Answer:
Kate has changed the unit of measurement from centimeters to decimeters.
Step-by-step explanation:
Tony measures a drum stick and the length is measured to be 31 centimeters.
Now, Kate converts Tony's measurements and gets 3.1.
Now, we know that 10 centimeters are equivalent to 1 decimeter.
Hence, 1 centimeter will be equivalent to 0.1 decimeters.
And, 31 centimeters will be equivalent to 31 × 0.1 = 3.1 decimeters.
So, Kate has changed the unit of measurement from centimeters to decimeters. (Answer)
A ratio shows us the number of times a number contains another number. Caitlin is right.
<h3>What is a Ratio?</h3>
A ratio shows us the number of times a number contains another number.
The ratio of the ages of Mandy and Sandy is 2:5. Therefore, the ratio will be,
M/S = 2/5
M = 2S/5
After 8 years, their ages will be in the ratio 1:2, therefore,
(M+8)/(S+8) = 1/2
2M + 16 = S + 8
2M - S = -16 + 8
Substitute the value of M,
2(2S/5) - S = -8
-0.2S = -8
S = 40
Now, if we substitute the value of S in the first ratio,
M/S = 2/5
M/40 = 2/5
M = 16
Now, if we take the difference in their ages the difference will be 24(40-16).
Since the difference is 24, we can conclude that Caitlin is right.
Hence, Caitlin is right.

Answer:
B
Step-by-step explanation:
-4:9 - This is half of the local gravitational constant, -9.8 m/s^2.
29:4 - The initial velocity of the arrow as it was shot upward was 29.4 m/s <u>(approximately 66 mph)</u>
You could give an example or research into previous hypothesis and tests for the topic you are on.
You could also link your hypothesis to something opposite. (Eg: If you were looking at ice melting you may want to also look at how it freezes, this would show that even though something happens it reverses to its original state, in this case water.)
