if A shopkeeper sold a Radio at 336 rs and gain 5 persent profit find c. p
Answer:
If the shopkeeper sold the radio for 336 rs and gained a 5% profit, then the cost price (c.p.) of the radio can be calculated as follows:
Let x be the cost price of the radio. Since the shopkeeper gained a 5% profit, we can write the equation: x + 0.05x = 336 Solving for x, we get: x(1 + 0.05) = 336 x = 336/1.05 x = 320
So, the cost price (c.p.) of the radio is 320 rs.

An object 60m long is drawn using a scale of 1cm to 10m. What is the length on drawing?
Using strategy 1 (in your head), divide 60m by 10m to get 6, then multiply that number by one to get 6cm. the length on drawing is 6cm
Procedure 2 (proportions)
Create a proportion first.
We know that 1 cm equals 10 metres, so we place them on a fraction (the operation is unaffected by the denominator or numerator). However, we don't know how many cm equal 10m, so we make that into a variable, in this case x.
1cm x cm
——— ———
100m 60m
Go diagonally to where the variables have already been put in to solve a proportion. You are unable to calculate 60 metres and x centimetres because you are unsure of x. Yet you can travel 60m. Start by multiplying 1 by 30 to reach the number 60. The result of multiplying 60 by 10m is x. This will equal 6.
Thus, your response is 6.

. a model for the population p(t) in a suburb of a large city is given by the initial-value problem dp dt 5 p(1021 2 1027 p), p(0) 5 5000, where t is measured in months. what is the limiting value of the population? at what time will the population be equal to onehalf of this limiting value?
The population will be equal to one-half of the limiting value after 4.67 months.
Model for the population p(t) in a suburb of a large city is given by the initial-value problem dp/dt= 5 p(1021−2×1027p), p(0) = 5000. Now we are to find out the limiting value of the population and the time when the population will be equal to one-half of the limiting value.Limiting value of the populationThe limiting value is the population value when the population grows until it levels off. In other words, we can say that it is the maximum population that can be sustained by the resources available.
We can find the limiting value by considering what would happen if the rate of change of the population became zero. This can occur only when p=0 or 1021−2×1027p =0.Solving this equation, we get p = 0 and p = 5.1 × 10⁷/2 = 2.55 × 10⁷Thus, the limiting value of the population is 2.55 × 10⁷.We know that the population is given by p(t) and we have to find the time when the population will be equal to one-half of the limiting value. To find t, we need to solve the differential equation dp/dt= 5 p(1021−2×1027p).
Separating variables, we getdp/p(1021−2×1027p) = 5 dtOn integrating, we get-1/2 ln|1021−2×1027p| = 5t + CWhere C is the constant of integration.Using the initial condition p(0) = 5000, we getC = -1/2 ln|1021−2×1027(5000)|Solving for C, we getC ≈ -2.97Solving for p, we get1021−2×1027p = ±e^(-10t+2.97)Multiplying both sides by -1/2, we get-0.5(1021−2×1027p) = ±0.5e^(-10t+2.97)Taking the negative sign, we getp = 0.5(1021 + 0.5e^(-10t+2.97))/1027Substituting p = 1.275 × 10⁷, we get1.275 × 10⁷ = 0.5(1021 + 0.5e^(-10t+2.97))/1027Multiplying both sides by 1027 and simplifying, we get1.32 × 10^4 = 1021 + 0.5e^(-10t+2.97)Solving for e^(-10t+2.97), we gete^(-10t+2.97) = 2 × (1.32 × 10^4 - 1021)Taking the natural logarithm, we get-10t + 2.97 = ln[2 × (1.32 × 10^4 - 1021)]Solving for t, we gett ≈ 4.67 months.

what enone product would you expect to obtain from intramolecular aldol condensation of 3-methylheptane dial?
The expected product from the intramolecular aldol condensation of 3-methylheptane dial is a cyclic α,β-unsaturated ketone with a seven-membered ring.
3-methylheptane dial is a 7-carbon compound with two carbonyl groups, one at each end of the molecule. Intramolecular aldol condensation occurs when one carbonyl group reacts with the other within the same molecule. The carbonyl group acts as an electrophile, while the enolate formed from the other carbonyl group acts as a nucleophile.
In the case of 3-methylheptane dial, intramolecular aldol condensation can occur between the carbonyl group at the 3-position and the enolate formed from the carbonyl group at the 6-position. The resulting intermediate undergoes dehydration to form a cyclic α,β-unsaturated ketone.
The product of the reaction will have a cyclic structure with a double bond between the α and β carbons. The exact structure of the product will depend on the stereochemistry of the starting material and the reaction conditions. However, the product is expected to have a seven-membered ring and to be an α,β-unsaturated ketone.
Therefore, the expected product from the intramolecular aldol condensation of 3-methylheptane dial is a cyclic α,β-unsaturated ketone with a seven-membered ring.

A rope is swinging in such a way that the length of the arc is decreasing geometrically. If the the first arc is 18 feet long and the third arc is 8 feet long, what is the length of the second arc?
Explain step by step.
Geometric Sequence:
In mathematics, a sequence in which each number is multiplied by its previous term is called a geometric sequence.
The standard form of the geometric sequence is:
an=a1×rn−1Where, r = Common ratio a1= First term an=n th term
The length of the second arc is 8 feet.
The rope is swinging in such a way that the length of the arc is decreasing geometrically.
If the first arc is 18 feet long and the third arc is 8 feet long,
The length of the second arc :
In order to find the second arc length, we need to use the formula of the geometric sequence.
We have to understand what is given and what is required.
Given : First arc = 18 feet
Third arc = 8 feet.
To Find : Length of the second arc.
The formula of the geometric sequence is :
[tex]a_n[/tex] = [tex]a_1[/tex] × rn − 1
where, r = Common ratio [tex]a_1[/tex] = First term [tex]a_n[/tex] = [tex]n^{th}[/tex] term
Here, the length of the first arc is [tex]a_1[/tex] = 18.
The length of the third arc is [tex]a_3[/tex] = 8.
We have to find the length of the second arc, which is [tex]a_2[/tex]
Using the formula of the geometric sequence, we can find the [tex]a_1[/tex]: r= [tex]a_3[/tex] / [tex]a_2[/tex]
We know that [tex]a_1[/tex]= 18 and [tex]a_3[/tex]= 8
Substitute the values: r= 8 / [tex]a_2[/tex]
Now, we can rewrite the formula of the geometric sequence: an=[tex]a_1[/tex]×rn−1an= [tex]a_1[/tex] x r(n-1)
The length of the first arc is [tex]a_1[/tex] = 18 feet.
Substituting the value of r, we get:
8 / [tex]a_2[/tex] = r18 x r(n-1) = [tex]a_2[/tex]
We are given that the length of the third arc is 8 feet,
thus : 8 = 18 x r(3-1)8
= 18 x [tex]r_2[/tex][tex]r_2[/tex]
= 8 / 18[tex]r_2[/tex]
= 4 / 9r
= √(4/9)
Using this value of r, we can find the length of the second arc :
[tex]a_2[/tex] = 18 x (4/9) (2-1) [tex]a_2[/tex]
= 18 x (4/9)[tex]a_2[/tex]

(a) The distance that the tip of the hour hand covers in twelve hours is 28.29 cm.
(b)The distance that the tip of the minute hand covers in one hour is 34.57 cm.
(c) The tip of the minute hand covers a longer distance than the tip of the hour hand by 6.28 cm.
How to find the distance the tip of the hour hand cover in twelve hours?(a) To find the distance that the tip of the hour hand covers in twelve hours, we need to calculate the circumference of the circle that the tip of the hour hand traces in twelve hours. The circumference is given by:
C = 2πr
where r is the length of the hour hand
C = 2 x 22/7 x 4.5
C = 28.29 cm
(b) Also, the distance that the tip of the minute hand covers in one hour is:
C = 2 x 22/7 x 5.5
C = 34.57 cm
(c) We can see that the distance covered by the minute hand in one hour (34.57 cm) is greater than the distance covered by the hour hand in twelve hours (28.29 cm).
difference = 34.57 cm - 28.29 cm = 6.28 cm
Thus, the tip of the minute hand covers a longer distance than the tip of the hour hand by 6.28 cm.

The value of the function q and r are as follows (q ° r )(7) = 22 and (r ° q)(7) = 8.
What are composite functions?The process of integrating two or more functions into one function is known as composition of functions. A function is an example of labour. Take making bread as an example. Let x be the flour, let g(x) be the function that the food processor performs to prepare the dough using the flour, and let f(x) be the function that the oven does to bake the bread. The output of g(x) should be sent into the function f(x) to make bread (i.e., the prepared dough should be placed in the oven). The outcome is represented by the symbol f(g(x)), and it is made up of the functions f(x) and g. (x).
The function q and r are as follows:
q(x) = x² + 6
r(x) = √(x + 9)
The value of:
(q ° r )(x) = q(r(x))
Here, substitute the value of x in q(x) with the value of r(x):
q(r(x)) = (√(x + 9))² + 6
q(r(x)) = x + 9 + 6
Substitute x = 7:
q(r(7)) = 7 + 9 + 6 = 22
Now, (r ° q) = r(q(x))
r(q(x)) = √(x² + 6 + 9)
= √(x² + 15)
Substitute x = 7:
r(q(7)) = √(7² + 15) = √(49 + 15) = √64 = 8

the relationship between the diameter of the pizza and its cost per square inch is non-proportional.
The relationship between the diameter of the pizza and its cost per square inch is non-proportional.
If the relationship were proportional, then the cost per square inch of the pizza would remain constant as the diameter changes. However, in this case, we see that as the diameter of the pizza increases, the cost per square inch decreases. This is because the area of a circle increases more rapidly than its diameter, so the cost must be spread out over a larger area, resulting in a lower cost per square inch.
Therefore, the relationship between the diameter of the pizza and its cost per square inch is non-proportional.

The coordinates of the graph when reflected over x-axis is given as A' (7, -8) and B' (2, -3).
What are transformations?The transformation, or f: X X, is the name given to a function, f, that maps to itself. After the transformation, the pre-image X becomes the picture X. Any operation, or a combination of operations, such as translation, rotation, reflection, and dilation, can be used in this transformation. A function can be moved in one way or another using translation, rotation, reflection, and dilation. A function can also be scaled using rotation around a point. Two-dimensional mathematical figures move about a coordinate plane according to transformations.
The mapping of reflection over the x-axis is depicted as follows:
(x, y) to (x, -y)
The coordinates of A and B are:
A (7, 8)
B (2, 3)
After the reflection over x-axis the coordinates are transformed as follows:
A' = (7, -8)
B' = (2, -3)
Hence, the coordinates of the graph when reflected over x-axis is given as A' (7, -8) and B' (2, -3).

A banner is centered between two poles by four ropes of equal length. The dimensions of the banner ground and poles are shown what is the length of one of the ropes x to the nearest foot
The length of one of the ropes is approximately 10.77 feet when rounded to the nearest foot.
Let's call the distance between the poles "d" and the height of the poles "h". We can use the Pythagorean theorem to find the length of the ropes:
If we draw a diagram, we can see that the four ropes form the hypotenuses of four right triangles. Each right triangle has a base of d/2 and a height of h - (banner height)/2.
Therefore, we have:
[tex]x^2[/tex] = [tex](d/2)^2[/tex] + [tex](h - (banner height)/2)^2[/tex]
Substituting the given values, we get:
[tex]x^{2}[/tex] = [tex](20/2)^2[/tex]+ [tex](16 - (8/2))/2)^2[/tex]
[tex]x^{2}[/tex]= 100 + [tex](8/2)^2[/tex]
[tex]x^{2}[/tex] = 100 + 16
[tex]x^{2}[/tex] = 116
Taking the square root of both sides, we get:
x = [tex]\sqrt{116}[/tex]
x ≈ 10.77
Therefore, the length of one of the ropes is approximately 10.77 feet when rounded to the nearest foot.

The two shorter sides of an right triangle measure 15 inches and 3 feet. What is the length of the longest side?
The two shorter sides of a right triangle measure 15 inches and 3 feet and the length of the longest side also known as the hypotenuse is 3.269557 feet.
It is given to us that the two shorter sides of a right triangle measure 15 inches and 3 feet.
Let us say that side a is 3 feet and side b is 15 inches and we need to find side c, that is the longest side also known as the hypotenuse,
A right-angled triangle is one in which only one angle is precisely 90 degrees. Since the total of all the angles in a triangle is always 180°, the other two angles will be obviously smaller than the right angle.
We define the sides of a right-angled triangle in a unique manner. The hypotenuse of a triangle is the edge that faces the right angle and is always the largest.
Pythagorean formula. Pythagoras' theorem says that: a² + b² = c². in a right triangle with cathetus a and b and with hypotenuse c.
Take the square root of both sides to find c = √(b²+a²). This Pythagorean theorem expansion can be thought of as a "hypotenuse formula."
Therefore, with this formula we can solve for hypotenuse:
side a = 15 inches = 1.3 feet
side b = 3 feet
a² + b² = c²
1.3² + 3² = c²
1.69 + 9 = c²
10.69 = c²
c = 3.269557 feet
Therefore, we can say that the two shorter sides of a right triangle measure 15 inches and 3 feet and the length of the longest side also known as the hypotenuse is 3.269557 feet.

Bo and Erica are yoga instructors. Between the two of them, they teach 43 yoga classes each week. If Erica teaches 11 fewer than twice as many as Bo, how many classes does each instructor teach per week?
Answer:
Erica teaches 32.33 or 32 classes
Bo teaches 10.67 or 10 classes
Step-by-step explanation:
B + E = 43
E - 11 = 2B
B + E = 43
E = 43 - B
E - 11 = 2B
(43 - B) - 11 = 2B
B = 10.67 = 10
B + E = 43
(10.67) + E = 43
E = 32.33 = 32
