Answer:
15
Step-by-step explanation:
Square root of 5=√5
Square of the square root=(√5)^2
=5
Square root of 3=√3
Square of the square root=(√3)^2
=3
So (square root of 5)^2×(square root of 3)^2
5×3
15
Therefore the final answer is 15
Answer:
115
Step-by-step explanation:
angle DEF is an inscribed angle and arc DF is the arc it intercepts
if you didn't know an inscribed angle is equal to half the measure of the arc it intercepts
Hence angle DEF = 1/2 of arc DF
If arc DF = 230 then angle DEF = half of 230 or 230/2
230/2=115
Hence angle DEF = 115
Work= forcexdistance
force=55x10(or 9.8 depending on which gravitational field strength you use)
force= 550N
work = 550x0.2
work= 110J
six steps=110x6=660J
Answer:
Step-by-step explanation:

HIGH SPEED= 40*30=1200 cm
low speed= 25*51=1275 cm
total= 1200+1275=2475 cm
