Answer:
$2.50
Step-by-step explanation:
Let's set up a proportion using the following setup.
price / pens = price / pens
We know that it costs $4.00 for 8 pens.
$4.00 / 8 pens = price / pens
We don't know how much it costs for 5 pens. Therefore, we can say it costs $x for 5 pens.
$4.00 / 8 pens = $x / 5 pens
4/8=x/5
We want to solve for x (the cost for 5 pens). Therefore, we must get x by itself on one side of the equation. x is being divided by 5. The inverse of division is multiplication, so multiply both sides of the equation by 5.
5*(4/8)=(x/5)*5
5*(4/8)=x
5*0.5=x
2.5=x
x= $2.50
Ivan should pay $2.50 for 5 pens.

too freaking small dude
Step-by-step explanation:
The linear function that maps the relation between kinetic energy and mass is given at the end of the question.
<h3>What is the kinetic energy of an object?</h3>
The kinetic energy of an object is given by the following formula:
E = 0.5mv².
In which:
- m is the mass of the object.
- v is the velocity of the object.
In this problem, we suppose a velocity of 2.5 m/s, hence the kinetic energy is:
E = 0.5m(2.5)² = 3.125m.
Hence the graph is plotted at the end of the answer.

Complete question is;
The lengths of two sides of a right triangle ABC are given.
Find the length of the missing side.
b = 16 ft and c = 30 ft
Answer:
25.377 ft
Step-by-step explanation:
From online sources, c is the hypotenuse of the triangle.
Thus, we can use pythagoras theorem to solve for the other side of the right angle triangle.
c² = a² + b²
Where a is the length of the missing side.
Thus;
30² = a² + 16²
a² + 256 = 900
a² = 900 - 256
a² = 644
a = √644
a = 25.377 ft
