The value of pi is 3. the mathematics archimedes believed that pi was between 3 1/7 3and 3 10/71 .was archimedes correct

Yes, Archimedes was correct.

Step-by-step explanation:

Archimedes, the famed Greek and genius mathematician, inventor, and engineer (among other names), evaluated that the value of Pi was between 3 10/71  and 3 1/7ths.

The value of Pi that matter at this particular moment is 3.1415.

Calculate what 3 and 10/71ths is.

3 10/71= 3.1408

Calculate what 3 and 1/7ths is.

3 1/7= 3.1428

Pi does, in fact, fall between these two numbers.

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.

10/60

step-by-step explanation:

if you divide 10 by 60 the answer is 0.166666 while if you divide or solve the other problems it equals 0.6
