Answer:
Step-by-step explanation:
A. Rate of change (or slope) is $50
The initial tutoring fee starts out at $1200 in 2005
How do you know? Each year the cost goes up $50
2005 = $1200
2006 = $1250
2007 = $1300
2008 = $1350
B. y=50x+b
Answer:
The ratio of blue to red marbles is 3 to 8.
Hope this helps :) have a good day!
Here, numbers are: 1.4 and 1 4/5 = 9//5 = 1.8
Now, you need to know, which number is between 1.4 and 1.8
1.34 is lower than 1.4 So, it can't
170% = 170/100 = 1.7
So, 170% is that number between 1.4 and 1 4/5
Hope this helps!
Answer:

Step-by-step explanation:
As we are given the adjacent (a) side and the hypotenuse (h), we can use the cosine function to find the measure of angle B.
Recall that 
This means that in order to find B, we need to take the inverse of cosine
This gives us

From a calculator, we find that the answer of this is

When this is rounded to the nearest hundredth, we get

The answer would be 9, because you have the 3 edges along the rectangles, and then 3 edges each for the triangles. So 3 + 3 + 3 = 9. I hope this helps!
