Answer:
The scale used by Sarah is 1 to 43.2 inches ( drawing to actual)
Step-by-step explanation:
Here, we want to know the scale used for the drawing of the Dinosaur by sarah.
The actual height of the Dinosaur is 9 feet, but in her drawing she represented the height by 2.5 inches( 2 1/2 is same as 2.5 inches)
Mathematically, we know that 1 foot is 12 inches;
So the actual height of the Dinosaur is 9 * 12 = 108 inches
So practically, what she has done is to represent a height of 108 inches by 2.5 inches
So the scale factor used will be;
108/2.5 = 43.2
The scale used is 1 to 43.2 or simply 1:43.2 to represent the drawing to the actual
Answer:
Karl prepared 30 liters in 5 hours
Step-by-step explanation:
The total amount of juice Karl prepares per unit time can be expressed;
T=U×h
where;
T=total number of liters of juice prepared
U=number of liters prepared per unit time
h=number of working hours
In our case;
T=12 liters
U=U
h=2 hours
replacing;
12=U×2
2 U=12
U=12/2
U=6 liters per hour
The unit rate=6 liters per hour
Solving for 5 hours
Total quantity of juice prepared=Unit rate×number of hours worked
where;
Unit rate=6 liters per hour
Number of hours worked=5 hours
replacing;
Total quantity of juice prepared=(6×5)=30 liters
Karl prepared 30 liters in 5 hours
