The exact value of the trigonometric equation cos 0.5θ is equal to 2 / 3.

In this problem we have the exact value of a trigonometric function, from which we must determine the exact value of the half angle by means of the following equation:

cos 0.5θ = √[(1 - cos θ) / 2]

If we know that cos θ = 0.8 and cos 0.5θ > 0, then the exact value of the cosine of the half angle is:

cos 0.5θ = √[[1 - (1 / 9)] / 2]

cos 0.5θ = √[(8 / 9) / 2]

cos 0.5θ = √(8 / 18)

cos 0.5θ = √(4 / 9)

cos 0.5θ = 2 / 3

James has $37.67 now after all his expenses

James had $x, his brother had $y, and his sister had $z when the morning began.

By using algebra,

James's sibling had twice as much money as James.

Now, x =y/2..... (i)

James had $27 fewer dollars than his sister did.

So, x = z - 27 ........ (ii)

⇒  {From equation (1)}

⇒ y/2 = z -27

⇒ y = 2z - 54

⇒ 2z - y =54 ..........(3)

Now, James and his sister each received $12 from his brother.

James now has $(x + 12), his brother now has $(y -24), and his sister now has $(z + 12).

Given that James' sister has twice as much money as James' brother after payoff,

So, z+12/2 = y-24

⇒ z + 12 = 2y - 48

⇒ 2y - z = 50 ......... (4)

The result of resolving equations (3) and (4) is

3y = 54 + 100 = 154

⇒ y =  51.33.

The result of equation (3) is now z = 52.67.

And from equation (1), x = 51.3/2= 25.67

So, now, James has (25.67 + 12) = $37.67

Hence, James has $37.67 now after all his expenses

Using the standard form of the equation of line, the slope of the line represented by the equation 3x-4y=7 is 3/4.

In the given question,

We have to find the slope of the line represented by the equation 3x-4y=7.

The given equation is 3x-4y=7.

To find the slope we first express the given equation in the form of standard equation of line.

The standard form of equation is y=mx+c where m is slope of the equation.

Now expressing the equation in standard form.

3x-4y=7

Subtract 3x on both side

3x-4y-3x=7-3x

-4y=7-3x

Divide by -4 on both side

-4/-4 y=7/-4 - (-3)/(-4) x

Simplifying

y=3/4x-7/4

Now comparing from the standard equation to find the slope(m).

m = 3/4

Hence, the slope of the line represented by the equation 3x-4y=7 is 3/4.

If the mill starts out with 490 tons of grain , then the amount of grain that remains to be sold after milling is 450.8 ton.

In the question ,

it is given that ,

the percent of grain that is lost due to spillage = 3%

the percent of grain that is lost due to mildew = 5%

the total percent of grain lost = grain lost due to spillage + grain lost due to mildew

= 3% + 5%

= 8% of total grain  

given that amount of grain =  490 tons .

amount of grain lost = 8% of 490

= 0.08 * 490

= 39.2 ton ,

So , 39.2 ton of grains is lost .

the amount of grain remain to be sold = 490 - 39.2 = 450.8 ton

Charlie needs to sell 1000 packages per month in order to pay himself a monthly salary of $5000. By using the Equation concept we solved this problem.

A mathematical statement known as an equation is made up of two expressions joined together by the equal sign.

Let the number of packages that Charlie needs to sell is ‘x’

So, According to the question , the below equation has been formed,

10x – (1500 + 3.50x) = 5000

10x – 1500 – 3.50x = 5000

6.50x = 5000+1500

6.50x = 6500

x = 6500/6.50

Answer:

Step-by-step explanation:

The measure of angle B is 40 degrees.

In this question, we have been given angle A and angle B are supplementary angles.

m∠A=(4x−16)°

and m∠B=(x+1)°

since angle A and angle B are supplementary angles,

angle A + angle B = 180°

So we get an equation,

(4x − 16)° + (x + 1)° = 180°

5x - 16 + 1 = 180

5x = 180 + 15

5x = 195

x = 39

So, x + 1 = 39 + 1

Solving the first inequality

2x - 2 > -8

Add 2 to both sides of the inequality

2x -2 + 2 > -8 + 2

2x > -6

Divide both sides by 2

2x/2 > -6/2

x > -3

Solving the second inequality
