500m:2km (change km to m)
500m:2000m (divide by 100)
5m:20m (divide by 5)
1m:4m
The answer is 13. 13 times
Right angle is the answer I think ( not sure though )
25 less than 5 = 5 - 25
the answer is A. 5 - 25
Less than = subtraction
so the equation means 5 -(less than) 25
the correct answer is 5 - 25
Hope this helps!
In five quarts, we have 2 quarts of acid and 3 quarts of water
total = (2 + 3) = 5 quarts
concentration = 2 / 5
We want a 30% concentration
total volume = 2 + x
.30 = 2 / (2+x)
.6 + .30 x = 2
.30x = 1.4
x = 4.66666 gallons of water
(or we need to add 1.666666 gallons of water)
Double Check:
acid concentration = 2 / (2 + 4.666666)
acid concentration = .30
