Answer: 10.2 meters per hour; or, write as: 10 ⅕ meters per hour.
___________________________________________
Explanation:
_____________________________________
Note: "h" = time in "hour(s)" ;
"cm" = length in "centimeter(s)" ;
"min" = time in "minute(s)";
"m" = length in "meter(s)"
_____________________________________
Note these EXACT conversions:
_________________________________
100 cm = 1 m ;
60 min = 1 h ;
_________________________________
To solve:
Given: 17 cm / min ; convert to: ________ m / h
__________________________________________________
(17 cm / min)* (1 m /100cm) * (60 min / 1 h) = _______ m / h
__________________________________________________
The "cm" units cancel to "1"; the "min" units cancel to "1" and we are left with units of "m/h" {"meters per hour"}.
___________________________________
We are left with (17 *1 m * 60) / (100 * 1 h) = [(17 * 60) m] / [100 h]
= [(17 *60) / 100 ] meters per hour.
________________________________________________________
To simply: (17 * 60) / 100 ;
_________________________
Method 1): To simplify: (17 * 60) / 100 ;
→Rewrite as: (17*60) / 100 = (17*20*3)/(20*5) ;
→Cancel out the "20's "; and rewrite as:
→ (17*60) / 100 = (17*3)/5 = 51/5
= 10.2 meters per hour; or, write as: 10 ⅕ meters per hour.
________________________________________________________
Method 2) To simplify: (17 * 60) / 100 ; Use calculator (or by hand):
___________________________________
→ (17 * 60) / 100 = 1,020 /100
= 10.2 meters per hour; or, write as: 10 ⅕ meters per hour.
__________________________________
Method 3) To simplify: (17 * 60) / 100 ;
_____________________________________
→ (17 * 60) / 100 = ? ;
→ Divide BOTH the "100" AND the "60" by "10";
→ 60÷10 = 6 ; 100÷10 =10; and rewrite—replace the "60" with a "6"; and replace the "100" with a "10" ;
____________________________
→ (17*60)/100 = (17*6)/10 = 102/10
= 10.2 meters per hours; or, write as: 10 ⅕ meters per hour.

Answer:
7/9
Step-by-step explanation:
Answer:
y = 16
Step-by-step explanation:
y = 11 - x
of x is -5, subtitute it into the equation
y = 11 - (-5)
y = 11 + 5
y = 16
Answer:
1 / 10 (1 : 10) (10%) - your teacher has probably given you some idea as to the formatting of how you should write probability [so 3 different ways are written here], but I suspect they expect you to write it as 1 / 10
Step-by-step explanation:
only 1 out of all of these 10 trials is a "success" (aka what we are looking for)
we know that 7 matches the criteria of all years seeing a groundhog, and that all other options (1 , 2 , 3 , 4 , 5 , 6 , 8 , 9 , 10) do not meet this criteria.
so, the experimental probability** is 1 / 10 (or 1 : 10) (1 / 10 = 10%)
**: experimental probability is about how many times something happens in the experiment--not theoretically. it means that if his life was destined to be 1 of the 10, the probability of his experience matching the criteria is 1 / 10
experimental probability can be thought of as
successes / possible outcomes
