A snail travels 10 cm in 4 minutes. At this rate: How long will it take the snail to travel 24 cm?
atroni [7]

It will take the snail 9.6 minutes to travel 24cm.

Step-by-step explanation:

Distance covered in 4 minutes = 10 cm

Ratio of distance to time = 10:4

New distance = 24cm

Let,

x be the time period

Ratio of new distance to time = 24:x

Using proportions;

Ratio of distance to time :: Ratio of new distance to time

10:4::24:x

Product of mean = Product of extreme

24*4=10*x\\96=10x\\10x=96

Dividing both sides by 10

\frac{10x}{10}=\frac{96}{10}\\x=9.6\ minutes

It will take the snail 9.6 minutes to travel 24cm.

What are the exact solutions of x^2 = 5x + 2?
aleksandrvk [35]
Move everybody to one side
minus 5x+2 both sides
x^2-5x-2=0
use quadratic formula where
if you have
ax^2+bx+c=0
x=\frac{-b+/- \sqrt{b^{2}-4ac} }{2a}

1x^2-5x-2=0
a=1
b=-5
c=-2

x=\frac{-(-5)+/- \sqrt{(-5)^{2}-4(1)(-2)} }{2(1)}
x=\frac{5+/- \sqrt{25+8} }{2}
x=\frac{5+/- \sqrt{33} }{2}

aprox
x=5.372281323 or -0.3722813233
