To figure how many people liked hip hop, you have to multiply 1/5 by 25


1/5 *25 is 5


To figure out how many students liked country, you do


16%*25 which is 4


25-4-5 is 16


So, 16 students like pop music

A line is drawn on a coordinate grid by the equation x = 6. Which of the following lines would represent a row parallel to it?
elena-14-01-66 [18.8K]

Answer:

D, x = 3

Step-by-step explanation:

to know if a line is parallel, we need to know what kind of line x = 6 is

we can use the mnemonic VUX/HOY to determine the slope, the type of line, and which axis it corresponds to. VUX/HOY stands for:

Vertical line

Undefined slope

X axis

Horizontal line

0 is the slope

Y axis

according to this, the equation x = 6 is a vertical line

now we can start eliminating answer choices

A. a line containing the point (6,2)

the point lies on the line x = 6, as the x-coordinate in the ordered pair is 6. this  is not parallel to the line

B. y = 6

this intersects x = 6 and is not parallel

C. y = 4

this intersects x = 6 as well and is not parallel

D. x = 3

this leaves us with x = 3, which is a vertical line as seen by the equation and therefore x = 3 is our answer

The measure of the angle
miv72 [106K]
First, we know this diagram consists of two horizontal lines cut by a transversal line. Therefore, we know that the given angle that measures 113° and the angle we want to find are alternate interior angles. Since all alternate interior angles are equal, we know the unknown angle must also be 113°.

I hope this helps.

Please resolve this problem for me! I've been having trouble with this for a while.
Bad White [126]

Answer:

a) 41

b) -31

c) 25/3

Step-by-step explanation:

The instructions explain what a function is pretty clearly.

Basically, whatever is in the parentheses next to the f, you plug in to the expression that is the function.

ex:     f(x) = x + 4

        f(5) = 5 + 4 = 9

Okay, onto the problems:

a) f(x) = 3x - 1

First, plug in 14, since that is given:

f(14) = 3(14) - 1

and solve.

f(14) = 42 - 1

f(14) = 41

So, 41 is the answer to a.

b) Do the same thing you did in problem a. Plug in the number inside the parentheses and solve.

f(-10) = 3(-10) - 1

f(-10) = -30 - 1

f(-10) = -31

-31 is the answer to b.

c) For this problem, you have to do a bit of algebra.

First, take the base function f(x):

f(x) = 3x - 1

Then, set f(x) = 24:

24 = 3x - 1

and solve by isolating x.

25 = 3x

\dfrac{25}{3} = x

x = \dfrac{25}{3}

25/3 is the answer to c.

you deposited $5500 in a account that pays 3.6% annual interest. find the balance after 2 years if the interest is compound mont
Sedaia [141]

Answer:

$5,909.97

Step-by-step explanation:

We will use the compound interest formula for this problem as shown below:

A=P(1+\frac{r}{n} )^{nt}

<em>P = initial balance</em>

<em>r = interest rate (decimal)</em>

<em>n = number of times compounded annually</em>

<em>t = time</em>

<em />

First, change 3.6% into a decimal:

3.6% -> \frac{3.6}{100} -> 0.036

Now plug in the values:

A=5,500(1+\frac{0.036}{12})^{12(2)}

A=5,909.97

After 2 years, the balance would be $5,909.97
