I don't know what this question is asking exactly, but if i am right, it is asking for the ratio of heads flipped to tails flipped. If this is correct, then the ratio would be 24 to 8. My reasoning for this is, it already tells you that you have 8 times that tails was flipped, and all you have to do to figure out the amount of times heads if flipped it to subtract: 32-8=24, so that means that heads was flipped a total of 24 times. The last thing that you have to do is to put it into a ratio, and in the order it gives you initially, which would make the answer (3 ways):

1)   24 to 8
2)   24 : 8
3)   24/8

I hope this helps you.

malfutka [58]
We know that

if the bird flies 5/6 miles north for -------------> 3/8 miles east
then
for 1 mile north------------------------------> X miles east?
X=(3/8)/(5/6)-------> 18/40-------> 9/20 miles

the answer is
9/20 miles

Area of triangle = 24
Marina86 [1]

Answer:

x=-2\pm2\sqrt13

Step-by-step explanation:

The area of the triangle is;

A=\frac{1}{2} \times b\times h

b=x+4

h=x

Area=A=24

A=\frac{1}{2}\times[(x+4)\times x] \\24=\frac{x^{2} +4x}{2} \\24\times2=x^{2} +4x\\48=x^{2} +4x\\x^{2} +4x-48=0\\

This can only be solved by the quadratic formula.

x=\frac{-b\pm\sqrt {b^{2}-4ac }}{2a}

where;

a=1\\b=4\\c=-48

and we get,

x=-2\pm2\sqrt13

A total of
LuckyWell [14K]
If we make a an integer that represents the adults that bought tickets, and s the number of students, then we have the equations a+s=682, and a=68+s. 

Using the second equation, we find that s=a-68, so we plug this value of s into the first equation to get a+(a-68)=682. We simplify to find 2a=750. We divide by 2 to isolate the desired variable to get a=\boxed{375\text{ adult tickets were sold}}.
