Mathematics
1 answer:
tankabanditka [31]3 years ago
7 0

Answer:

40%

Step-by-step explanation:

Total students = 25

Boys = 15

Girls = 25 - 15 = 10

Percent of girls = 10/25

Percent is out of 100.

=> 10/25 = x/100

=> Cross multiply

=> 25 * x = 100 * 10

=> 25x = 1000

=> 25x/25 = 1000/25

=> x = 40

So, 40% are girls

An ice cream cone has a diameter of 3 inches.The distance from the top of the cone to the point at the bottom (height) is 5 inch
solong [7]

Answer:

11.781 cubic inches (round accordingly)

Step-by-step explanation:

The formula for the volume of a cone is:

V=\frac{1}{3}\pi  r^{2} h

where r is the radius and h is the height.

For our ice cream cone:

d = 3 inches

r = 1.5 inches (the radius is half of the diameter)

h= 5 inches

So all we have to do is plug in our values and solve for the volume:

\frac{1}{3}\pi  (1.5)^{2}(5) = 11.781

So our final answer is around 11.8 cubic inches.

\bf y = x(2x+5)(2x-7)\impliedby \textit{setting y = 0}
\\\\\\
0=x(2x+5)(2x-7)\implies 
\begin{cases}
0=x\\
----------\\
0=2x+5\\
-5=2x\\
\cfrac{-5}{2}=x\\
----------\\
0=2x-7\\
7=2x\\
