1. 5x= -80. x= -16
2. x - 73 = 129. x = 202
3. x/-8 = 22. x = -176
4. 2x + 8 = 8. 2x = 0. x = 0
5. 3x - 7 = 40. 3x = 47. x = 47/3
80.75 I think
Explanation:
You should do base • height
The amount he would make per hour is $12.60
(A) Find the value of x. Round to the nearest tenth of a degree<span>
Given that the distance of the ground is 9ft.
Length of the plank is 41 ft
In order to get the angle formed between the ground and the foot of the plank,
cos (theta) = ground / plank
cos (theta) = 9 / 41
</span><span>cos (theta) = 0.21951...
</span>theta = cos^-1(<span>0.21951...)
</span><span>theta = 77.3 degrees
</span><span>(b) Find the height above the ground where the plank touches the wall. Round to the nearest tenth of a foot.
</span><span>
Height = square root (plank^2 - ground^2)
Height = square root (41^2 - 8^2)
</span><span>Height = square root (1600)
</span><span>Height = 40
(A) 77.1 Degrees
(B) 40 feet</span>
The appropriate response response will be C since after 5 am to 7 am just two hours have passed so x=2 and afterward you connect it to the x as 2 and understand it. You may find a not correct solution like 39.785, but rather it rounds to 40.
