The number of students in the school bus = 36 students
The number of adults in the school bus = 4 adults
So,
Total number of people on 1 school bus = number of students + number of adults
Total number of people on 1 school bus [tex]= 36 + 4[/tex]
[tex]= 40 \ \text{people}[/tex]
Now,
Total number of people on 6 school buses = Total number of people on 1 school bus x 6
Total number of people on 6 school buses [tex]= 40 \times 6[/tex]
[tex]= 240 \ \text{people}[/tex]

A trazpodizi has an aera of 35 mm2 what is the height
The height of the trapezium is 5mm, given that the two parallel sides have lengths of 6mm and 8mm, and the area of the trapezium is 35mm².
To find the height of a trapezium given its area and the lengths of its parallel sides, we use the formula:
Area = (a + b) * h / 2
where a and b are the lengths of the parallel sides, h is the height, and Area is the area of the trapezium.
In this case, we are given that the area of the trapezium is 35mm², and we know that the two parallel sides have lengths 6mm and 8mm. So, we can substitute these values into the formula and solve for h:
35 = (6+8) x h/2
Simplifying the right-hand side of the equation, we can combine the two lengths of the parallel sides and multiply by h, and then divide by 2 to get:
35 = 14h / 2
Multiplying both sides by 2, we get:
70 = 14h
Dividing both sides by 14, we get:
h = 5
Therefore, the height of the trapezium is 5mm.

a large bag contains marbles of different colors. there are 10 red marbles, 5 blue marbles and 7 yellow marbles. when selecting 3 marbles without replacement, find the probability of selecting 3 red marbles
A large bag contains marbles of different colors. there are 10 red marbles, 5 blue marbles and 7 yellow marbles. when selecting 3 marbles without replacement, the probability of selecting 3 red marbles is 1/54.
The probability of selecting 3 red marbles is 1/54.What is a probability?
Probability refers to the likelihood or chance of an occurrence. The probability of an event occurring is the ratio of the number of favourable outcomes to the total number of possible outcomes.
A fraction or a decimal is used to express it.The total number of marbles in the bag is 10 + 5 + 7 = 22 marbles.
There are ten red marbles in the large bag, so the number of ways to select 3 red marbles from ten red marbles is:
[tex]10C_3 = (10 \times 9 \times 8) / (3 \times 2 \times 1) = 120[/tex]
There are 22 marbles in the bag, therefore, the total number of ways to pick 3 marbles from 22 is:
[tex]22C_3 = (22 \times 21 \times 20) / (3 \times 2 \times 1) = 1540[/tex]
Hence, the probability of choosing 3 red marbles out of the 22 marbles in the bag without replacement is:120/1540 = 1/54

to meet the required weight specification, a total of 30 yards of material must be used for each frame. what is the optimal solution? if ati purchase the professional grade for $8 per yard will optimal solution change?
The optimal solution would be to use $240 worth of professional grade material for each frame.
Describe Optimal Solution?An optimal solution is a solution that provides the best possible outcome for a problem or situation, given a set of constraints or requirements. In mathematical optimization, an optimal solution is the solution that maximizes or minimizes an objective function while satisfying a set of constraints.
In other words, an optimal solution is the solution that is most efficient, effective, or desirable according to a certain set of criteria. It is the solution that achieves the best possible outcome, given the available resources and limitations.
To find the optimal solution, we need more information about the specific weight specification and the cost of different types of materials.
However, if we assume that there is only one type of material available, and that it costs $x per yard, we can set up an equation to find the optimal solution:
30x = cost per frame
If the professional grade material costs $8 per yard, then the equation becomes:
30(8) = $240 per frame
So, the optimal solution would be to use $240 worth of professional grade material for each frame, assuming that it meets the weight specification. If the weight specification requires a different amount of material, or if there are other materials available at different prices, the optimal solution would be different.

A pyramid and a prism share the same base. The prism has 99 edges. How many faces does the pyramid have
A pyramid with a base having n sides will have n + 1 faces, excluding the base. So, the pyramid that shares the same base as the prism will have 16 + 1 = 17 faces.
Let's say the base of the pyramid is a polygon with n sides. There are n faces in the pyramid (excluding the base), each of which is a triangle. Since there is just one base, the number of faces in the pyramid is n + 1.A prism is a polyhedron that is formed when two congruent polygons are joined by parallelograms. As a result, a prism with a polygon base has two polygons as bases and a number of rectangular faces equal to the number of sides of the polygon, which in this scenario is n.There are 2 bases and n rectangular faces in total for the prism. Since the number of edges in the prism is 99, we may express this as:Edges in prism = (Number of edges in each rectangular face × Number of rectangular faces) + (Number of edges in each base × Number of bases)= [tex]4n + 2n = 6n = 99n = 16.5[/tex] faces are in the pyramid = 16 + 1 = 17 faces.

The area of the composite figure is 80ft².
Define area of composite figure?Composite shapes may have overlaps between their perimeter and area.
Although we frequently define any shape's area through its perimeter, these two ideas are distinct. The area determines how much room the shape can store, while the perimeter merely draws the object's exterior border. Hence, the space that a shape encloses within its perimeter or boundary is its area.
Calculating the areas of various fundamental shapes is necessary to determine the area of a composite shape.
Breaking the form down is the easiest method:
Separate the composite shape into its constituent parts.
Each fundamental shape's area should be determined separately.
Add these areas together to determine the composite shape's area.
Here, first the area of the triangle:
1/2 × b × h
=1/2 ×(18-7-7) × 4
= 1/2 × 4 × 4

a. No, w is not in fv1; v2; v3g. There are three vectors in fv1; v2; v3g.
b. There are three vectors in the span of fv1; v2; v3g.
c. No, w is not in the subspace spanned by fv1; v2; v3g. This is because the subspace is the set of all linear combinations of the vectors in the span, and w does not have to be a linear combination of the vectors in the span.
To prove this, we first need to recall the definition of the span: it is the set of all linear combinations of a set of vectors. A linear combination is a sum of the vectors, multiplied by constants. For example, if we have a vector v1, and two constants a and b, then the linear combination of a*v1 and b*v1 is (a + b)*v1. If a vector w is not a linear combination of v1, then w is not in the span of v1.
The same logic applies to the vectors fv1; v2; v3g. If w is not a linear combination of these three vectors, then w is not in the subspace spanned by these three vectors. We can prove this by showing that w cannot be a linear combination of fv1; v2; v3g. This is because the only way to create a linear combination of these vectors is to multiply them by constants, and since w is not one of the vectors, it cannot be multiplied by a constant. Therefore, w is not in the subspace spanned by fv1; v2; v3g.

We are given two expressions as the side lengths of a rectangle we must find the perimeter.
The formula for perimeter of a rectangle is [tex]P=l+l+w+w[/tex]. Judging by this, we will have add up all the sides of the rectangle. Lets start by adding the two length expressions first.
[tex](x+10y)+(x+10y)[/tex]
Add x terms
[tex]2x[/tex]
Add y terms
[tex]2x+20y[/tex].
Now lets add the width terms

Add x squared terms
[tex]14x^2[/tex]
Add x terms
[tex]14x^2-2x[/tex]
Add y terms
[tex]14x^2-2x-18y[/tex]
Now we need to add both of the two expressions together
[tex](14x^2-2x-18y)+(2x+20y)[/tex]
We can bring down our x squared term since we have no like terms
[tex]14x^2[/tex]
Add x terms, which cancel.

Simplify (4x3y − 5x2y + 6y) − (9x3y − 3x2y − 6y).
The simplified expression is −5x³y − 2x²y + 12y.
The given expression is (4x³y − 5x²y + 6y) − (9x³y − 3x²y − 6y). To simplify this expression, we need to distribute the negative sign inside the second set of parentheses and then combine like terms.
Distributing the negative sign inside the second set of parentheses, we get:
(4x³y − 5x²y + 6y) − 9x³y + 3x²y + 6y
Next, we can group the terms that have the same variables and exponents:
4x³y − 9x³y = −5x³y −5x²y + 3x²y = −2x²y 6y + 6y = 12y

Nevertheless, if the query is changed to ask for the angle that measures between 0 & 2 radians for which cos(x) = 0, the response is:
When x is equal to 2 or 3, cos(x) equals 0. The unit circle's corresponding points at these angles are, respectively, (0, 1) and (0, -1).
b. The sin(x) values for these angle measurements are:
As the equivalent point is at (0, 1) just on unit circle, sin(/2) equals 1.Due to (0, -1) being the corresponding point on the unit circle, sin(3/2) = -1.
