3 1/2 ft = 3.5 ft
1 ft = 12 inches
3.5 ft = 3.5 * 1 ft = 3.5 * 12 inches = 42 inches
3 1/2 ft = 42 inches
All boxes must measure less tan 42 inches.
Only choice C has three measurements that are less than 42 inches.
Answer: C.
Yes................................
Answer:
118.25
Step-by-step explanation:
7c^2+5/4a-b if a=1, b= -5 and c=-4
7(-4)^2 + (5/4)+5
7*16 + 1.25 + 5
112 + 6.25
= 118.25
Complementary. They add to 90 (right angle). Supp. adds to 180 (straight angles).
The formula for the kinetic energy is:
Ke = 0.5mv^2
Where ke is the kinetic enrgy
M is the mass
V is the velocity
Ke = 0.5mv^2
12.5 = 0.5(1) v^2
Solve for v
V = 5 m/s
Potential energy, pe = mgh
Where m is mass
G is accelearation due to gravity 9.8 m/s2
H is the height
98 = (1)(9.8) h
H = 10 m
