The price of lettuce was $1.25 one week and $1.50 the next week.  Find the percent of increase.
melomori [17]
So the lettuce went up by 0.25 or 25c, now, if we take 1.25 to be the 100%, how much is 0.25 in percentage off of it?

\bf \begin{array}{ccllll}
amount&\%\\
\text{\textemdash\textemdash\textemdash}&\text{\textemdash\textemdash\textemdash}\\
1.25&100\\
0.25&x
\end{array}\implies \cfrac{1.25}{0.25}=\cfrac{100}{x}\implies x=\cfrac{0.25\cdot 100}{1.25}

Step-by-step explanation:

you don't know how exponents work ?

the exponent simply says how often the base value has to be multiplied by itself.

e.g. 5³ = 5×5×5 = 125

and when it says x=2, then you need to put 2 at every location, where is says "x".

so,

x⁵ for x = 2 means 2⁵ = 32

8² = 64

2⁴ = 16

A cone has a height of 11 meters and a radius of 7 meters . What is the volume?
baherus [9]

Answer:

V = 564.2 m^3

Step-by-step explanation:

The volume of a cone is given by

V = 1/3 pi r^2 h  where r is the radius and h is the height

V = 1/3 pi (7)^2 (11)

V =539 /3 * pi

Letting pi be approximated by 3.14

V = 564.1533333 m^3

Rounding to the nearest tenth

V = 564.2 m^3
