For a problem like this, we have to think logically
we know that 6 * some number in the thousands must equal 25 thousand something. Let's say we put 5 in that first spot, 6 * 5,000 is already 30,000 so that's wrong. If we go one lower, 6 * 4,000 is 24,000 and so now we can include the 287 knowing it will fit.
so 6 * 4287 = 25,722.
all we do now is fill in the blanks to match our answer.
Answer:
Less than 90 degrees
Step-by-step explanation:If it were equal to 90 degrees it could make a perfect square as the angle and if its more it would be open wide i guess im a bad explainer sorry
The answer is 0.56
think of this like
14x = 25
to find x, divide 14 by 25
which will give you 0.56
to check your answer, you can just do 25 * 0.56
Answer:
B) 36 ft
Step-by-step explanation:
Given:
The height as a function of time is given as:
At maximum height, the instantaneous velocity becomes 0. The instantaneous velocity is the first derivative of the height function.
So, the derivative of the the given function is 0 at the maximum height.
Differentiating the above function with time, we get
Now, equating the derivative to 0 and finding time.
Therefore, time taken to reach maximum height is 1.5 s.
Now, maximum height is obtained by plugging in 
in the height equation.
Maximum height is given as:
Pump A = 45 mins
Pump B = 35 mins
Pump A and B = (45 x 35) / ( 45 + 35) = 19.69 mins (nearest hundredth)
-
Answer: 19.69 mins
