Answer:
adding salt makes the water freeze slower and evaporate slower too.
Step-by-step explanation:
While pure water freezes at 0°C (32°F), salt water needs to be colder before it freezes and so it usually takes longer to freeze. The more salt in the water, the lower the freezing point.
Yes, angle B and angle D are equal, so it is true
Answer:
f(x) = (x - 10) (x + 10)
Step-by-step explanation:
The equation looks like the difference of squares so 5 and 20 are out
-10 x -10 = 100
-10 x 10 = - 100
so (x - 10) (x + 10)
A1 = 4
a2 = 5a1 = 5 x 4 = 20
a3 = 5a2 = 5 x 20 = 100
a4 = 5a3 = 5 x 100 = 500
a5 = 5a4 = 5 x 500 = 2,500
Tn = ar^(n-1); where a = 4, r = 5
Tn = 4(5)^(n-1) = 4/5 (5)^n
Explicit formular is Tn = 4/5 (5)^n
Recursive formular is
Answer:
The fraction of red guppies = 1/10
Step-by-step explanation:
Garys fish are guppies = 3/5
1/6 of them are red.
Number of red guppies = ?
To find the fraction of red guppies, we will multiply both the fractions.
Number of red guppies = 3/5 * 1/6
Number of red guppies = 3/30
Number of red guppies = 1/10
Thus the fraction of red guppies = 1/10 ....
