Answer:
$230n-$2100
Step-by-step explanation:
Profit=revenue-cost
Cost=$2100+$130×n
Revenue=$360×n
Profit=$360n-($2100+$130n
=$360n-$2100-$130n
=$230n-$2100
Answer:
15
Step-by-step explanation:
900 light bulbs per hour
60 minutes per hour
X lightbulbs per minute
Divide 900 lightbulbs by 60 minutes
15
The rate is 15 light bulbs per minute
Answer:
x = 62 degrees
Step-by-step explanation:
Since this is a right angle, we can use trig functions
cos theta = adjacent/ hypotenuse
cos x = 3.7/7.9
Taking the inverse cos of each side
cos ^ -1 ( cos x) = cos ^-1 (3.7/7.9)
x =62.07246803
To the nearest degree
x = 62 degrees
Answer:
Average ROC = 0
Step-by-step explanation:
Average ROC : (f(b) - f(a)) / (b - a) ... slope = (y'-y) / (x'-x)
a = -3 f(a) = 10 ... x=-3, y=10
b = 6 f(b) = 10 ... x'=6, y'=10
Average ROC = (10 - 10) / (6 - -3) = 0 / 9 = 0
Answer:
X=-1
Step-by-step explanation:
0=2x+2
subtract 2 out
-2 = 2x
divide 2 on both sides x = -1
