Step-by-step explanation:
Given
Barry wants to make a drawing i.e. half the size of original
The length and width of the original drawing are 11 inches and 7 inches respectively.
So, the intended drawing is obtained by multiplying the original dimensions by 
The length of barry's drawing is
The breadth of barry's drawing
Answer:
50%
Step-by-step explanation:
The question asks who has taken fewer than 19 courses.
So first we look at how many are fewer than 19.
There are 4 that are fewer than 19: 12, 9, 5, 17

To find the percentage you...
Answer:
14 questions correct
Step-by-step explanation:
x/20 *100 = 70
so x/ 20 = 70/100(0.7)
x/20 = 0.7
x = 0.7*20
x =14
Answer: B 0.5 kWh per day
Step-by-step explanation:
Since the graph represents the function where electricity usage in kilowatts per hour of a clock radio varies directly with the number of days it is plugged into the wall current
The constant of variations will be the gradient ( slope ) of the graph.
Gradient = (Y2 - Y1)/(X2 - X1)
Where X1 = 2, X2 = 6, Y1 = 0.5, Y2 = 1.5
Substitute all the values into the formula
Gradient = (1.5 - 0.5)/( 6 - 4 )
Gradient = 1/2
Gradient = 0.5.
Therefore, a reasonable estimate of the constant of variation is 0.5 kWh per day
