Answer:
56.25
Step-by-step explanation:
The number you need to add to both sides to complete the square needs to be calculated by doing (
)². So, in this problem, b= -15.
-15/2 = -7.5, and -7.5² = 56.25. This is the number you will add to complete the square
Answer:
V = 90 cm^3
Step-by-step explanation:
The volume is given by
V = Bh
where B is the area of the base and h is the height
The base is the two sides that are identical, which is the triangle
B = 1/2 bh
= 1/2 (4*3)
= 1/2 (12)
= 6
Substituting into the volume equation, where h = 15
V = 6*15
V = 90 cm^3
Answer: in explanation
Step-by-step explanation
Sandi can perform 1/9 of the task in a day
Eva can perform 1/5 of the task in a day
Working together, they can perform
1/9 + 1/5 of the task per day
= 5/45 + 9/45 = 14/45 of the task in a day
or 45/14 days in the task = 3.2 days
So
It would take about 3.2 days to complete the task working togethe
