Answer:
sin C=20/25=4/5
cos C=15/25=3/5
tan C=20/15=4/3
Step-by-step explanation:
sine is opposite/hypotenuse
cosine is adjacent/hypotenuse
tangent is opposite/adjacent
Answer:
B, $51.53
Step-by-step explanation:
since $1.55 had been subtracted by the original price which is now $49.98
Add back the $1.55 to $49.98 to get $51.53
First, pass all the rate of inflation to ballons/hour
John: 1 b/15s * 3600 s/h = 240 b/h
Jamie: 1 b/20s * 3600 s/h = 180 b/h
Jake: 180 b/h
Then sum the rates to obtain the total rate
Total ballons per hour: 240 b/h + 180 b/h + 180b/h = 600 b/h
If it passes x hours the number of ballons inflated is 600*x
The number of ballon defective are 600*x/80
The number of ballons effectiveley inflated = 600x -600x/80 = 600x - 7.5x = 592.5x.
Answer: option A)
Answer:
y = -1/2x - 4
Step-by-step explanation:
The slope intercept form of a line is y = mx + b. The slope is -1/2 so substitute m = -1/2. The y-intercept is b so substitute b = -4.
y = -1/2x - 4
