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
Answer:
no
Step-by-step explanation:
3 is the x coordinate/ integer and -4 is the y coordinate and the integer so it wouldn't make sense
x= 3 is a solution
and id you don't understand the first thing i said watch this
#1. 3, - 4
#2. x= - 4
#3. substitute/replace the x with what the x coordinate is
#4. it will be 3= - 4
#5. as you can see the numbers don't equal each other so it's a no solution
Answer:
n = 25
Step-by-step explanation:
Add to both sides.
n = 17 + 8 = 25
Answer:
(x + 1)² + (y - 3)² = 8
Step-by-step explanation:
radius (r): √(1 - (-1))² + (1 - 3)² = √8 = 2√2
Formula for circle with center (h,k): (x – h)² + (y – k)² = r²
(x + 1)² + (y - 3)² = 8
