Answer:
Erin ran 12.5 miles
Luis ran 7.5
In all they ran 20 miles.
Step-by-step explanation:
Erin: 5 x 3.5 = ?
Luis: 3 x 2.5 = ?
----------------------------
5 x 2.5 = 12.5 . Erin ran 12.5 miles
3 x 2.5 = 7.5 . Luis ran 7.5 miles
7.5 + 12.5 = 20 miles
They ran 20 miles all together.
Hope this helps!

<h3>What is Pythagoras theorem?</h3>
Pythagorean theorem, the well-known geometric theorem that the sum of the squares on the legs of a right triangle is equal to the square on the hypotenuse .
The Pythagoras theorem which is also referred to as the Pythagorean theorem explains the relationship between the three sides of a right-angled triangle. According to the Pythagoras theorem, the square of the hypotenuse is equal to the sum of the squares of the other two sides of a triangle.
example:
The hypotenuse of a right-angled triangle is 16 units and one of the sides of the triangle is 8 units. Find the measure of the third side using the Pythagoras theorem formula.
Solution:
Given : Hypotenuse = 16 units
Let us consider the given side of a triangle as the perpendicular height = 8 units
On substituting the given dimensions to the Pythagoras theorem formula
Hypotenuse^2 = Base^2 + Height^2
16^2 = B^2 + 8^2
B^2 = 256 - 64
B = √192 = 13.856 units
Therefore, the measure of the third side of a triangle is 13.856 units.
given:
base= 2.5 ft,
perpendicular= 12 ft
Using Pythagoras theorem,
H² = B² + P²
H² = 2.5² + 12²
H² = 6.25+ 144
H= 12.25 ft

Answer:
Step-by-step explanation:
Ratio is an expression that shows the relationship between two items in terms of quantity. It shows how much of one item can be found in another.
Simon used 3 pears and 9 apples to make a fruit salad.
This is expressed in terms of quantity.
The ratio of the number of pears which simon used to the number of apples which simon used will be
Number of pears which simon used ÷ the number of apples which simon used.
The ratio is 3/9.
Simplifying further to its lowest term,
It becomes 1/3
This is done by dividing the numerator and denominator by 3
