Answer: 17 patients stayed for longer than 10 minutes.
Step-by-step explanation:
Let x represent the number of patients that stayed for longer than 10 minutes.
The doctor charges $21.80 for consultations that last less than 10 minutes and $27.50 for those that last longer than 10 minutes. Yesterday the doctor earned $1077.90. If 28 consultations lasted less than 10 minutes, it means that
28 × 21.80 + x × 27.50 = 1077.90
610.4 + 27.5x = 1077.9
27.5x = 1077.9 - 610.4
27.5x = 467.5
x = 467.5/27.5
x = 17
The rule for rounding is that if the fraction is less than 1/2, we round down; and if the fraction is more than 1/2, we round up.
Because 5/6 is a greater fraction than 1/2, we must round the existing whole number (8), up.
8 5/6 rounded to the nearest whole number is 9.
Answer:
48 cubes are needed to fill the prism
Step-by-step explanation:
To solve this problem we first have to calculate the volume of the cube
1/2 units= 0.5 units
To calculate the volume of a cube we have to use the following formula:
v = volume
s = side = 0.5 u
v = s * s * s
we replace the values that we know
v = 0.5 u * 0.5 u * 0.5 u
v = 0.125 u³
The volume of the cube prism is 0.125 u³
Now we have to divide the volume of the prism by the volume of the cubes
6 u³ / 0.125 u³ = 48
48 cubes are needed to fill the prism
