Answer:
x = 6 m
Step-by-step explanation:
The area (A) of a trapezium is calculated as
A = 
h (a + b)
where h is the perpendicular height and a, b the parallel bases
Here A = 60, h = 8, a = 9 and b = x , thus
× 8 × (9 + x) = 60, that is
4(9 + x) = 60 ( divide both sides by 4 )
9 + x = 15 ( subtract 9 from both sides )
x = 6 m
Answer:
Domain: 
Step-by-step explanation:
Given
Required
Determine f(x) and its domain
To determine f(x), we replace 5x with x in f(5x)
So, we have:
Take LCM
To get the domain, we set the denominator as
Answer:
Step-by-step explanation:
p + 3d = 9.50
3p + 4d = 19.75
-3p - 9d = -28.50
3p + 4d = 19.75
-5d = -8.25
d= $1.65 drinks
p + 3(1.65) = 9.50
p + 4.95 = 9.50
p = $4.55 popcorn
Hey there,
Length = 4x
Width = 3x
Perimeter = 112 inches
4x + 3x + 4x + 3x = 112 inches
14x = 112 inches
x = 112 inches / 14
= 8 inches
Length = 8 inches x 4
= 32 inches
Width = 8 inches x 3
= 24 inches
Hope this helps :))

Answer:
19.0681
Step-by-step explanation:
Given in the question that,
angle from ted to the dog = 60° with the ground
height of ted from the ground = 16ft
To find,
distance between dog and the door of ted's building
Considering the scenario make a right angle triangle:
<h3>By using pythagorus theorem:</h3>
Tan 40 = opposite / adjacent
Tan 40 = height / distance between dog and the door
Tan 40 = 16ft / x
x = 16 / tan40
x = 19.068057
x ≈ 19.0681 (nearest to thousand)
So, the dog need to walk 19.0681ft to reach the open door directly below Ted.
