Assume that a function named swapdoubles has been defined and is available for use in this exercise: that function receives two variables of type double and exchanges their values . write the definition of a function named sort3 that is passed three double variables . the function returns nothing but modifies the values of these variables so they are in sorted order. so, if a, b and c have (respectively) the values 3.14, 2.71, and 3.04, and the invocation sort3(a, b,c) is made, then upon return, the values of a, b and c will be 2.71, 3.04, and 3.14 respectively.
void sort3 (double & a, double & b, double & c){
if (a> b) swapdoubles (a, b);

if (b> c) swapdoubles (b, c);

if (a> b) swapdoubles (a, b);
}

let soccer = x and golf = y

part a

1st equation: x + y = 125

2nd equation: x = y +45

part b

replace x in the 1st equation with the 2nd one:

y + 45 + y = 125

simplify:

2y + 45 = 125

subtract 45 from each side:

2y = 80

divide both sides by 2:

y = 80/2

y = 40

she plays golf for 40 minutes.

part c

no because she plays soccer for 45 minutes longer than golf 40 +45 =   85 minutes, not 80 minutes.

hi! i think the answer is 1/2 : )

$4034.40

the perimeter of the field is the sum of the lengths of the four sides:

47 yd + 158 yd + 47 yd + 158 yd = 410 yd

the cost of 3 ft (1 yd) of fence is 3×$3.28 = $9.84.

so the cost of jake's wood perimeter fance is

(410 yd) × ($9.84 /yd) = $4034.40

the k side
