Choose yes or no to tell whether the expression represents a 20% discount off the price of an item that originally costs d dollars.



Option A and C is correct.

Step-by-step explanation:

Discount is defined as a reduced price on something being sold or at a price lower than that item is normally sold for.

For a 20% discount,


Initial prices = $ d

Discounted price = % discount × original/initial cost

= 20/100 × d

= 0.2 × d

Selling price = original cost - discounted price

= d - 0.2d

= 0.8 × d

= 0.8d


A: Yes


C: Yes

D: No

What is the volume of a cone with a radius of 18 cm and a height of 10 cm? Use 3.14 for pi. Round your answer to the nearest tenth. (4 points) 3275.4 cm3 3540.8 cm3 4000.2 cm3 3391.2 cm3 Previous Next


Answer: 3391.2\text{ cm}^3

Step-by-step explanation:

The volume of cone is given by :-

V=(1)/(3)\pi r^2 h, where r is radius and h is height of the cone.

Given: Radius = 18 cm

Height : 10 cm

Then , the volume of the cone will be :-

V=(1)/(3)(3.14) (18)^2 (10)=3391.2\text{ cm}^3

Hence, the volume of the cone = 3391.2\text{ cm}^3

I hope this helps you

Volume of Cone = 1/3.pi.r^2.h




Chelsea by 8 packs of markers. Each pack contains the same number of markers. Chelsea gives 10 markers to her brother. Then she has 54 markers left. How many markers were in each pack?

Step-by-step explanation:

You would add 10 to 54 and then divide by 8.

The difference between the water levels for high and low tide was 3.6 feet. The low is .2 foot. Write an equation to find the water level at high tide.



H_(x) = 3.8ft

Step-by-step explanation:

Thinking process:

Let the problem be expressed like this:

The water level in the high tide be given by: H_(x)

The water level in the high tide be given by: L_(x)

The difference between the two is given by the equation: H_(x) -L_(x)  = 3.6

The height in in low tide is 0.2 ft, so the equation becomes:

H_(x) - 0.2 = 3.6 \nH_(x)  = 3.8ft

.2+3.6=3.8 because all you do is add the .2 feet with 3.6 feet

The students council is asking people to donate money for the new park outside the school. Everyone who makes the suggested donations amount will be given a bracelet. If everyone donates the suggested amount, b bracelets are given away, what algebraic expression represents the total amount collected in donations


Let each amount be  y.

Since b bracelets were given away, it number of persons who made the amount = b.

Total = b*y

Total amount = by.
