Answer:
Total length of the first swing=64 m
Step-by-step explanation:
The total length of all four swings can be expressed as;
Total length of all 4 swings=Length of first swing+length of second swing+length of third swing+length of fourth swing
where;
Total length of all 4 swings=175 m
Length of first swing=x
Length of second swing=75% of length of first swing=(75/100)×x=0.75 x
Length of third swing=75% of length of second swing
Length of third swing=(75/100)×0.75 x=0.5625 x
Length of fourth swing=75% of length of third swing
Length of fourth swing=(75/100)×0.5625 x=0.421875 x
replacing;
Total length of all 4 swings
175=x+0.75 x+0.5625 x+0.421875 x
2.734375 x=175
x=175/2.734375
x=64
Total length of the first swing=x=64 m
I believe in standard form this would be 31/2 + 27i/2
Answer:
I think it's A
Step-by-step explanation:
Answer:
a°=79°[alternate angles]
c°=83°[alternate angle]
a° +d°=180°[straight angle]
79°+d°=180
or,d°=180-79
so,d°=101°
Now,
b°+c°=170°[sum of straight angle]
b°+83°=180°
b°=180°-83°
so,b°=97°
Answer:
100
Step-by-step explanation:
sqrt[y] = 10
Apply both side a ^2
then
y = 100
