Nine days. You can divide 108 by 36, to get how many times she has to read 36 pages, which is 3. Then you multiply that by 3, because she uses 3days for every 36 pages. 3x3=9
Answer:
Step-by-step explanation:
The given function is
![y=\sqrt[3]{x+8}](https://tex.z-dn.net/?f=y%3D%5Csqrt%5B3%5D%7Bx%2B8%7D)
The range refers to the values of y for which x is defined.
We solve for x to obtain;
This is a polynomial function in y.
x is defined for all values of y.
Therefore the range is all real numbers.
or
The first choice is correct.
Answer:
6 ounces
Step-by-step explanation:
Let x = the number of ounces of the 15% alcohol solution needed to be mixed with the 4 ounces of 20% alcohol solution to obtain the 17% alcohol solution.
After converting the percentages to their decimal equivalents, set up the necessary equation as follows:
0.15x+0.20(4) = (x+4)(0.17) Simplify and solve for x.
0.15x+0.8 = 0.17x+0.68 Subtract 0.15x from both sides.
0.8 = 0.02x+0.68 Now subtract 0.68 from both sides.
0.12 = 0.02x Finally, divide both sides by 0.02
x = 6
You need to mix 6 ounces of 15% alcohol solution with 4 ounces of 20% alcohol solution to obtain 10 (x+4)ounces of 17% alcohol solution.
