Answer: 360 learners

Step-by-step explanation:

There are 30 learners per every 1 teacher. So for 12 teachers, there are 30 x 12 learners, which is equivalent to 360 learners.

In response to the question, we may say that Therefore, the cost of a equation calculator is $10.7 and the cost of a protractor is $1.9.

Let the cost of one calculator be c and the cost of one protractor be p. Then we can write two equations based on the information given:

40c + 30p = 485 (Equation 1)

20c + 20p = 252 (Equation 2)

We can simplify Equation 2 by dividing both sides by 20:

c + p = 12.6 (Simplified Equation 2)

Now we can solve this system of equations using substitution. Solving Equation 2 for c, we get:

c = 12.6 - p

Substituting this expression for c into Equation 1, we get:

40(12.6 - p) + 30p = 485

Expanding and simplifying:

504 - 40p + 30p = 485

Solving for p:

-10p = -19

p = 1.9

Substituting this value for p into Simplified Equation 2, we get:

c + 1.9 = 12.6

Solving for c:

c = 10.7

Therefore, the cost of one calculator is $10.7 and the cost of one protractor is $1.9.

Answer:

x = 4/7 and y = 48/7

Step-by-step explanation:

We need to solve the system of equations using elimination method

-3x + 2y = 12....... equation 1

9x + y = 12...........equation 2

Multiply the 2nd equation with 2

18x + 2y = 24 ............equation 3

Now, subtracting equation 3 from equation 1

- 3x - 18x + 2y - 2y = 12 - 24

-21x = 12

x = 12/21 = 4/7

-3(4/7) + 2y = 12

-12/7 + 2y = 12

2y = 12 + 12/7

2y = 96/7

y = 48/7

Therefore, the   system of equations using elimination. −3x + 2y = 9 x + y = 12 is x = 4/7 and y = 48/7

The volume of the solid is 9375 cubic units with a semicircular base of radius 15 and square cross sections perpendicular to the base and parallel to the diameter.

Many perpendicular lines may be seen in nature. The sides of a set square, the arms of a clock at different times of the day, the corners of a blackboard, a window, and the Red Cross emblem are other examples.

Here,

Let x be the height of the washer and h be the width of the square part of the washer. Then, the radius of the circular hole in the washer is 15 - x, so the width of the washer is 2 * (15 - x). The volume of each washer is then given by:

V = π * (15 - x)^2 * x + h^2 * x

where h^2 = (2 * (15 - x))^2

Expanding h^2, substituting into the expression for V, and simplifying, we get:

V = π * (15 - x)^2 * x + 4 * (15 - x)^2 * x

= 5πx(15 - x)^2

The total volume of the solid is given by the definite integral of V from 0 to 15:

V = 5π ∫_0^15 x(15 - x)^2 dx

This integral can be evaluated using integration by substitution. Let u = 15 - x, so that du = -dx and x = 15 - u. Then:

V = 5π ∫_0^15 (15 - u) * u^2 * (-du)

= 5π ∫_15^0 u^2 * (15 - u) du

= 5π * [u^3/3 * (15 - u) - u^2/2 * (15 - u)^2 + u * (15 - u)^3/3]_0^15

= 5π * (225/3 - 15 * (225/2) + (15^4)/4)

= 5π * (225/3 - 3375/2 + 3375)

= 5π * (5625/3)

= 9375π

So the volume of the solid is 9375 cubic units of the solid with a semicircular base of radius 15 and cross sections perpendicular to the base and parallel to the diameter that are squares.

The dependent variable in this research question is the birth rate in Phoenix, AZ.

This can be represented mathematically as B, where B represents the birth rate in Phoenix, AZ. We can calculate the birth rate by taking the total number of live births in Phoenix, AZ (L) and dividing it by the total population in Phoenix, AZ (P), and then multiplying by 1,000. B = (L/P) * 1000.

For example, if there were 10,000 live births in Phoenix, AZ in a given year, and the population of Phoenix, AZ in that same year was 2,500,000, then the birth rate in Phoenix, AZ would be dependent variable as follows: B = (10,000/2,500,000) * 1000 = 4. This would mean that the birth rate in Phoenix, AZ is 4 births per 1,000 individuals.

The probability of your friend getting a lemon-lime-flavored drink and you getting an orange-flavored drink is 5/18.

Probability is defined as the possibility of an event being equal to the ratio of the number of favorable outcomes and the total number of outcomes.

The first bottle you grabbed had a 5/10 chance of being lemon-lime and a 5/10 chance of being orange.

After you gave your friend a lemon-lime, there were 4 lemon-lime drinks and 5 orange drinks left in the cooler. So, the probability of you grabbing an orange drink was 5/9.

Multiplying these probabilities gives the final answer of (5/10) × (5/9) = 25/90 = 5/18.

The price of a round-trip ticket to Las Vegas on Southwest this week is 175 after applying a 12.5% discount.

The formula used to calculate the price of a round-trip airline ticket to Las Vegas on Southwest this week is Price = Original Price - Percentage Discount x Original Price. The original price of the ticket is $200 and it is 12.5% off this week. Therefore, the calculation of the price of the ticket this week is Price = 200 - 0.125 x 200 = 175. This means that the price of the round-trip ticket to Las Vegas this week is 175.

The 12.5% discount is calculated by taking the percentage discount and multiplying it by the original price. This result is then subtracted from the original price to get the discounted price. For example, if the original price of the ticket is 200 and the discount is 12.5%, then the calculation is 200 - 0.125 x 200 = 175. Therefore, the discounted price of the ticket this week is 175.

In conclusion, the price of a round-trip ticket to Las Vegas on Southwest this week is 175 after applying a 12.5% discount. The discount is calculated by taking the percentage discount and multiplying it by the original price, and then subtracting that result from the original price.

Because lines a and b are parallel and lines e and f are parallel, the value of "x" is 82 degrees.

Parallel lines are coplanar infinite straight lines that do not cross at any point in geometry. Parallel planes are planes that never intersect in the same three-dimensional space. Parallel curves are those that do not touch or intersect and maintain a constant minimum distance. Parallel lines are lines that are always the same distance apart in a plane. Parallel lines never cross. Perpendicular lines are those that connect at a straight angle (90 degrees). Parallel lines are lines in a plane that never intersect, no matter how far they are extended. The distance between the parallel lines is continuous since they never intersect.

Here,

Remember that vertical angles are generated by crossing lines that form two non-adjacent angles. These angles are congruent because they have the same vertex.

Take a look at the attached figure. Because lines "a" and "b" are parallel, the angles 82° and x° are vertical angles. As a result, they are congruent.

95% t-interval for a population mean is Confidence Interval = [14.446, 15.554]

In statistics, estimating the value of a population parameter, like a population proportion or a population mean, is a common goal.

We normally choose a small, random sample to estimate these values, and then we compute the sample proportion or sample mean.

Then, in order to express our uncertainty over these estimations, we build a confidence interval.

To determine a confidence interval for a population proportion, we use the following formula:

The confidence Interval is equal to

Here is how to determine a population mean's 95% confidence interval:

The confidence Interval is equal to x z*(s/n).

Confidence Interval is equal to 15 1.96*(4/25).

The nonzero vector orthogonal to the plane through the points P, Q, and R is [-8/13, -8/13, -12/13].

To find a nonzero vector orthogonal to the plane through the points P, Q, and R, we can use the cross product of two vectors that lie in the plane.

Let's find the vectors PQ and PR, which can be found by subtracting the coordinates of P from the coordinates of Q and R:

PQ = Q - P = (-2, 1, 3) - (1, 0, 1) = (-3, 1, 2)

PR = R - P = (4, 2, 5) - (1, 0, 1) = (3, 2, 4)

Next, we'll take the cross product of these two vectors to find a vector orthogonal to the plane:

n = PQ x PR =

[(1)(4) - (2)(2), (2)(-3) - (3)(1), (3)(3) - (2)(-2)]

= [-8, -8, -12]

This vector is orthogonal to the plane through the points P, Q, and R. To make it a nonzero vector, we can scale it to have magnitude 1:

n = [-8, -8, -12] / sqrt((-8)^2 + (-8)^2 + (-12)^2) = [-8/13, -8/13, -12/13]

So, the nonzero vector orthogonal to the plane through the points P, Q, and R is [-8/13, -8/13, -12/13].
