The Answer fam is (1/4,7/8)
Answer: 55
Step-by-step explanation:
90+35=125
180 is the total degrees of an angle so 180-125= 55
Answer:
If `r` and `R` and the respective radii of the smaller and the bigger semi-circles then the area of the shaded portion in the given figure is: (FIGURE) `pir^2\ s qdotu n i t s` (b) `piR^2-pir^2\ s qdotu n i t s` (c) `piR^2+pir^2\ s qdotu n i t s` (d) `piR^2\ s qdotu n i t s`
Step-by-step explanation:
Answer:
First, I think the right formula is:
![V(t) = 100,000(1-\frac{t}{60} ),20\leq t\leq 60](https://tex.z-dn.net/?f=V%28t%29%20%3D%20100%2C000%281-%5Cfrac%7Bt%7D%7B60%7D%20%29%2C20%5Cleq%20t%5Cleq%2060)
A) We first derive the formula given above:
![V'(t)=-\frac{100000}{60}](https://tex.z-dn.net/?f=V%27%28t%29%3D-%5Cfrac%7B100000%7D%7B60%7D)
V'(t) represent the drain rate of the tank volume.
B) the units is: gallons/time
C) at V'(10) = 100000/60 = 1666.66 gallons/time.
because the formula V'(t) is constant so it doesn't depend of time.
