Answer:
Kawaii, the problem is the comparison with the calculated time for Jillian and the actual time for Jillian to run the 7 miles.
%error=(calculated value - experiemental value)/calculated * 100%
%error=(95-80)/95*100%=15/95 *100% = 15.79 ≈ 16% error
Note: 16% error is the approximate error because the numbers have 2 significant figures stated in the problem.
Step-by-step explanation:
i asked a expert on google
8500 you make two fractions set equal to eachother.. 6290/x (x is the missing number) and 74/100 (the percentage) you cross multiply the 6290 and 100 which is 629000 and divide it by the 74 which is 8500 which should be your answer
24. (2x+2)+(2x+2)+(2x+2)=(x+8)+(x+8)+(x+8)+(x+8)
6x+6=4x+32
-6 -6
6x=4x+26
-4x -4x
2x/2=26/2
x=13
Answer:
2/3 =x
Step-by-step explanation:
2/x = 6/2
Simplify 6/2 =3
2/x = 3
Multiply each side by x
2/x *x = 3*x
2 = 3x
Divide each side by 3
2/3 = 3x/3
2/3 =x
