Move 12 to the other side, making it negative
h=31-12
h=19
Answer:
Question 1 Answer : x^2 - 2y^2
Question 2 Answer: x^2
- 36
I believe the correct given problem is:
“What is 80% in its simplest form as a fraction?”
Take note that you missed to place the percent sign which
is very important.
Now to solve this, 80% when converted to decimal form is
0.80 which means that you have 80 parts per 100 parts. Therefore the fraction
form of this would be 80 / 100.
fraction = 80 / 100
However this fraction is not yet the answer because we
can still simplify this further. First step in simplifying is to divide both
the numerator and denominator by 10 so that we are left with:
8 / 10
Next step is to divide by 2:
4 / 5
Now we can see that we can no longer divide this (numbers
should be whole number). Therefore the simplest form as a fraction is 4/5
Answer:
4/5
U= 9.4m/s
v= -7.4m/s (Negative sign because it is in the opposite direction as he is rolling back)
t= ?
s= ?
a= ?
Now, a= v-u/t
= -7.4-9.4÷3
=-5.6
By the second equation of motion.
s= ut+1÷2at*2 ( *2 is the power)
s= 9.4×3+1÷2×-5.6×3*2
= 28.2 +(-25.2)
=3
Therefore s or the distance travelled is 3m.
