The senior classes at high school A and high school B planned separate trips to the county fail. The senior class at high school A rented and filled 7 vans and 12 busses with 640 student. High school B rented and filled 12 vans and 6 busses with 456 students. Each van and each bus carried the same number of students. Find the number of students in each van and each bus.

The value of 2[tex]\sqrt{12xy^{2} }[/tex] is 4y[tex]\sqrt{3x}[/tex].

According to the question,

We have the following expression:

[tex]2\sqrt{12xy^{2} }[/tex]

Now, we know that the square root of [tex]y^{2}[/tex] is y.

And the square root of 12 is [tex]2\sqrt{3}[/tex].

(More to know: we have the perfect square root of numbers. For example, the perfect square root of 36 is 6 and the perfect square root of 100 is 10. In the same way, there are perfect cube roots of numbers. For example, the perfect square root of 27 is 3.)

So, by putting the values of these terms in the square root, we have the following expression:

2*y*2[tex]\sqrt{3x}[/tex]

4y[tex]\sqrt{3x}[/tex]

Hence, the value of the given expression after solution is 4y[tex]\sqrt{3x}[/tex].

If the store's cost for the incentives was $103.The amount of  each incentive that were given away is: Free Rental  5, Box of popcorn 54.

Let Free Rental = r

Let Box of popcorn  = p

Total incentives:

r+p=59

r= 59-p Equation 1

r×1+p×2=103

r+2p=103 Equation 2

Put the value of r in (eq 2) from (eq 1)

r+2p=103  (eq 2)

59-p+2p=103

59+p=103

p=103-59

p=44

Put the value of p in (eq 1)

r=49-p...........(1)

r=49-44

r= 5

Free Rental = 5

Box of popcorn = 59 -5

The measure of angle KJL from the given figure is 84°.

Given that, 3(m∠LJM)=2(m∠KJL) and m∠KJM=140°.

An angle is formed when two straight lines or rays meet at a common endpoint. The common point of contact is called the vertex of an angle.

Here, m∠KJM=m∠LJM+m∠KJL

Now, (m∠LJM)=2/3 (m∠KJL)

140°= 2/3 (m∠KJL) + m∠KJL

⇒ [2(m∠KJL)+3(m∠KJL)]/3 = 140°

⇒ 5m∠KJL=420°

⇒ m∠KJL=420°/5

⇒ m∠KJL=84°

Hence, the measure of angle KJL from the given figure is 84°.

Answer: slope = 0

Step-by-step explanation:

The equation of straight line can be expressed in the form y = mx + b, which is referred to as slope intercept form.

In this equation, m represents the slope of the line, y is the y-coordinate of an arbitrary point along the line and x is the x-coordinate of the same point, and b is the location where the line intercepts the y-axis of the graph.

if y = 16, then the slope of the line, m, must be 0.

y = mx + b

y = (0)x + b

y = b

In other words, the line described by the equation y = 16 is a horizontal line that passes through the y-axis at the point (0,16).

The required solution will be -30 which is expressed as an integer.

To represent this in a general context, we may utilize functions that are referred to in terms of the number tossed.

We know that if the number he gets is an even number, he will get 5 times the number.

As a result, the function for when the integer x is even is f(x) = 5x.

If the number is an odd number, he will lose 10 times the number.

As a result, the function for when the integer x is odd is f(x)=-10x.

Finally, Joe tosses a 3, which is an odd integer, hence the function we will represent is f(x) = - 10x.

For any triangle created by points u, v, and any point on the line r t other than s, it will be an isosceles triangle.

Isosceles triangle, in geometry, refers to a triangle that has at least two equal length sides. The isosceles triangle sometimes is specified as having exactly two sides of equal length, and sometimes as having at least two sides of equal length. The triangle which has at least two sides of equal length includes the equilateral triangle as a special case. An isosceles triangle has two sides that are congruent to each other and the third side which is unequal to the other two sides is called the base of the isosceles triangle. The two angles opposite to the equal sides are congruent to each other. Hence, in the given situation, any triangle created by  u, v, and any point on the line r t other than s, will be an isosceles triangle as the sides UR and UV will always be equal.

The constant of variation of the distance is 13.5 miles

From the question, we have the following parameters that can be used in our solution:

Distance cycled = 9 miles

Number of hours = 2/3 of an hour

From the above parameter, we can calculate the constant of variation

The constant of variation is calculated as

Constant of variation = Distance cycled/Number of hours

Substitute the known values in the above equation

So, we have the following equation

Constant of variation = 9/(2/3)
