Alright, lets get started.
Jim was thinking of a number.
Suppose the number Jim was thinking, is x.
Jim adds 20 to it means number will be = 
And Jim doubles it, means 
Jim gets 99.2 and as per us, he gets 
So, making them equal


Subtracting 40 in both sides



It means the original number is 29.6. : Answer
Hope it will help :)
5 for $3.50 has the lowest unit price because 3 for $2.19 is $0.73 per item, 4 for $3.00 has a in it price at $0.75, 5 for $3.50 has a unit rate for $0.70 per item, and $0.72 per item is more expensive than $0.70 per item
Answer:
10.5%
Step-by-step explanation:
The tangent of the angle is the ratio of rise to run.
tan(angle) = grade
tan(6°) ≈ 0.105 = 10.5%
The grade will be 10.5% for an angle of elevation of 6°.
Answer:
a) Job A.
Step-by-step explanation:
Time, t = 2000 hours per year
Job A:
Salary = $13 per hour
Job B:
Salary = $11 per hour
Healfh insurance = $3400 per year
= $3400/2000
= $ 1.7 per hour
B:. Mb = $11 × 2000 = $22000
Health insurance costs 3400$ per year so while we are working our job A we have: so $11.3 × 2000 = $22600. So on job A we earn $600 per year more than on job B.
The midpoint of a line segment is the point that is located exactly in the middle of two points. It is the average of both points, which is the average of the two coordinates x, and of the two coordinates y.
We have then:
M = (((x1 + x2) / 2), ((y1 + y2) / 2))
Substituting values:
M = (((0 + 0) / 2), ((0 + 15) / 2))
M = (0, 7.5)
Answer:
The y-coordinate of the midpoint of a vertical line segment with endpoints at (0, 0) and (0, 15) is:
y = 7.5
