At time tequals0, water begins to drip out of a pipe into an empty bucket. After 14 minutes, there are 7 inches of water in th

Vaselesa [24]

Answer:

$w=0.5t$

Step-by-step explanation:

Given:

'w' represents inches of water left after 't' minutes of time.

The dripping out of water is a linear function.

At time 't' equal to 0, the bucket was empty.

After 14 minutes, there are 7 inches of water in the bucket.

A linear function model is of the form: $w=mt+b$

$Where, m\to\textrm{dripping rate of water}\\b\to\textrm{water level at t=0}$

Now, at $t=0,w=0(\textrm{As bucket was empty})$

At $t=14,w=7$

Therefore, plugging these values in the above linear model and solving the system of linear equations. This gives,

$0=m(0)+b\\0=0+b\\b=0\\\\7=14m+0\\m=\frac{7}{14}=0.5\ in/min$

Therefore, the values of 'm' and 'b' are 0.5 and 0 respectively.

Thus, the linear model is given as:

$w=0.5t$

Find the value of x I’d appreciate if you could explain as well if not that’s fine

Kipish [7]

All the angles in a circle equal to 360 degrees. So basically just add up all the known values: 23+23+15=61 and then subtract that from 360: 360-61=299.

You can also do 23+23+15+x=360. Adding it all becomes 61+x=360, subtract 61 from both sides of the equation, and you get x=299.

(Something to help remember is that the angle is obtuse, meaning it’s automatically more than 90 degrees, hope this helps!)
