18.75 minutes; 25 haircuts

Find the unit rate per minute:

5 hours = 300 minutes

300 minutes

16 haircuts

=  

18.75 minutes

1 haircut

 8 hours = 480 minutes

480 minutes

18.75 minutes per haircut

 25.6 haircuts

Round DOWN to 25 haircuts.

Can someone please help me find the slope of these equations please?!
anastassius [24]

Answer:

The slope of the 1st equation is 3/4.The reason why I say this is due to the fact that in the slope-intercept form y=mx+b mx represents the slope.Moreover, the second equation has a slope of 7/3 because its mx value is 7/3 therefore implying that it is the slope for equation number 2.Hope that helped.I dream of being brainliest.

Enter the value of w so the expression -5 +0.6W is equivalent to w (2.5 – 0.3w)​
NeX [460]

9514 1404 393

Answer:

  w = -2 or 8 1/3

Step-by-step explanation:

Setting the two expressions equal makes a quadratic equation:

  -5 +0.6w = w(2.5 -0.3w)

  0.3w^2 -1.9w -5 = 0 . . . . . . subtract the right-side expression

  3w^2 -19s -50 = 0 . . . . . . . multiply by 10 to give integer coefficients

  (3w -25)(w +2) = 0 . . . . . . . factor

We can use the zero product rule to find the solutions. The product will be zero only if a factor is zero.

  3w -25 = 0   ⇒   w = 25/3 = 8 1/3

  w +2 = 0   ⇒   w = -2

The values of w that make the two expressions equivalent are -2 and 8 1/3.

I'm stuck on C, please help. Thank you
jonny [76]

Step-by-step explanation:

(x {}^{4}  - x) {}^{4} -  ( {x}^{4}  - x)

x {}^{16}   +  4( {x}^{12} ) - x + 6( {x}^{8} )( {x}^{2} ) + 4( {x}^{4} )( -  {x}^{3} ) +  {x}^{4}  -(  {x}^{4}  - x)

{x}^{16}  - 4 {x}^{13}  + 6 {x}^{10}  - 4 {x}^{7}  +  {x}^{4}  -  {x}^{4}  + x

{x}^{16}  - 4x {}^{13}  + 6 {x}^{10} - 4 {x}^{7}   + x

andrew-mc [135]

Answer:

P(compact cars) = 4/25

Step-by-step explanation:

We know that there are 13 trucks, 8 vans, and 4 compact cars.

Let P denotes the probability of an event

Now we are asked to find the probability of compact cars

Number of favorable events = number of compact cars = 4

total number of outcomes = 13+8+4 = 25

hence, P(compact cars) = number of favorable events/total outcomes

                                       =4/25
