Given:
The graph of a line which represents position (m) at time (s).
To find:
The slope of the line.
Solution:
Formula for slope:
From the given graph it is clear that the line passes through two points (0,0) and (1,4).
Using the above formula, we get
Therefore, the slope of the line is 4 m/s.

Answer:
5
Step-by-step explanation:
Divide 30 by 6, since this will find the number of chairs she can paint in 1 minute:
30/6
= 5
So, the constant of proportionality is 5, since she can paint 5 chairs in a minute.
Answer:
By themselves $18.20, $13.60, and together $31.80
Step-by-step explanation:
$2.60 multiplied by 7 equals $18.20
$3.40 multiplied by 4 equals $13.60
Together this equals $31.80
Answer: 17.9
Step-by-step explanation:
Using Heron's formula:
Area of a triangle is given by:
√s(s-a)(s-b)(s-c)
Where a, b and c ara sides of the triangle and
S = (a+b+c) / 2
In the question above sides are :
XY=XZ= 20 and YZ=18
S = (20 + 20 + 18) / 2 = 58/2 = 29
Area = √29(29-20)(29-20)(29-18)
Area = √29(9)(9)(11)
Area = √25839
Area = 160.74513
Altitude = height(h)
Area = 0.5 × base × height
Base = yz = 18
160.74513 = 0.5 × 18 × h
160.74513 = 9 × h
h = 160.74513 / 9
h = 17.9 (3 s.f)
