Answer:
Step-by-step explanation:
we know that 100 cm are equal to 1 meter
there are 4 "groups" of 25 cm in one meter
the worm needs 76 seconds to travel a meter, in case you need to know that
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:
12
Step-by-step explanation:
25%=1/4
of=*
3=1/4x
3 divided by 1/4 or 0.25 =12
So, to find the answer you'd first add up how many patients you have:
20+50+100 = 170.
In a fraction your total would go on the bottom. Then you'd take how many patients are taking a real drug, which is represented by 20+50 = 70. This number would go on top.
So, the probability of a patient NOT getting a placebo is 70/170. Simplified would be 7/17.
The answer is D. 7/17.
