If the average speed of a garden snail is 0.025 miles per hour and one inch is approximately 2.54 centimeters, how many minutes would it take a garden snail to travel one meter? round the answer to the nearest tenth.
a) 1.4 minutes
b) 1.5 minutes
c) 2.1 minutes
d) 2.6 minutes

B

Step-by-step explanation:

First, convert speed in miles per hour to inches per second.

Use

1 mile = 63,360 inches

1 hour = 3,600 seconds

Then

Now, use the fact that

1 inch = 2.54 cm, so

Finally,

Distance = 1 m = 100 cm

Speed = 1.1176 cm/sec

Time = ? sec

Hence,

y=mx+b

step-by-step explanation:

m is slope, b is y-intercept

x= -3 and

step-by-step explanation:

to find the roots of a cubic, use division or factoring to find the factors then set equal to 0. as this is a difference of cubes, it factors into

where a is the cube root of .

here   this is 27 and the cube root of 27 is 3. so we write using the form:

.

set each factor to 0 and solve for x.

x-3=0

x=3

the quadratic expression does not factor and must be solved using the quadratic formula.

where a = 1, b=3, and c=9

this cubic has two complex roots.
