Subtract what Megan ate from the whole.
4/4-3/4 = 1/4.
Megan did not eat 1/4th of the cookie
d₁ = -16t² + 122t
d₂ = -16t² + 84t
d = d₁ - d₂
d = -16t² + 122t - (-16t² + 84t)
d = 38t
After five seconds, t=5,
d = 38(5) = 190
Answer: 190 feet
Answer:
Perimeter = 32.3
Area = 95.24
Step-by-step explanation:
Given:
△ABC, m∠A=60°
m∠C=45°, AB = 9
To find:
Perimeter of △ABC
Area of △ABC
Solution:
Using angle sum property in a triangle:
m∠A + m∠B + m∠C = 180°
m∠B = 180° - 45° - 60° = 75°
As per Sine Rule:
Where
is the side opposite to 
is the side opposite to 
is the side opposite to 
Perimeter of △ABC = AB + BC + AC = 9 + 11.08 + 12.22 = <em>32.3</em>
<em></em>
Area of a triangle is given as:
To determine the answer, we need to express the fractions into its decimal counterparts. 3/5 is equal to 0.6 therefore it is closest to 0.5 while 1/10 is equal to 0.1 therefore it is the last option. Hope this answers the question. Have a nice day.
