-1 3/4 = -1.75
1/9 x 100% = 1 divided by 9 times 100 = 11.11%
First, there are FOUR significant digits in your question, so the sci notation should have 4 significant digits too:
1.325 x 10^(-2)
7/25 = 7 divided by 25 using a calculator results in 0.28
Roberto's distance at time 't' = 30 + 30 t (the 30 is the headstart he got by going one hour earlier)
His parents distance is 45 t
When are they equal?
30 + 30t = 45t
30 = 15t
t = 2 hours after 12 o'clock Roberto traveled 90 miles, his parents traveled 90 miles (this will be 3 hours after Roberto leaves.....and only two hours after his parents leave)
The alphabet doesn't have any numbers, so there can be no 'best number of the alphabet' .
7/3 is 'Seven thirds' is the same as 7 divided by 3 is the same as 2 1/3 is the same as 2.333333....
98/4kg = 24.5/kg
The number of hits is given by f(x)
The numbers of HITS are given as 4 12 14 27 42
f(x) = 4 = x-11 solve for 'x' x = 15 PITCHES
f(x) = 12 = x-11 x = 23 pitches
etc
etc......Then add all of the pitches....
Let 'x' be the integer
x+2 is the next integer
x+4 is the third integer
They all add to 126
x + x+2 + x+4 = 126
3x +6 = 126
3x=120
x=40
