Answer:
Re= 5*10^5
Step-by-step explanation:
The numbers are not totally clear as they repeat each other. Under this consideration I will assume the closest values according to the advertised.
r=0.5m
V=1m/s (or) V=11m/s
We know that Reynolds number is given by,
Or for the another velocity
In reality, all of them are parallel to y=3x-8.
To find the one that crosses (4,-5) you will probably have to substitute 
for 4 in all formulas and check if 
.
Work done:
The only option that gave us an equality was B. Therefore, B. is the answer.
First, find 20% of 5 hours. 20% is also 1/5 of something, and 1/5 of 5 is 1.
Multiply 5 by 3 for the 300%, getting 15 hours, and add 1 for the 20%.
He spent 16 hours on the project. Hope this helps!
Answer:
maybe the second equation i.e(10+1.2)x=24
Answer:
never because you're multiplying the number -2 times so it will be positive only if the variable is positive.
Step-by-step explanation:
what if x=2?
2^-2
=
1
/2*2
=
1
/2^2
=
1
/4 or 0.25
what if x=-5?
-5^-2
=−1*5−2
=−1* 1
/5*5
=
−1
/5*5
=
−1
/5^2
=
−1
/25 or-0.04
