Answer:
Step-by-step explanation:
1=no
the rest are pretty easy, all you do is plug in your (x.y)-->x+y=?
Answer:
A) A 9% downhill grade means that the decrease in elevation of the road over the segment is 9% of the change in Horizontal distance over the same segment. In other words, for every 100 horizontal feet the road descends 9 feet and the road has a slope of 0.09 vertical feet per horizontal foot.
Step-by-step explanation:
A Certain westbound U.S highway truck route near a river has a downhill grade of 9%
A) A 9% downhill grade means that the decrease in elevation of the road over the segment is 9% of the change in Horizontal distance over the same segment. In other words, for every 100 horizontal feet the road descends 9 feet and the road has a slope of 0.09 vertical feet per horizontal foot.
In other to make things clear, lets assume
for X = 1 , y = 9% = 0.09
for y = 9 , x = 9 / 0.09 = 100
slope = y/x = 0.09 / 1 = 0.09
Answer:
The number is 60
Step-by-step explanation:
Of is multiply and is means equals
20% * N = 12
Changing to decimal form
.20 N = 12
Divide by .20
.20N/.20 = 12/.20
N = 60
The number is 60
Answer:
It should be d=2.25t
Step-by-step explanation:
The question only contains 2.25 not 2 or 4 and also you would multiply it
18 times x = $75
I wasn’t able to find the multiplication sign on my keyboard and didn’t want to confuse you so I replaced x with times
