sixty-eight percent of valley creek school students attend this year's homecoming dance if 459 students attend the dance how many students are in the school?

Answer:

The correct option is c.

Step-by-step explanation:

Given that,

u = 7i+4j and v = 2i-3j

We need to find the product of u and v. The dot product of two vectors is given by :

[tex]u{\cdot}v=(7i+4j){\cdot} (2i-3j)\\\\=(7i)(2i)+(4j)(-3j)\\\\=14-12\\\\=2[/tex]

So, the dot product of u and v is equal to 2.

Answer:

10.58 N

Step-by-step explanation:

Let us find component of these forces in x and y direction.

The solution along with diagram can be found in attachment.

We have found resultant in X- direction = 6√3 N

resultant in Y- direction = 2 N

therefore net force resultant force = [tex]\sqrt{(6\sqrt3)^2+2^2}[/tex]

= 10.58 N

Answer:

( -2,4) is the slope of this line

Answer:

x = 25

Step-by-step explanation:

75 = (4x - 25)

Since there are no numbers outside of the parentheses, we can remove them.

75 = 4x - 25

Now we can see that we can add 25 to both sides.

100 = 4x

Divide both sides by 4 to isolate x.

25 = x

Check by plugging in the value into the original equation.

75 = 4(25) - 25

75 = 100 - 25

75 = 75

Your answer is correct.

Hope this helps!

Answer:

12x + 3 + 7x - 13 = 180

Step-by-step explanation:

Q and R are Same Side Interior Angles

If you add any two same side interior angles for a trapezoid, they will equal 180 degrees.

Therefore, 12x + 3 + 7x - 13 = 180 degrees

Answer:

12x + 3 + 7x - 13 = 180

Step-by-step explanation:

The top and bottom sides of the trapezoid are parallel, but the sides are not. This means that the two angles that we are trying to find cannot be equal. In this case, this can only mean that both sides can be combined to complete a 180 degree angle. This can also be determined since they are supplementary angles, or angles that are adjacent to the opposite side of another base.

Answer:

D. y - 3 = - 12 ( x - 5)

Step-by-step explanation:

Given

Slope (m) = - 12

Point = ( 5 , 3 ) = ( x1 , y1)

Now

Writing in point-slope equation we get

y - y1 = m( x - x1)

y - 3 = - 12 ( x - 5 )

Answer:

∠10 + 12(3) = 46°

∠15(3) + 1 = 46°

Step-by-step explanation:

the angles are equal because they are corresponding angles

(10+12x) =  (15x+1)

reduce:

3x = 9

x = 3

10 + 12(3) = 46°

15(3) + 1 = 46°

Answer:

No

Step-by-step explanation:

In order for it to be a function, every input (x values on the left) needs to be paired with only 1 output (y values on the right). Notice that 1 is paired with both 2 and 4.  This means it is not a function, but it is paired with two different values.

Step-by-step explanation:

Answer:

1) x = 20. 8

2) x = 42.3

3) x = 13.0

4) x = 42.1

Step-by-step explanation:

1) Use Sine

(Sine = [tex]\frac{opposite}{hypothenuse}[/tex]) Sine 53 = [tex]\frac{x}{26}[/tex]

(sine of 53 is 0.80) 0.80 = [tex]\frac{x}{26}[/tex]

(multiply 26 on both sides) 0.80 x 26 = [tex]\frac{x}{26}[/tex] x 26

(solve) 20.8 = x

2) Use Tan

(Tan = [tex]\frac{opposite}{adjacent}[/tex]) Tan 78 = [tex]\frac{x}{9}[/tex]

(tan of 78 is 4.70) 4.70 =  [tex]\frac{x}{9}[/tex]

(multiply 9 on both sides) 4.70 x 9 =  [tex]\frac{x}{9}[/tex] x 9

(solve) 42.3 = x

3) Use Cosine

(Cosine = [tex]\frac{adjacent} {hypothenuse}[/tex]) Cos 22 = [tex]\frac{14}{x}[/tex]

(cos of 22 is 0.93) 0.93 = [tex]\frac{14}{x}[/tex]

(multiply 14 on both sides) 0.93 x 14 = [tex]\frac{14}{x}[/tex] x 14

(solve) 13.02 = x

(round to the nearest tenth) 13.02 = 13.0

4) Use tan

(Tan = [tex]\frac{opposite}{adjacent}[/tex]) Tan 39 = [tex]\frac{52}{x}[/tex]

(tan of 39 is 0.809) 0.809 = [tex]\frac{52}{x}[/tex]

(multiply 52 on both sides) 0.809 x 52 = [tex]\frac{52}{x}[/tex] x 52

(solve) 42.068 = x

(round to the nearest tenth) 42.068 = 42.1

Answer: w = 136

Step-by-step explanation:

Use the triangle angle sum theorem which states the interior angles of a triangle sum to 180.

14+30+w= 180. Combine like terms.

44+w= 180. Subtract 44 from both sides.

w= 136

Answer:

136°

Step-by-step explanation:

Triangles always equal 180°, so add up the given numbers (in this case, 14 and 30 to get 44) then subtract from 180 to get your answer. Hope this helps!!!

Answer:

1000

Step-by-step explanation

1 liter always equals 1000 milliliters

Answer:

it is 500

Step-by-step explanation:

Answer:

s = 1

Step-by-step explanation:

The sum of the interior angles of a polygon is

sum = 180° (n - 2) ← n is the number of sides

Here n = 5 , then

sum = 180° × 3 = 540°

sum the interior angles and equate to 540

39s + 129 + 79 + 145 + 148 = 540 , that is

39s + 501 = 540 ( subtract 501 from both sides )

39s = 39 ( divide both sides by 39 )

s = 1
