The answer is:  " $ 130.00 " ;  or, write as:  " $ 130 " .
_________________________________________________________
Explanation:
_________________________________________________________
                →     { $ 58.23  +  $ 66.57 } ;
_________________________________________________________
  →    Round EACH of these TWO (2) values to the nearest TEN (10) dollars ;
    {as per the instructions specified in THIS VERY "Brainly" question/ problem} ; 
_________________________________________________________
  →  Start with the first 'given value' :    →   " $ 58.23 "  ; 
_________________________________________________________
→  We are instructed to round to the nearest TEN (10) dollars ; 

→
 Do we round to:  "$ 50.00" ? ; or, to:  "$ 60.00" ?

→  Since the amount is:  " $ 58.23 " ; 

→ We look the value of the
"digit" that appears in the "space" DIRECTLY AFTER the:                            " ($5) " .   

                  →  If the [said digit] is:  "5 or greater" {i.e., "5, 6, 7, 8, or 9"} ;                     
                                                  then we round (up) to:  " $ 60.00 " .                                                          
                  →  If the [said digit] is:  "4 or lesser" {i.e., "4, 3, 2, 1, or 0") ; 
                                                  then we round (down) to:  " $ 50.00 " .

→ Since the [said digit] in the value, " $ 58.23" ; is:  "8" ;              

→ { and since:  "8" — is a [number/digit) that is:  "5 or greater" } ; 

→ We round (up) to:
  " $60.00 " .
__________________________________________________________
→  Now, let us consider the "second value" given to us:   →  " $ 66.57 " ; __________________________________________________________
→  We are instructed to round to the nearest TEN (10) dollars ; 

→  Do we round to:  " $ 60.00" ? ;  or,  to:  " $ 70.00"  ?

→  Since the amount is:  " $ 66.57 " ; 

→ We look the value of the
 "digit" that appears in the "space" DIRECTLY AFTER the:                            " ($6) " ;

                   →  If the [said digit] is:  "5 or greater" {i.e., "5, 6, 7, 8, or 9"} ;                      
                                                  then we round (up) to:  " $70.00 " .                                                          
                  →  If the [said digit] is:  "4 or lesser" {i.e., "4, 3, 2, 1, or 0") ;  
                                                  then we round (down) to:  " $60.00 " .
                                                        
.→ Since the [said digit] in the value, " $ 66.57 " ; is:  "6" ;              

 →  { and since:  "6" — is a [number/digit) that is:  "5 or greater" } ; 

 →  We round (up) to:  " $70.00 " .
._____________________________________________________
 →  So;  as per the instructions in this very "Brainly" question/problem  ; 
_____________________________________________________
We rewrite:   →  { $ 58.23  +  $ 66.57 } ;

   →  <u>by substituting</u>:  "$60.00" (in lieu of:  "$58.22") ;  <u><em>and</em></u>

   →  <u>by substituting</u>:  "$70.00" (in lieu of:  "$66.67") ;  
________________________________________________________
   →  as follows:
________________________________________________________
      →  { $60.00  +  $70.00 } ;

      →
and add these 2 (TWO) "rounded" values together; as follows:
________________________________________________________
      
→  { $ 60.00  +  $ 70.00 } ;   to get:  
________________________________________________________
        =  " $ 130.00 " ; or, write as:  " $ 130 " .

Anastaziya [24]
A] <span>A remote-control airplane descends at a rate of 2 feet per second. After 3 seconds it is 67 feet above the ground. 
the point slope equation will be given as follows:
y-y1=m(x-x1)
where:
slope,m=2 ft/sec
(x1,y1)=(3,67)
thus plugging in the values in the formula, we obtain the point slope equation as follow:
y-67=2(x-3)

Answer:
</span>y-67=2(x-3)

b]The height of the plane after 8 seconds will be:
x=8 sec
but:
y-67=2(x-3)
substituting x=8 we get:
y-67=2(8-3)
y-67=2(5)
y=10+67
y=77
thus the height after 8 seconds is 77 ft
