a. The greatest number of packages the teacher can make using all the paintbrushes and paint is 8

b. The number of paintbrushes in each package would be 3 and the number of tubes of paints would be 5

In order to determine the greatest number of packages the teacher can make using all the paintbrushes and paint, we have to determine the highest common factor of the number of brushes and the number of tubes of paint

Highest common factor is the highest factor that is common to two or more numbers:

Factors of 24 = 1,2,3,4,6,8,12 and 24

Factors of 40 = 1, 2, 4, 5, 8, 10, 20 and 40.

Common factors of 24 and 40 = 1, 2, 4, 8

Therefore, the highest common factor is 8.

The number of paintbrushes in each package:

= Number of brushes / number of package

= 24/8

= 3 brushes

The number of tubes of paint:

= number of tubes of paints / number of package

= 40 / 8

= 5 tubes of paints

Approximately it takes 6 years to the population be fewer than 11,000.

If the constant decrease in population be R% per annum, then the population after n years = P(1-R/100)ⁿ.

Given that, A=11,000, rate of interest=8% and P=18,000.

Here, 11,000=18,000(1-8/100)ⁿ

11/18=(1-0.08)ⁿ

The area of the lawn in the scale drawing is approximately 996 square feet.

1. Measure the length and width of the lawn in inches on the scale drawing.

Length = 16.5 inches

Width = 15.5 inches

2. Convert the measurements to feet by dividing the inches by 12.

Length = 16.5/12 = 1.375 feet

Width = 15.5/12 = 1.291 feet

3. Calculate the area of the lawn by multiplying the length and width.

Area = 1.375 x 1.291 = 1.75 square feet

4. Multiply the area by the scale factor (in this case, 560) to get the actual area.

Answer:

(126, 101), (127, 100), (128, 99).

Step-by-step explanation:

The profit from selling one adult ticket is $10.00 and from selling one children's ticket is $5.00.

The total profit from selling A adult tickets and C children's tickets can be represented as 10A + 5C.

The goal is to find combinations of A and C that meet the following conditions:

10A + 5C >= 3750

A + C <= 500

One way to solve this problem is to use a brute force approach and try different values of A and C until we find three combinations that meet the conditions. Another way is to use a more efficient method and find the values of A and C that maximize the number of adult tickets while still meeting the profit and seating limit conditions.

Let's start by finding the maximum number of adult tickets that can be sold while still meeting the profit goal:

10A + 5C >= 3750

10A >= 3750 - 5C

A >= 375 - 0.5C

Since C must be an integer, we can round down the value of A to the nearest integer.
For example, if C = 100, then A >= 125. If we round down A to 125, then the profit from selling 125 adult tickets and 100 children's tickets would be:

10 * 125 + 5 * 100 = 1250 + 500 = 1750

which is less than the profit goal of 3750.

If we increase C by 1, then A would increase by 0.5, and the profit would increase by 5.
So, to reach the profit goal, we need to increase C until the profit is at least 3750.

Let's try C = 101. Then A >= 125.5, which we can round down to 126.

The profit from selling 126 adult tickets and 101 children's tickets would be:

10 * 126 + 5 * 101 = 1260 + 505 = 1765

which is greater than or equal to the profit goal of 3750.

So, the first combination of adult and children's tickets that meets the profit and seating limit conditions is (126, 101).

We can repeat the same process to find the second and third combinations.

For example, the second combination could be (127, 100), and the third combination could be (128, 99).

The final answer is (126, 101), (127, 100), (128, 99).

Answer:

250 $3 tickets and 100 $2 tickets were sold.

Step-by-step explanation:

A segment joining the midpoints of two sides of a triangle is

parallel to the third side

∠ 1 and 144° are same- side interior angles and sum to 180° , so

∠ 1 + 144° = 180° ( subtract 144° from both sides )

∠ 1 = 36°

----------------------

∠ 2 and 56° are corresponding angles and are congruent , so

∠ 2 = 56°

-------------------------

∠ 3 and 56° are a linear pair and sum to 180°

∠ 3 + 56° = 180° ( subtract 56° from both sides )

∠ 3 = 124°

--------------------------

the sum of the 3 angles in a triangle = 180° , then

∠ 1 + ∠ 2 + ∠ 4 = 180° , that is

36° + 56° + ∠ 4 = 180°

92° + ∠ 4 = 180° ( subtract 92° from both sides )

∠ 4 = 88°

--------------------------------

∠ 5 and ∠ 1 are corresponding angles and are congruent , so

∠ 5 = 36°

----------------------------------

Answer:

m∠1 = 36° , m∠5 = 36° , m∠4 = 88°  , m∠3 = 124° , m∠2= 56°

Step-by-step explanation:

m∠1 and 144° are Co-Interior angles, or the angles which are on the same side of the transveral

m∠1 + 144°  = 180°

m∠1 = 36°

angle 5 and 144° are in a linear pair-
144 °+ angle 5 = 180°

m∠5 = 36°

angle 5 + 56° + angle 4 = 180°        because addition of angles of a triangle is 180°

36° + 56° + angle 4 = 180°
angle 4 = 180° - 92°
angle 4 = 88°

56° and angle 3 are in a linear pair

56° + angle 3 = 180°
angle 3 = 124°

angle 3 and angle 2 are Co-Interior angles

angle 3 + angle 2 = 180°
124° + angle 2 = 180°
angle 2 = 56°

The probability that at least one of the disks selected has a number greater than 24 is 127/343.

To find the probability that at least one of the disks selected has a number greater than 24, we can find the probability that all three disks have numbers less than or equal to 24 and subtract this from 1.

The probability that a disk selected from a container has a number less than or equal to 24

24/28= 6/7

Since,

there are 24 disks with numbers less than or equal to 24 out of a total of 28 disks in each container.

We can assume that the selection of a disk from one container is independent of the selection of a disk from another container, so the probability that all three disks selected have numbers less than or equal to 24 is (6/7)³

since we are making three independent selections.

Therefore,

The probability that at least one of the selected disks has a number greater than 24 is 1 - (6/7)³ ,

which simplifies to 343/343 - 216/343 = 127/343

If the measure of ABC = 170°, the measure of QRS is equal to 10°.

In Mathematics, a supplementary angle simply refers to two (2) angles or arc whose sum is equal to 180 degrees.

Additionally, the sum of all of the angles on a straight line is always equal to 180 degrees. In this scenario, we can logically deduce that the sum of angles ABC and QRS are supplementary angles:

m∠ABC + m∠QRS = 180°

Substituting the given parameters into the formula, we have the following;

170° + m∠QRS = 180°

m∠QRS = 180° - 170°

Let's call the radius of the circle "r". The formula for the area of a sector of a circle is given by:

(θ/360) * π * r^2,

where θ is the central angle of the sector in degrees.

In this case, we know that the central angle is 315° and the area of the sector is 504π, so we can set up an equation as follows:

(315/360) * π * r^2 = 504π

Solving for r, we can isolate it on one side of the equation:

r^2 = 504 / (π * (315/360))

To simplify the expression on the right-hand side, we can divide both the numerator and denominator by 45 (which is a factor of both 315 and 360):

r^2 = 504 / (π * (7/8))

Finally, taking the square root of both sides gives us:

r = sqrt(504 / (π * (7/8)))

So the radius of the circle is approximately 17.14 inches.

A recipe for flapjacks uses only syrup sugar butter and oats in the ratio 1:2:2:4. Using this recipe 250g of syrup are needed to make 12 flapjacks. The quantity of oats needed to make 18 of these flapjacks is 375g.

The recipe for flapjacks has a ratio of syrup to sugar to butter to oats of 1:2:2:4. This means that for every 1 unit of syrup, there are 2 units of sugar, 2 units of butter, and 4 units of oats.

We know that 250g of syrup are needed to make 12 flapjacks. To find out how much oats are needed to make 18 flapjacks, we can set up a proportion:

syrup: sugar: butter: oats = 1:2:2:4

250g:x = 12:18

To solve for x, we can cross-multiply and simplify:

250g * 18 = 12x

4500g = 12x

x = 375g

Therefore, we need 375g of oats to make 18 flapjacks using this recipe.

Answer: The measure of Angle A is 46 degrees.

Step-by-step explanation:

Complementary angles are angles that when both added together are equal to 90 degrees. So the measure of angle A plus the measure of angle B is equal to 90 or 3x - 2 + 2x + 12 = 90. Add like terms so you get 5x + 10 = 90. Subtract 10 on both sides you get 5x = 80. Divide by 5 on both sides and you get x = 16. To find the measure of angle A, plug in your x value. So M<A = 3(16) - 2. Ange A is equal to 46. I double checked my answer too and plugged my x value into M<B and got 44. So indeed 44 + 46 = 90.

The equation of the line that passes through (18, 16) and has a slope of 11/8 is 8y = 11x - 70.

The equation of a straight line that passes through a particular point and is inclined at a specific angle to the x-axis can be found using the point slope form. Every point on a line must satisfy the equation for the line in order for it to exist. This implies that a line is represented by a linear equation in two variables. Depending on the facts at hand, there are different ways to find a line's equation. Several techniques include:

Form of point slope, Form of a slope-intercept, Two-point form for intercepting.

The point slope form is given as:

(y - y1) = m (x - x1)

The point is (18, 16) and the slope is 11/8.

Substituting the values we have:

y - 16 = 11/8 (x - 18)

8(y - 16) = 11(x - 18)

8y - 128 = 11x - 198

8y = 11x - 70

Hence, the equation of the line that passes through (18, 16) and has a slope of 11/8 is 8y = 11x - 70.

The set builder form of the set b = {1/10, 1/00, 1/1000} is b = {x | x = 1/10ⁿ, where n is a positive integer}

In mathematics, set builder notation is a concise way of describing a set using a rule or a formula.

Let's explore how we can use set builder notation to write the set b={1/10, 1/100, 1/1000}.

To begin, we need to identify the common property that these elements share. In this case, we can observe that each element is a rational number with a power of ten as the denominator. So, we can write the set b as follows:

b = {x | x = 1/10ⁿ, where n is a positive integer}

In this notation, the vertical bar represents "such that" and separates the description of the element from the rule that defines the set. The letter x is a variable that represents any element that satisfies the rule. We use the power of ten as a common property to describe the set b.

In this set builder form, we can see that b is a set of elements that can be expressed as 1/10 to the power of a positive integer. We can also use set builder notation to define other sets with different properties, such as sets of even numbers or sets of prime numbers.

The rate at which the water level is rising when the water level is 2 cm is 8 cm.

A pyramid's volume is equal to 1/3 of B, where B is the base's area and h is its height. Given that the base is square, B = s2, where s is a base side The volume is therefore 1/3 s2h.

We are aware that the base's side is 8 cm long and the whole pyramid's height is 11 cm. Also, no matter how high the water is, its surface will always form a square with the same proportion to the water's depth as a side of the pyramid's top has to the pyramid's total height. This indicates that s = 8/11 h regardless of the water depth.

So that means that the formula for the volume of the pyramid formed by the water is V = 1/3 (8/11 h)2 h = 64/363 h3.

Separate this as a function of time to get the rate of change of the volume of water :

V = 64/363 h3

dV/dt = 3 (64/363) h2 dh/dt = 192/363 h2 dh/dt

Nonetheless, we are aware that the volume is shifting at a speed of 65 cc every second.  So at any point in time,

65 = 192/363 h2 dh/dt

65 * 363 / 192 = h2 dh/dt

23595 / 192 = h2 dh/dt

(23595 / 192) / h2 = dh/dt

When the level of water (h) is 8, that indicates:

(23595 / 192) / 64 = dh/dt

1.92 = dh/dt

So the water level is rising at the rate of 1.92 cm per second when the water level is 8 cm.
