Write a proportion
centimeters / kilometers
1.5 / 45 = 0.8 / x
cross multiply
(1.5 * x ) = (45 * 0.8)
1.5x = 36
divide both sides by 1.5
x = 24
The actual distance between the two points is 24 kilometers.
Hope this helps
Using the quadratic equation would be the easiest
The correct answer is: 17280 <span>
cubic inches</span>
Explanation:As we are going to convert bigger unit (feet) into small unit (inches), we will need to multiple 10 with
as there are 12 inches in 1 foot and the unit is in cubic form, therefore, we would need to take the cube of 12. Mathematically we can write it as:
<span>cubic inches
Hence the correct answer is </span>17280 cubic inches.
Right answers: <span>A hot-air balloon ascends 2000 ft from the ground and then descends 2000 ft.

Answer: 6 people ordered for the lobster dinner.
2 people ordered for the steak dinner.
Step-by-step explanation:
Let x represent the number of people that ordered the lobster dinner.
Let y represent the number of people that ordered the steak dinner.
A family of 8 went out to dinner. This means that
x + y = 8
Each person either ordered the lobster dinner, which costs $25, or the steak dinner which cost $20. The total cost of all the meals is $190. This means that
25x + 20y = 190 - - - - - - - - - -- -1
Substituting x = 8 - y into equation 1, it becomes
25(8 - y) + 20y = 190
200 - 25y + 20y = 190
- 25y + 20y = 190 - 200
- 5y = - 10
y = - 10/ - 5
y = 2
x = 8 - y = 8 - 2
x = 6
