Answer:
His normal heart rate is 50 beats per minute.
Step-by-step explanation:
Since when it is hibernating it beats 10 times per minute and that is 20 % of the normal volume we can use a rule of 3 to find his normal herat rate. If 10 times per minutes is 20% of its normal volume then x times per minutes is 100%. So we have:
10 -> 20%
x -> 100%
10/x = 20/100
20x = 1000
x = 50 beats per minute
Answer:55
Step-by-step explanation:
So the question is 16 is 25% of what number (x)
In math
"is" means equals
"of" means times
The question translates to
16 = 25% * x
16 = .25x
16/.25 = x
64 = x
x = 64
16 is 25% of 64
You see that
.
This rule gives you an oportunity to state that 
. Therefore, 
. Multiplying function f(x) by factor 1/2 you obtain function g(x) that is compression function f(x) in the y-direction.
Answer: compression function f(x) in the y-direction by factor 1/2.
