Answer:
y = -7
Step-by-step explanation:
If x equals -14 then you would plug it in and the equation would be -2(-14)-3y=49
The new equation would be 28-3y=49
Then you would subtract 28 from both sides and get -3y=21
Lastly you would divide both sides by -3 and get y=-7
Answer:The difference between the medians is 2.5
Step-by-step explanation: So how I did this is first I found the median of the two plots (median=the middle number in a group of values) so anyway I lined it all out because I find it easier to do it that way (20,25,25,30,30,30,30) so the answers I got for both plots were -plot A=32.5 and plot B=30 than difference means subtract so 32.5-30=2.5
Answer:
Christian has more candy bar left because 1/8 is less than 1/3.
Step-by-step explanation:
Surface area of the cylinder = 2 pi r * 40 = 2 pi * 3* 40 = 24 pi
of the cone this is pi * 3 * 5 = 15pi
of the hemisphere this is 1/2 * 4 * pi * 3^2 = 18pi
So the answer is 24pi + 15pi + 18pi = 57pi = 178.98 cm^2
