Answer:  Last one is right  C = 5 / 9 (F-32)

Step-by-step explanation: Solving  C from equation F = (9/5)C + 32 :

1. multiply by 5     you get   5F = 9C + 160  and 5(F-32) = 9C

2. divide by 9 you get (5/9) (F-32) = C

Question 6 of 9 (3•8) • 1 = 3 • (8.1) O A. True B. False​
olga nikolaevna [1]

Answer:

No, (false). The question I assume was: (3*8)*1=3*(8.1)

Step-by-step explanation:

1. Multiple: 3 * 8 = 24

2. Multiple: <em><u>The result of step No. 1:</u></em> * 1 = 24 * 1 = 24

3. Conversion a decimal number to a fraction: 8.1 = \frac{81}{10} = \frac{81}{10}

   a) Write down the decimal 8.1 divided by 1: 8.1 = \frac{81}{1}

   b) Multiply both top and bottom by 10 for every number after the

       decimal point. (For example, if there are two numbers after the decimal

       point, then use 100, if there are three then use 1000, etc.)

       \frac{8.1}{1} = \frac{81}{10}

   Note: \frac{81}{10} is called a decimal fraction.

   c) Simplify and reduce the fraction

       \frac{81}{10} = \frac{81*1}{10*1} = \frac{81}{10}

4. Multiple: 3 * 8.1 = \frac{3*81}{1*10} = \frac{243}{10}

   Multiply both numerators and denominators. Result fraction keep to lowest

   possible denominator GCD(243, 10) = 1. In the next intermediate step the

   fraction result cannot be further simplified by canceling.

   In words - three multiplied by eighty-one tenths = two hundred forty-three

   tenths.

5. Compare: <em><u>The result of step No. 2 </u></em>vs <em><u>The result of step No. 4</u></em>: = 24 vs \frac{243}{10} = \frac{24}{1} vs \frac{243}{10} = \frac{24*10}{1*10} vs \frac{243}{10} = \frac{240}{10} vs\frac{243}{10} = 240 vs 243 = No

An airplane started at point K, travelled 560 miles to point L, adjusted its route and travelled another 575 miles to point M. I
S_A_V [24]

Answer:

Step-by-step explanation:

Using the cosine theorem:

c^{2} =a^{2} +b^{2} -abcos\beta

952^{2} =560^{2} +575^{2} -560*575cos\beta

\beta =cos^{-1} (\frac{560^{2}+575^{2}-952^{2}   }{2*560*575} )

The angle is 114.014 degrees if we substract 90 degrees it means that at point L the plane changed its angle by 24 degrees

Mean is when you take all the numbers and add them together and divide by the amount of numbers there

Example: Find the mean of :3,4,6,7

So you a 3+4+6+7=20 divide that by 4(because there you added 4 numbers) and that equals 5
