Answer:
y=1.2x-3
Step-by-step explanation:
I had this as an rsm problem a few weeks ago and forgot how to solve it lol hope this helps
so obviously first of all find three sherical objects or balls of varioius sizes to make it easier get a large medium and small sized.
then on scratch paper sketch those objects (im assuming by the looks of it you would trace them if not just draw them then take measuring tape or a ruler across to measure said object) now you arent told what units to measure in but id assume to stick with one unit either inches or cm
mesure the length across which is the circumference
now you would just have to do your calculations by finding the radius and volume and surface area
remember volume is (*units) cubed and suface area is (*units) sqared
Hello from MrBillDoesMath!
Answer:
35x - 600
Discussion:
Area of unshaed rectangle =
area of full rectangle - area of shaded rectangle =
35x - 600
Thank you,
MrB
The right answer is Option A.
Step-by-step explanation:
Let,
x be the postcards
y be the large envelops
According to given statement;
14x+5y=12 Eqn 1
10x+15y=24.80 Eqn 2
Multiplying Eqn 1 by 3;
Subtracting Eqn 2 from Eqn 3;
Dividing both sides by 32
Putting x=0.35 in Eqn 1;
Dividing both sides by 5
Therefore, one large envelope costs $1.42
The right answer is Option A.
