Mathematics

Answer:

the total area of the rhombus is 80 units².

Step-by-step explanation:

If we draw a horiz. line through the vertices (-1, 1) and (9, 1), we create a triangle with those points and (4, 9) as vertices.  Thus, the base of this triangle is 9 - (-1), or 10, and the height is 9 - 1, or 8.

The area of this triangle is A = (1/2)(base)(height), or

A = (1/2)(10)(8) = 40 units².  Since the lower triangle has the same area, the total area of the rhombus is 2(40 units²), or 80 units².

WRITE AN COMPOUND INEQUALITY FOR THIS SENTENCE
Mila [183]
Hello there!

Write a compound inequality for this sentence: 'w' is less than 4 and greater than or equal to -8
Only use 'w' once.


W is less than four ~ 4 \ \textgreater \ w

W is greater than or equal to -8 ~ w \geq -8

If we were to put this together, it would look like:

4 \ \textgreater \  w  \geq  -8


I hope I helped!

Find the surface area of composite figures
Aleonysh [2.5K]

  • Answer:

<em>429 cm²</em>

  • Step-by-step explanation:

<em>A(blue) =</em>

<em>= 2×6cm×10cm + 2×6cm×8cm + 8cm×10cm + (8cm×10cm - 5cm×4cm)</em>

<em>= 120cm² + 96cm² + 80cm² + 60cm²</em>

<em>= 356 cm²</em>

<em>A(green) =</em>

<em>= 4cm×5cm + 2×5cm×5cm/2 + 4cm×7cm</em>

<em>= 20cm² + 25cm² + 28cm²</em>

<em>= 73 cm²</em>

<em>A(total) =</em>

<em>= A(blue) + A(green)</em>

<em>= 356 cm² + 73 cm²</em>

<em>= 429 cm²</em>
