If you want to easily find the solution you can use your calculator.
Just divide 77 by 110 and see the result.
77/110 = 0.7 = 7/10 = 70/100 = 70%
100% - 70% = 30%
Explanation
110*x=77
x=77/110, but the answer is not a percent
So 77/110 = ?/100 => ?=77*100/110=70 => 70%
But since 70% does not represent a percentage decreasement, we need to subtract it from the 100%
100% - 70% = 30%
Answer:
Part 16)
Part 17)
Step-by-step explanation:
Part 16) we know that
The solution of the inequality is the shaded area below the solid line
The slope of the solid line is negative
The y-intercept of the solid line is the point (0,2)
The x-intercept of the solid line is the point (2,0)
The slope of the solid line is
The linear equation of the solid line in slope intercept form is
therefore
The inequality that represent the graph is
Part 17) we know that
The solution of the inequality is the shaded area above the dashed line
The slope of the dashed line is positive
The y-intercept of the dashed line is the point (0,-1)
The x-intercept of the dashed line is the point (3,0)
The slope of the dashed line is
The linear equation of the dashed line in slope intercept form is
therefore
The inequality that represent the graph is
1) Converting true bearing to quadrant:
a) 140 degrees.
Taking North as origin, it would be:
E50S
So, final answer for this part is E50S
b) 94 degrees
Taking North as origin position, it would be: E04S
So, final answer for this part is E04S
2) Converting to true-bearing:
a) S50W = from north, it would be: 180+ 50 = 230 degrees
So, 230 degrees is the answer.
b) N15W = from north, in anti-clock wise direction (direction in which we usually calculate) would be: 360-15 = 345
So, 345 degrees is the answer.
Hope this helps!
Answer:
11
Step-by-step explanation:
when a = -2
5 - 3a
= 5 - 3(-2)
= 11
Answer:
I don't know if this will be right but:
$20 - $2.50x
Step-by-step explanation:
You start of with 20 dollars, for each day (x), $2.50 will be taken out of your 20 each day.
