We know that in one minute the toddler is 2(270)=540 feet and mother is 580 so less than 1 minute
its the first option.
tiles of X and tiles of 1 are different
3 tiles of "X" = 3X
3 tiles of " 1 " = 3
option 3 does not mean 3X, it just means 3X + 3
Answer:
C
Step-by-step explanation:
according to sine rule,
sin(30)/8=sin(x)/11
solving above equation will give
x=43.3
Answer:
b^2-4b+3=0
b²-3x-b+3=0
b(b-3)-1(b-3)=0
(b-3)(b-1)=0
either
b=3 or b=1
.
2n^2 + 7 = -4n + 5
2n²+4n+7-5=0
2n²+4n+2=0
2(n²+2n+1)=0
(n+1)²=0/2
:.n=-1
.
x - 3x^2 = 5+ 2x - x^2
0=5+ 2x - x^2-x +3x^2
0=5+x+2x²
2x²+x+5=0
comparing above equation with ax²+bx +c we get
a=2
b=1
c=5
x={-b±√(b²-4ac)}/2a ={-1±√(1²-4×2×5)}/2×1
={-1±√-39}/2
Step-by-step explanation:
If A=650+135N; and B=585N,
then A+B= 650+135N+585N=650+620N
T=720N+650
