The number three that is being added to the fraction goes on the x axis determiner where you start. The u use the fraction and -3 is the y and -2 or two is the x
Answer:
between 8 and 9
Step-by-step explanation:
The square of 8 is 64, which is less than 78.
The square of 9 is 81, which is more than 78.
The square root of 78 will lie between 8 and 9 on the number line.
_____
√78 is near 8.832
Answer:
The whole number dimension that would allow the student to maximize the volume while keeping the surface area at most 160 square is 6 ft
Step-by-step explanation:
Here we are required find the size of the sides of a dunk tank (cube with open top) such that the surface area is ≤ 160 ft²
For maximum volume, the side length, s of the cube must all be equal ;
Therefore area of one side = s²
Number of sides in a cube with top open = 5 sides
Area of surface = 5 × s² = 180
Therefore s² = 180/5 = 36
s² = 36
s = √36 = 6 ft
Therefore, the whole number dimension that would allow the student to maximize the volume while keeping the surface area at most 160 square = 6 ft.
ANSWER: Between the 7 and the 8
STEP-BY-STEP EXPLANATION:
_____
1.7 | 45.78
We want to make the 1.7 into a whole number. We do this by moving the decimal 1 space to the right and since we move the decimal one space on the divisor, we need to move the decimal 1 space on the dividend.
so your problem would now be :
______
17 | 457.8
