Yesthe value of 4 in 46,395 36 times the value of 4 in 14,906
Answer:
the value of x-1/x is given down
Step-by-step explanation:
=(x+1/x)²=x²+1/x²+2
=(5)²=x²+1/x²+2
=x²+1/x²=25-2
=x²+1/x²=23 this is the answer
if u ask there how 25 came means there (5)² is that u should multiply 5×5 and u will get 25bas the answer
81 servings. I found this by making a ratio:
24 c 108 c
------- = -------
18 ser x
I then cross multiplied to get the equation: 24x=1,944. I solved this equation to find x, the number of servings in 108 cups, which was 81.
I remember doing this back in elementary school. I had a hard time with it too!
Given : A submarine descends at a rate of 2.6 kilometers per hour.
If the ocean floor is 6.24 kilometers below sea level,
To Find : how long will it take the submarine to descend to the ocean floor?
Solution:
The submarine descends at a rate of 2.6 kilometers per hour.
Speed = 2.6 km/hr
The ocean floor is 6.24 kilometers below sea level,
Distance to be covered = 6.24 km
Time= Distance / Speed
= 6.24 / 2.6
= 2.4 hr
The submarine will take 2.4 hrs to descend to the ocean floor
