Answer:

x=0.4

Step-by-step explanation:

combine like terms

7x+8 = 12 - 3x

10x = 4

divide both sides by 10

x=4/10

x=2/5

the width of the vegetable garden is 1/3 times its length. if the length of the garden is 7 3/4, what is the width in simplest f
Valentin [98]

w = width

l = length

w = 1/3 length

l = 7 3/4


w = 1/3 * length

w = 1/3 ( 7 3/4)

change the mixed number to an improper fraction

7 3/4 = (4*7+3)/4 = 31/4

w = 1/3 ( 31/4) = 31/12

12 goes in to 31 2 times with 7 left over

w = 2 7 /12

World problem in length (trigonometry) geometry not chemistry
lions [1.4K]

Answer:

≈ 47.2 m

Step-by-step explanation:

let the height from the sea to the base of lighthouse be h₁

let the height from the sea to the top of the lighthouse be h₂

using the tangent ratio in the right triangle

tan55.1° = \frac{opposite}{adjacent} = \frac{h_{1} }{610} ( multiply both sides by 610 )

h₁ = 610 tan55.1°

tan56.5° = \frac{h_{2} }{610} ( multiply both sides by 610 )

h₂ = 610 tan56.5°

then

height of lighthouse = h₂ - h₁        

                                  = 610 tan56.5° - 610 tan55.1°

                                  = 610(tan56.5° - tan55.1° )

                                 ≈ 47.2 m ( to the nearest tenth )
