Number and Number Relationships. Hel When you think of mathematics, you think
of numbers. Numbers are a very important
part of everyday life. Having good number
sense helps you solve many problems.
Activity
1. How many seconds are there in a day?
a week? a year?
2. How old are you in seconds?
3. If you had a billion dollars and you spent
one dollar every second, how many years
would it take you to spend it all?
Activity ~
The fastest bird on land is the ostrich. It
can run as fast as 80 km/h. Use your research
skills to help answer the following questions.
1. How long would it take an ostrich to run
from Halifax to Vancouver if it did not have
to stop?
2. How long would it take an ostrich to run
to the moon?
3. How long would it take an ostrich to run
to the sun?
Activity 3
The graph shows the precipitation in
Winnipeg and Toronto for one year.
did Toronto have less

4/6 = 2/3

so it should take 3/3 hours per man. so 9 hours is the answer 3*3 =9

step-by-step explanation:

we are given a graph for system of inequalities.

in order to write the system of inequalities for the given graph, we need to find the inequality for each of the line separately.

let us find the slope of dotted line first.

taking two coordinates on the graph.

let us say (0,0) and (3,1).

let us find the slope of the line now.

slope of the dotted line would be =.

y-intercept of dotted line is y=0 only.

plugging slope m= and b=0 in slope-intercept form y=mx+b, we get

.

the line is shaded up of that dotted line.

therefore, for shading up we would take greater than inequality symbol > .

and because it's a dotted line we would take only > symbol in place of = sign in above equation of line.

therefore, inequality for dotted line would be

let us take two points (3,1) and (0,4) on the solid line.

slope of the solid line would be =.

for the solid line we have y-intercept b= 4.

plugging slope m= -1 and b=4 in slope-intercept form y=mx+b, we get

y = -1x + 4.

the line is shaded down of that solid line.

therefore, for shading down we would take less than inequality symbol < .

and because it's a solid line we would take ≤ symbol in place of = sign in above equation of line.

therefore, inequality for solid line would be
