Answer:
28 minutes
Step-by-step explanation:
we know that
1) A factory manufactures a metal piece in 32 minutes
2) New technology allowed the factory to cut that time by 8%
Remember that
In this part 32 minutes represent the 100%
To find out how long it take to manufacture the piece, multiply 32 minutes by the factor 0.92
3) Then another improvement cut the time by 5%
Remember that
In this part 29.44 minutes represent the 100%
To find out how long it take to manufacture the piece now, multiply 29.44 minutes by the factor 0.95
1 can be interpreted as a "whole" thing, and smaller than 1 is a part of a thing.
imagine: if you have some cakes and you count the number of cake pieces, those will be more than the number of cakes: as each cake will have more than one piece! (otherwise it wouldn't be called a piece!)
so the result of a division by a fraction is bigger than the original number, there are more parts than wholes in the results, as each whole has multiple parts!
for example: divide 3 cakes into pieces which are 1/4th of a cake. how many such pieces would there be? 12! more than the 3 original cakes;
is this possible to understand? tell me if not!
Answer:
4 / 20 (1 / 5)
20%
Step-by-step explanation:
The experimental probability is what actually happens in an experiment (as opposed to an authentic probability calculated from genetics).
In this experiment, there are 3 outcomes with :
3 tails and 1 head
(tails represent female, head represent male)
So, 4 / 20 of the time, this coin flip was what we call a "success" (meaning that it matches the guidelines that we want)
4 / 20 = 20% of the time
So, the probability of a group of 4 puppies being 3 females and 1 male is :
4 / 20 (1 / 5)
20%
Answer: √58 cm or 7.62 cm
Step-by-step explanation:
The Pythagorean Theorem is a²+b²=c². Since we are given the lengths of a and b, we can plug them into this formula to find the length of the hypotenuse.
7²+3²=c²
49+9=c²
58=c²
c=√58 or 7.62 cm
