equivale a doce unidades, por ejemplo:
tengo 12 huevos = tengo una docena de huevos, pero tambien se pueden acumular, por ejemplo:
tengo 24 canicas = tengo 2 docenas
y para sacar las docenas solo divides el numero o las unidades entre 12

Answer:
C. 0.6625 square inches
Step-by-step explanation:
To get the area of the net of a square pyramid;
We need to find the are of the square base and the area of the four triangles;
Area of the square base = s²
= (0.25 in)²
= 0.0625 in²
Area of one triangle = 0.5 × b × h
= 0.5 × 0.25 in × 1.2 in
= 0.15 in²
Area of the four triangles = 0.15 in² × 4
= 0.6 in²
Therefore;
Area of the net square pyramid = 0.0625 in² + 0.6 in²
= 0.6625 square inches
Answer:
Absolute error is 0.05 cm.
Step-by-step explanation:
Given:
Actual length = 12.25 cm
Measured length = 12.2 cm
We need to find Absolute error.
Solution:
Now we can say that;
Absolute error is equal to measured length minus Actual actual.
framing in equation form we get;
Absolute error = 
Hence Absolute error is 0.05 cm.
<h3>
12 = -5x/4 - 8</h3>
Multiply both sides of the equation by 4.
<h3>48 = −5x − 32</h3>
Swap the sides so that all variable terms are on the left side.
<h3>−5x − 32 = 48</h3>
<em>Add 32 to both sides.</em>
<h3>−5x = 48 + 32</h3>
<em>Add 48 and 32 to get 80.</em>
<h3>−5x = 80</h3>
<em>Divide both sides by −5.</em>
<h3>x = 80/-5</h3>
<em>Divide 80 by −5 to get −16.</em>
<h3>x= −16</h3>
