Step-by-step explanation:

recall in a linear equation expressed in the form

y = mx + b,

m represents the slope or the rate of change in the value of y for a unit change in the value of x

b represents the y-intercept (i.e the value of y when x = 0)

If you compare these definitions to what was given in the question, the rate of change in snowfall is given as 1/2 inches per hour. This is equivalent to the m value in our general equation above. Hence we can say that the rate of change in snowfall is equal to the slope of the graph.

The question also states that before the snow even started to fall (i.e when x=0 hours), there was already 8 inches on the ground. This is equivalent to the value of b in our general equation above. Hence we can say that the y-intercept is representative of the 8 inches that was already on the ground when the snow started falling.

Find m∠1 if m∠2=73°, m∠3=107°, m∠4=92°.

Nata [24]

If you are describing a quadrilateral, then the answer is
m1 + 73 + 107 + 92 = 360
m1 + 272 = 360
m1 = 360 - 272
m1 = 88 degrees.
If it is anything but a quadrilateral, it would be a good idea to state what it is.

What is the length of the hypotenuse of the triangle ?

Shkiper50 [21]

Answer:

The length of the hypotenuse of the triangle is about 14.14 units.

Step-by-step explanation:

You can determine this by using the Pythagorean Theorem.

a^2 + b^2 = c^2

To find the hypotenuse, take sides a and b (10 and 10) and square them. You get 100. When you add 100 and 100 together, you get 200, which equals c^2. Find the square root of 200 to find the hypotenuse.

Trey had 440 songs on his mp3 player.now he has 473 songs.what is the percent of increase in the number of songs on his mp3 play

olga55 [171]

Answer:

There is 7.5% increase in the number of songs on his mp3 player.

Step-by-step explanation:

Original Songs in mp3= 440 songs

Final Songs in mp3= 473 songs

We need to find percent of increase in the number of songs on his mp3 player.

The formula used is: $Percent \ of \ increase = \frac{Final \ Value \ -\ Original \ Value}{Original \ Value} \times 100$

Now putting values and finding percent of increase

$Percent \ of \ increase = \frac{Final \ Value \ -\ Original \ Value}{Original \ Value} \times 100\\Percent \ of \ increase = \frac{473-440}{440} \times 100\\Percent \ of \ increase = 7.5\%$

So, there is 7.5% increase in the number of songs on his mp3 player.

Kim was walking down a rocky path for 4 minutes the election dropped steadily altogether it dropped 8 feet what was the chance i

natali 33 [55]

in 4 minutes it changed 8 feet

so 8/4 =2 feet per minute change

and since it dropped it would be a negative change so -2 feet per minute
