Answer:The x values of the “and” inequality satisfy both inequalities.
The x values of the “or” inequality satisfy one or both inequalities.
Changing the compound inequality from “and” to “or” changes the solution set from the values between –3 and 3 for all real numbers.

Simplify the following expressions and match them with their solution.
a. sec^2x -1
b. 1/sinx
c. sinx cotx
d. sin^2x/1+cosx
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]

Jake got 12 questions correct on a 20 question test. What percent did Jake get correct
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 .,.
Can someone help me with this?
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

Help me out with this question (geometry)
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.

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

Lena has three cups of milk in a refrigerator she needs 1/3 of a cup of milk to make a BATCHES of 6 cupcakes how many cupcakes will need to be able to make with that amount of milk in the refrigerator
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

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:
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.
