One. A triangles angles all add up to 180*. so 90*+50*+40*=180*

Explanation:
I think you may have confused parallel and perpendicular for some of the questions. Also, a cube has square sides and base, so any crossection parallel or perpendicular will also be square. I hope this is helpful!

27x + 14 = 3(9x - 7)​
ehidna [41]

Answer:

no solution

Step-by-step explanation:

Given

27x + 14 = 3(9x - 7) ← distribute right side

27x + 14 = 27x - 21 ( subtract 27x from both sides )

0 + 14 = - 21 ( subtract 14 from both sides )

0 = - 35 ← not possible

Thus the equation has no solution

Fraction to Decimal Conversion Tables

Important Note: any span of numbers that is underlined signifies that those numbers are repeated. For example, 0.09 signifies 0.090909....

Only fractions in lowest terms are listed.  For instance, to find 2/8, first simplify it to 1/4 then search for it in the table below.  

 

fraction = decimal      

1/1 = 1      

1/2 = 0.5      

1/3 = 0.3 2/3 = 0.6    

1/4 = 0.25 3/4 = 0.75    

1/5 = 0.2 2/5 = 0.4 3/5 = 0.6 4/5 = 0.8

1/6 = 0.16 5/6 = 0.83    

1/7 =  0.142857 2/7 =  0.285714 3/7 =  0.428571 4/7 =  0.571428

 5/7 =  0.714285 6/7 =  0.857142  

1/8 = 0.125 3/8 = 0.375 5/8 = 0.625 7/8 = 0.875

1/9 = 0.1 2/9 = 0.2 4/9 = 0.4 5/9 = 0.5

 7/9 = 0.7 8/9 = 0.8  

1/10 = 0.1 3/10 = 0.3 7/10 = 0.7 9/10 = 0.9

1/11 = 0.09 2/11 = 0.18 3/11 = 0.27 4/11 = 0.36

 5/11 = 0.45 6/11 = 0.54 7/11 = 0.63

 8/11 = 0.72 9/11 = 0.81 10/11 = 0.90

1/12 = 0.083 5/12 = 0.416 7/12 = 0.583 11/12 = 0.916

1/16 = 0.0625 3/16 = 0.1875  5/16 = 0.3125 7/16 = 0.4375

 11/16 = 0.6875 13/16 = 0.8125 15/16 = 0.9375

1/32 = 0.03125 3/32 = 0.09375 5/32 = 0.15625 7/32 = 0.21875

 9/32 = 0.28125 11/32 = 0.34375 13/32 = 0.40625

 15/32 = 0.46875 17/32 = 0.53125 19/32 = 0.59375

 21/32 = 0.65625 23/32 = 0.71875 25/32 = 0.78125

 27/32 = 0.84375 29/32 = 0.90625 31/32 = 0.96875

Need to convert a repeating decimal to a fraction? Follow these examples:

Note the following pattern for repeating decimals:

0.22222222... = 2/9

0.54545454... = 54/99

0.298298298... = 298/999

Division by 9's causes the repeating pattern.

Note the pattern if zeros precede the repeating decimal:

0.022222222... = 2/90

0.00054545454... = 54/99000

0.00298298298... = 298/99900

Adding zero's to the denominator adds zero's before the repeating decimal.

To convert a decimal that begins with a non-repeating part, such as 0.21456456456456456..., to a fraction, write it as the sum of the non-repeating part and the repeating part.

 0.21 + 0.00456456456456456...

Next, convert each of these decimals to fractions. The first decimal has a divisor of power ten. The second decimal (which repeats) is converted according to the pattern given above.

 21/100 + 456/99900

Now add these fraction by expressing both with a common divisor

 20979/99900 + 456/99900

and add.

 21435/99900

Finally simplify it to lowest terms

 1429/6660

and check on your calculator or with long division.

= 0.2145645645...
