All I can say is 1 and 2 are correct.
Linear relationships can be expressed in a graphical format where the variable and the constant are connected via a straight line or in a mathematical format where the independent variable is multiplied by the slope coefficient, added by a constant, which determines the dependent variable.
Answer:
The man covers 200 ft in 40 seconds.
Step-by-step explanation:
A person is moving on the sidewalk from one end to the other end.
He walks 40 feet in 8 seconds.
Therefore his speed =
=
= 5 ft/
He covers the sidewalk distance at a rate of 5 feet every second.
To calculate the time taken to cover 200 ft,
time =
time =
<u>time = 40 seconds</u>
Hence the man covers 200 ft in 40 seconds.
Answer: 30 inches
Step-by-step explanation:
Given:
ABC-tringle
BH= 8 in - height
S= 120 in^2
AC-?
Solution:
S=1/2ab
120in=1/2a*8in
120=4a
4a=120
a=30 in
