The distance between points A and B is 2 units.

To find the distance between two points in a coordinate plane, we can use the distance formula:

distance = sqrt((x2 - x1)^2 + (y2 - y1)^2)

where (x1, y1) and (x2, y2) are the coordinates of the two points.

Using this formula, we can find the distance between points A (-3,1) and B(-1,1) as follows:

distance = sqrt((-1 - (-3))^2 + (1 - 1)^2)

distance = sqrt(2^2 + 0^2)

distance = sqrt(4)

The measure of angle B in the right-angled triangle ACB is 63 degrees.

What is a triangle ?

A triangle is a polygon with three sides, three vertices, and three angles. The sum of the interior angles of a triangle is always 180 degrees. Triangles can be classified based on their side lengths and angle measures.

In a right-angled triangle, the sum of the two acute angles is always equal to 90 degrees. Therefore, we can find the measure of angle B in the right-angled triangle ACB by subtracting the measure of angle A and the right angle from 90 degrees.

Given that [tex]\angle A = 27^\circ[/tex], we can find the measure of angle B as follows:

[tex]\angle B = 180^\circ - \angle A - \angle C[/tex]

Since the triangle is right-angled at C, we know that [tex]\angle C = 90^\circ[/tex]. Therefore, we can substitute the values of [tex]\angle A[/tex] and [tex]\angle C[/tex] in the equation above to get:

[tex]\angle B = 180^\circ - 27^\circ - 90^\circ[/tex]

Simplifying this expression, we get:

[tex]\angle B = 63^\circ[/tex]

Therefore, the measure of angle B in the right-angled triangle ACB is 63 degrees.

The required area of the given triangle is 63 ft² respectively.

A triangle is a 3-sided polygon that is occasionally (though not frequently) referred to as the trigon.

There are three sides and three angles in every triangle, some of which may be the same.

A unique triangle and plane (i.e., a two-dimensional Euclidean space) are determined by any three non-collinear points in Euclidean geometry.

In other words, every triangle is contained in a plane, and there is only one plane that contains that triangle.

Area of a triangle:

Answer: Let's use the following variables to represent the unknown quantities in the problem:

x: the number of cupcakes purchased

y: the number of muffins purchased

From the problem statement, we can write two equations:

The total amount spent on cupcakes and muffins is $21.50:

2x + 1.25y = 21.50

The number of muffins purchased is one fewer than the number of cupcakes:

y = x - 1

These two equations form a system of equations that can be solved simultaneously to find the values of x and y.

Substituting equation 2 into equation 1, we get:

2x + 1.25(x - 1) = 21.50

Simplifying and solving for x:

2x + 1.25x - 1.25 = 21.50

3.25x = 22.75

x = 7

Now that we know x, we can use equation 2 to find y:

y = x - 1 = 7 - 1 = 6

Therefore, the customer purchased 7 cupcakes and 6 muffins, spending a total of $21.50.

Step-by-step explanation:

The price of each book must be either $38.53 or $10.8 to generate a total sales revenue of $1,24,875.

If the prices of a book is $16 then 10000 copies will be sold.

For every dollar that increase in price, 300 books will not be sold.

So if the price of a book increases $x then the total price of sold books is given by,

y = (16 + x)*(10000-300x)

Now total sales revenue of the books is $124875, that is, y = 124875.

So, (16+x)*(10000-300x) = 124875

160000 + 10000x - 4800x - 300x² = 124875

35125 + 5200x - 300x² = 0

25 (1405 + 208x - 12x²) = 0

12x² - 208x - 1405 = 0

Solving the above quadratic equation we get,

x = 22.53 or x = -5.20 (Rounding to two decimal places)

So the amount will be either (16+22.53) = $38.53 or (16-5.20) = $ 10.8.

Hence the price must be either $38.53 or $10.8.

Therefore, 11 3/4 - 8 1/2 = 13/4, or 3 1/4 as a mixed number.

A mixed number is a type of number that represents a whole number and a fraction together. It is written in the form of a whole number followed by a fraction, such as 3 1/2. The whole number represents the number of whole units, while the fraction represents the part of a unit.

For example, the mixed number 3 1/2 can be interpreted as three whole units and one half of a unit. Another example of a mixed number is 2 3/4, which represents two whole units and three-quarters of a unit. Mixed numbers are commonly used in everyday life, such as in cooking and measuring, and in mathematical calculations involving fractions.

To subtract mixed numbers like these, we need to convert them to improper fractions first:

[tex]11 3/4 = (4 * 11 + 3)/4 = 47/4[/tex]

[tex]8 1/2 = (2 * 8 + 1)/2 = 17/2[/tex]

Now, we can subtract the fractions:

[tex]47/4 - 17/2[/tex]

To subtract these fractions, we need to find a common denominator. The least common multiple of 4 and 2 is 4 × 2 = 8. We can convert both fractions to have a denominator of 8:

[tex]47/4 = (47/4) * (2/2) = 94/8[/tex]

[tex]17/2 = (17/2) * (4/4) = 68/8[/tex]

Now, we can subtract the numerators:

[tex]94/8 - 68/8 = 26/8[/tex]

Finally, we can simplify the result by dividing both numerator and denominator by their greatest common factor, which is 2:

The probability that Julian will roll a 3 on the next roll is approximately 16.67%. The probability of rolling a 3 on a normal 6-sided die is independent of the previous rolls. This means that regardless of the outcomes of Julian's previous rolls, the probability remains the same.

Explanation

On a 6-sided die, there is 1 favorable outcome for rolling a 3 (the number 3 itself) out of 6 possible outcomes (1, 2, 3, 4, 5, and 6).

To find the probability, you can use the formula:

Probability = (Number of favorable outcomes) / (Total number of outcomes)

In this case:

Probability of rolling a 3 = 1 (favorable outcome) / 6 (total outcomes)

Probability of rolling a 3 = 1/6 ≈ 0.1667 or 16.67%

The number of bags that have zips on them is 28.

To solve this problem, we can use the principle of inclusion-exclusion.

First, we know that the total number of bags is 110.

Next, we know that 24 of the bags have neither zips nor buttons. Therefore, the number of bags that have either zips or buttons is 110 - 24 = 86.

We also know that 32 of the bags have buttons but no zips, and 28 of the bags have zips but no buttons.

To find the number of bags that have both zips and buttons, we can subtract the number of bags that have only buttons from the total number of bags with zips, or vice versa:

Number of bags with both zips and buttons = (Number of bags with zips) + (Number of bags with buttons) - (Number of bags with either zips or buttons)

Number of bags with both zips and buttons = 28 + 32 - 86 = -26

This result is clearly nonsensical, so we can conclude that there are no bags with both zips and buttons.

Therefore, the number of bags that have zips on them is simply the number of bags with zips but no buttons, which is 28.

Sally would have invested $1150 initially in the savings account to satisfy the conditions in the question.

A savings account is a type of bank account that helps people save money over time. It offers a safe and secure way to store money while earning interest on the balance. Unlike checking accounts, savings accounts are intended for long-term storage of funds, with a higher interest rate and regular compounding to help the balance grow. Savings accounts offer flexibility in terms of access to funds and usually allow withdrawals at any time with limits on the number of withdrawals without incurring a fee.

To determine how much money Sally initially invested in a savings account that earns 7.2% annual simple interest, we can use the formula for simple interest: I = Prt. Here, I represents the interest earned, P is the initial principal, r is the annual interest rate as a decimal, and t is the time in years.

Given that Sally earned $745.20 in interest over a period of 9 years with an annual interest rate of 7.2%, we can substitute the values into the formula and solve for P:

I = $745.20

r = 7.2% = 0.072 (decimal)

t = 9 years

Now, P = I / (rt)

P = 745.20 / (0.072 * 9)

P = $1150
