Can someone help me please
Anarel [89]

Answer:

Step-by-step explanation:

I made a table with a pretend number of years of teaching by picking a somewhat random number to start

"Clark has less seniority than Cornwall but more than Prendergast:"  I picked 3 for Clark 4 for Cornwall, and 2 for Prendergast, to start.

"Prendergast has more than Brown but less than Alexander:"  I see I'm running out of easy numbers here.  "Prendergast has more than Brown" means give Brown 1 year but this new teacher, Alexander needs a number between Clark and Prendergast.  To make room, I increased Clark and Cornwall by 1 and finished the remainder in the "Final Years" column:

<u>Teacher </u>     <u>Years</u>     <u> Final Years</u>

Clark         3               4

Cornwall         4               5

Prendergast                  2    

Brown                          1

Alexander                  3

The highest seniority teacher, Cornwall, is smart and refuses the job.  That leaves Clark, at number 2 seniority, to become the new supervisor.

What is the point slope form of the line with slope 25 that passes through the point (−4,−7)?
slava [35]

Answer:

y+7=25(x+4)

Step-by-step explanation:

It is + because remember two - - negatives make a positive +. And the original formula is like this y-y=m(x-x), then m represents the slope, so your slope will always go in place of the m. And you can number the it y one - y two = m (x one - x two) if that helps. Hope it did help!!!

A cone has a diameter of 8ft and height of 3ft. What’s the volume?
stepladder [879]

Step-by-step explanation:

1/3 πr²h

Given

diameter (d) = 8ft

radius (r) = d/2 = 8/2 = 4 ft

height (h) = 3 ft

Volume of cone

\frac{1}{3} \times \pi {r}^{2}  h

\frac{1}{3}  \times 3.14 \times  {4}^{2}  \times 3

\frac{150.72}{3}

=50.24 ft³

How many seconds are in 10 hours
enot [183]
There are 60 seconds in a minute.

There are 60 minutes in an hour.

This means that there'd be 600 minutes in 10 hours.

And if there are 60 seconds in a minute, there are 600 x 60 seconds in 600 minutes.

600 x 60 = 600 x 10 x 6 = 6000 x 6 = 36000

So we know that there are 36000 seconds in 10 hours.
