what is the unit price of 16 and 12.29, 32 and 19.98, and 128 and 34.99 (it would be really helpful to know thanks) show work

SpyIntel [72]

Answer:

The unit costs are $0.77, $0.62 and $0.27 respectively.

Step-by-step explanation:

The unit price is simply the cost of the items divided by the amount of the items that are included. So, just take the cost and divide it.

$12.29/16 = $0.77 per unit

$19.98/32 = $0.62 per unit

$34.99/128 = $0.27 per unit

You have decided to purchase a new Toyota 4Runner for $25,635. You have promised your daughter that the SUV will be hers when th

Ok so our two variables will be:

x=age y=price

Our equation is:

y= -3000x + $25,635

Alecsey [184]

So what you want to do is do long division (using 32.000 divided by 1243.12). You should get this answer:

Can I have help with the question

sleet_krkn [62]

Answer:

Midpoint = (3.5, 4.5)

Perpendicular bisector = y = $\frac{7}{9}$ x + $\frac{16}{9}$

Step-by-step explanation:

[] We can solve this using the midpoint formula:

-> See attached

[] Plug-in our coordinates and solve:

$(\frac{7+0}{2} ,\frac{0+9}{2} )=(\frac{7}{2} ,\frac{9}{2} )=(3.5,4.5 )$

[] Now we will find the slope to solve for the perpendicular bisector.

-> We will use slope-intercept form, see attached

$\frac{9-0}{0-7}=\frac{9}{-7}$

-> The slopes of two perpendicular lines are negative reciprocals of each other, so $\frac{7}{9}$ will be the slope of or perpendicular bisector

-> Now we can solve for the equation by using y – y1 = m ( x – x1), were y1 and x1 are the coordinates of our midpoint

y - 4.5 = $\frac{7}{9}$ (x-3.5)

y - 4.5 = $\frac{7}{9}$ x- $\frac{49}{18}$

y = $\frac{7}{9}$ x- $\frac{49}{18}$ + 4.5

y = $\frac{7}{9}$ x + $\frac{16}{9}$

Have a nice day!

I hope this is what you are looking for, but if not - comment! I will edit and update my answer accordingly. (ノ^∇^)
