The two lizards in the United States are the gilamonster and the chuckwalla. The average Gila monster is 0.608 meter long. The average chuckwalla is 0.395 meter long. How many times as long is the Gila monster as the chuckwalla, to the nearest hundredth?

Answers

The Gila monster is approximately Ratio 1.54 times as long as the chuckwalla when their lengths are compared.

To find out how many times as long the Gila monster is than the chuckwalla, we divide the length of the Gila monster by the length of the chuckwalla. This gives us a ratio that expresses the relative size of the two species.

So, using the given average lengths:

Gila monster length: 0.608 meters

Chuckwalla length: 0.395 meters

We divide the length of the Gila monster by the length of the chuckwalla:

Ratio = Gila monster length / Chuckwalla length = 0.608 meters / 0.395 meters = 1.54 (rounded to the nearest hundredth)

So, the Gila monster is approximately 1.54 times as long as the chuckwalla.

This is easy, you just divide 0.608 by 0.395, which equals 1.54 (rounded to the nearest hundredth). So, the Gila monster is about 1.54 times as long as the chuckwalla.

The sum of two consecutive odd numbers is 156 . What are the numbers

Answers

You would first write out: x+x+2= 156. Once you've got that, you add the 2 x's together and get: 2x+2=156. Now that you have them together, subtract 2 on both sides and you get: 2x=154. Solve for x by dividing 2 on both sides and you get 77 as x. Now, you would know the 2 numbers, which would be 77 and 79.
I hope this helps. :-)
consecutive odd numbers are represented as
x=first odd
x+2=second odd
and so ono

so the 2 numbers are
x and x+2
so
x+x+2=156
subtract 2 from both sdies
2x=154
divide by 2
x=77


the first number=77
x+2=second number=79

the numbers are 77 and 79
