Answer: c= 0.79p
Step-by-step explanation:
Divide each cost by the number of pens it have to find the constant change value.
3.95/5 = 0.79
7.90/10= 0 .79
11.85/15 = 0.79
15.80 / 20 = 0.79
Since the constant change is 0.79 which means that for each pen it will cost you $0.79, then the equation will be c= $0.79p where c is the cost and p is the number of pens.
Using the concept of an one-to-one function, it will be one-to-one for c = 13.
<h3>What is an one-to-one function?</h3>
A function is said to be one-to-one if each output is mapped to only one input.
In this problem, outputs 2, 5 and 11 have already been matched to inputs 1, 3 and 5, respectively, hence the output for input 6 has to be c = 13 for a one-to-one function.

Answer:
d = 102° , e = 56° , f = 22°
Step-by-step explanation:
d and 102° are vertically opposite angles and congruent , so
d = 102°
e and 56° are vertically opposite angles and are congruent , so
e = 56°
f, d and e lie on a straight line and sum to 180° , then
f + d + e = 180° , that is
f + 102° + 56° = 180°
f + 158° = 180° ( subtract 158° from both sides )
f = 22°
Answer:
10 map squares.
Step-by-step explanation:
We have been given a histogram, which represents the plant species spotted in the animal reserve.
The x-axis represents the number of plant species and y axis represents the number of map squares.
We can see that 0 to 9 species are spotted in 1 map square.
10 to 19 and 20 to 29 plant species are spotted in 2 map squares.
To find the number of map squares that spot more than 29 plant species, we will count number of map squares that spot 30 to 49 plant species as 30 to 49 numbers are more than 29.
We can see from our histogram that 4 map squares spot 30 to 39 plant species and 6 map squares spot 40 to 49 plant species.
Therefore, 10 map squares spot more than 29 plant species.
