Sharon is five years older than Robert. Five years ago, Sharon was twice as old as Robert was then. How old is Robert?

Answers

Answer 1

Robert is currently 10 years old. Given that five years ago Sharon was twice as old as Robert was then, we can set up the following equation: y + 5 = 2(y)

We are given the information that Sharon is five years older than Robert, and five years ago Sharon was twice as old as Robert was then. This means we can create a system of equations to solve for Robert's age.

Let x = Robert's current age

Let y = Robert's age five years ago

Given that Sharon is five years older than Robert, we can set up the following equation:

x + 5 = Sharon's current age

Given that five years ago Sharon was twice as old as Robert was then, we can set up the following equation:

y + 5 = 2(y)

Solving the first equation for x, we get x = Sharon's current age - 5. Substituting this into the second equation, we get:

y + 5 = 2(Sharon's current age - 5)

Solving this equation for y, we get y = (Sharon's current age - 5)/2.

Since Sharon is five years older than Robert, Sharon's current age is x + 5. Substituting this into our equation for y, we get:

y = (x + 5 - 5)/2

Simplifying this equation, we get y = x/2. This means that Robert's age five years ago was half of his current age.

Since we know that Robert is currently 10 years old, Robert's age five years ago was 5. Therefore, Robert is currently 10 years old.

If MNO IS NMO what statement best describes triangle MON?

Answers

If MNO is NMO, it means that the second and third vertices of the triangle have switched places, but the first vertex remains the same. Therefore, triangle MON is congruent to triangle NMO.

as they have the same side lengths and angles. Specifically, the sides MO, ON, and NM are congruent, and the angles at vertices M, O, and N are also congruent. We can represent this relationship between the two triangles using the symbol ≅, so we can say that triangle MON ≅ triangle NMO. The concept of congruent triangles is a fundamental principle in geometry. Two triangles are said to be congruent if their corresponding sides and angles are equal. When two triangles are congruent, we can say that they have the same size and shape, but they may be oriented differently in space. here are several ways to prove that two triangles are congruent, such as the side-angle-side (SAS), angle-side-angle (ASA), side-side-side (SSS), angle-angle-side (AAS), and hypotenuse-leg (HL) congruence criteria.

Answers

The two z-scores that separate the middle 87.4% of the distribution from the area in the tails of the standard normal distribution are -1.46 and 1.46.


To find these z-scores, we need to first determine the area in the tails of the distribution. Since the middle 87.4% of the distribution is separated from the tails, the area in the tails is 100% - 87.4% = 12.6%. This means that there is 12.6% / 2 = 6.3% in each tail.

Next, we can use a standard normal table or a calculator to find the z-scores that correspond to the 6.3% in the tails. We want to find the z-scores that have an area of 0.063 to the left and to the right of them.

According to a standard normal table, the z-score that has an area of 0.063 to the left of it is -1.46, and the z-score that has an area of 0.063 to the right of it is 1.46.

Therefore, the two z-scores that separate the middle 87.4% of the distribution from the area in the tails of the standard normal distribution are -1.46 and 1.46.

How to find the probability of A and B?

Probability is the measure of the likelihood or chance of an event occurring. It deals with the study of random events and the analysis of their outcomes.

Since A and B are mutually exclusive, they cannot happen at the same time. This means that P(A and B) = 0.

a) P(A and B) = 0

b) P(A or B) = P(A) + P(B)

P(A or B) = 0.45 + 0.45 = 0.9

c) P(notA) = 1 - P(A)

P(notA) = 1 - 0.45 = 0.55

d) P(notB) = 1 - P(B)

P(notB) = 1 - 0.45 = 0.55

e) P(not(A or B)) = 1 - P(A or B)

P(not(A or B)) = 1 - 0.9 = 0.1

Answers

Answer:

47 - 6√10

Step-by-step explanation:

Area of a square of side a = a²

Here a = √2 -3√5

Area A = a² = (√2 -3√5)²

We know that (a - b)² = a² -2ab +b²

So

A = (√2 -3√5)²

= (√2)² - 2(√2)(3√5) + (3√5)²

(√2)² = 2   because (√a)² = a

(3√5)² = 3² x (√5)² = 9 x 5 = 45

2(√2)(3√5) = 2 (√2 · 3 · √5)

= 2 x 3 √2 √5

√2√5 = √10

2 x 3 √2 √5 = 2 · 3 · √10 = 6√10

Therefore area = 2 - 6√10 + 45

Answer: f(x,y)=e^(ax+by) with a^2+b^2=1. Prove that : f''(xx)+f''(yy)=1

Answers

Proved that if the function f(x,y)=e^(ax+by) with a^2+b^2=1, then f''(xx)+f''(yy)=1

To find the second partial derivatives of f(x, y), we differentiate f(x, y) twice with respect to x and y:

f'(x, y) = ae^(ax + by) and f''(xx) = a^2e^(ax + by)

f'(x, y) = be^(ax + by) and f''(yy) = b^2e^(ax + by)

Adding these second partial derivatives, we get:

f''(xx) + f''(yy) = a^2e^(ax + by) + b^2e^(ax + by)

Since a^2 + b^2 = 1, we have:

f''(xx) + f''(yy) = e^(ax+by)

But f(x, y) = e^(ax+by), so:

f''(xx) + f''(yy) = f(x, y)

Therefore, we have proved that f''(xx) + f''(yy) = 1.

What is a triangle?

A triangle is a polygon since it possesses two or so additional components beyond that. It is plainly rectangular in form. A and B are the only two of either a triangle's three edges that can distinguish it from a typical triangle. When bounds are still not precisely collinear, Euclidean geometry yields a single region rather than a cube. Three edges and three angles are what make a triangle.

Here,

Because a triangle's angles sum up to 180 degrees, we can determine the size of angle x by deducting the other two angles from 180 degrees:

=> x = 180° - 35° - 44°

=> x = 101°

A figure on a coordinate plane is dilated using the rule (6/5x, 6/5y). Tyson says the dilation was a reduction and tashi says the dilation was an enlargement who is correct

Answers

The dilation is an enlargement, and Tashi is correct.

How to determine the dilation?

To determine whether the dilation (scaling) is a reduction or an enlargement, we need to compare the distances between corresponding points on the original figure and the dilated figure.

Suppose a point P(x,y) is on the original figure. After the dilation with the rule (6/5x, 6/5y), the corresponding point P'(x', y') will be:

P' = (6/5x, 6/5y)

The distance between point P and the origin is given by:

d(P) = √(x² + y²)

The distance between point P' and the origin is:

d(P') = √((6/5x)² + (6/5y)²)

= 6/5 * √(x² + y²)

Since the dilation multiplies each coordinate by a factor of 6/5, the distance between any point and the origin is multiplied by a factor of 6/5.

Therefore, if 6/5 < 1, then the distances between corresponding points are reduced, and the dilation is a reduction. If 6/5 > 1, then the distances are increased, and the dilation is an enlargement.

In this case, we have:

6/5 > 1

Therefore, the dilation is an enlargement, and Tashi is correct.

To find the rate of change of given functions, we have to differentiate the given function w.r.t the variable provided. We will solve each part of the question and differentiate the functions step by step.

(a) f(x) = 5x² + 3x - 7

The function is, f(x) = 5x² + 3x - 7

Differentiating the above function, we get;

f'(x) = (5x² + 3x - 7)/dx

f'(x) = 10x + 3

Therefore, the rate of change of function f(x) = 5x² + 3x - 7 is 10x + 3.

Now, let us solve the second part of the question.

Answers

From the given data, the probability of Z less than 1.56, greater than 1.56, between 1.56 and 1.81 and less than 1.56 or greater than 1.81 is 0.9406, 0.0359, 0.0235 and 0.9765 respectively.

a. From the cumulative standardized normal distribution table, we can look up the value 1.56 in the left column and find the corresponding value of 0.9406 in the intersecting row. Therefore, the probability that Z is less than 1.56 is 0.9406.

b. From the cumulative standardized normal distribution table, we can look up the value 1.81 in the left column and find the corresponding value of 0.9641 in the intersecting row. Since we want the probability that Z is greater than 1.81, we subtract this value from 1 to get 1 - 0.9641 = 0.0359 (rounded to four decimal places as needed). Therefore, the probability that Z is greater than 1.81 is 0.0359.

c. To find the probability that Z is between 1.56 and 1.81, we need to subtract the probability that Z is less than 1.56 from the probability that Z is less than 1.81. From the table, we know that the probability that Z is less than 1.56 is 0.9406 and the probability that Z is less than 1.81 is 0.9641. Therefore, the probability that Z is between 1.56 and 1.81 is 0.9641 - 0.9406 = 0.0235 (rounded to four decimal places as needed).

d. The probability that Z is less than 1.56 or greater than 1.81 is the sum of the probabilities that Z is less than 1.56 and Z is greater than 1.81, since these events are mutually exclusive. From parts (a) and (b), we know that the probability that Z is less than 1.56 is 0.9406 and the probability that Z is greater than 1.81 is 0.0359. Therefore, the probability that Z is less than 1.56 or greater than 1.81 is 0.9406 + 0.0359 = 0.9765 (rounded to four decimal places as needed).

= [sec + tan + sec - tan]/[(sec - tan)(sec + tan)]

= [2sec]/[(sec - tan)(sec + tan)]

since (a+b)(a-b) = a^2 - b^2

=> 2sec/(sec^2 - tan^2)

let's work on the denominator (sec^2 - tan^2)

we know sec = 1/cos and tan = sin/cos

=> (1/cos)^2 - (sin/cos)^2

=> 1/cos^2 - sin^2/cos^2

=> (1 - sin^2)/cos^2 = cos^2/cos^2 = 1

so 2sec/(sec^2 - tan^2) => 2sec/1

=> 2sec

since sec = 1/cos => 2sec = 2(1/cos) = 2/cos

Right side

1/cos + 1/cos = 2/cos

Answers

The height of the cone is 11 mm and the slant height of the cone is 23 mm and the ant crawls 31 mm to get from the base of the cone to the top of the hill.

What is the volume of the right circular cone?

A right circular cone is a three-dimensional geometric shape that has a circular base and a vertex that is located directly above the center of the base. The axis of the cone is a line that passes through the vertex and the center of the base.

The volume of a right circular cone can be found using the formula:

[tex]V = (1/3)\pi r^2h[/tex]

where V is the volume of the cone, r is the radius of the circular base, and h is the height of the cone.

1) To find the height of the cone, we need to use the formula for the volume of a cone, which is [tex]V = (1/3)\pi r^2h[/tex]. Rearranging this formula, we get:

[tex]h = 3V / \pi r^2[/tex]

Substituting the given values, we get:

[tex]h = 3(8792) / (3.14)(20^2)[/tex]

h ≈ 11

Therefore, the height of the cone is approximately 11 mm.

2) To find the slant height of the cone, we can use the Pythagorean theorem, which states that in a right triangle, the square of the hypotenuse (the longest side) is equal to the sum of the squares of the other two sides.

In the case of the cone, the slant height is the hypotenuse of a right triangle formed by the height and the radius of the base. Therefore, we have:

[tex]s^2 = r^2 + h^2[/tex]

Substituting the values we found in part 1, we get:

[tex]s^2 = 20^2 + 11^2[/tex]

s ≈ 23

Therefore, the slant height of the cone is approximately 23 mm.

3) To find the distance the ant crawls to get from the base of the cone to the top of the hill, we can use the Pythagorean theorem again. This time, we need to find the distance along the slant height from the base of the cone to the top of the hill. This distance is the hypotenuse of a right triangle formed by the distance from the base to the apex (which is the height of the cone) and the radius of the base. Therefore, we have:

[tex]d^2 = r^2 + s^2[/tex]

Substituting the values we found in parts 1 and 2, we get:

[tex]d^2 = 20^2 + 23^2[/tex]

d ≈ 31

Therefore, the ant crawls approximately 31 mm to get from the base of the cone to the top of the hill.

4) Hamid purchased some educational stationary and paid GST of Rs.1800. He sold all
educational stationary Nishaben and collected GST of Rs.2100. Find the GST CGST and
SGST to be paid

Answers

Answer: Therefore, Hamid needs to pay Rs. 1050 as both CGST and SGST.

Step-by-step explanation:

Assuming the GST rate is the same for both the purchase and the sale, we can calculate the GST rate as follows:

GST rate = GST paid / Cost of stationary purchased

= 1800 / Cost of stationary purchased

Since we don't have the cost of stationary purchased, we can't calculate the GST rate or the CGST and SGST amounts directly. However, we know that the GST collected from Nishaben was Rs. 2100, which is equal to the GST paid plus the profit earned on the sale. We can express this mathematically as follows:

GST collected = GST paid + Profit

Profit = GST collected - GST paid

= 2100 - 1800

= Rs. 300

Since the profit earned is Rs. 300, we can find the cost of the stationary purchased by subtracting the profit from the amount collected from Nishaben:

Cost of stationary purchased = GST collected - Profit

= 2100 - 300

= Rs. 1800

Now that we know the cost of the stationary purchased, we can calculate the GST rate as follows:

GST rate = GST paid / Cost of stationary purchased

= 1800 / 1800

= 1

Since the GST rate is 1 (or 100%), we can divide the total GST collected equally between CGST and SGST:

CGST = SGST = GST collected / 2

= 2100 / 2

= Rs. 1050

Therefore, Hamid needs to pay Rs. 1050 as both CGST and SGST.

Read the passage from Animal Farm.Presently the tumult died down. The four pigs waited, trembling, with guilt written on every line of their countenances. Napoleon now called upon them to confess their crimes. They were the same four pigs as had protested when Napoleon abolished the Sunday Meetings. Without any further prompting they confessed that they had been secretly in touch with Snowball ever since his expulsion, that they had collaborated with him in destroying the windmill, and that they had entered into an agreement with him to hand over Animal Farm to Mr. Frederick. They added that Snowball had privately admitted to them that he had been Jones's secret agent for years past. When they had finished their confession, the dogs promptly tore their throats out, and in a terrible voice Napoleon demanded whether any other animal had anything to confess.The three hens who had been the ringleaders in the attempted rebellion over the eggs now came forward and stated that Snowball had appeared to them in a dream and incited them to disobey Napoleon's orders. They, too, were slaughtered. Then a goose came forward and confessed to having secreted six ears of corn during the last year's harvest and eaten them in the night. Then a sheep confessed to having urinated in the drinking poolurged to do this, so she said, by Snowballand two other sheep confessed to having murdered an old ram, an especially devoted follower of Napoleon, by chasing him round and round a bonfire when he was suffering from a cough. They were all slain on the spot. And so the tale of confessions and executions went on, until there was a pile of corpses lying before Napoleon's feet and the air was heavy with the smell of blood, which had been unknown there since the expulsion of Jones.How does Napoleons questioning of the pigs demonstrate the authors purpose of reflecting reality?It shows similarities with Stalin's Great Purge and reveals how dictators use fear to control people.It shows how some animals are capable of using nonviolent tactics to gain power over others.It shows how leaders blame others for the problems of the society they lead and punish them accordingly.It shows how both Napoleon and Stalin used promises of a better life to take control of a group.
