a local high schools cheerleading squad is selling snow cones during lunch to raise money for a national cheerleading competitio

svlad2 [7]

We have:

Volume of cone = 535 cm³ at the maximum
Height of cone= 8cm

We know the formula to find volume of cone is $\frac{1}{3} r^{2} \pi h$

We need to find the radius of the base of the cone
$535= \frac{\pi r^{2}8} {3}$
$535*8= \pi r^{2}$
$\frac{4280}{\pi}= r^{2}$
$r= \sqrt{ \frac{4280}{ \pi} }$
$r=36.9$ to the nearest one decimal place

The width of the opening of the cone is the diameter of the circle. Diameter is twice the radius, hence 2×36.9=73.8 cm

First find the numbers that are divisible by 3.
3, 6, 9, 12, 15, 18, 21, 24
There are 8 numbers divisible by 3 so there are 16 that are not divisible by 3.
P(not div by 3) = 16/24 = 2/3

The hypotenuse of a right triangle is twice the length of one of its legs. Th length of the other leg is three feet. Find the le

IgorLugansk [536]

Let
x----> the length side of the hypotenuse
y----> the length side of the unknown leg

we know that
x=2*y----> equation 1
applying the Pythagoras Theorem
x²=y²+3²-----> equation 2

substitute equation 1 in equation 2
[2*y]²=y²+3²----> 4*y²-y²=9-----> 3*y²=9----> y²=3
y=√3 ft
x=2*y----> x=2*√3 ft

the answer is
the lengths of the three sides are
hypotenuse=2√3 ft
one leg=√3 ft
other leg=3 ft
