Answer:
x=24
Step-by-step explanation:
x=√(26)²-(10)²
x=√676-100
x=√576
x=24
Answer:
4 litres of 12% solution
2 litre of 24% solution
Step-by-step explanation:
Let the 12% solution = l
Let the 24% solution = h
Dimitri needs a total of 6 litres of both :
l + h = 6 - - - - - - - - (1)
He needs a mixture of both volumes of both to give a 16% volume
12%l + 24%h = 16% * 6
0.12l + 0.24h = 0.96 ----(2)
From (1)
l + h = 6;
l = 6 - h
Substitute l =6-h into (2)
0.12(6 - h) + 0.24h = 0.96
0.72 - 0.12h + 0.24h = 0.96
0.72 + 0.12h = 0.96
0.12h = 0.96 - 0.72
0.12h = 0.24
h = 0.24 / 0.12
h = 2
From ;
l = 6 - h
l = 6 - 2
l = 4
Answer: Peter < 65
Step-by-step explanation: Peter has less than charlie so charlie is more than or/and equal to being solid line underneath or solid line on graph represented by ≥ 65 stays equal to 65 or more which is a<em> correct statement</em> for charlie as charlie cards are<em> increasing </em>at 65 and has 65 and Peter is shown as ≤ 65 but is slightly wrong as we were told in question that 'he has just started collecting' this means it has to be or certainly less than charlie has - Just in diagram is interpreted as a <em>dotted line on graph coordinates</em><em> </em>represented by < 65<em> instead IS LESS THAN 65</em> would be correct way to interprete inequality of<em> Peters relationship value </em>to that of charlie given amount
