Converting time from the 12-hour clock format to the 24-hour clock format, and vice versa, can be a bit confusing at times, but it's not that difficult once you know how to do it.

To convert from the 12-hour clock format to the 24-hour clock format, simply add 12 hours to any time after 12:00 p.m. For example, if it's 3:00 p.m., you add 12 hours to get 15:00 (3:00 p.m. in 24-hour format). If it's 11:00 p.m., you add 12 hours to get 23:00 (11:00 p.m. in 24-hour format).

Conversely, to convert from the 24-hour clock format to the 12-hour clock format, simply subtract 12 hours from any time after 12:00 p.m. For example, if it's 16:00 (4:00 p.m.) in 24-hour format, you subtract 12 hours to get 4:00 a.m. in the 12-hour format. If it's 22:00 (10:00 p.m.) in 24-hour format, you subtract 12 hours to get 10:00 a.m. in the 12-hour format.

To help you with these conversions, here is a table with some examples:

To solve an equation, you need to isolate the variable on one side of the equation, typically the left side, and simplify the other side until you are left with an expression that has only the variable you are trying to solve for.

Here are the general steps to solve an equation:

Start by simplifying both sides of the equation as much as possible. This may involve distributing or combining like terms.

Get all terms with the variable you are solving for on one side of the equation. To do this, you can add or subtract terms from both sides of the equation. For example, if you have the equation 2x + 5 = 9, you can subtract 5 from both sides to get 2x = 4.

Isolate the variable by dividing both sides of the equation by its coefficient. In the above example, you can divide both sides by 2 to get x = 2.

Check your solution by plugging it back into the original equation and verifying that both sides of the equation are equal.

If George's bicycle has a mass of 15 grams, then it is highly unlikely that he has stated the correct mass, as 15 grams is an extremely low mass for a bicycle.

A typical bicycle weighs anywhere from 7 to 15 kilograms. It is highly unlikely that a bicycle would weigh only 15 grams, as this is much lighter than the lightest bicycle ever made.

Therefore, it is reasonable to assume that George made a mistake and meant to say 15 kilograms instead of grams.

Assuming the mass of the bicycle is 15 kilograms, removing the front wheel will decrease the mass slightly, but not by a significant amount.

The front wheel typically accounts for around 1-2 kilograms of the total mass of the bicycle, so removing it would leave a mass of approximately 14 kilograms.

However, assuming he made a mistake and meant to say 15 kilograms, then the mass of the bicycle without the front wheel would be approximately 14 kilograms.

It is also possible that there may not be a clear relationship between the two variables or that there may be other factors that influence the number of coats sold, such as seasonal trends or fashion trends.

In mathematics, a variable is a symbol or letter that represents a quantity that can vary or take on different values in a given situation or equation. Variables are commonly denoted by letters such as x, y, z, a, b, c, etc. They are used to represent unknown or changing quantities in mathematical expressions or equations.

For example, in the equation y = 2x + 3, x and y are variables. x represents an unknown value, while y represents the value that results from the equation for a particular value of x. In this case, the variable x can take on different values, and the corresponding value of y will change accordingly.

Variables are used in a wide range of mathematical concepts, such as algebra, calculus, and statistics, to represent and manipulate different quantities and relationships between them.

It is reasonable to expect that there is a negative correlation between the number of coats sold and the outside temperature. In other words, as the temperature gets colder, the number of coats sold would increase, and as the temperature gets warmer, the number of coats sold would decrease. This is because colder temperatures would typically prompt people to buy more coats to stay warm, while warmer temperatures would make people less likely to buy coats.

Answer:

Step-by-step explanation:

When visualizing how two angles are related, try squashing the two parallel lines into each other. When you do that with these angles, they go from appearing like =\= to appearing like -\-, with x and y being catty-corner from each other.

Because the parallel lines are straight, x and y are both half of a pair that adds up to 180. However, x and y aren't sharing a straight line, so they cannot add up to 180 with each other. That leaves only one possibility, that x and y have the same angle measure.

The ratio of the perimeters is 14/5, which simplifies to 70/25, which reduces to 14/5. So the answer is (d) 5/7.

Let's use the fact that the ratio of the areas of two similar triangles is equal to the square of the ratio of their corresponding side lengths. If we let the corresponding side lengths be a and b, then we have:

(area of first triangle)/(area of second triangle) = (a^2)/(b^2)

We are given that the areas of the two triangles are 50 cm^2 and 98 cm^2, respectively. Let's call the side lengths of the first triangle a1, a2, and a3, and the side lengths of the second triangle b1, b2, and b3. Then we have:

(50)/(98) = (a1a2)/(b1b2)

We don't know the actual values of a1, a2, b1, and b2, but we can find the ratio of their perimeters by adding up the side lengths of each triangle. Let's call the perimeters of the first and second triangles P1 and P2, respectively. Then we have:

P1 = a1 + a2 + a3

P2 = b1 + b2 + b3

Dividing P1 by P2, we get:

P1/P2 = (a1 + a2 + a3)/(b1 + b2 + b3)

We can rewrite the ratios of the side lengths using the equation we found earlier:

P1/P2 = [(a1a2)/(b1b2)]*[(a1 + a2 + a3)/(a1 + a2 + a3)]

P1/P2 = [(a1a2)/(b1b2)]*1

P1/P2 = (a1a2)/(b1b2)

We still don't know the values of a1, a2, b1, and b2, but we can eliminate them by using the equation we found earlier:

(50)/(98) = (a1a2)/(b1b2)

Simplifying this expression, we get:

(a1/a2) = sqrt((98/50)*(b1/b2))

We can use this to substitute for one of the ratios of side lengths in the equation for P1/P2:

P1/P2 = [(a1a2)/(b1b2)]*[(a1 + a2 + a3)/(a1 + a2 + a3)]

P1/P2 = [sqrt((98/50)(b1/b2))][(a1 + a2 + a3)/(a1 + a2 + a3)]

P1/P2 = sqrt((98/50)*(b1/b2))

Now we can substitute the given values to get:

P1/P2 = sqrt((98/50)(b1/b2)) = sqrt((98/50)(2/1)) = sqrt(196/50) = 14/5

To find the equation of the plane passing through the three points P, Q, and R, we need to first find two vectors in the plane. We can do this by subtracting P from Q and R to get:

Q - P = (3-1, 12-7, 12-4) = (2, 5, 8)
R - P = (8-1, 11-7, 7-4) = (7, 4, 3)

Next, we can take the cross product of these two vectors to get a vector that is perpendicular to the plane:

(2, 5, 8) x (7, 4, 3) = (-29, 50, -23)

Now we have the equation of the plane in the form ax + by + cz = d, where (a, b, c) is the normal vector we just found and (x, y, z) is any point on the plane (we can use one of the three given points):

Answer:

70 dogs

Step-by-step explanation:

sum the parts of the ratio , 5 + 2 = 7 parts

divide total by 7 to find the value of one part of the ratio

98 ÷ 7 = 14 ← value of 1 part of the ratio , then

5 × 14 = 70 ← number of dogs

In the circle, the measure of p is 34 (option 3).

First, we know that angle MBC is an exterior angle to triangle PBC. Therefore, the measure of angle PBC is equal to the sum of angles MBC and MCB, which is 100 + (1/2)(angle MCP) = 100 + (1/2)(angle MQP).

Similarly, angle MCD is an exterior angle to triangle PCD. Therefore, the measure of angle PDC is equal to the sum of angles MCD and MDC, which is 62 + (1/2)(angle MPQ) = 62 + (1/2)(angle MQP).

Since angle PBC and angle PDC are both subtended by the same arc BC, they are equal. Therefore, we can set the expressions for these angles equal to each other and solve for angle MQP:

100 + (1/2)(angle MQP) = 62 + (1/2)(angle MQP)

38 = (1/2)(angle MQP)

angle MQP = 76 degrees

Finally, we can use the fact that angles MPQ and MQP form a linear pair, so they add up to 180 degrees. Therefore, angle MPQ is 180 - 76 = 104 degrees.

Since angle MPQ is an exterior angle to triangle PAB, we can use the exterior angle theorem to find the measure of angle P, as follows:

angle P = angle MPQ + angle PAB = 104 + 100 = 204 degrees

However, angles in a circle cannot be greater than 180 degrees, so we need to subtract 180 from angle P to get the actual measure of angle P:

angle P = 214 - 180 = 34 degrees

Therefore, the answer is option (3).

c. The change in revenue due to the change in price is GHS 20,000

a. The price elasticity of demand is given by the formula:

Price elasticity of demand = (Percentage change in quantity demanded) / (Percentage change in price)

The percentage change in quantity demanded is (6000 - 4000) / 4000 * 100% = 50%

The percentage change in price is (30 - 40) / 40 * 100% = -20%

Therefore, the price elasticity of demand = 50% / (-20%) = -2.5

b. Since the price elasticity of demand is greater than 1,-2.5. This means that the percentage change in quantity demanded is greater than the percentage change in price.

c. The revenue is given by the formula:

Revenue = Price x Quantity

At a price of GHS 40, the revenue is 4000 x 40 = GHS 160,000

At a price of GHS 30, the revenue is 6000 x 30 = GHS 180,000

Therefore, the change in revenue is GHS 20,000, which is an increase of 12.5%.

The final temperature after the next 8 hours (6 hours at -0.8°C per hour, followed by 2 hours at -0.8°C per hour) will be -2.4°C.

The final temperature can be calculated by subtracting the total temperature change from the initial temperature of 4°C.

The total temperature change during the next six hours can be calculated by multiplying the mean rate of -0.8°C per hour by the number of hours, which is 6.

-0.8°C/hour x 6 hours = -4.8°C

Therefore, the temperature after the next six hours will be:

4°C - 4.8°C = -0.8°C

For the next two hours, the temperature changed at a mean rate of -0.8°C per hour. This means the temperature decreased by:

-0.8°C/hour x 2 hours = -1.6°C

So the final temperature will be:

-0.8°C - 1.6°C = -2.4°C.

Therefore, the final temperature after the next 8 hours (6 hours at -0.8°C per hour, followed by 2 hours at -0.8°C per hour) will be -2.4°C.

The maximal area of a right triangle with hypotenuse of length 3 is 0.

Let's call the legs of the right triangle a and b.

Since the hypotenuse has length 3, we know that a² + b² = 3² = 9

The area of the triangle is given by A = 1/2 ab.

We want to maximize A subject to the constraint a² + b²= 9.

One way to do this is to use the method of Lagrange multipliers.

We want to maximize the function f(a, b) = 1/2 ab subject to the constraint g(a, b) = a²+ b² - 9= 0. The Lagrangian is then:

L(a, b, λ) = f(a, b) - λg(a, b) = 1/2 ab - λ(a² + b² - 9)

To find the maximum, we need to solve the system of equations:

Taking the partial derivatives and setting them equal to zero, we get:

Solving the first two equations for a and b in terms of λ and plugging them into the third equation,

we get:

4λ² + 1 = 0

Then from the constraint a² + b² = 9, we have a = ±3.

The area of the triangle in this case is A = 1/2 ab = 0.

Therefore, the maximal area of a right triangle with hypotenuse of length 3 is 0, and it is achieved when one of the legs has length 0.

The expression |y-x| without absolute value is simply: y-x

In mathematics, the absolute value refers to the magnitude or numerical value of a real number without considering its sign. It gives the distance of the number from zero on the number line. The absolute value of a number x is denoted by |x| and is defined as follows:

If x is positive or zero, then |x| = x.

If x is negative, then |x| = -x (the negative sign is removed).

Since y > x, the difference (y-x) will be positive. The absolute value of a positive number is the number itself. Therefore, the expression |y-x| without absolute value is simply: y-x

10 stereos must the salesperson sell to make that same amount of money under both plans.

Assume that in order for the salesperson to earn the same amount of money under both schemes, x stereos must be sold.

The salesperson will be paid a salary of $250 + $25 for each stereo sold under the first strategy. So, these are the total earnings:

First plan's total profits are $250 plus $25.

Instead of receiving a salary under the second proposal, the salesperson would be compensated with a $50 commission for each stereo sold. So, these are the total earnings:

Total income under the second plan equals $50x

We can set the two equations for total earnings to be equal in order to determine the value of x:

$250 + $25x = $50x

When we simplify the equation, we obtain:

$250 = $25x

x = 10

The sales person must thus sell 10 stereos in order to.

If the base of the roof is 32 feet long, then the area of the triangular roof is 256 square feet.

In the given scenario, we are provided with information about a triangular roof. It is mentioned that the base of the roof is 32 feet long, and we need to determine the area of the triangular roof.

To calculate the area of a triangle, we need to know the length of the base and the height. In this case, we are given that the height is half the length of the base, which can be expressed as h = (1/2) * b.

Since we are given that the base length, b, is 32 feet, we can substitute this value into the height equation to find the height of the triangle: h = (1/2) * 32 feet = 16 feet.

Now that we have the base length (b = 32 feet) and the height (h = 16 feet), we can use the formula for the area of a triangle: A = (1/2) * b * h.

Substituting the values, we have A = (1/2) * 32 feet * 16 feet = 256 square feet.

Therefore, the area of the triangular roof is determined to be 256 square feet. This represents the amount of surface area covered by the triangular section of the roof.

Let the base of the triangular roof be denoted by b, and its height be denoted by h. We are given that

h = (1/2) * b, and that

b = 32 feet.

We can use this information to find the area A of the roof as follows:

A = (1/2) * b * h

 = (1/2) * 32 feet * (1/2) * 32 feet

 = 256 square feet

Therefore, the area of the triangular roof is 256 square feet.
