The grade on the west side would be the vertical rise divided by the horizontal run or 525 divided by 800' or rounded off to 66% (a steep grade as in an underground mine a grade of 25% is considered very steep for vehicles to go up or conveyors to travel). On the east side the 40% grade was obtained by dividing the 525' vertical height by the 1300' run.

Answer:

21/32, or 66%; and 21/52, or 40%.

Step-by-step explanation:

Grade is the same as slope, which is rise/run.

For the west side, the rise is 525 and the run is 800; this gives us

525/800 = (525÷25)/(800/25) = 21/32 = 0.66 = 66%

For the east side, the rise is 525 and the run is 1300; this gives us

525/1300 = (525÷25)/(1300÷25) = 21/52 = 0.40 = 40%

For what values of b the relation R:{(b^2, 5), (5b, 6)} is not a function?
xenn [34]

Answer:

B=5,0.

Step-by-step explanation:

It's not that hard. It's just that it might throw you off a bit with the R and the other things. Functions if you don't remember are where the coordinates don't have the same x and y. So since the y1 and y2 are different then to make it not a function, you have to make x1 and x2. To make it that b would have to be = to 5 and 0.

Next value 4 D 7 G 10 J 13
ValentinkaMS [17]
Hello,
 
In this pattern you can notice that  the numbers and letters alternate, 1 by 1. Also, from each number to the next, 3 is added. (4 + 3 = 7, 7 + 3 =10, 10 + 3 = 13). For the letters, it goes in alphabetical order with two letters being skipped between each letter. (D, G, J). 

Based on the number letter pattern, the last value is a number indicating a letter is next. Now, we just follow the same "skip two" letters pattern to get from J to M.

I believe M is the answer.
Hope this helps!
