Answer:

[tex]\huge\boxed{\text{E. } \frac{1}{2} }[/tex]

Step-by-step explanation:

When finding the cosine of an angle, we need to note what each terms mean.

Using the acronym SOH CAH TOA, we know that the

Cosine of an angle will be it's

Adjacent side divided by the

Hypotenuse.

The side adjacent to the 60° angle is 1, and the hypotenuse of the triangle is 2. Therefore, the adjacent over the hypotenuse is [tex]\frac{1}{2}[/tex], making the cos of 60°

[tex]\frac{1}{2}[/tex].

Answers

This question is incomplete, the complete question is;

For integers a, b and k, we know that a > 12, b < 20 and a < b. If b=7k, what is the value of k ?

Answer: the value of k = 2

Step-by-step explanation:

Given that;

a > 12

b < 20

a < b

If b = 7k

Now if k = 1 {b = 7k = 7}

b would be equal to 7 but b has to be greater than 20

IT CANT BE

if k = 2 { b = 7k = 14}

b would be equal to 14, a is greater than 12, b has to be less than b; 14 < 20,

a has to be less than than b ( 12 < 14 )

IT IS

if k = 3 {b = 7k = 21}

b would be equal to 21, so b is greater than 20 and a is less than 21

IT CANT BE

Therefore the value of k = 2

A drawing has a scale of 1 mm: 20 cm. What
is the scale factor of the drawing?

Answers

The scale factor of the drawing is 200.

Scale Factor of a Drawing

The first step to take when looking for the scale factor of a drawing is to ensure both measurements are on the same unit.

Given a scale for a drawing to be: 1 mm: 20 cm

1 cm = 10 m

Therefore:

20 cm = 200 mm

Scale factor = 200/1 = 200.

Therefore, the scale factor of the drawing is 200.

Assuming the lines are evenly spaced between the integers, what number, in decimal notation, is represented by the plotted point?

Answers

Answer:

-1.4

Step-by-step explanation:

There are five increments between -2 and -1, so we find the difference between -2 and -1, which is 1. Divide 1 by five (increments)=.2

This means that every increment is worth 0.2.

If we see it from the left to right, from -2, there are 3 increments to the right, so multiply three by 0.2 which is 0.6, add 0.6 to -2, which is -1.4.

Answers

Answer:

3d{\color{#c92786}{-5}}+4d+{\color{#c92786}{5}}=140

3d−5+4d+5=140

3d+4d=140

Combine like terms

{\color{#c92786}{3d}}+{\color{#c92786}{4d}}=140

3d+4d=140

{\color{#c92786}{7d}}=140

7d=140

Divide both sides of the equation by the same term

FINDING 'a'

31 = a + 46 / 2

62 = a + 46

16 = a

FINDING 'w'

* This section looks Non-Isosceles trapezoid so I will be following the rule according it

w + 55 = 180

w = 125

FINDING 'y'

y = 55

- Because of corresponding angles

FINDING 'x'

* In this case it looks like we are still dealing w/ an non-isosceles trapezoid.

x + 60 = 180

x = 120
