Answer:
she colored in 60% of the paper blue and left 40% of the paper blank
Step-by-step explanation:
Answer:
Its a
Step-by-step explanation:
General equation for height, h
h = ut + 0.5gt^2
at t=1s, h = 76 feet
76 = u*1 + 0.5*a*1^2
76 = u + 0.5a
at t=2s, h = 144 feet
144 = u*2 + 0.5*a*2^2
144 = 2u + 2a
72 = u + a
Subtract 2 equations
0.5a = -4
a = -8
u = 80
So the equation,
h(x) = 80t + 0.5*(-8) t^2
h(x) = 80t - 4t^2
Answer:
k = 15
Step-by-step explanation:
12/4/5 = 4/5/4/5 k
15 = k
OR
5/4 (12) = 4/5 (5/4) k (multiply by the reciprocal)
15 = k
Step-by-step explanation:
x + x + x = 90°
3x = 90°
x = 90/3 = 30
x = 30°
now,
apply angle sum property to find the value of y
as, x = 30
so,
30 + 90 + y = 180
120 + y = 180
y = 180 - 120 = 60
y = 60° ans.
therefore, option B is correct
hope this answer helps you!
