Answer:
8
Step-by-step explanation:
2g = 3 + 13
2g = 16
g = 16/2
g = 8
Answer:
9 cm.
Step-by-step explanation:
Let x be the number of hours.
We have been given that after a winter storm, the depth of the snow on cherry street was 10 cm. Then, the snow started melting at a rate of
, so the snow melted in x hours will be
.
Since initially there was 10 cm of snow, so the depth of snow after x hours will be:

To find the depth of snow after 3 hours we will substitute
in our expression.



Therefore, the depth of the snow on cherry street after 3 hours will be 9 cm.
Answer:
A. 7
Step-by-step explanation:
Since the triangle sides are not defined, therefore let the base side have the 12 unit and one of the slant side be 7 unit.
Therefore height of the triangle, h can gotten from the Pythagoras theorem as thus:
7² = (12/2)² + h²
49 = 36 + h²
h² = 49 - 36 = 13
h = √13
knowing the height of the triangle, we can apply same rule to the other unknown slant side, x as thus:
x² = (12/2)² + h²
x² = 36 + 13 = 49
x = √49
x = 7
