A deciliter is how many times larger than a millimeter?
jarptica [38.1K]
Milliliter  centiliter  deciliter  liter   dekaliter   hectoliter kiloliter

All related by 10's   every move to the right is 10x larger than the one to its left

Since deciliter is two steps away from milliliter it is 10 x 10 or 100 times as large.

If the question is meant to be a trick then the answer is 99x larger.  

It should read "A deciliter is how many milliliters"  ofr "a milliliter is how much of a deciliter?"
 Once you say larger than you could be confusing subtraction with multiplication.  How much larger than 30 is 3?  Answer is clearly 27.  How many times as large as 3 is 30?  Answer is clearly 20. How many times larger than 3 is 30?  Hmmmm?  Which one of the two does he mean?
I am sure your teacher meant you to consider multiplication, but just in case, I included the "trick" answer.

Resonances of the ear canal lead to increased sensitivity of hearing, as we’ve seen. Dogs have a much longer ear canal—5.2 cm—th
krek1111 [17]

Answer:

B. 1700 Hz, 5100 Hz

Explanation:

Parameters given:

Length of ear canal = 5.2cm = 0.052 m

Speed of sound in warm air = 350 m/s

The ear canal is analogous to a tube that has one open end and one closed end. The frequency of standing wave modes in such a tube is given as:

f(m) = m * (v/4L)

Where m is an odd integer;

v = velocity

L = length of the tube

Hence, the two lowest frequencies at which a dog will have increased sensitivity are f(1) and f(3).

f(1) = 1 * [350/(4*0.052)]

f(1) = 1682.69 Hz

Approximately, f(1) = 1700 Hz

f(3) = 3 * [350/(4*0.052)]

f(3) = 5048 Hz

Approximately, f(3) = 5100 Hz

A truck of mass 500kg moving at 4m/s collides with another truck of mass 1500kg moving in the same direction at 2m/s. What is th
VMariaS [17]

Answer:

m1u1+m2u2=(m1+m2)v.

500×4+1500×2=(500+1500)V.

2000+3000=2000V.

5000=2000V.

V=2.5m/s

Which response is the least effective when confronted with trying drugs or alcohol? "I'd rather be in control of what I do."
SVEN [57.7K]

Answer:

The least effective answer would be "It's okay to lose control every once in a while."

Explanation:

This answer would make it seem like you are either already on drugs or you are willing to try them, which i assume in this case, you are not.
