A snail is moving along a path that is 4 meters long. The snail moves at an average rate of 3 3/10 inches per minute. Question 1
Troyanec [42]

Answer: The length of the path = 157 inches { approx}

Step-by-step explanation:

Given: The length of the path = 4 meters

1 meter = 100 centimeters

So 4 meters = 400 centimeters

Also 1 in. ≈ 2.54 cm

\Rightarrow\ 1 cm = \dfrac{1}{2.54}\ in.

Now, \text{ 400 centimeters}=400\times\dfrac{1}{2.54}\text{ inches}

=157.480314961\approx 157  \ \ \ \ \ \text{ [Rounded to the nearest inch.]}

Hence, the length of the path = 157 inches { approx}

UkoKoshka [18]

Answer:

Bobcats

Step-by-step explanation:

The wins-to-losses ratio for the Cougars is 12:10.  This can also be written as 12/10; writing this as a decimal, we would have 1.2.

The wins-to-losses ratio for the Bobcats is 20:10.  This can also be written as 20/10, which is the same as 2.0.

The wins-to-losses ratio for the Bulldogs is 8:5.  This can also be written as 8/5, which is the same as 1.6.

The wins-to-losses ratio for the Tigers is 3:5.  This can also be written as 3/5,l which is the same as 0.6.

The largest of these decimals is 2.0; this means the Bobcats have the greatest ratio of wins to losses.

A jacket that originally sold for $60.00 was on sale for 10% off. When it didn't sell after several weeks, the sale price was di
sammy [17]
The final price of the jacket was $32.40 after both the 10% and 40% discount. The total discount is NOT equal to a 50% discount. When 10% off, the price was $54, bringing the next 40% off to a whole different number, not necessarily off the original price.

I don't know if that makes sense to you, sorry xD
