Answer:
Step-by-step explanation:
The rate of change of the radius dr/dt = . 75 in/min because the radius is increasing with respect to time. hence, the volume is increasing at a rate of 75π cu in/min when the radius has a length of 5 inches.
Answer:
15 lb
Step-by-step explanation:
let the current weight of the puppy be X, the initial weight of the puppy is 4lb or
, (6 lb less 2/3 X) .
#We equate the current weight to the initial weight to determine X:
![4\ lb=\frac{2}{3}X-6\ lb\\\\10 \ lb=\frac{2}{3}X\\\\X=15](https://tex.z-dn.net/?f=4%5C%20lb%3D%5Cfrac%7B2%7D%7B3%7DX-6%5C%20lb%5C%5C%5C%5C10%20%5C%20lb%3D%5Cfrac%7B2%7D%7B3%7DX%5C%5C%5C%5CX%3D15)
Hence, the current weight of the puppy is 15 lb
Answer:
114.75
Step-by-step explanation:
- 6x3=18
- 8x10=80
- 8.5
- Add all together, you get = 229.5
- Divided by 2 you get = 114.75
Simplify terms, then move the terms over so 'y' is by itself.
-7y-0.6=3.6-y
-0.6-3.6=-y+7y
-4.2=6y
y=-4.2/6
y= -0.7
