Answer: The perimeter is 20 cm
Step-by-step explanation: The top and bottom are same length, so 6+6, and the sides are the same length, so 4+4 don’t forget it’s cm and it becomes 20 cm.
PERIMITER = ADDING ALL SIDES
AREA = MULTIPLYING
Answer:
EF = ~3.8
Step-by-step explanation:
Apply the sine theorem:
EF/sinD = DE/sinF
=> EF = DE*(sinD/sinF)
= 3*(sin75/sin50)
=3.78 = ~3.8
Hope this helps!
Answer:
I think it is the daughter
Step-by-step explanation:
only because she is only 115 m away from home plate itself and the father is 132m away which is going to take some for the sound waves to travel and for anyone to hear . Also if you don't believe me, more of an explanation is ...
Kilometers are 1,000 times larger than meters. The meter is the base unit for measuring length or distance in the metric system.
132 km x 1,000 = 132,000m and 115 is already in meters now i think that is simple enough of an explanation. Your welcome. I know I'm right
Answer:
3rd degree trinomial
Step-by-step explanation:
the highest power is 3 and there are 3 terms so its a 3rd degree trinomial
T=time
d=st
r=train speed
p=plane speed
<span>160=rt
</span><span>720=pt
speed of plan is 20kmph less than 5 times speed of train
p=5r-20
we notice that 160 times 4.5=720
times first equaton by 4.5
720=4.5rt
720=pt
set equal
4.5rt=pt
divide both sides by t
4.5r=p
sub </span><span>p=5r-20 for p
4.5r=5r-20
minus 4.5r from both sides
0=0.5r-20
add 20 to both sides
20=0.5r
times 2 both sides
40=r
sub back</span><span>
p=5r-20
p=5(40)-20
p=200-20
p=180
plane is 180kmph
train is 40kmph
</span>
