Answer:

i hope this helps

Step-by-step explanation:

if you have 100 people in the room and you interviewed all of them, (for number 6). that means that 70% of these people ate breakfast

70% of the total amount of people you interviewed is 70. That means that 70 people you interviewed, eat breakfast.

Then it also says, "of those 70% of people, 25% eat cereal"

That means 25% of those 70 people eat cereal, or 1/4 of that population does.

0.25 * 70 = 17.5. (of course you cannot have part of a person, but this is an example)

and of the 17.5 people, 30% of them eats it with extra sugar.

so 30% of 17.5 people is 5.25.

that means that there are 5.25 people who eat cereal with extra sugar.

i hope this helps, it took a while for me to try to help with this

i noticed that you made a mistake. the amount of people that eat cereal is 25% of 70% of the people. that means you have to find 0.25 of 0.7 <--- (you multiply not divide)

(0.25x 0.7) = 0.175

Solve for<br> a. 7a-2b = 5a b

Nookie1986 [14]

For this case we have the following expression:

$7a-2b = 5ab$

From here, we must clear the value of a.

We then have the following steps:

Place the terms that depend on a on the same side of the equation:

$7a - 5ab = 2b$

Do common factor "a":

$a (7 - 5b) = 2b$

Clear the value of "a" by dividing the factor within the parenthesis:

$a =\frac{2b}{7-5b}$

Answer:

The clear expression for "a" is given by:

$a =\frac{2b}{7-5b}$

What is the y-intercept of the quadratic function f(x) = (x – 8)(x + 3)? (8,0) (0,3) (0,–24) (–5,0)

DiKsa [7]

The correct answer is: [C]:  " (0, 24) " .
___________________________________________________________

Explanation:
___________________________________________________________

Given the quadratic function:
___________________________________________________________

→ " y = (x <span>− 8) (x + 3) " ;   </span>← Note: Replace the "f(x)" with: "y" ;

→ Find the "y-intercept".
___________________________________________________________

→ Note: The "y-intercept" is the coordinate of the point(s) of the graph of the equation at which the graph crosses the "x-axis" when "x = 0" .

→ So; we set plug in "0" for "x" into our equation; and solve for "y" ;

  → " y = (x − 8) (x + 3) " ;

  →   y = (0 − 8) (0 + 3) ;

  → y = (-8) * (3) ;

  → y = - 24 ;
___________________________________________________________

So, the "y -intercept" of the <em><u>given</u></em> quadratic function is:

the point at which: "x = 0 ; y = -24 " ;

→ that is; the point the coordinates:  " (0, - 24) " ;
___________________________________________________________
→ which is: Answer choice: [C]: " (0, - 24) " .

What is the value of x when Rq=3x+2 ,QN =2x and SM=3x?

Andru [333]

The value of x is 2 because the centroid of the triangle divides each median in the ratio of 2:1 option (C) is correct.

<h3>What is the triangle?</h3>

The triangle can be defined as a three-sided polygon in geometry, and it consists of three vertices and three edges. The sum of all the angles inside the triangle is 180°.

The question is incomplete.

The complete question is in the picture, please refer to the attached picture.

We have:

RQ = 3x+2 ,QN = 2x and SM=3x

In the figure, the TM, Rn, and SL are medians of the triangle SRT and Q is the centroid.

The centroid of the triangle divides each median in the ratio 2:1

RQ/QN = 2/1

(3x+2)/2x = 2/1

After solving:

3x + 2 = 4x

x = 2

Thus, the value of x is 2 because the centroid of the triangle divides each median in the ratio of 2:1 option (C) is correct.
