A recycling plant processes an average of ( 2/3) ton of glass each minute. At approximately what rate does the recycling plant p

Olegator [25]

First, you need to find the amount of rate of change/slope of this equation of minutes, which is 2/3 of a ton.

We will then multiply 2/3 by 60, because we need to find how much in an hour. (60 minutes = 1 hour)

2/3 x 60 = 40

We will then multiply 40 by 24, because we need to find approximately what rate the recycling plant processes glass in a full day. (24 hours = 1 day)

40 x 24 = 960

We now have our answer:

The recycling plant processes 960 tons of glass in a whole day.

Hope this helps! :)

8.5 is the nearest one

square root of 72 is about 8.48

rounding to the nearest tenth gives you 8.5

At 2:00pm a car's speedometer reads 20mph, and at 2:10pm it reads 30mph.

Dmitry [639]

Over this 10-minute interval, the car's average acceleration is

$\dfrac{30\,\mathrm{mph}-20\,\mathrm{mph}}{10\,\mathrm{min}}=\dfrac{10\,\mathrm{mph}}{\frac16\,\mathrm h}=60\dfrac{\rm mi}{\mathrm h^2}$

The MVT says that at some point during this 10-minute interval, the car must have had an acceleration of 60 mi/h^2.

Find the coordinates of the third vertex that completes the construction of a right triangle on the coordinate plane.

Neko [114]

Answer:

(7,a) Where a ∈ R - {7}

OR

(-2,a) where a ∈ R - {-2}

Step-by-step explanation:

The coordinates of the given line from the right to the left are:

(7,1) and (-2,1)

So, to make a right triangle, we need to make a right angle or by another words, we need to a make a perpendicular line to the given line (i.e: a vertical line parallel to the y-axis at one of the given points)

So, the third vertex must be on the line x=7 or x=-2

So, the coordinates of the third vertex is:

(7,a) Where a ∈ R - {7}

OR

(-2,a) where a ∈ R - {-2}
