Answer:
Cartesian Coordinate System
• Also called
rectangular coordinate
system
• x- and y- axes intersect
at the origin
• Points are labeled (x,y)
Polar Coordinate System
– Origin and reference
line are noted
– Point is distance r from
the origin in the
direction of angle θ,
ccw from reference
line
– Points are labeled (r,θ)
Cartesian to Polar Coordinates
• r is the hypotenuse and θ
an angle
θ must be ccw from
positive x axis for these
equations to be vali

Answer: 60.5
Step-by-step explanation:
Since you’re solving for y, you want to get it by itself to get a clean reading answer of y= blank.
So in 6y=363 you would want get rid of that 6 from the y, do you would divide both sides by 6.
6y/6 = 363/6
And then you’d get
y=60.5 once you finish dividing.
Answer:
19 points
Step-by-step explanation:
convert points to percents:
20 points = 100%
19 points = 95%
18 points = 90%
17 points = 85%
percent-wise, her average prior to another quiz is 92.5
so if she wants to keep to maintain that average she must get 18 1/2 points; if teacher doesn't award partial credit then she needs to get a full 19 points
Marty's grandmother cans spaghetti sauce. Last year she canned some specifically for Marty. She ended up with 25 quarts full. Marty noticed, however, that a quart of sauce is too much for her meals (she only cooks for herself). If she wants her grandmother to can the sauce in pints this year, how many pint jars should she buy to put it in?
