Answer:
<h2><u><em>
342 m</em></u></h2>
Step-by-step explanation:
Calculate 50% of 684 m.
Give your answer in metres (m).
50% = 1/2
so
684 : 2 = 342 m
30000 is the answer as it is ajove 20000 in comparison to rounding down
Answer:
(x+3)²-11=0
Step-by-step explanation:
0=9(x2+6x)-18
0= 9x² +54x-18
0= 9( x²+6x-2) taking 9 common
0= x² +6x-2 (breaking the mid term to find the second element of the square
0 = (x)² +2(x)(3) +(3)² -2 -9 adding and subtracting the second element
0= (x+3)² -11 summing up
Answer:
491 mg per dose
Step-by-step explanation:
1 kg ≈ 2.2 lbs
81/2.2 36.82 kg
40*36.82 ≈ 1472.8 mg/day
1472.8/3 ≈ 490.93
to the nearest mg = 491 mg per dose
Answer:
Step-by-step explanation:
Given Annabella time for a race is 24.2 seconds, if another runnee's time was 6.43 seconds faster, then the time taken for another runnee's time will be 24.2 - 6.43 = 17.77secs.
Let a variable X be the difference between annabelle's time and the other runners time.
X = annabelle's time - other runners time.
X = 24.2 - (24.2 - 6.43)
X = 24.2-24.2+6.43
X = 6.43seconds
Hence the expression between annabelle's time and the other runners time is X = 24.2 - (24.2 - 6.43)
<em>The difference between annabelle's time and the other runners time is 6.43seconds</em>
