Answer:
942.22
Step-by-step explanation:
0.9(x-20)=830
Distribute .9
.9x -18 =830
Add 18 to each side
.9x -18+18=830+18
.9x = 848
Divide each side by .9
.9x/.9 = 848/.9
x =942.22222222
To the nearest hundredth
942.22
Answer:
i mite be wrong but the 2 choice
Step-by-step explanation:
Answer:
The answer is below
Step-by-step explanation:
The question is not complete. The complete question is:
The 12 foot long bed of a dump truck loaded with debris must rise an angle of 30 degrees before the debris will spill out. Approximately how high must the front of the bed rise for the debris to spill out.
Solution:
Let x be the height of the front of the bed rise needed to be raised for the debris to spill out. We can find x using trigonometric identities. That is:
sin θ = opposite / hypotenuse
Using trigonometric identities, we can get that:
sin(30) = x / 12
This gives:
0.5 = x / 12
Cross multiplying the terms to get:
x = 12 * 0.5
x = 6 ft
Therefore the front of the bed rise must be raised 6 ft for the debris to spill out.
Answer:
144 degrees
Step-by-step explanation:
A straight line adds up to 180 degrees so:2x+8+x-2=180
2x+x+8-2=180
3x+6=180
3x=180-6
3x/3=174/3
X=68
2x+8
2*68+8=144
I don't know honey, but I think it can be the 2nd choice, the answer...
50 miles/1 hour = ? miles/200 miles.
I hope I helped and goodluck :)
