The y-intercept is the starting point. Since the temperature started at -7, we know that b in y = mx + b has to be -7. m is the slope which in our case is 3 because the temperature is changing every hour. So, because the temperature is going up, it's +3. Our equation should be y = 3x - 7.

What percent of 20 is 6
Luba_88 [7]

Answer:  30 percent of 20 is 6.

_______________________________________________

Step-by-step explanation:

_______________________________________________

(n/100)  * 20 = 6  ?  

Solve for "n"  .

_______________________________________________

Divide each side of the equation by "20" :

{ (n/100) * 20 }  / 20  = 6 / 20 ;

to get:

n/100  = 6/20 ;  

↔ 6/20 = n/100 ; solve for "n" ;

Look at the denominators:


20 * ? = 100 ?

  100/ 20 = ?  ;

  100/20 = 5 ;


So, 20 *  " 5" = 100 ;

Then 6* 5 = "n"  (for the numerator, "n";  in  :   "n /100" ) ;

                  →  6 * 5 = 30 ;

                  →  n = 30 .

 Answer:  30 percent of 20 is 6.

A rectangle is divided into 4 equal rows with 4 squares in each row. Mark says 1 square is 1/4
victus00 [196]

Answer:

A(s) = 1/16 square units

Step-by-step explanation:

Neither of them are correct

If we have a rectangle,  and divide  into 4 equals rows    ( by means of three horizontal lines ) we will get 4 rectangles each of which have 1/4 of total area. If after that we get 4 squares in each row the area of each of these squares is 1/4 of the area we got when dividing the rectangle with our three lines of the first case, therefore the area of each final square is:

A(s) = (1/4)/(1/4)

A(s) = 1/16 square units
