Answer:ill help all triangles should equal to 180 hope it did help you
Step-by-step explanation:
Answer:
y = 16
Step-by-step explanation:
Given that y varies directly as x then the equation relating them is
y = kx ← k is the constant of variation
To find k use the condition y = 48 when x = 6, thus
k = 
= 
= 8
y = 8x ← equation of variation
When x = 2, then
y = 8 × 2 = 16
No because you have to add all the results in each sample from 1-4+ together . meaning that in sample 1 , 38 people have 0 however 62 people have 1+
Answer:
48.5
Step-by-step explanation:
The constant of proportionality in this case is the speed at which Andrew travels.
We know that the speed is equal to:
v = d / t
We know the distance that is 145.5 miles and the time is 3 hours, replacing:
v = 145.5 / 3
v = 48.5 mi / h
which means that the equation would be:
y = k * x
where k, that is, the constant of proportionality is the velocity 48.5.
y = 48.5 * x
To check if for example x is worth 3, it would be:
y = 48.5 * 3
y = 145.5
Opposite sides of any rectangular face are parallel, because opposite sides of a rectangle are parallel.
Since HCDE is a rectangle, CD ║ HE.
Since ABCH is a rectangle, AB ║ HC.
