Answer:

  x = 13

Step-by-step explanation:

You want to find x when one half of the diagonal of a parallelogram is 80 and the other half is 6x+2.

The diagonals of a parallelogram bisect each other, so point Y is the midpoint of each. That means ...

  VY = YX

  80 = 6x +2 . . . . . substitute the given values

  78 = 6x . . . . . . . subtract 2

  13 = x . . . . . . . . divide by 6

0.058% x 663 seats = 39%

Answer:

F = 29

E= 151

D = 90

Step-by-step explanation:

For F:

The angle F is on a 180 degree angle with a degree next to it that is 151. To get the value F subtract 180-151 and you get 29.

For E: If F is 29 then the angle opposite of F is also 29. So again to find the measure of angle E, subtract 180 minus 29 and you get 151.

For D: D is also lying on a 180 degree angle. The angle next to it is 90. To get 180 add 90. 90 is the measure of angle d.

Answer:

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

Angle d is linear pair with a right angle, therefore:

The required equation in terms of r is r = (W - FB) / F

An equation is a mathematical statement given by connecting two expressions by equal sign.

An equation is a mathematical statement with an 'equal to' symbol between two expressions that have equal values.

For example: 3x=9y, 67x = 90+39y

Given that an equation W = F(r + B) we need to solve the equation for r,

Therefore, rearranging for r,

W = F(r + B)

Using the distributive law,

W = Fr+FB

Transposing FB to the LHS

Fr = W - FB

Diving the equation by F

r = (W - FB) / F

Hence, the equation in terms of r is r = (W - FB) / F

Step-by-step explanation:

we know :

sin(2t) = 2×sin(t)×cos(t)

cos(2t) = cos²(t) – sin²(t) = 2×cos²(t) – 1 = 1 – 2×sin²(t)

tan(t) = sin(t)/cos(t)

tan(2t) = sin(2t)/cos(2t) = (2×tan(t))/(1 – tan²(t))

sin²(t) + cos²(t) = 1

as t is in quadrant I, 2t must be in either quadrant I or II.

sin(t) = 7/9

sin²(t) = (7/9)² = 49/81

cos²(t) = 1 - sin²(t) = 1 - 49/81 = 81/81 - 49/81 = 32/81

cos(t) = sqrt(32)/9

sin(2t) = 2×sin(t)×cos(t) = 2×7/9 × sqrt(32)/9 =

A cross section of a cube that is a regular hexagon can only be obtained if the plane passes through the cube at a 60-degree angle with respect to its edges. If a plane is placed in this manner, it will intersect six of the cube's edges at their midpoints, producing a regular hexagon cross section.

The plane that passes through three edges of a cube to produce a regular hexagonal cross section must intersect the edges of the cube at 60 degree angles. This can be achieved if the plane is aligned with the diagonal of one of the faces of the cube, passing through the opposite vertices of the face.

This configuration of the plane will result in a regular hexagonal cross section of the cube as each vertex of the hexagon will correspond to one of the vertices of the cube, and each side of the hexagon will intersect two edges of the cube at 60 degree angles.

Answer:

The new slope is 2,

New y-intercept is - 7

Line is flatter since slope has reduced

Step-by-step explanation:

The f -intercepts and r -intercepts of the function are (0, 180) and (6, 0), (-6, 0),(5, 0)

The intersection of the graph of the function with the y-axis gives y-intercept of that function. The y-intercept is the value of y on the y-axis at which the considered function intersects it.

Assume that we've got: y = f(x)

At y-axis, we've got x = 0, so putting it will give us the y-intercept.

Thus, y-intercept of y = f(x) is y = f(0)

We are given that;

The function is  f ( r ) = ( r − 6 ) ( r + 3 ) ( r − 1 )

Now,

Substituting r=0 for f -intercept

f(0) = (0-6)(0+6)(0-5)

f(0) = 180

The f-intercept is (0, 180);

Solving for the r-intercepts;

Set the function equal to 0.

0 = (r-6)(r+6)(r-5)

(r-6) = 0

r = 6

(r+6) = 0

r = -6

(r-5) = 0

r = 5

Therefore, the r-intercepts will be (6, 0), (-6, 0), and (5, 0)

In the word problems given above, the results are:

1) Let's call the number we're looking for "x". According to the problem, "three times a number" is the same as 60 minus 21, which is 39. So we can write the equation:

3x + 21 = 60

Subtract 21 from both sides:

3x = 39

Divide by 3:

x = 13

Therefore, the number we're looking for is 13.

2)

Let's call the number we're looking for "x" again. According to the problem, "three times the difference between a number and three" is the same as "four times the number". So we can write the equation:

3(x - 3) = 4x

Simplify:

3x - 9 = 4x

Subtract 3x from both sides:

-9 = x

Therefore, the number we're looking for is -9.

3)

Let's call the first of the three consecutive integers "x". The next two would be x+1 and x+2. According to the problem, their sum is 48, so we can write the equation: x + (x+1) + (x+2) = 48

Simplify:

3x + 3 = 48

Subtract 3 from both sides:

3x = 45

Divide by 3:

x = 15

So the three consecutive integers are 15, 16, and 17. To answer the second part of the question, we can substitute these values into the given expression:

3m - z(1st) = 3(16) - 15(15) = 48 - 225 = -177


4)
Let's call the smallest of the three consecutive odd integers "x". The next two would be x+2 and x+4. According to the problem, twice the smallest is seven more than the largest, so we can write the equation:

2x = (x+4) + 7

Simplify:

2x = x + 11

Subtract x from both sides:

x = 11

So the three consecutive odd integers are 11, 13, and 15. The middle number is 13.


5)
Let's call the width of the rectangle "w". According to the problem, the length is 3 cm more than the width, so the length is w + 3. The perimeter is the sum of all four sides, which is:

P = 2w + 2(w + 3) = 4w + 6

We know that the perimeter is 22 cm, so we can write the equation:

4w + 6 = 22

Subtract 6 from both sides:

4w = 16

Divide by 4:

w = 4

So the width is 4 cm, and the length is 7 cm (since it's 3 cm more than the width). To find the area, we use the formula:

A = (L)(W) = (7)(4) = 28 square cm


6)

Let's denote the length of side a as x. Then we know that side b is 3 times the length of side a, or 3x, and side c is 1 more than twice the length of side a, or 2x+1.

Since the perimeter of the triangle is 43 inches, we can write the equation:

a + b + c = 43

Substituting in our expressions for b and c, we get:

x + 3x + 2x + 1 = 43

Simplifying the left-hand side, we get:

6x + 1 = 43

Subtracting 1 from both sides, we get:

6x = 42

Dividing both sides by 6, we get:

x = 7

thus:

a = 7

b= 3x = 21; na d

c = 2x + 1 = 14+1

c = 15

Thus the sum of sides a and b =
21 + 7
