$ 7 dollar reduction....that means new price is (32 - 7) = 25
percent decrease = (original number - new number) / original number..* 100
(32 - 25) / 25....* 100
7/25 * 100
0.28 * 100
28% decrease <==
Answer:
Step-by-step explanation:
The engineer can use a clinometer to measure the angle of elevation of the top of the tree. Let the height of the tree be represented by x, the she could determine the distance across the river, d, by applying the trigonometric function.
Tan θ = 
= 
the the distance, d = x ÷ Tan θ
Assume the angle of elevation of the top of the tree is 
, and the height of the tree is 10 m, then the distance, d, across the river would be;
d = 
= 17.3190
d = 17.32 m
The sketch to the explanation is attached to this answer for more clarification.
It would be the second choice or letter B - (0,12)
To get the y-intercept, set x as zero. Substitute then simplify. Negative six times negative two would equal to positive twelve.
Set: x = 0
Solution: f(x) = (0 - 6) (0 - 2)
f(x) = -6 x -2
Answer: y = 12
Answer:
8.3 cm
Step-by-step explanation:
1. Find the volume of the small cylinder (volume of a cylinder = πr² · h)
π(4.5²) · 17 = 1080.945 cm³
2. Set up the equation to find the volume of the big cylinder
πr² · 5 = 1080.945
3. Divide both sides by 5
πr² = 216.189
4. Divide both sides by π (3.14)
r² = 68.85
5. Square root both sides
r = 8.3 cm (rounded to the nearest tenth)
