Answer:

The price of candy bar is 75 cents

Step-by-step explanation:

Let c be the price of candy bar and d be the price of drinks

Then according to given statements

60c+110d = 265\ \ \ \ Eqn\ 1\\120c+90d = 270\ \ \ \ Eqn\ 2

Multiplying equation 1 by 2

120c+220d = 530\ \ \ \ Eqn\ 3

Subtracting equation 2 from equation 3

120c+220d - (120c+90d) = 530 - 270\\120c+220d-120-90d = 260\\130d=260

Dividing both sides by 130

\frac{130d}{130} = \frac{260}{130}\\d = 2

Putting d=2 in equation 1

60c+110(2) = 265\\60c + 220 = 265\\60c+220-220 = 265-220\\60c=45\\c = \frac{45}{60}\\c = 0.75

Price of candy bar is $0.75 or 75 cents

Hence,

The price of candy bar is 75 cents

A cylinder and a cone have the same volume. The cylinder has radius x and height y. The cone has radius 2x. Find the height of t
weqwewe [10]
V(cylinder)=πR²H
Radius of the cylinder R=x, height of the cylinder H=y.
We can write for the cylinder
V(cylinder)=πx²y

V(cone) =(1/3)πr²h
Radius of the cone r=2x.
We can write for the cone
V(cone)= (1/3)π(2x)²h=(1/3)π *4*x²h

V(cylinder) =V(cone)
πx²y=(1/3)π *4*x²h
y=(4/3)*h
h=(3/4)*y
