Find all values of c such that c/(c - 5) = 4/(c - 4). If you find more than one solution, then list the solutions you find separ

Deffense [45]

Answer:

$\large\boxed{\bold{NO\ REAL\ SOLUTIONS}}\\\boxed{x=4-2i,\ x=4+2i}$

Step-by-step explanation:

$Domain:\\c-4\neq0\ \wedge\ c-5\neq0\Rightarrow c\neq4\ \wedge\ c\neq5\\\\\dfrac{c}{c-5}=\dfrac{4}{c-4}\qquad\text{cross multiply}\\\\c(c-4)=4(c-5)\qquad\text{use the distributive property}\\\\c^2-4c=4c-20\qquad\text{subtract}\ 4c\ \text{from both sides}\\\\c^2-8c=-20\qquad\text{add 20 to both sides}\\\\c^2-8c+20=0\qquad\text{use the quadratic formula}$

$\text{for}\ ax^2+bx+c=0\\\\\text{if}\ b^2-4ac0,\ \text{then the equation has two solutions}\ x=\dfrac{-b\pm\sqrt{b^2-4ac}}{2a}$

$x^2-8x+20=0\\\\a=1,\ b=-8,\ c=20\\\\b^2-4ac=(-8)^2-4(1)(20)=64-80=-16$

$\text{In the set of complex numbers:}\\\\i=\sqrt{-1}\\\\\text{therefore}\ \sqrt{b^2-4ac}=\sqrt{-16}=\sqrt{(16)(-1)}=\sqrt{16}\cdot\sqrt{-1}=4i\\\\x=\dfrac{-(-8)\pm4i}{2(1)}=\dfrac{8\pm4i}{2}=\dfrac{8}{2}\pm\dfrac{4i}{2}=4\pm2i$

Some liquid will be poured from a 16 ounce container until it is filled to the percent of the the larger container (87.5%).How m

4vir4ik [10]

Answer:

16 ounces

Step-by-step explanation:

First we are told that a container has a capacity of 16 ounces of liquid and therefore 16 ounces of liquid can fill that one container

The 16 ounces liquid from the 16 ounce container is fully emptied in a larger container and fills 87.5% of the larger container therefore the larger container is:

100/87.5×16 ounces= 18.285 ounces in liquid capacity

Therefore to fill the smaller 16 ounce container, the larger container would have to pour 16 ounces of liquid into the smaller container, and would would still have 18.285-16=2.285 ounces if it(the larger container) were filled to the brim(100%)

Answer:

The third one from left to right

Step-by-step explanation:

Just check that when x = 11

y= $-\sqrt[3]{11-3}+4=-2+4=2$

So the graph passes through the point (11,2)

Sheri built a 1/200 scale model of a dam. She used 0.1 cubic meter of plaster. What is the volume of the actual dam in cubic met

Fynjy0 [20]

The correct answer is C) 800,000 cubic meters.

The scale given is for the length, width or height of the model. In order to find the scale for the volume, we would cube this scale, since volume is a cubic measurement:
(1/200)³ = 1/8,000,000

Since the volume of the model is 0.1, we multiply this by 8,000,000 to find the volume of the actual dam:
0.1(8000000) = 800,000

Jerry had 1 gallon of ice cream. He used 4/10 gallon to make chocolate milkshake and 0.30 gallon to make vanilla milkshake. How

stiv31 [10]

0.30 is the same as 3/10 so then you would add 3/10 and 4/10 which equals 7/10 which then gives you with 3/10 ice cream left
