Answer:
The answer is 4
Step-by-step explanation:
convert bot fractions into a decimal
4 1/2 = 4.5 1 1/8 = 1.125
4.5 divided by 1.125= 4
12. since the straws are 4 inches long and she wants to cut them into 1/2 in you would get eight 1/2 pieces on that one straw but since she has two straws she has sixteen 1/2 pieces so no she does not have enough to cut twenty 1/2 pieces
Y = yo + Vot - (gt^2)/2
y = 10 + 27t - 16.087t^2 [I used g = 32.174 ft/s^2]
You can find y with the quadratic formula or probe with the different times given.
I tried with t = 2 s and found
y = 10 + 27(2) - 16.087 (4) = 10 + 54 - 64.348 = -0.348
Then that is the answer, t = 2s.
Acute angle bc its the smallest angle
