Answer:

C. Cos(28) = \frac{15}{17}

Step-by-step explanation:

Recall: SOHCAHTOA

Thus,

Cos(\theta) = \frac{Adjacent}{Hypotenuse}

Reference angle = 28°

Adjacent = 15

Hypotenuse = 17

Plug in the values

Cos(28) = \frac{15}{17}

Consider an election with 681 votes a) If there are 5 candidates, what is the smallest number of first-place votes a candidate c
joja [24]

Answer:

137 votes

Step-by-step explanation:

considering an election with 681 votes and 5 candidates up for the election

dividing the votes among'st 5 candidates

= 681 / 5 = 136.2  hence the least number of first-place votes needed by a candidate using the plurality method  would be = 137 votes

136.2 + 136.2 + 136.2 + 136.2 + 136.2 = 681 ( dividing the votes equally )

136 + 136 + 136 + 136+136 = 680

hence the remaining vote = 681 - 680 = 1

least first-place vote = 136 + 1 = 137 votes

Why there must be at least two lines on any given plane
ratelena [41]
Although theoretically there are infinite lines in space and in a plane, too, at least three non collinear points are necessary to define a plane. Two intersecting lines will therefore be necessary to define it (two points create a line); these intersecting lines are the ones to help define coordinates (x,y).

What is the length of each side of a square that has the same area as a rectangle that is 14 mm long and 16 mm wide? Round to th
swat32
1. You have the following information:

 - <span> The square has the same area as a rectangle.
 - The dimensions of the rectangle are: 14 mm long and 16 mm wide.

 2. You must use the formula for calculate the area of a square, which is shown below:

 A=S</span>²

 "A" is the area of the square.<span>
 "S" is the lenght of the side of the square. (It is important to remember that the sides of a squre have equals lenghts.

 3. The square and the rectangle have the same area. Therefore:

 Arectangle=(14 mm)(16 mm)
 Arectangle=224 mm</span>²
<span>
 A=224 mm</span>²
<span>
 4. Now, you must substitute the value A=224 mm</span>² into the formula A=S² and clear "S":
<span>
 A=S</span>²
<span> S=</span>√A
<span> S=</span>√(224 mm²)
<span> S=15 mm

 The answer is: 15 mm

The length of a rectangle is 4 centimeters more than twice its width. If the perimeter of the rectangle is 86 centimeters, find
garik1379 [7]

width = 13

length = 30

p=2l + 2w

86 = 2(2w+4) + 2w

86 = 4w + 8 + 2w

86= 6w + 8

78 = 6w

13 = w


86 = 2l + 2(13)

86 = 2l + 26

60 = 2l

30 = l


check your work.

l is 4 centimeters more than twice w

twice w = 26

plus 4 = 30



i hope you understand. ask questions if not
