Answer:
12
Step-by-step explanation:
Average age of 5 boys = 11 year
Sum of age of 5 boys = 11*5 = 55
Age of sixth boy = 17 years
Sum of age of 6 boys = 55 + 17 = 72
Average age of 6 boys= 72/6 = 12
Answer:
1.88 inches
Step-by-step explanation:
The volume is the product of length, width, and height. If w represents the width of the box, then its length is 4w and its height is w+7. The volume is then ...
V = (4w)(w)(w+7)
We want to find the value of w that makes V=126. It is convenient to use the graphing calculator to look for zeros of a function, so we can write the equation as ...
V - 126 = 0
4w·w·(w+7) -126 = 0
The only positive solution to this equation is near w ≈ 1.883.
The width of the box is about 1.88 inches.

Attached is output from the DESMOS free graphing calculator. The ALEKS calculator requires a subscription. The method of solution is substantially the same, but requires a little more work on the ALEKS calculator to find the zero-crossing.
Step-by-step explanation:
the vertex is the point, where the parabola turns around. it is (depending on its orientation, if it is opening upwards or downwards) the maximum or the minimum of the curve.
so, as we can see on the grid, that point is x = -3, y = +1 = (-3, 1).
so, B is correct
Answer:
a
Step-by-step explanation:
So 6 shots equals 25% of the teams total shots(x).
So 6=0.25(x)
x=6/0.25
x=24
If the team made 62.5% of their shots, then they missed 100%-6.25%=37.5%
37.5% of 24= 24(0.375)=9
Hope this helps
