What is x divided by x-1 - 1 divided by 2-2x expessed as a single fraction ?

Kay [80]

To simplify into 1 fraction, remember, we must make the denominator the same
x/ (x-1 ) - 1/ (2-2x)
= -x/ -(1-x) - 1/(2-2x) [see the similarity now? ] [whatever we multiply for the denominator, as long as we multiply to the numerator, it will be ok]
= -2x / -(2-2x) + 1/-(2-2x)
= (-2x+1 )/ -(2-2x)
=(2x-1)/(2-2x)

2. Carissa also has a sink that is shaped like a half-sphere. The sink has a volume of 3617 in? One day, her

Juliette [100K]

Answer:

863 cups

Step-by-step explanation:

step 1

Find the volume of the conical cup

The volume of the cone (cup) is equal to

$V=\frac{1}{3}\pi r^{2}h$

we have

$r=2/2=1\ in$ ----> the radius is half the diameter

$h=4\ in$

assume

$\pi =3.14$

substitute

$V=\frac{1}{3}(3.14)(1^{2})4=4.19\ in^3$

step 2

Find out how many cups of water must Carissa scoop out of the sink

Divide the volume of the sink by the volume of the cup

so

$\frac{3,617}{4.19}= 863\ cups$

Mkey [24]

Answer:

A. $\frac{1}{4}$ = $\frac{3}{12}$

Step-by-step explanation:

$\frac{1}{4}$ of the students wore shorts.

$\frac{3}{12}$ of the students wore jeans.

Converting the fractions of the students who wore shorts and jeans respectively;

$\frac{1}{4}$ = 0.25

$\frac{3}{12}$ = 0.25

This means that the ratio of students who wore shorts is the same as that of students who wore jeans.

i.e $\frac{1}{4}$ = $\frac{3}{12}$

sattari [20]

Answer:

From the attached graphic we see that

rhombus side = Sqr Root [(Long Diagonal / 2) ^ 2 + (Short Diagonal / 2) ^ 2]

rhombus side = Sqr Root [(24/2)^2 + (18/2)^2]

rhombus side = Sqr Root [144 + 81]

rhombus side = Sqr Root (225)

rhombus side = 15 feet
