Answer:
The average speed is 24 km/h less than the top speed of the lorry.
Step-by-step explanation:
The top speed of the lorry is the highest speed reached during transit, while its average speed is the mean speed attained
Given:.
Top speed of the lorry = 90 km/h
Average speed of the lorry = 66 km/h
Then,
The difference between the speed reached = top speed - average speed
= 90 - 66
= 24 km/h
Therefore, the average speed is 24 km/h less than the top speed of the lorry.
Answer: Last option.
Step-by-step explanation:
In order to estimate the percent "n" of a number"x", you need easy numbers to work with, therefore you can round "n" and "x" up or down; but it is important to remember that this estimation does not give you an exact value.
You can observe that Sergei's first step was to round 149% and 67 up, getting this result:
To verify if this estimate is less or greater than the actual answer, we can find the actual answer. This is:
Therefore, we can conclude that<em> the estimate is greater than the actual answer because the percent and the number were both rounded up</em>.
Remember your formula is 180(n-2) where n=number of sides. So start out by dividing by 180, then add 2 to get the sides.
A) Volume = l * w* h --> V = 7 * 5 * 4 --> V = 140 units³
B) 140 units³: Prism B has the same length, width, and height as A, just rotated.
C) As long as the tree numbers' product is 140 units³, it works.
Prism C: 140 * 1 * 1
Prism D: 14 * 2 * 5
