Correct question is;
Tanya walked for 17 minutes from her home to a friend that lives 1.5 kilometers away. D(t) models Tanyas remaining distance to walk in kilometers, t minutes since she left home. What number type is more appropriate for the domain of d?
Answer:
0 ≤ t ≤ 17 ; (0, 17)
Step-by-step explanation:
We are told that she has walked for 17 minutes from her home to a friend that lives 1.5 kilometers away.
Now, we want to find the domain of numbers that shows her remaining distance.
Since she spent 17 minutes, then it means in modeling remaining distance it could be from 0 to 17 minutes as the case may be. Thus, the domain can be written as;
0 ≤ t ≤ 17 ; (0, 17)
Just take 9/9-4/9=5/9, we get 9/9 because that is how much fruit punch that there was when the container was full. Enjoy!=)
7b - 2b + 3 - 1 = 0
(7b - 2b) = 5b
3 - 1 = 2
Thus:
5b + 2 = 0
5b = -2
b = -2/5 = -0.4
Answer:
see explanation
Step-by-step explanation:
Since the triangles are similar then the ratios of corresponding sides are equal, that is
= , substitute values
= ( cross- multiply )
4XZ = 144 ( divide both sides by 4 )
XZ = 36 cm
-------------------------------------------------------
Also
= , substitute values
= ( cross- multiply )
16BC = 192 ( divide both sides by 16 )
BC = 12 cm
