We can write the two given inequalities as:
0 < x < 1/3
And the graph of it can be seen below.
How to graph the inequalities?
Here we want to graph the inequalities:
x < 1/3
x > 0.
To do it, we can rewrite the inequality as:
0 < x < 1/3.
To graph this, we need to work with a number line. First, we will mark both of the ends of the inequality, that is x = 0 and x = 1/3, both will be graphed with open circles, which means that these points are not solutions. Then, we need to shade the region between these points.
The graph can be seen below.

6 Jamila uses a tape measure to find the length of her desk. It is 1 metre 8.5 centimetres. Write this in metres.
Answer:
1.085 metres
Step-by-step explanation:
1 cm = 0.01 m
8.5 cm = 0.085 m
1m+0.085m=1.085 metres
Answer:
1.085 metres
Step-by-step explanation:
100 centimetres = 1m
what about 8.5 cm?
Divide the centimetres by 100
8.5/100 = 0.085m
Then add the metre(s) you already have which is 1
thus 0.085 + 1
1.085m

Step-by-step explanation:
the equation is
3x + 5y = 18
the blue dot is the interception of the line with the y-axis. that is the y value, when x = 0.
the equation for x = 0 is
3×0 + 5y = 18
5y = 18
y = 18/5 = 3 3/5 = 3.6
the red dot is the interception of the line with the x-axis. that is the x value, when y = 0.
the equation for y = 0 is
3x + 5×0 = 18
3x = 18
x = 18/3 = 6
so, you need to move the blue dot to 3.6 and the red dot to 6.

let n (AUB)=32n(B)=16and n(ANB)9 find n (A)
Answer:
32
Step-by-step explanation:
n(A∪B)=n(A)+n(B)−n(A∩B)−−−−−−−(1)
Given n(A)= ? we represent with x
n(B)= 16
n(A∪B) = 32
Substituting in equation 1 to get n(A)
32 = n(A) + 9 − 9
⇒n(A) = 32 − 0
n(A) = 32
to confirm this we put the values into the formula below
n(A∪B)=n(A)+n(B)−n(A∩B)−−−−−−−(1)
32 = 32 + 9 - 9
Answer:
n(A) = 25
Step-by-step explanation:
The relation between cardinality of two sets and that of their union and intersection is ...
n(A∪B) = n(A) +n(B) -n(A∩B)
32 = n(A) +16 -9 . . . . . use the given information
25 = n(A) . . . . . . . . . subtract 7

There are 150 people ina golf club.a) there are 50%more men than women in the golf club. How many mena nd how many women are ther in the golf club.
The percentage computed shows that the number of women is 60 while men are 90.
How to calculate percentage?Let the number of women be represented by x.
Since there are are 50% more men than women in the golf club, the number of men will be:
= x + (50% × c)
= x + 0.5x
= 1.5x
Therefore, 1.5x + x = 150
2.5x = 150
x = 150/2.5
x = 60
Number of women = 60
Number of men = 1.5x = 1.5 × 60 = 90

Explanation:
One way to draw out the diagram is shown below.
Focus on the right triangle.
tan(angle) = opposite/adjacent
tan(x) = 3/12
tan(x) = 0.25
x = arctan(0.25)
x = 14.03624

Six times the quotient of thirty-two and
eight, increased by seven
Answer:
[tex]6*\frac{32}{8}+7[/tex]
Step-by-step explanation:
The required expression, six times the quotient of thirty-two and
eight, increased by seven, is given as x = 6(32/8) + 7.
What is simplification?The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.
Here,
Let the expression equal to x,
According to the question,
Six times the quotient of thirty-two = 6(32 /8)
Increased by seven = 6(32 /8) + 7
X = 6(32 /8) + 7
Thus, the required expression, six times the quotient of thirty-two and
eight, increased by seven, is given as x = 6(32/8) + 7.
