So 16=heads
18=tails
after you add some tails
18+x
ratio of heads to tails is 1:1.5
heads=16, didn't change
tails=18+x
so
1:1.5=16:18+x
fractionify
1/1.5=16/(18+x)
1/1.5=2/3
2/3=16/(18+x)
mutiply both sides by (3)(18+x)
2(18+x)=3(16)
36+2x=48
subtract 36 from both sides
2x=12
divide 2
x=6
6 tails added
total=heads+tails
heads=16
tails=18+6=24
total=16+24
total=40
6 tails added
40 total coins
1000, because if it’s number 0-9 you have 10 options for the first possible number, then multiply by 10 two more time for the second and third number .but if it’s wrong I’m srry rip ;P
Answer:
The distance between those points rounded to the nearest tenth is 5.1
Step-by-step explanation:
1. (x2-x1) = (-1 - 4) = -5
2. (y2-y1) = (4 - 3) = 1
3. (-5^)2 + (1)^2 = 25 + 1 = 26
4. √26 = √26
5. 5.099 ---> Rounded to the nearest tenth = 5.1
Answer:g = 50 g
Step-by-step explanation:
She used 60% more than required ⇒ she used (1+0.60)=1.60 times what was required.
x = grams required by the recipe
80 g = 1.60x
x = (80/1.60) g = 50 g
