900
You work backwards;
Since he read 3/4 of the remainder that would be 75 x 4 because 75 was left after 3/4. You would get 300. Then, you would do 300 / (1/3), this is getting the final thing, equals 900.
Hope this helps!
The correct answer is Sanjay! :)
Explanation:
Joseph: 2/3
Sanjay: 5/7
2/3 and 5/7
14/21 and 15/21
Therefore, Sanjay is the answer.
Given:
A car traveled 150 km in 3 hour.
To find:
The unit rate.
Solution:
We have,
Distance = 150 km
Time = 3 hours.
In this case speed is the unit rate.
Substituting the given values, we get
Therefore, the unit rate is 50 km/h.
Answer:
n = 3.
Step-by-step explanation:
nth root(54 . x^6 . y^ 12) = 3 x^2 y^4 nth root of 2
(54 . x^6 . y^ 12)^1/n = 3 x^2 y^4 2^1/n
54^1/n . (x^6)^1/n . (y^12)^1/n = 3 x^2 y^4 2^1/n
Consider the terms in x:
(x^6)^1/n = x^2
x^6/n = x^2
Therefore 6/n = 2 and n = 3.
Check this out with the constants in the expressions:
54 ^ 1/n = 3 * 2^1/n
54 ^ 1/3 = 27^1/3 * 2^1/3 = 3 * 2 1/3
- Checks OK.
