to find the height

multiply the length of shadow by the tangent of the angle

18 * tan(28) =9.5708

the tree is around 9.6 feet tall

Answer: 1) gets steeper

2) gets less steep

3) Negative.

Step-by-step explanation:

Since, the slope intercept form of a line is,

y = mx + c

Where m represents the slope of the line,

If m = positive , then the line has positive slope,

While If m = negative then the line has negative slope.

Now, The line having the maximum absolute value of m is called stepper line,

Here, the equation of line is,

y = mx

⇒ m is the slope of the line,

1) Since, |1| < |3|

⇒ When m changes from 1 to 3 then the line gets steeper.

2) Since, |-6| > |-1|

⇒ When m changes from -6 to -1 then the line gets less steep.

3) If m = Negative

Then the slope of the line is negative.

A coffee bean processor can dry 4,815 pounds of coffee beans in 3 hours which unit rate correctly reflects the speed of the proc

zimovet [89]

Answer:

605 pounds/hour

Step-by-step explanation:

Given that a coffee bean processor can dry 4815 pounds of coffee in 3 hours.

We have to find the speed of the processor

By speed of the processor here we mean the unit rate i.e. no of pounds of coffee beans that the processor can process in one hour.

This is a question of direct variation

Since we have for 3 hours 4815

for 1 hour = $\frac{4815}{3} =605$ pounds/hour

So answer is 605 pounds/hour

Verify:

If unit rate is 605 pounds/hour, for 3 hours =605(3) = 4815 pounds

Thus verified

Ernie earned $121.50 more than Kaylin. Tria earned $35 less than 3 times the amount Kaylin earned. Ernie, Tria, and Kaylin earne

Dvinal [7]

X - Ernie, y - Kaylin, z - Tria
x = y + 121.50
z = 3y - 35
x + y + z = 579
-------------------------
z = 3 y - 35 => - 3 y + z = -35
y + 121.50 + y + z = 579
---------------------------------
- 3 y + z = - 35 / · ( -1 )
2 y + z = 457.50 (we will use the elimination method)
---------------------------------
3 y - z = 35
2 y + z = 457.50
----------------------
5 y = 492.5, y = 492.5 : 5 = 98.5
z = 3 · 98.5 - 35
z = 260.5
Tria earned $260.5
