48 ÷ 80 = .6
60/100 = 6/10 = 3/5
3/5 of every gallon is green
Answer:
3/9 is 1/3 because if you simply by 3, it will be 1/3 of 9
Let 
be the number of students who eat cauliflower.
Therefore, 
.
Let 
be the total number of students surveyed.
Therefore, 
Thus, 
Now, for 90% confidence level, from the table we know that 
.
The formula for the interval range of proportion of students is :
Plugging in the values we get:
Thus, Jane is 90% confident that the population proportion p, for students who eat cauliflower in her campus is between 5.398% and 15.114% (after converting the answer we got to percentage).
The area of the blanket - 24 ft²
length being longer than the width means that blanket is a rectangle
width of the blanket = x
length of blanket = x +2
area = length * width
area = x * (x+2)
= x² + 2x
since area = 24
x² + 2x = 24
x² + 2x - 24 = 0
we have a quadratic equation and we need to now solve for x
x² + 6x - 4x - 24 = 0
x (x + 6) - 4(x + 6) = 0
(x-4) (x+6) = 0
x-4 = 0 or x + 6 = 0
x = 4 or x = -6
x could be either 4 or -6. since dimensions cannot have negative values,
x ≠ -6
therefore x = 4
width = 4 ft
length = 6 ft
Answer:
work done against friction: (a) if a body is moved horizontally against the frictional force this type of work is work done against friction.
(b) for example sliding a box and rolling a drum
work done against gravity: (a) if a body is moved vertically upwards against the gravity of the earth, this type of work is work done against gravity
(b) for example lifting and throwing of a body upward
