Answer:
X Company charges more than Company Y
Step-by-step explanation:
Given:
Cost of X company =
Cost of Y Company =
for n minutes
Cost of X company for n minutes =
Cost of Y Company for n minutes =
Difference for n minutes we get by Subtracting Cost of Y Company for n minutes by Cost of X company for n minutes
Difference for n minutes = =
X Company charges more than Company Y
The answer is Y = -2X + 7
Your in luck! I was just learning these percent things today 'xD but Not in luck at the same time. I will answer the 2 questions that's the most I can do.
1. $17.50 with a 7% sales tax
Answer: 17.50 times .07 equals 1.23
17.50 plus 1.23 equals 18.73
The answer is $18.73
2. 21.95 with a 4.25% sales tax
Answer: 21.95+4.25=26.20
Hope this helps!! :D this took me a while to figure out and used a bit of my time. So I hope the time was worth it! :)
Answer:
The slope of this curve where it meets the right pole is 1.130
The angle between the line and the right pole is 41.51
°
Step-by-step explanation:
Given that ;
x = 9 m;( i.e half of the distance of the two poles at 18 meters apart.
= 1.130
The slope of this curve where it meets the right pole is 1.130
The angle between the line an the right rope can be determined by using the tangent of the slope .
tan ∝ = 1.130
∝ = tan⁻¹ (1.130)
∝ = 48.49°
The angle is θ; so
θ = 90 - ∝
θ = 90 - 48.49°
θ = 41.51
°
Thus; the angle between the line and the right pole is 41.51
°
