Hello there! Your answer would be '<em>the actual distance between the cities is 320 kilometers</em>'.
Okay, so to solve this, we can use unit rates. We know that for every one centimeter we have eighty kilometers. So, whatever we multiply the centimeter value by, we can multiply the kilometer value by the same number and get our answer.
So if the centimeter value is 4, multiply the kilometer value by 4.
80 x 4 = 320
This means that the cities are 320 kilometers apart, and you have your answer!
Hope this helps, and have a great day!
Answer:
Paul should give 18 teaspoons of medicine to his dog.
Step-by-step explanation:
It is stated in the question that for every 12 pounds, 3 teaspoons of medicine is to be given to the dog.
This implies that:
12 pounds = 3 teaspoons
1 pound = 3/12 teaspoons
= 1/4 teaspoons <em> ( by cross multiplication )</em>
<em />
<h3>72 pounds = 1/4 * 72 teaspoons</h3><h3> = 18 teaspoons</h3><h3 />
Hence, Paul should add 18 teaspoons of medicine to his dog's food.
Answer:
x ≈ 1091.63
Step-by-step explanation:
Using the rule of logarithms
x = n ⇔ x = 
note that ln x is to the base e
Given
ln(x + 5) = 7, then
x + 5 =
( subtract 5 from both sides )
x =
- 5 ≈ 1091.63 ( nearest hundredth )
The 1.8 s is the time for the signal to reach the ocean floor and return to the ship so the time to reach ocean floor = 1.8 / 2 = 0.90 seconds.
depth of ocean = speed * time
= 1498 * 0.90 = 1348.2 m Answer
