Answer:
<h2>
294 cm²</h2>
Step-by-step explanation:
<span>(A) Find the approximate length of the plank. Round to the nearest tenth of a foot.
Given that the distance of the ground is 3ft.
In order to get the length of the plank,
we can use the this one.
cos 49 = ground / plank
cos 49 = 3 / plank
plank = cos 49 / 3
plank = 0.10 ft
</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>
The remaining angle is equal to
angle = 180 - (90+49)
angle = 41
Finding the height.
tan 41 = height / ground
tan 41 = height / 3
height = tan 41 / 3
height = 0.05 ft.
(A) 0.10 feet
(B) 0.05 feet</span>
Answer:
A. 3 1/24
B. 7/12
C. 3 13/15
D. 1 1/8
Step-by-step explanation:
Answer: 40 is the answer
Step-by-step explanation:
Farmer fertilized 20 trees per day for 10 days=20*10=200
total trees- fertilized tree=leftover trees
520-200=left over trees
320=left over trees
per day fertilized tree=left over trees /8
per day fertilized trees=320/8
per day fertilized trees=40
