Answer:
-6
Step-by-step explanation:
(-2) * (5) = -10
-10+ 4= -6
22 which is simplified to 11
--- ---- of a chance to be on time
26 13
It appears that for every question missed, it deducts 3 points.
so if Julie missed 6 questions, then she received a : (-3 * 6) = -18
Answer:
I believe the answer is the second one but take precaution i haven´t done them in a few years so be careful.
Step-by-step explanation:
(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>
