If 2a = 3 + 2b, prove that 8a3 – 8b3 – 36ab = 27.
irga5000 [103]

b = -0.5 and a = 1. 2=3+-1. 1 to the third power is just 1, times 8 is 8. -0.5 to the third power is -0.125. -0.125 times 8 is -1. 8 - (-1) is 9. 36 times 1 is 36, times -0.5 is -18. 9-(-18) = 27. I hope this helps! Could I possibly get brainliest?

Find the complement and supplement of the angle with measure 40 degrees
mrs_skeptik [129]

Answer:

The complement is 50 and the supplement is 140

Step-by-step explanation:

Complementary angles add up to 90. Supplementary angles add up to 180. We simply need to subtract to find the difference to fill the gap.

90-40=50

180-40=140

The complement is 50 and the supplement is 140

Travis is cutting strips of paper for a project. He needs strips that are 114 inches wide. He cut his first strip too wide. His
choli [55]

Travis cuts 125 whole 2/5 inches wide strip if the percent of error was 10% the actual length of the strips he needs to cut was 114 inches

<h3>What is the percentage?</h3>

It is defined as the ratio of two numbers expressed in the fraction of 100 parts. It is the measure to compare two data, the % sign is used to express the percentage.

We have:

The length Travis needs to cut = 114 inches

Percent of error = 10%

Let's assume he cuts x inches wide strip

So from the percent of error formula:

\rm \dfrac{x-114}{114} = \dfrac{10}{100}

\rm x = \dfrac{114}{10}+114

\rm x = \dfrac{1254}{10}\Rightarrow \dfrac {627}{5}  or

\rm x = 125\dfrac{2}{5} \ inches  

Thus, Travis cuts 125 whole 2/5 inches wide strip if the percent of error was 10% the actual length of the strips he needs to cut was 114 inches
