Answer:

3 cones

Step-by-step explanation:

It is given that there is a cylindrical shaped can and also a coned shaped paper cup. The radius and height of both the cylindrical can and the cone shaped paper cup are same.

So when we fill the cylindrical can with the full coned paper cup, it will take three cones of the paper cup to fill the can with water. This because the volume of a cone is $\text{one-third}$ of the volume of a cylinder that have the same base radius and height.

The rectangular top of a small box has dimensions of one 40 mm x 230 mm. How long in centimeters with a ribbon need to go all th
kozerog [31]

Answer:

540 mm

Step-by-step explanation:

Here we are given a rectangular box with dimensions of the top surface as 40 mm and 230 mm

We are asked to determine the measurement of the ribbon which may go all the way around the edge of it. Basically we are being asked the perimeter of the top surface. The perimeter is given as the

P=2 (l+w)

l = 230

w = 40

P=2(230+40)

P=2 x 270

P= 540

Hence we need 540 mm of ribbon  to go all the way around the edge of the top of the box.

The difference between the simple and compound interest for a certain sum of money of 3 years at 5% per annum is Rs.61.0. Find t
miss Akunina [59]

5% interest compounded annually for 3 years multiplies the initial balance by

... 1.05^3 = 1.157625

5% simple interest for 3 years multiplies the initial balance by 1 + 3*0.05 = 1.15.

The difference of these multipliers is

... 1.157625 - 1.15 = 0.007625

If the difference in account balance is Rs 61.00, then the invested principal amount P is

... P*0.007625 = 61.00

,.. P = 61.00/0.007625 = 8000.00

The sum of money is Rs 8000.

The exam had 60 questions.Phelix got 85% correct. How many questions did he answer correctly?
hichkok12 [17]
Y is 85% of 60

Equation: Y = P% * X

Solving our equation for Y
Y = P% * X
Y = 85% * 60

Converting percent to decimal:
p = 85%/100 = 0.85

Y = 0.85 * 60 
Y = 51
