Answer:
67.5
Step-by-step explanation:
- When you calculate the 10% of AED75, it is equal to AED7.5
- Then you subtract AED7.5 from AED75 which is AED67.5
From question,
lacy learned 34 recipes in 17 weeks,
so in 1 week she learns = 34/17 =2 recipes,
hence she learns 40 recipes in
= 40*2
=80 recipes.
By using the concept of uniform rectilinear motion, the distance surplus of the average race car is equal to 3 / 4 miles. (Right choice: A)
<h3>How many more distance does the average race car travels than the average consumer car?</h3>
In accordance with the statement, both the average consumer car and the average race car travel at constant speed (v), in miles per hour. The distance traveled by the vehicle (s), in miles, is equal to the product of the speed and time (t), in hours. The distance surplus (s'), in miles, done by the average race car is determined by the following expression:
s' = (v' - v) · t
Where:
- v' - Speed of the average race car, in miles per hour.
- v - Speed of the average consumer car, in miles per hour.
- t - Time, in hours.
Please notice that a hour equal 3600 seconds. If we know that v' = 210 mi / h, v = 120 mi / h and t = 30 / 3600 h, then the distance surplus of the average race car is:
s' = (210 - 120) · (30 / 3600)
s' = 3 / 4 mi
The distance surplus of the average race car is equal to 3 / 4 miles.

Critical Value of 
Generally the equation for momentum is mathematically given by
The width of the enlarged photo is 9 inches.
Given:
Original length = 2 inches
Original width = 1 inch
Extended length = 18 inches
Extended width = ?
2:1 = 18:x
2x = 1*18
2x = 18
2x/2 = 18/2
x = 9 * extended width.
to check:
2:1 = 18:9
2*9 = 1*18
18 = 18
