Answer:
x=36 degrees
Step-by-step explanation:
Remember that all angles of a triangle must add up to 180 degrees due to the Angle Addition Postulate. So let's plug it in! x+65+79=180
Now you solve, x=180-79-65
x=36!
x=36 degrees
Answer:
D) 3:10
Step-by-step explanation:
Well only blues and yellows are at least $5. there are 25 yellows and 5 blues and if you add them together there's 30 in total. Now compare that 30 to 100 and you have 30:100. In the simplest form you have to divide both sides by 10 and it becomes 3:10.
Answer:
Approx. 12.124 units tall
Step-by-step explanation:
Since you need to find the height (which is adjacent to the given angle), you need to use cosine (adj. over hypotenuse).
cos(30) = x/14
Multiply both sides by 14:
14cos(30) = x

A) The rate of change is -40 songs each week, that is because the amount of songs left to be downloaded decrease by 40 each week
B) lets use 2 points of the graph p1(0, 200), p2(1, 160)
calculate the slope:
m = (y2- y1)/(x2 - x1) = (160 - 200)/(1 - 0)
m = -40
now use line equation in form point-slope:
y - y1 = m(x - x1)
y - 200 = -40(x - 0)
y = -40x + 200
We need the picture. So do you. That's why it's printed right there.
