To answer, first, convert the given velocity in km/h to m/s as shown below,
(144 km / hr) x (1000 m / 1 km) x (1 hr / 3600 s) = 40 m/s
The acceleration (a) is solved by through the equation,
a = (Vf - Vi) / Δt
where Vf and Vi are final and initial velocities, respectively and Δt is change in time. Substituting the known values,
a = (0 - 40 m/s) / 12 s = -3.3 m/s²
Thus, the answer to this item is letter B.
Answer:
About 33% of students prefer chocolate icecream
Step-by-step explanation:
The actual percentage would be 35%, but none of the other answers are close enough to correct, so I'd have to say the bottom one.

Answer:
=<u>peanut butter cookie batches require more sugar</u>
Step-by-step explanation:
chocolate chip cookies:
3 1/4 / 2 1/2
<u>7 </u> / <u>5</u> = <u> 7 </u> x <u> 2 </u> = <u> 7 cups</u>
4 2 4 5 10
peanut butter cookies:
1 1/4 / 1 3/4
<u>5</u> / <u>7</u> = <u>5</u> / <u>4</u> = <u> 5 cups</u>
4 4 4 7 7
compare cups
<u> 7 </u> , <u> 5 </u> = <u> 49 , 50 </u>
10 7 70
=<u>50</u> = <u>5</u> = peanut butter cookie batches require more sugar
70 7
The answer to this question is C=6
