Answer:
12
Step-by-step explanation:
Let x be the number of gallons of water in lake Mead.
Given that there is 326099 gallons in 1 acre-foot, we calculate Mead's gallons as:
![1 acrefoot=326099g\\28945000acrefoot=x\\\\x=\frac{28945000acrefoot\times326099g}{1acrefoot}\\\\x=9.4\times 10^{12} \ gallons](https://tex.z-dn.net/?f=1%20acrefoot%3D326099g%5C%5C28945000acrefoot%3Dx%5C%5C%5C%5Cx%3D%5Cfrac%7B28945000acrefoot%5Ctimes326099g%7D%7B1acrefoot%7D%5C%5C%5C%5Cx%3D9.4%5Ctimes%2010%5E%7B12%7D%20%5C%20gallons)
We now equate x to
;
![9.4\times 10^a=9.4\times 10^{12}\\\\a=12](https://tex.z-dn.net/?f=9.4%5Ctimes%2010%5Ea%3D9.4%5Ctimes%2010%5E%7B12%7D%5C%5C%5C%5Ca%3D12)
Hence, a=12
Answer: 3x^2 + 5x + 4
Step-by-step explanation:
The expression for the height of the rectangle is found by dividing the expression for the area, 3x3 − x2 − 6x − 8, by the expression for the base, x − 2. Use synthetic division.
2 hours and 37 minutes is 2x60+37 = 157 minutes so to get the answer subtract
157-72=85 so there was not 85 minutes or 1 hour and 25 minutes of childrens video
Guppies . . . . 1 time
Tetras . . . . . 11 times
Sum of fish. . . . . 12 times
Number of fish . . 48
12 times = 48
Divide each side of the equation by 12 :
1 time = 4
Guppies = 1 time =<em> 4 guppies</em>
Tetras = 11 times = 11 x 4 = <em>44 tetras</em>
Total fish = 4 + 44 = 48 yay !
