Answer:

B. ∆XYZ, in which m∠X = 10° and m∠Z = 25°

Step-by-step explanation:

∆ABC

m∠A = 10°

m∠B = 145°

m∠C = 180° - (m∠A + m∠B )

= 180° - (10° + 145°)

= 180° - 155°

m∠C = 25°

∆XYZ

m∠X = 10°

m∠Z = 25°

m∠Y = 180° - (m∠X + m∠Z)

= 180° - (10° + 25°)

= 180° - 35°

m∠Y = 145°

so,

m∠A = m∠X = 10°

m∠C = m∠Z = 25°

m∠B = m∠Y = 145°

The rate at which the distance is changing is calculated to be 14.42 miles per hour.

Consider the east direction to be denoted by x and the north direction to be denoted by y, therefore;

dx / dt = 12 mph

dy / dt = 8 mph
x is equal to 4 miles

Consider the distance between them to be s

Time taken by you to travel 4 miles = distance / speed

Time taken by you to travel 4 miles = 4/12 hour

Distance traveled by the friend in that time = speed × time

Distance traveled by the friend in that time = 8 × (4/12) = 2.67 miles

Now we use the Pythagorean theorem,

x^2 + y^2 + s^2 ...... (1)

Substitute, x = 4 miles and y = 2.67 miles

s^2 = 16 + 7.1289 = 23.1289

s = 4.81

Now differentiate equation 1 with respect to t as follows;

2x (dx/dt) + 2y (dy/dt) = 2s (ds/dt)

2(4) (12) + 2(2.67) (8) = 2 (4.81) (ds/dt)

96 + 42.72 = 9.62 (ds/dt)

138.72 = 9.62 (ds/dt)

ds/dt = 138.72/9.62 = 14.42 miles per hour

Thus the distance is changing at the rate of 14.42 miles per hour.

Given the midpoint M(3, 1) and point A(4, 3),then the coordinates of point B are (2, -1).

To find the coordinates of point B, we can use the midpoint formula. The midpoint formula states that the coordinates of the midpoint M(x, y) between two points A(x1, y1) and B(x2, y2) are given by:

x = (x1 + x2) / 2

y = (y1 + y2) / 2

Given that the midpoint M is (3, 1) and the coordinates of point A are (4, 3), we can substitute these values into the midpoint formula and solve for the coordinates of point B.

Let's calculate it step by step:

Step 1: Identify the known values

Coordinates of point A: (x1, y1) = (4, 3)

Midpoint coordinates: (x, y) = (3, 1)

Step 2: Apply the midpoint formula

x = (x1 + x2) / 2

3 = (4 + x2) / 2

Multiply both sides by 2:

6 = 4 + x2

Subtract 4 from both sides:

x2 = 6 - 4

x2 = 2

y = (y1 + y2) / 2

1 = (3 + y2) / 2

Multiply both sides by 2:

2 = 3 + y2

Subtract 3 from both sides:

y2 = 2 - 3

y2 = -1

Step 3: Determine the coordinates of point B

The coordinates of point B are (x2, y2) = (2, -1)

Therefore, the coordinates of point B are (2, -1).

Freezing point depression is directly proportional to the molality of a solution, which is determined by the concentration of solutes in the solvent. the correct option is (b)

The greater the number of particles in a solution, the more the freezing point is reduced. In this question, we must determine which of the given solutes would be expected to cause the smallest lowering of the freezing point of an aqueous solution. This is a question of the colligative properties of solutions.

According to colligative properties, the number of particles present in a solution determines its freezing point. The molar concentration of each solute present in a solution is related to its molality by the density of the solution. Hence, we can assume that the molality of each of the given solutes is proportional to its molar concentration. We can also assume that all solutes are completely ionized in solution. The correct option is (b) 0.2 M CH3COOH.

According to the Raoult's law of vapor pressure depression, the vapor pressure of a solvent in a solution is less than the vapor pressure of the pure solvent.

The reduction in the vapor pressure is proportional to the mole fraction of solute present in the solution. The equation for calculating the freezing point depression is ΔT = Kf m, where ΔT is the freezing point depression, Kf is the freezing point depression constant for the solvent, and m is the molality of the solution. We need to compare the molality of each of the solutes to determine the expected freezing point depression. The number of particles in solution determines the magnitude of freezing point depression. Here, all solutes are completely ionized in solution. For each of the options, we have: Option (a) NaCl produces two ions: Na+ and Cl-, for a total of two particles per formula unit. Therefore, the total number of particles in solution is (2 x 0.1) = 0.2. Option (b) CH3COOH is a weak acid. It is not completely ionized in solution.

However, we can assume that it is ionized enough to produce a small number of particles in solution. Each molecule of CH3COOH dissociates to form one H+ ion and one CH3COO- ion. Hence, the total number of particles in solution is approximately equal to (2 x 0.2) = 0.4. Option (c) MgCl2 produces three ions: Mg2+, and 2Cl-, for a total of three particles per formula unit.

Therefore, the total number of particles in solution is (3 x 0.1) = 0.3. Option (d) Al2(SO4)3 produces five ions: 2Al3+, and 3SO42-, for a total of five particles per formula unit. Therefore, the total number of particles in solution is (5 x 0.05) = 0.25. Option (e) NH3 is a weak base. It is not completely ionized in solution.

However, we can assume that it is ionized enough to produce a small number of particles in solution. Each molecule of NH3 accepts one H+ ion to form NH4+ ion and OH- ion. Hence, the total number of particles in solution is approximately equal to (2 x 0.25) = 0.5. Therefore, among the given options, the smallest freezing-point lowering is expected with 0.2 M CH3COOH.

Thus, we can conclude that  CH3COOH as it is expected to exhibit the smallest freezing-point lowering in aqueous solution.

Step-by-step explanation:

For this question, you need to know several special relationships about circles. A radius goes from the center of a circle to any point on the circle. All the radii (not a typo, plural of radius is radii) are the same size, their measures are equal; we say they are congruent (the symbol is an equal sign with a ~over it)

In the diagram, OA and OB are congruent because they are radii. AC is a tangent, that means that it touches the circle at exactly one point, in this case at A. So since OA is a radius and AC is a tangent, they are perpendicular to each other (makes 90° angles). Then we can subtract 90 - 72 to find the angle OAB. Angle OAB is 14°. In triangle AOB, which has two sides the same, the opposite angles will also be congruent which means OBA is also 14° (OR you could use the exact same logic for OB perpendicular to BC and subtract, same calculation as before) . Once you have the two 14° angles in the triangle, you can use the fact that all the angles in a triangle add up to 180° So then, 14 + 14 + x =180. Solve this equation to find angle AOB. See image.

The ordered pair (5, 35) in this context indicates that 5 boxed lunches were ordered and the total cost of those lunches was $35.

In the given graph, the x-coordinate represents the number of boxed lunches ordered (in this case, 5), and the y-coordinate represents the total cost of the lunches (in this case, $35). The point (5, 35) indicates the specific combination of the number of boxed lunches and the corresponding total cost on the graph.

The probability that the average number of hours of overtime worked last month by a random sample of 140 employees in the city exceeds 20 hours is approximately 0.9564, or 95.64%.

To find the probability that the average number of hours of overtime worked by a random sample of 140 employees exceeds 20 hours, we can use the Central Limit Theorem (CLT). The CLT states that for a large enough sample size, the sampling distribution of the sample mean approaches a normal distribution, regardless of the shape of the population distribution.

Given that the population mean is 18.9 hours and the population standard deviation is 7.8 hours, we can calculate the standard error of the mean using the formula: standard error = population standard deviation / sqrt(sample size).

For this problem, the sample size is 140, so the standard error is 7.8 / sqrt(140) ≈ 0.659.

To calculate the probability, we need to standardize the sample mean using the z-score formula: z = (sample mean - population mean) / standard error.

In this case, the sample mean is 20 hours, the population mean is 18.9 hours, and the standard error is 0.659. Plugging these values into the formula, we get z = (20 - 18.9) / 0.659 ≈ 1.71.

Now, we can use a standard normal distribution table or calculator to find the probability associated with a z-score of 1.71. Looking up this value in the table, we find that the probability is approximately 0.9564.

Therefore, the probability that the average number of hours of overtime worked last month by a random sample of 140 employees in the city exceeds 20 hours is approximately 0.9564, or 95.64%.

Answer:Holly drank 12 bottles in a week.

Step-by-step explanation:

First change the fraction 1 2/5 litre into a decimal, by doing this, we can know how many litres are there in 2/5.

So= 1 2/5

= 2 ÷5 = 0.4

= 1 + 0.4 = 1.4 liters

1.4 liters is the amount of water in a bottle.

Next, also change the fraction 2 2/5 litres into a decimal.

So=2 2/5

= 2÷5 = 0.4

= 2 + 0.4 = 2.4 liters

She drinks 2.4 liters a day.

To find how many bottles she drank in 1 week, we must multiply the amount of water she drinks in a day to the days in a week.

So= 1 week= 7 days

= 1 day= 2.4 liters

So= 2.4 × 7 = 16.8

She drinks 16.8 in a week.

To find how much bottles she drank in a week, we must divide the amount of liters she drank in one week to the amount of liters are there in a bottle.

So= 16.8 ÷ 1.4= 12 bottles

Holly drinks 12 bottles in a week.
