[tex]4\text{sin}^2(\frac{\theta}{2} )\text{cos}^2(\frac{\theta}{2} )=2\text{sin}^2(\frac{\theta}{2} )[/tex]

[tex]4\text{sin}^2(\frac{\theta}{2} )\text{cos}^2(\frac{\theta}{2} )-2\text{sin}^2(\frac{\theta}{2} )=0[/tex]

[tex]2\text{sin}^2(\frac{\theta}{2} )[2\text{cos}^2(\frac{\theta}{2} )-1)]=0[/tex]

[tex]\text{sin}\frac{\theta}{2}=0[/tex]

[tex]\frac{\theta}{2} =n\pi[/tex]

[tex]\theta=2n\pi[/tex] [Here, n = integer]

[tex]\theta=0,\pi,2\pi.....[/tex]

[tex]\text{cos}\theta=0[/tex]

Therefore, [tex]\theta=\frac{\pi}{2},\frac{3\pi}{2}[/tex] [Since, [tex]0\leq \theta < 2\pi[/tex]]

recipe says that 2 cups of rice will serve 6 people. Determine how many people can be served with 10 cups of rice and how many cups of rice you need to serve 45 people. Cups of Rice i need answers

Answers

Answer:

10 cups for 30 people

15 cups for 45 people

Step-by-step explanation:

Since this is a ratio problem and we only need to find the value of one variable (how many people can be served) then we can use the Rule of Three to solve this problem like so...

2 cups  <========>  6 people

10 cups <========>  x people

(10*6) / 2 = x ... cross multiply the two available numbers and divide by the third

30 people = x

We can now see that 10 cups of rice can feed 30 people ... Now we can use the same process to find the number of cups needed for 45 people.

2 cups  <========>  6 people

x cups <========>  45 people

(45*2) / 6 = x

15 cups = x

1 Thomas uses a graphing calculator to solve the following word problem. Two shirts and five pairs of pants cost $150. Three shirts and four pairs of pants cost $190. Find the cost of a shirt. Select the statements that describe the steps that Thomas can use to solve the problem using his graphing c A Let x equal the cost of a shirt and y equal the cost of a pair of pants. B Solve each equation for y. c Solve each equation for r. D The solution is the point where the lines intersect. E The solutions are the points where the lines intersect the y-axis.​

Answers

Answer:

The correct options are;

A. Let x equal the cost of a shirt and y equal the cost of a pair pants

B. Solve each equation for y

D. The solution is the point where the lines intersect

Step-by-step explanation:

The cost of two shirts and five pants = $150

Three shirts and four pairs of pants = $190

Let x = The cost of a shirt  and y = the cost of a pair of pants

We have;

2·x + 5·y = 150

3·x + 4·y = 190

We solve each equation for y, to get;

For the first equation, we have;

2·x + 5·y = 150

5·y = 150 - 2·x

y = 150/5 - 2/5·x = 30 - 2/5·x

y = 30 - 2/5·x

For the second equation, we have;

3·x + 4·y = 190

4·y = 190 - 3·x

y = 190/4 - 3/4·x = 47.5 - 3/4·x

y = 47.5 - 3/4·x

The solution is the point where the two lines intersect, which is given as follows;

y = y

47.5 - 3/4·x = 30 - 2/5·x

17.5 = 3/4·x - 2/5·x = 7/20·x

x = 20/7 × 17.5 = 50

The cost of a shirt = x = $50

The cost of a pair of pant = y = 30 - 2/5·x = 30 - 2/5 × 50 = 10

The cost of a pair of pant = $10.
