Answer:
20.5 or 20 1/2
Step-by-step explanation:
calculator -.-
So supplementary is an 180 angle and complimentary is 90 degree angle so that being said I could be wrong but that looks like a complimentary so a 90 degree angle it’s a 90 degree
Answer:
2 seconds
Step-by-step explanation:
You could set 3t + 16t^2 = 70 and solve for t.
OR
You could plot it on Desmos.
This is an incomplete question, here is a complete question.
A hurricane wind blows across a 7.00 m × 12.0 m flat roof at a speed of 150 km/h.
What is the pressure difference Δp = p(inside)-p(outside)? Use 1.28 kg/m³ for the density of air. Treat the air as an ideal fluid obeying Bernoulli's equation.
Answer : The pressure difference will be, 
Step-by-step explanation :
As we are given:
Speed = 150 km/h = 41.66 m/s
Density = 
Area = A = 7.00 m × 12.0 m
Formula used :

Now put all the given values in this formula, we get:


Thus, the pressure difference will be, 
Answer:
3/70
Step-by-step explanation:
change 1/10 and 1/7 so the denominator (bottom number) is the same. 1/10= 7/70 and 1/7= 10/70 so you need 3/70 to make the two numbers equal.
