The percentage of full marks was obtained by D is (d) 60%.

What is percentage  ?

Let's start by using the given information to find out how many marks B, C, and D got in the exam.

We know that A got 10% less than B, so if A got 360 marks, then B got 10% more than that, which is:

B = 360 + 10% of 360

= 360 + 36

= 396

We also know that B got 25% more than C, so if B got 396 marks, then C got 25% less than that, which is:

C = 396 - 25% of 396

= 396 - 99

= 297

Finally, we know that C got 20% less than D, so if C got 297 marks, then D got 20% more than that, which is:

D = 297 + 20% of 297

= 297 + 59.4

= 356.4

So D got 356.4 marks out of 500. To find out what percentage of full marks D obtained, we can use the formula:

percentage = (marks obtained / full marks) x 100

Therefore, the percentage of full marks obtained by D is:

percentage = (356.4 / 500) x 100

= 71.28%

Rounded to the nearest integer, the answer is approximately 71%, which is closest to option (d) 60%. Therefore, the answer is (d) 60%.

In other words, similar triangles have the same shape but may or may not be the same size. The triangles are congruent if their corresponding sides are also of identical length.

Corresponding sides of similar triangles are in the same ratio. The ratio of area of similar triangles is the same as the ratio of the square of any pair of their corresponding sides

Given data ,

Let the triangles be represented as ABC and CDE

Now , the triangles ABC and CDE are similar

Let the height of the statue be = measure of AB = x

Now , the height of Patty = measure of CE = 1.6 m

Let the distance between Patty and mirror be CE = 2.4 m

Let the distance between mirror and base of statue BC = 4 m

And , corresponding sides of similar triangles are in the same ratio

Therefore, the probability that a truck drives between 92 and 144 miles in a day is 0.7454, or about 74.54% (rounded to four decimal places).

Probability is a measure of the likelihood of an event occurring, expressed as a number between 0 and 1. An event with probability 0 is impossible, while an event with probability 1 is certain. In probability theory, an event is any outcome or set of outcomes of a random process or experiment. The probability of an event is determined by calculating the ratio of the number of ways the event can occur to the total number of possible outcomes. Probability is used in a wide variety of fields, including mathematics, statistics, physics, engineering, finance, and economics, to model and analyze random phenomena and make predictions about future events.

Here,

To solve this problem, we need to standardize the given values using the formula:

z = (x - μ) / σ

where z is the standard normal random variable, x is the observed value, μ is the mean, and σ is the standard deviation.

For x = 92:

z = (92 - 110) / 25 = -0.72

For x = 144:

z = (144 - 110) / 25 = 1.36

Using a standard normal distribution table or a calculator, we can find the probability that a standard normal random variable falls between -0.72 and 1.36:

If the tens digit of a two-digit number is one more than the units digit and the number itself is 6 times the sum of the digits, then the solution is a two-digit number 54.

Let's assume that the units digit of the two-digit number is x. According to the problem statement, the tens digit is one more than the units digit, which means that the tens digit is x + 1. Therefore, the two-digit number can be expressed as 10(x+1) + x, which simplifies to 11x + 10.

The problem also states that the number is 6 times the sum of its digits. The sum of the digits is x + (x + 1) = 2x + 1. Therefore, we can set up an equation:

11x + 10 = 6(2x + 1)

Simplifying the equation, we get:

11x + 10 = 12x + 6

Subtracting 11x from both sides, we get:

10 = x + 6

Subtracting 6 from both sides, we get:

x = 4

Therefore, the units digit is 4, and the tens digit is one more than that, which is 5. The two-digit number is 54. We can check that this is indeed 6 times the sum of its digits:

54 = 6(4 + 5)

The base of the triangle is 9 inches and the height is 2 inches.

Let's denote the height of the triangle as h, and the base as b.

We know that the area of a triangle is given by the formula:

Area = (1/2) * base * height

Substituting the values we have:

9 = (1/2) * b * h

Multiplying both sides by 2 gives:

18 = b * h

We also know that the base is 5 inches more than 2 times the height:

b = 2h + 5

Substituting this expression for b in terms of h in the area equation, we get:

18 = (2h + 5) * h

Expanding the right-hand side, we get:

18 = 2h^2 + 5h

Rearranging this equation, we get:

2h² + 5h - 18 = 0

We can solve for h by using the quadratic formula:

h = [-b ± [tex]\sqrt{b² - 4ac}[/tex]] / 2a

where a = 2, b = 5, and c = -18.

Plugging these values into the formula, we get:

h = [-5 ± [tex]\sqrt{5^{2} - 4(2)(-18) }[/tex]] / (2 * 2)

Simplifying:

h = [-5 ± [tex]\sqrt{169}[/tex]] / 4

Taking the positive solution:

h = [-5 + 13] / 4

h = 2

Now that we know the height is 2 inches, we can use the equation b = 2h + 5 to find the base:

b = 2(2) + 5 = 9

The situation cannot be modeled by a linear equation. The processing fee is $42 and the daily fee is $102.With a budget of $1200maximum number of days you can rent the beach house is 6 days

a. To determine if the situation can be modeled by a linear equation, we can plot the data on a graph with days on the x-axis and total cost on the y-axis.

When we plot the data, we can see that it does not form a straight line, which means the situation cannot be modeled by a linear equation.

b. To find the processing fee and the daily fee, we can use the information given in the table.

Let's call the processing fee "p" and the daily fee "d". We can set up two equations to represent the total cost for two different numbers of days:

2d + p = 246

4d + p = 450

Subtracting the first equation from the second, we get:

2d = 204

So, d = 102.

Substituting d = 102 into the first equation, we get:

2(102) + p = 246

Solving for p, we get:

p = 42

Therefore, the processing fee is $42 and the daily fee is $102.

c. We can use the equation for the total cost with the processing fee and daily fee we found in part (b) to determine the maximum number of days we can rent the beach house for $1200.

8d + p = 858

Substituting p = 42 and d = 102, we get:

8(102) + 42 = 858

Simplifying, we get:

840 + 42 = 882

So, we can rent the beach house for a maximum of 6 days with a budget of $1200

The maximum error in using the value of the radius to compute the volume of the sphere is approximately 554.86 cubic centimeters.

What is sphere ?

A sphere is a three-dimensional shape that is perfectly round, with all points on the surface at an equal distance from the center.

The formula for the volume of a sphere is given by V = (4/3)πr³, where r is the radius of the sphere.

The maximum error in the measurement of the radius is given as 0.03 cm. Therefore, the actual radius of the sphere can be anywhere between 20.97 cm (21 - 0.03) and 21.03 cm (21 + 0.03).

To find the maximum error in using this value of the radius to compute the volume of the sphere, we need to find the maximum possible difference in the volumes calculated using these two values.

So, we can calculate the volume of the sphere using the maximum and minimum values of the radius as follows:

V_max = (4/3)π(21.03)³

V_min = (4/3)π(20.97)³

Now, we can find the difference between these two values to get the maximum possible error:

Max error = V_max - V_min

Max error = (4/3)π(21.03)³ - (4/3)π(20.97)³

Max error ≈ 554.86 cubic centimeters

Therefore, the maximum error in using the value of the radius to compute the volume of the sphere is approximately 554.86 cubic centimeters.
