transformed to f(x - 5/3) this results in f(x) is translated 5/3 units to the right along the x-axis.
And, The transformation f(x) - 5/3 is translated 5/3 units down along the y-axis.

A bicycle wheel has a diameter of 559 mm and has 32 equally spaced spokes. What is the approximate arc length, rounded to the nearest hundredth, between each spoke? Use 3. 14 for π. Show your work
The approximate arc length rounded to the nearest hundredth, between each spoke is 54.9 mm.
Diameter = 559 mm, r = d/2 = 279.5 mm
Number of spokes = 32
π = 3.14
To solve this question, we have to use the formula of the length of an arc which is given as
L = θ/360 × 2πr
To calculate the angle between each spoke, let's divide 360 by 32
θ = 360/32
θ = 11.25°
Now we have the value of the angle, substitute it and solve for the length of the arc.
[tex]L_{arc}[/tex] = θ/360 × 2πr
= 11.25/360 × 2 × 3.14 × 279.5
= 54. 9 mm
