st ten dollars so Over a two month period Mr Bryants sixth grade class donated their spare change to help another student whose home burned. The class raised $58.23 the first month and $66.57 the second month about how much money did Mr. Bryants class raise for their classmate
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 toround 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 " . ________________________________________________________
Her answer is wrong because she the object cannot hit the ground at negative seconds. She could’ve have used other methods because she used the quadratic formula. The advantages is that it works for every situation. The disadvantages is that it takes longer. She should’ve used a different method.
