Answer:
11
Step-by-step explanation:
The answer is 11 because 2x7=14+2x2=4. 14+4=18-1=17. 30-17= 11
Answer:
v = -2
Step-by-step explanation:
-9v – 9 = -27
add 9 to each side
-9v – 9+9 = -27+9
-9v = -18
divide by -9
-9v/-9 = -18/-9
v = 2
The plane from new york to london fly 515.2 km per hour compared to the plane from denver to hartford .
<h3>What is Ratio ?</h3>
Ratio is when a number is divided by any other number and written in the form p:q.
It is given in the question that
A commercial airplane broke a record when it traveled 5,540 kilometers from new york to london in 5 hours .
a different airplane traveled 2,964 kilometers from denver to hartford in 3 hours.
The airplane travelled 5,540 kilometers in 5 hours
In 1 hour , the commercial airplane covered 5540/5 = 1108 km.
In 1 hour , the other airplane covered 2964/5 = 592.8 km
Therefore the plane from new york to london fly 1108- 592.8 = 515.2 km per hour compared to the plane from denver to hartford .

Answer:
1:00 a.m. (and 3:00 a.m., and 5:00 a.m.)
Step-by-step explanation:
The problem is to find the least common multiple (LCM) of the barking intervals. One way to find the LCM is to find the product of the factors of the numbers.
... 5 = 5 . . . . a prime number
... 8 = 2³
... 12 = 2²×3
The factor 2³ is a multiple of the factor 2², so we only need 2³ in our final product.
The LCM is then ...
... 2³×3×5 = 120 . . . . minutes
