Assuming it's the amount of minutes you can call per month:
9.48 - 4 is 5.48
5.48 ÷ 0.25 is 21 point something. Since you have to round down, 21 minutes is the Max amount of time you can call.
Answer:
If it is $10,570 then the answer is 1510, but if you made a typo and meant 105,700, then the answer is 15100.
speed of the plane in still air is 76 m/s and speed of the wind is 28 m/s .
<u>Step-by-step explanation:</u>
Here we have , A plane traveled 1248 miles to Ft. Worth and back. The trip there was with the wind. It took 12 hours. The trip back was into the wind. The trip back took 24 hours. We need to find What is the speed of the plane in still air? What is the speed of the wind? Let's find out :
<u>For Going trip :</u>
Let speed of plane be u , and wind be v so : Speed = ( Distance ) / ( time )
⇒ 
⇒ 
...........(1)
<u>For Returning Trip :</u>
⇒ 
⇒ 
...........(2)
Adding both equations we get :
⇒ 
⇒ 
⇒ 
Putting this value in equation (1) we get :
⇒ 
⇒ 
Therefore , speed of the plane in still air is 76 m/s and speed of the wind is 28 m/s .
Answer:
6^5 * 9^5
Step-by-step explanation:
( 6*9) ^5
We know that ( ab) ^c = a^ c* b^c
6^5 * 9^5
Answer:
3/24 = 7/x
c = $56
Step-by-step explanation:
A percent proportion is just basically a ratio, I could also write this as 3:24 = 7:x, it really doesn't matter. What does matter is that this is considered a percent proportion. Now, to solve a percent proportion, we have this formula.
a/b = c/d
Say b is the unknown value, we would do (a*d)/c, say a was the unknown value, we would do (b*c)/d, Basically, A and D are linked together and B and C are linked together so you take the two values that are linked together first, multiply them together, and divide by the pair that has a partner that is unknown.
