What is the midpoint of the line segment with endpoints (–5.5, –6.1) and (–0.5, 9.1)?

astraxan [27]

$\bf ~~~~~~~~~~~~\textit{middle point of 2 points }
\\\\
(\stackrel{x_1}{-5.5}~,~\stackrel{y_1}{-6.1})\qquad 
(\stackrel{x_2}{-0.5}~,~\stackrel{y_2}{9.1})
\qquad
% coordinates of midpoint 
\left(\cfrac{ x_2 + x_1}{2}~~~ ,~~~ \cfrac{ y_2 + y_1}{2} \right)
\\\\\\
\left( \cfrac{-0.5-5.5}{2}~~,~~\cfrac{9.1-6.1}{2} \right)\implies \left( \cfrac{-6}{2}~~,~~\cfrac{3}{2} \right)\implies \left(-3~,~1\frac{1}{2} \right)$

Find the missing number in this proportion.<br><br> 7 2<br> = <br> 4

borishaifa [10]

Answer:

x = 14

Step-by-step explanation:

I don't know which one you are supposed to solve it by so I will do both.

Solution by Cross Multiplication

For the equation

7x=24

The cross product is

7×4=x×2

Solving for x

x=7×42

and reducing

x=14

Solution by Proportion

Since the equation is an equality

If

7 ÷ 2 = 3.5

Then it is true that

x ÷ 4 = 3.5

Solving for x

x = 4 × 3.5

x = 14

4. The dimensions of a triangular pyramid are shown below. The height of

lyudmila [28]

Answer:

<h2>The volume of the pyramid is 5 cubic inches.</h2>

Step-by-step explanation:

Assuming that the triangle base dimensions are 1 inche and 5 inches, and the height of the pyramid is 6 inches, the volume would be

$V=\frac{1}{3}Bh$

Where $B$ is the area of the base (triangle) and $h$ is the height.

$B=\frac{1}{2}bh =\frac{1}{2}(1)(5)=2.5 \ in^{2}$

Then,

$V=\frac{1}{3}(2.5)(6)=5 \ in^{3}$

Therefore, the volume of the pyramid is 5 cubic inches.
