Answer:
ITS 4 CM
Step-by-step explanation:
17/20 or 0.85 is the answer
Celeste is 30 and Beth is 25
let x be Celeste's age now then Beth is x - 5
next year they will be 1 year older
Celeste's age will be x + 1 and Beth will be x - 5 + 1 = x - 4
the sum of their ages is therefore
x + 1 + x - 4 = 57
2x - 3 = 57 ( add 3 to both sides )
2x = 60 ( divide both sides by 2 )
x = 30
Celeste is 30 and Beth is 30 - 5 = 25
After all 20 tosses of the coin, a tail was recorded 11 times. We can write this as 11/20.
To convert this into a decimal, we simply multiply the numerator and denominator by 5 so that the fraction is out of 100, giving us 55/100.
When we do the sum of 55 ÷ 100, we get the answer of 0.55.
I hope this helps!
