Answer:

-3c

Step-by-step explanation:

The given expression is:

\frac{\frac{6c^{2}+3c}{-4c+2}}{\frac{2c+1}{4c-2}}

We need to simplify this expression. The rational expression in the denominator can be multiplied to numerator by taking its reciprocal as shown below:

\frac{\frac{6c^{2}+3c}{-4c+2}}{\frac{2c+1}{4c-2}} \\\\ =\frac{6c^{2}+3c}{-4c+2} \times \frac{4c-2}{2c+1}\\\\=\frac{3c(2c+1)}{-(4c-2)} \times \frac{4c-2}{2c+1}\\\\ =-3c

Thus, the given expression in simplified form is equal to -3c

Answer:

-3c

Step-by-step explanation:

We are given that an expression

\frac{\frac{6c^2+3c}{-4c+2}}{\frac{2c+1}{4c-2}}

We have to find an expression which is equal to given  expression

Taking common 3c from nominator and -2 from denominator in dividened  and 2 common in divisor then we get

\frac{\frac{3c(2c+1)}{-2(c-2)}}{\frac{2c+1}{2(2c-1)}}

\frac{3c(2c+1)}{-2(2c-1)}\times \frac{2(2c-1)}{(2c+1)}

By reciprocal divisor

By canceling same factor

Then ,we get

\frac{\frac{6c^2+3c}{-4c+2}}{\frac{2c+1}{4c-2}}

=-3c

Brooke is located 5 miles out at sea from a straight shoreline in her kayak. She wants to make it to the taco truck on the beach
jenyasd209 [6]

Answer:

x  =  1,2909  ml   (point where Brooke beaches her kayack)

Step-by-step explanation:

I did not find the indicated picture.  I design one  (See picture in Annex)

The route to follow by Brooke  is  x₁   +  x₂ and as we need to express total time.

s  (distance)  =  velocity* time    then     time t  =  distance / velocity

x₁  = √ (5)² + x²        ⇒  x₁  = √( 25 + x² )

and   x₂   =  (  6  -  x  )

x₁  = distance in kayack     ( speed 2 ml/h)

x₂  = distance walking       ( speed  4 ml/h)

Then total time as a function of x is

t(x)   =  √( 25 + x² ) / 2     +   (  6  -  x  ) / 4

Taking derivatives on both sides of the equation we get

t´(x)   =  2x* (2) / 4 *√( 25 + x² )  - 1/4

t´(x)   =  0       2x* (2) / 4 *√( 25 + x² )  - 1/4  = 0      x/√( 25 + x² ) - 1/4  = 0

x/√( 25 + x² )  = 1/4

x    =   √( 25 + x² ) /4

x²   =  (25 + x² ) /16

16*x²   = 25  +  x²

15x²   =  25          x  =  1,2909  ml   (point where Brooke beaches her kayack)

Then  walking distance is   x₂   =  6  - 1.2909    x₂  = 4.71 ml

If we spin the spinner 10 times, what is the best prediction possible for the number of times it will land on yellow or purple?
kiruha [24]

Answer:

Yellow = 5 times and I think you meant blue since there is no purple so blue = 3 times

Step-by-step explanation:

There is ten in all and half of the spaces are yellow, or 50%. Out of ten times, you should land on it about half, or 5. For blue, there are 3 spaces, or 30%. Out of ten times, you should lamd on it about three.

What divided by 10² is 22.425
Ipatiy [6.2K]

Answer:

2,242.5

Step-by-step explanation:

10² = 100 (one and 2 zeros ; notice that the exponent is 2 )

Makes sense that we will need a bigger number than 22.425 to divide by 100 to get a 22.425 so move the decimal point to the left 2 spots and get 2,242.5.

2,242.5 /100 = 22.425
