Answer:

26

Step-by-step explanation:

130-20%=104

25% of 104 is=26

Answer:

See below

Step-by-step explanation:

I'll provide an example to help you. Let's say we were solving [tex]x^2+5x-7=0[/tex] and we wanted to factor the quadratic on the left side. We can't do that because the factors of -7 don't add up to 5. So we'd have to use the quadratic formula. The quadratic formula is essentially the last resort that will solve all quadratic equations, so it could be seen as a preferred method. But, unless you can factor the quadratic, it's much easier to solve.

Now let's do another one. [tex]x^2+5x+6=0[/tex] for example can be written as [tex](x+2)(x+3)=0[/tex] and we can easily get [tex]x=-2[/tex] and [tex]x=-3[/tex] as solutions since plugging them into the factors would produce 0 (from the Zero Product Property). If we used the quadratic formula, it would take more time to plug in the variables and solve when we can just simply factor.

Hopefully, this explanation helps you to think of your discussion post!

Answer:

The retail price would be $93.6

Step-by-step explanation:

This is because you can divide 130 by 100 to find 1% of such, and you'll get 1.3. Then, multiply 1.3 by 72, which makes 72% of the original price, to come find your answer, $93.6. Hope this helps!

Answer:

Parul's age=7 years

Atul's age=19 years

Step-by-step explanation:

Let present age of Parul be x

Let present age of Atul be y

3 years ago

Parul's age=x-3

Atul's age=y-3

5 years after

Parul's age=x+5

Atul's age=y+5

According to question

y-3=4(x-3)

y-3=4x-12

y-4x+9=0.....(1)

y+5=2(x+5)

y+5=2x+10

y-2x-5=0......(2)

from(1),y=4x-9

Put y in (2)

4x-9-2x-5=0

2x-14

2x=14

x=7

y=19

Parul's age=7 years

Atul's age=19 years

Answer:

Option D is correct.

Step-by-step explanation:

We can tell that

Now, let's simplify.

=> [tex]4x + 2 + \frac{4x-4}{2} = 180[/tex]

=> [tex]4x + 2 + 2x-2 = 180[/tex]

=> [tex]4x + 2x = 180[/tex]

=> [tex]6x = 180[/tex]

=> [tex]x = 30[/tex]

Therefore, Option D is correct.

Hoped this helped.

Answer:

The value is [tex]\frac{1}{16384}[/tex]

Step-by-step explanation:

Here we need to find

[tex]\frac{x^{m+n}\cdot y^{n-m}}{x^{m-n}\cdot y^{n+m}}=x^{m+n-(m-n)}\cdot y^{n-m-(n+m)}\\\\=x^{2n}\cdot y^{-2m}\\\\=2^{2\cdot-1}\cdot 4^{-2\cdot3}\\\\=\frac{1}{2^2\times4^6} \\\\=\frac{1}{16384}[/tex]

Answer:

The value of a function is the actual calculation done at a certain point. The limit is - roughly speaking - the value at points that are “arbitrarily close” to the same point. For most commonly used functions, the value of a function at a point, and the limit at the same point, is the same - at least for most values.

Answer:

Apples cost 50 cents and bananas 25 cents.

please mark brainliest if this helped

Step-by-step explanation:

1) Assign variable (x,y) to apples and bananas.

x=apples

y=bananas

2) Write system of equations for Alice and Betty.

Alice: 4x+8y=4

Betty: 6x+10y=5.5

3) Use substitution, elimination, or graphing to solve for x and y.

x=0.5

y=0.25

Answer:

side MJ was 4 then it became 2 at side SP

side ML was 3 then it became 1.5 at side SR

side LK was 3 then it became 1.5 at side RQ

so we will divide 5 by 2 / 5÷2 = 2.5

Answer:

I couldn't understand what you actually mean. But, I -think you are trying to ask what is the meaning of Knowledge.

Answer: Sarah got 60 questions correct, 15 questions wrong, and she got 20% of the questions wrong.

Step-by-step explanation:

First, let's solve for how many questions Sarah got correct.

80% as a fraction can be simplified as [tex]\frac{8}{10}[/tex]. To find how many questions Sarah answered correctly, we can set up a proprtional relationship as follows:

[tex]\frac{8}{10}=\frac{?}{75}[/tex]

Next, after we cross multiply, 8 X 75 = 600, and 600 ÷ 10 = 60

So, Sarah got 60 out of 75 questions correct.

To find how many she missed, we can simply subtract 60 from 75 to get 15.

So, Sarah got 15 out of 75 questions wrong.

Finally, to find the percentage of the questions that Sarah got wrong, we can use the 15 out of 75 incorrect questions that we found earlier to create a percentage.

15 ÷ 75 = 0.2

0.2 X 100 = 20

So, Sarah got 20% of the questions wrong.
