Answer:
C.
Step-by-step explanation:
Multiply both sides by 15, which gives you r≥-75
Since the graph has to go in the direction of numbers greater than -75, that would be -74, -73, -72, etc. So, it is C.
The slope is m=3/4. Hope this helped you with your work let me know if I got the answer correct.
Draw a triangle with shortest side on the ground (horiz.). The length of this side is 80 feet. Two angles touch the ground: a right angle, and the 70 degree angle.
Then the height of the building is the 2nd shortest side.
The tangent function is the appropriate one to use here:
opp h
tan 70 deg = -------- = ----------
adj 80 ft
h
Since tan 70 deg = 2.75, 2.75 = -------
80 ft
so h = building height = (80 ft)(2.75) = 219.8 ft
9w+45= amount of money she’ll have after any amount of weeks.
So, since W is weeks... and you have 9 weeks, you do (9x9)+45.
Then you get 81+45, which is 126. She will have $126 after 9 weeks
$0.29 * 3 = $0.87
$0.98 * 2 = $1.96
$1.39 * 1 = $1.39
0.87 + 1.96 = 2.83
2.83 + 1.39 = 4.22
10.00 - 4.22 = $5.78
she will get $5.78 back!
