[7-(5-6(2)]+4+2
[7-(-1(2)]+4+2
[7- (-2)]+4+2 = [7+2]+4+2
9 + 4 + 2 = 15
Answer: 800 miles
Step-by-step explanation:
Let the actual distance between City C and City D be represented by x.
The information given in the question can be formed into an equation as:
1.8 feet / 2.88 feet = 500 miles / x
Cross multiply
1.8 × x = 500 × 2.88
1.8x = 1440
x = 1440/1.8
x = 800
Therefore, the actual distance between City C and City D is 800 miles.
Answer: 13
Step-by-step explanation:
add 21 both sides
divide both sides by 7
So more than 13 cars

Answer:
δx=0.035 m
Step-by-step explanation:
We use the expression of the uncertainty of x:
δx = (x/(vo cosθ))*sqrt((cosθ)² (δV₀)²+(V₀ sinθ)²(δθ)² )
First of all, we need to identify δV₀ and δθ. In our case δV₀ = 0.002 m/s and δθ = 0.0175 rad.
Remember: 1° = 0.0175 rad. This is very important to get the right answer here.
Now, we just need to replace the values we have into the equation δx:
δx = (0.5/(3.49*cos(76)))*sqrt((cos(76))²*(0.02)²+(3.49*sin(76))²*(0.0175)²)
δx = 0.035 m.
Have a nice day!
