Step-by-step explanation:
30 mph would be a safe speed for you to drive.
Collisions are much more likely to occur when one driver travels greater speedy or more slowly than the alternative motors on the road. You have to input a throughway at or near the velocity of visitors except if the speed of site visitors exceeds the prison speed restrict.
A pedestrian has a 90 percent threat of survival if hit by a vehicle transferring at 30 km ph (18.64 mph). This decreases to 70 percent at 40 kmph (24. eighty five mph) and much less than 20 percent at 50kmph (31 mph). driving at decreased speeds also enables drivers to stop within a shorter distance.
Retaining high speeds on highways is straightforward, as roads are wider and traffic is usually mild. If there are signs that show a pace restriction of 80kph, use them as a guide and stick near them. it's also an excellent exercise to assess road situations and set your pace thus.

To find the volume of a rectangular prism, like this one, we take the measure of the Width, Length, and Height and multiply them together. So the answer is: 4*4*8. 4*4=16, and 16*8=128, so the answer is 128 Cubic Feet.
Answer:
126
Step-by-step explanation:
Let x be the missing length
The triangles are similar:
● UE/140 = 45/x
From the graph we deduce that:
● UE = 140 - 90 = 50
Replace UE by its value
● 50/ 140 = 45/x
Switch x and 50
● x / 140 = 45/50
45/50 is 9/10 wich is 0.9
● x/140 = 0.9
Multiply 0.9 by 140
● x = 140 × 0.9
● x = 126
Answer:
(x + 2) (x + 1) thus b: is the Answer
Step-by-step explanation:
Factor the following:
x^2 + 3 x + 2
The factors of 2 that sum to 3 are 2 and 1. So, x^2 + 3 x + 2 = (x + 2) (x + 1):
Answer: (x + 2) (x + 1)
