Does changing the compound inequality x>-3 and x<3 from and to or change the solution set? Explain

Answer:

b = 39

Step-by-step explanation:

Given that,

A rectangle STUV such that, ST = 2b-39 and VU = b

We need to find the value of b.

For a rectangle, the opposite sides are equal such that,

ST = VU

Putting all the values,

2b-39 = b

Taking like terms together,

2b-b = 39

b = 39

Hence, the value of b is 39.

Answer: 1.09090909

Step-by-step explanation:

#7 and #8

Solve these with proportions. Set them up like this:

[tex]\frac{part}{whole} =\frac{percentage}{100}[/tex]

Say I have a question that said "Arjun had Rs. 10, and his friend Raghav borrowed Rs. 5, what percentage of Arjun's amount did Raghav borrow?". 10 is the whole. It is the total amount of money that they have. 5 is the part. You are looking for the percentage. The 100 will always stay the same. Put the values that you know into the proportions, and replace what you don't know with the variable x. Like so:

[tex]\frac{5}{10} = \frac{x}{100}[/tex]

To solve this, use cross multiplication. Multiply the top left with the bottom right, and the bottom left with the top right. You will get:

5(100) = 10x

Simplify.

500 = 10x

Now, to solve this, you must isolate the x. To do this, divide both sides by 10, to get:

50 = x.

50 is your percentage.

You can solve this kind of problem by just remembering the proportion, filling in what you know, and then solving!

#8 and #9

To solve these types of problems, set up an equation.

Say that I had the question "Sowmya is baking cupcakes. She has 10 cups of flour, and she uses 2 cups for each cupcake. How many cupcakes can she bake?

What do you know?

You know she has 10 cups in total. You know that she uses 2 cups per cupcake.

So, you will set up the equation like this:

2x = 10

Where x is the number of cupcakes she makes.

To solve, you will isolate the variable by dividing both sides by 2 to get:

x = 5.

Sowmya can bake 5 cupcakes with 10 cups of flour.

Hope this helps!

Answer:

2.4?

I'm not completely sure but I think that may be the correct answer.

(Edit) Oh it's not. It's 60%. Well ok.

(Edit 2) Thank you for letting me try-.

Answer:

60%

Step-by-step explanation:

We can set this up as the proportion is/of=%/100. So,

12 = %

20 100

First, multiply across with 12x100. 12x100=1,200.

Now, divide 1,200 by 20. 1,200/20=60

Jake got 60% on the test.

Hope this helps!! Have a nice day .,.

Answer:

Following are the solution to the given choices:

Step-by-step explanation:

In point a:

[tex]\to \sec^2x -1 = \tan^2 x[/tex]

In point b:

[tex]\to \frac{1}{\sin x} = cosec x[/tex]

In point c:

[tex]\to \sin x \cot x = \sin x \times \frac{\cos x}{ \sin x}\\[/tex]

                    [tex]= \cos x \\[/tex]

In point d:

[tex]\to \frac{\sin^2 x}{1+ \cos x} = \frac{\sin^2 x}{1+ \cos x} \times \frac{1- \cos x}{ 1- \cos x}[/tex]

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

Answer:

A=10 cm

B=5 cm

Area of square = 25 cm

Step-by-step explanation:

Since that is an equilateral triangle based off the fact that all the sides are the same variable (a) then that means 30 divided by 3 which equals 10. So now we know that a = 10. Lets input that information for the rectangle. Since there are 2 a's that equals 20 and the perimeter is 30 so b has to be 5 since 5 times 2 is 10 plus 20 equals 30. so now we know that a=10 and b=5 so our squares sides are all 5. The area of the square is 25

Answer:  Lena will be able to make 54 cupcakes.

Step-by-step explanation:

If 1/3 cups  has t make 6 cups , then we can set up a proportional relationship and find  out how much 3 cups of milk can make.

[tex]\frac{1/3}{3} = \frac{6}{x}[/tex]     Cross multiply  

1/3x = 18     Multiply both sides by 3.

x = 54  

Answer:

the roots are 5 and 1/2

Step-by-step explanation:

a = 2

b = -11

c = 5

Plug values into formula:  (-b ± √b² - 4ac) ÷ 2a

the discriminant comes out to be √81

(11 + 9) / 4 = 5

(11 - 9) / 4 = 1/2

Answer:

a2

Step-by-step explanation:

Answer:

I believe the answer is 32 degrees. The reason I believe this is because the line VP splits the whole angle and at the right end of the line, closest to letter P both sides make the new two triangles right angles. This leads me to believe that the line VP splits the triangle equally into two parts which means both angle 2 and angle 1 would have to add up to 64 degrees.
