Answer:

300 non student tickets were sold

Step-by-step explanation:

Let's solve the equation step by step,

In order to solve for how many non student tickets were sold, let's make an equation

5.50x + 8.00y = 5700 --------(equation 1)

x + y = 900 ---------------(equation 2)

Let's solve for x and y

5.5x+8y=5700;x+y=900

Rewrite equations:

x+y=900;5.5x+8y=5700

Step: Solve x+y=900 for x:

x+y=900

x+y+−y=900+−y(Add -y to both sides)

x=−y+900

Step: Substitute−y+900forxin5.5x+8y=5700:

5.5x+8y=5700

5.5(−y+900)+8y=5700

2.5y+4950=5700(Simplify both sides of the equation)

2.5y+4950+−4950=5700+−4950(Add -4950 to both sides)

2.5y=750

2.5y/2.5 = 750/2.5

(Divide both sides by 2.5)

y=300

Step: Substitute300foryinx=−y+900:

x=−y+900

x=−300+900

x=600(Simplify both sides of the equation)

Answer:

w = -7.04 and 1.705

Step-by-step explanation:

First lets distribute.

We have 8w-6w(w-4), so let's distribute the -6w to w and -4

8w-6w^2+24w = 2(w+9)

Now for the other side we distribute 2 to w and 9

8w-6w^2+24w = 2w +18

Now we combine like terms

6w^2+32w = 2w +18

Carry both 2w and 18 to the other side

6w^2 +30w -18 = 0

Now we can factor the equation, i used the quadratic method which is x= -b+- the square root of b^2-4ac /2a (in this case x would be w)

Plugging that in:

x= -32 +- square root of 32^2 -4(6 * -18) / 2(6)

-32 +- square root of 1024 +1728 / 12

-32 +- square root of 2752 /12

-32 +- 52.46 /12

x = -32 - 52.46/12   and  -32 + 52.46/12

x=  -84.46/12      and      20.46/12

x= -7.04  and  1.705

so w = -7.04 and 1.705

EF and BC in the trapezoid below are parallel. if ED=35, BC=63, and DC=28

Find the length of BD if EF = 45. Not all figures are rendered to scale.

A trapezoid is a quadrilateral with one pair of opposite sides parallel. It can have right angles (a right trapezoid), and it can have congruent sides (isosceles), but those are not required.

The base angles and the diagonals of an isosceles trapezoid are equal. The intersection point of the diagonals is collinear to the midpoints of the two opposite sides. Opposite sides of an isosceles trapezoid are of the same length or congruent to each other.

Answer: To find the value of x, bring the variable to the left side and bring all the remaining values to the right side. Simplify the values to find the result.

Answer:

85 degrees

Step-by-step explanation:

a line equals 180 degrees.

so 180-140= 40 degrees one of the missing angles in the triangle.

180 degrees is the full amount of degrees the angles of a triangle can equal.

So we have to add up the angles we know...

55+40=95 degrees

and subtract them from 180...

180-95=85 degrees

The largest size of identical felt squares that can be used to cover the top of rectangle is 5 squares of side 24cm.

The rectangle is a 2-dimensional figure with length and breadth which may or may not be same. A square is also a 2-dimensional figure with equal length of its sides.

When the dimensions of rectangle are given, it's are is given as the product of the sides of the rectangle which is given as:

Area of rectangle = Length × Breadth = 60 × 48 = 2880 cm square

The length of the square that entirely covers up the top side i.e., rectangular top can be determined by hit and trial mechanism starting from the lowest whole number in order to determine the length of largest squares of equal dimensions. Then comparing the area of the rectangular top and product of number of squares needed and area of each square, we can find the largest size of the square.

Area of square = length × length = l²

Since, Area of rectangular top = No. of squares × Area of 1 square

Therefore, 2880 = N (l²)

Putting N =1, 2, 3, 4, 5 and so on, we find that when N = 5, the value of square root of l is a perfect whole number.

Hence, 2880 = 5 × (l²)

l = √576 = 24

Thus, 5 squares of side 24cm will be used to cover the rectangular top entirely.

Using Dot product

Two vectors x and y are said to be orthogonal if their dot product is zero

⇒ x.y = 0

This is because orthogonal vectors are make an angle of 90° with each other and therefore θ becomes 90°

Dot product is given by :

x.y = x*y*cosθ = xycos90°

∵cos90° is zero , x.y=0 for orthogonal vectors.

Let u,v,y be vectors in R

y is orthogonal to u and v

⇒ y.u = 0   and  y.v=0

Now, we have to prove that y is orthogonal to (u+v)

The dot product of these vectors is given by:

y.(u+v) = y.u + y.v  (Dot product is distributive) = 0 + 0 = 0

∵The dot product is zero , vector y and (u+v) are orthogonal
