Answer:
So, Simplified fraction of 8:6 is 4:3.
Mid point of the points PQ is (₋0.3 , 3.25)
Given points are:
P(₋2 , 2.5)
Q(1.4 , 4)
midpoint of PQ = ?
A location in the middle of a line connecting two points is referred to as the midpoint. The midpoint of a line is located between the two reference points, which are its endpoints. The line that connects these two places is split in half equally at the halfway.
The midpoint calculation is the same as averaging two numbers. As a result, by adding any two integers together and dividing by two, you may find the midpoint between them.
Midpoint formula (x,y) = (x₁ ₊ x₂/2 , y₁ ₊ y₂/2)
we have two points:
P(₋2,2.5) = (x₁,y₁)
Q(1.4,4) = (x₂,y₂)
Midpoint = (₋2 ₊ 1.4/2 , 2.5₊4/2)
= (₋0.6/2 , 6.5/2)
= (₋0.3 , 3.25)
Hence we determined the midpoint of PQ as (₋0.3 , 3.25)

<span>12 edges and 8 vertices, so 12:8 or 3:2
Hope this helps!</span>
1 and 13/100 i'm pretty sure
Answer:
243 cm^3
Step-by-step explanation:
The faces of a cube are squares.
A = s^2
s^2 = 9 cm^2
s = 3 cm
The side of the square is the edge of the cube and is 3 cm.
V = s^3
V = (3 cm)^3 = (3 cm)(3 cm)(3 cm) = 27 cm^3
The volume of one cube is 27 cm^3.
The volume of 9 cubes is 9 * 27 cm^3 = 243 cm^3
Answer: 243 cm^3
