Answer:
Height of the silo = 18 feet.
Step-by-step explanation:
From the figure attached BC is the length of the silo and the height of the farmer is 5 ft.
Farmer is standing at 8 ft distance from the silo.
From triangle AEC,
tan(∠CAE) = CE/AE=5/8
m(∠CAE) = tan-1 (5/8)
= 32°
m∠BAE = 90° - 32° = 58°
From the triangle ABE,
tan58° = BE/AE
BE = 8tan58°
BE = 12.8 ft
Total height of the silo = BE + EC
= 12.8 + 5
= 17.8
≈ 18 ft
Therefore, the total height of the silo is 18 ft.

Answer:
<u>The knitting club has 7 members </u>
Step-by-step explanation:
1. Let's check the information provided to us to answer the question correctly:
Cost of new patterns book = US$ 3.50
Cost of set of knitting needles for each member = US$ 3.20
Cost of set of a ball of yarn for each member = US$ 3.20
2. Write and solve an equation to determine how many members the knitting club has.
Number of members of the knitting club = x
For solving for x, we can use this equation:
3.50 + 3.20x + 5.40x = 63.70
8.60x = 63.70 - 3.50
8.60x = 60.20
x = 60.20/8.60
x = 7
<u>The knitting club has 7 members </u>
Answer: 70
90+20=110
180-110=70
I hope this is good enough:
7/2 = 63/g..7 red apples to 2 green apples = 63 red apples to g green apples
cross multiply
(7)(g) = (2)(63)
7g = 126
g = 126/7
g = 18
so they sold 63 red apples and 18 green apples...for a total of (63 + 18) = 81 apples sold
