In a survey of music preferences, 81 out of 450 students said that they
preferred country music. What percent of the students preferred country
music?

Answer:

Area = 396 units²

Step-by-step explanation:

Let's assume:

Length = 2c - 5

Width = 5c + 9

Perimeter = 2(L + W) = 106 units

Thus:

2[(2c - 5) + (5c + 9)] = 106

Find the value of c

2[2c - 5 + 5c + 9] = 106

2[7c + 4] = 106

14c + 8 = 106

14c = 106 - 8

14c = 98

Divide both sides by 14

c = 98/14

c = 7

✔️Area of the rectangle = Length × Width

Area = (2c - 5)(5c + 9)

Plug in the value of c

Area = (2×7 - 5)(5×7 + 9)

Area = (14 - 5)(35 + 9)

Area = (9)(44)

Area = 396 units²

Answer:

8.3 is to 1d.p so to find the error interval, you divide 0.1 by 2 = 0.05

8.3 + 0.05 = 8.35

8.3 - 0.05 = 8.25

8.25<y<8.35

You solve this through error and trial.

The is to get two matching numbers at both sides.

X 2x + 3 = 3 (x + 1) - x Answer

0 2(0) + 3 = 3 (0 + 1) - 0 3 = 3

1 2(1) + 3 = 3 (1 + 1) - 1 5 = 5

You do this all the way to ten. So far, we know x = 0 and x = 1 is correct

Answer:

8

Step-by-step explanation:

Since 24 is the original length, you would have to see what number to divide by to get 6.

24 divided by 4 is 6.

Now we know that 1/4 is the scale factor, so apply that to 32.

32 divided by 4 is 6

That's your answer!

Answer:

[tex]18e^2f^3-12e^2f = 6e^2f(3f^2-2)[/tex]

Step-by-step explanation:

Given

[tex]18e^2f^3-12e^2f[/tex]

Required

Factorize:

[tex]18e^2f^3-12e^2f[/tex]

Express 18 as 6 * 3 and 12 as 6 * 2

[tex]18e^2f^3-12e^2f = 6*3e^2f^3-6*2e^2f[/tex]

Factor out 6

[tex]18e^2f^3-12e^2f = 6(3e^2f^3-2e^2f)[/tex]

Factor out [tex]e^2[/tex]

[tex]18e^2f^3-12e^2f = 6e^2(3f^3-2f)[/tex]

Factor out f

[tex]18e^2f^3-12e^2f = 6e^2f(3f^2-2)[/tex]

Answer:

[tex]\boxed{\textsf{ The roots of the quadratic equation is \textbf{ (-4) and 3 }.}}[/tex]

Step-by-step explanation:

A quadratic equation is given to us . Here we aren't given what to do with it. So , lets find out the roots of the equation . The given quadratic equation is :-

[tex]\sf\implies 4x^2+x-3 =0[/tex]

Now with respect to Standard form ax²+bx + c . The roots of the equation can be find out by the quadratic formula also known as " Shreedharyacharya's Formula " .

Quadratic Formula :-

[tex]\boxed{\boxed{\sf x =\dfrac{-b\pm \sqrt{b^2-4ac}}{2a}}}[/tex]

Now with respect to Standard Form we have ,

• a = 4 •b = 1 •c = (-3)

Put on the respective values :-

[tex]\sf\implies x = \dfrac{-b\pm \sqrt{b^2-4ac}}{2a} \\\\\sf\implies x =\dfrac{-1\pm\sqrt{1^2-4(1)(-3)}}{2(1)}\\\\\sf\implies x =\dfrac{-1\pm \sqrt{1+48}}{2}\\\\\sf\implies x =\dfrac{-1\pm \sqrt{49}}{2}\\\\\sf\implies x = \dfrac{-1\pm 7 }{2}\\\\\sf\implies x =\dfrac{-1-7}{2},\dfrac{-1+7}{2}\\\\\sf\implies x =\dfrac{-8}{2},\dfrac{6}{2}\\\\\sf\implies \boxed{\pink{\sf x = (-4) , 3 }}[/tex]

Answer:

6,000 & 19,200

Answer:

2 hours

Step-by-step explanation:

To solve this question, we can convert the fraction into decimal form momentarily, so that 5 1/2 is now 5.5, and 3 1/2 is now 3.5. We know that Sara has already driven 3.5 hours, and it takes 5.5 to get to her aunts house. To dins how much longer Sara has left to drive, simply subtract the total amount of hours by the hours already completed:

5.5 - 3.5 = 2.0

Meaning, Sara has 2 hours left to drive

Answer:

x = 6

Step-by-step explanation:

A vertical asymptote is a vertical line going through the x-axis at an x-value that x is not actually allowed to have.

In this case, we have a 'rational' function, meaning there is a 'ratio' or fraction involving the variable x.

With these 'rational' or fractional expressions, we always have to watch out to make sure we never have a denominator equal to zero, because division by zero is not defined. It is meaningless.

The denominator x-6 will equal zero if x is 6, so x cannot actually ever be 6.

That is where the vertical asymptoe goes: a vertical line with the equation x = 6.

The value of x is 6.

Answer:

23 is a prime number. 11 is a prime number. 25 is a composite number. and 19 is a prime number.

Step-by-step explanation:

Hi there!

23 is a prime number because it has only two factors - 1 and itself.

Remember, a factor is a number that a number can be evenly divided by. So 3 is not a factor of 23.

11 is prime as well.

25 is a composite number because it's last digit is 5. If a number's last digit is 5, then it's divisible by 5. Therefore, it's composite.

19 is a prime number.
