This is a linear, non-proportional relationship.
It is linear because there is a constant slope, or rate of change.
It is not proportional because it does not go through the origin. The y-intercept would be the $25 starting fee.
Answer:
The answer to your question is the third choice 4 / (3d - 12)
Step-by-step explanation:
Data
length = (d -2 ) / (3d - 9)
width = 4/(d - 4)
height = (2d - 6)/(2d - 4)
Process
1.- Multiply the numerators
(d - 2)(4)(2d - 6) = 8(d - 2)(d - 3)
2.- Multiply the denominators
(3d - 9)(d - 4)(2d - 4) = 6(d - 2)(d - 4)(d - 3)
3.- Simplify
8(d - 2)(d - 3) / 6(d - 2)(d - 4)(d - 3)
8 / 6(d - 4)
Simplify 8/3 = 4/3
4/3(d - 4)
Answer:
The perimeter of the trapezoid is
Step-by-step explanation:
we know that
The perimeter of the trapezoid is the sum of its four side lengths

step 1
Find the distance QR
substitute the values in the formula
step 2
Find the distance RS
substitute the values in the formula
step 3
Find the distance ST
substitute the values in the formula
step 4
Find the distance QT
substitute the values in the formula
step 5
Find the perimeter
Answer:
B
Step-by-step explanation:
You need to find x, so you'll have to use cos in this case, because x is adjacent to the only angle you have.
So, you'll get:
cos 30 = x/10 (adjacent/hypotenuse)
Rearrange the equation for x:
x = cos 30 x 10
<em>*Since the options you have are in exact values, you can't use a calculator just to find x. </em>
Cos 30 in exact values is √3/2
<em>*you can either memorise these values or learn the trig triangles. either way, just know the exact values for sin, cos and tan for 30, 60 and 90 degrees</em>
So to find x:
x = √3/2 x 10
x = 5√3
