If 15% of an item is $18.00 what was the original price?
larisa [96]
<span>from the whole price,
15% of this price is equal to $18.00.
therefore if 15 % equals $18.00
                                                                     
then 100% is the original price therefore 100 % = 18.00 / 15 % x 100% = $120 therefore original price = $120</span>

Steve, 18 years old, is three times as old as his brother Daniel. How old will Steve be when he will be twice as old as Daniel?
gtnhenbr [62]
18 ÷ 3 is 6, which means that Daniel is 6, and there is a 12 year gap between Steve and Daniel.

12 x 2 is 24, so therefore when Steve is 24, Daniel will be 12, so Steve is twice as old as Daniel:)

Find the percent of increase or decrease? 2.5y to 1.5y
horsena [70]

Answer:

From 2.5 y to 1.5 y there is a 40 % DECREASE in the value.

Step-by-step explanation:

Here, the initial value = 2.5 y

The final value of 1.5 y

Now,as Final Value  < Initial Value

So, there is a DECREASE IN THE VALUE.

Now, decrease in the value  = Initial value  - Final Value  

                                                =  2.5 y = 1.5 y  = 1 y

or, there is a decrease of ( 1 y) in the given value.

Now, Percentage decrease in the value is given as:

\textrm{Percentage Decrease} = \frac{\textrm{The decrease in the value}}{\textrm{The initial Value}} \times 100\\ = \frac{1 y}{2.5 y}  \times 100 = 40

or, Percentage Decrease = 40%

Hence, from 2.5y to 1.5y there is a 40 % DECREASE in the value.

A circular city park has a sidewalk directly through the middle that is 111 - feet long. If each bag of fertilizer covers 50 squ
scZoUnD [109]

Answer:

Step-by-step explanation:

The circular city park has a sidewalk directly through the middle that is 111 - feet long. This means that the diameter of the park is 111 feet.

The formula for determining the the area of a circle is expressed as

Area = πr²

Where

r represents the radius of the circular floor.

π is a constant whose value is 3.14

From the information given,

Diameter = 111 feet

Radius = diameter/2 = 111/2 = 55.5 feet.

Area of park = 3.14 × 55.5² = 9671.985 feet²

If each bag of fertilizer covers 50 square feet, then the number of bags needed is

9671.985/50 = 193.44 bags
